Carbohydrates and muscle mass
What does "muscle-sparing" mean? It's neither linked or explained in the text. —Preceding unsigned comment added by Enkrates (talk • contribs) 21:54, 11 July 2004
 * Exercise uses up a muscle cell's glycogen reserves. Carbohydrates allow muscle cells to refuel. Without enough carbohydrates in your diet, you will lose muscle mass from exercising. According to this essay, it is ideal to exercise 1.5 to 2 hours after a meal, and to have a meal sometime after exercise to refuel your muscle cells. Chira 19:22, 3 Mar 2005 (UTC)

No Pain, No Gain?
is this part really necessary???? i know when i train it hurts, i know it doesnt hurt as in injury - but its pain nevertheless, i personally think the statement is too subjective and doesnt fit within the article. —Preceding unsigned comment added by Weightshead (talk • contribs) 3:45, 7 April 2005
 * I agree, lactic acid creates a "burning" effect and just lifting a heavy weight creates a feeling that could be described as pain. "No pain, no gain" could also be thought of just referring to the exhaustion that one feels after exercise. --Slux 16:58, 7 Apr 2005 (UTC)

Copywrite
Under the section of Myths: Both "Spot Reduction" and "Muscle and fat tissue" sounds similar to that written in Physiology of Fitness by Brian J Sharkey (3rd ed). I have the 2nd ed at home and will check with that. In the mean time, if anyone else could check I would recommend doing so. (I am speaking from memory at the moment).

Training Effect
I created an article on Training Effect, linked it to two existing articles (Dr. Kenneth H. Cooper and Cooper test), and put a link to it here under see also. The article is in a "stub" state and it is probably premature to expand it into text in this article. Simesa 19:29, 23 August 2005 (UTC)

Exercise hypertension
This phenomenon should be noted somewhere. It is apparently well-known that a significant number of otherwise-healthy people (but often having mild hypertension) get spiking of their systolic to high values (250mm or so ) during moderately vigorous exercise (100W typical). Excessive diastolic rises are also often seen. There is some recent Johns Hopkins work, and other earlier stuff (eg D Kraus 1989 in Drugs, IIRC - Management of Hypertension in Actively Exercising Patients). Linuxlad 12:00, 26 August 2005 (UTC)

Why does the opening paragraph read ike a disambiguation page?
The opening paragraph might need to be reworked per Lead section Dalf | Talk 04:22, 24 January 2006 (UTC)
 * Hrm... you have a point there, the article is generally about physical exercise. Before making any changes, I think we should find any possible wikis for the other ambiguous 'exercise' terms to link to them at the top, as some articles do have a mini-disambiguation statement linking to other articles without sacrificing the whole page to disambiguation. --Tyciol 05:03, 24 January 2006 (UTC)
 * If one of the topics covered is the main thrust of the article you can create Exercise (disambiguation) and move the disambiguation tasks there. This might involve splitting some sections out form here.  Alternately I have seen a number of articles where the topics can all be covered in a relatively short space (Which is what this article looks like it is doing).  In that case simply reworking the intro so that it is in paragraph format and not a list and ties them all together briefly addressing each one, should suffice.  Personally I think if you decide to go that way eventually someone will suggest that the article be split.  I can imaging an article on physical exercise demanding a full length article all on its own.  There have been enough books written on it anyway.  You might also consider making this page a disambiguation page and moving the bulk of the article to Physical exercise (which incidently currently redirect here). Dalf | Talk 05:19, 24 January 2006 (UTC)
 * That's a great idea, if there's already a page up. I guess maybe give it some time and fix this article up for the move? That way anyone with this on their watch list can voice any objections. Otherwise say... Feb 1, make the move? All those who say nay are assumed to say I! Oh... *fixes a little unnecessary text* --Tyciol 05:31, 24 January 2006 (UTC)
 * I am not sure how to best execute moves to articles that already exist (even if they are a redirect to the current article). If you want to save the history and talk page hitory you have to get an admin to do it.  There is a page for requesting moves.  I will poke around and if no one objects I will put the request in, in a day or so.  We should wrtie up exactly what we want to do here and add the  or relavent split templates on this talk page to get peoples attention. Dalf | Talk 07:32, 24 January 2006 (UTC)
 * Yes, a complicated issue, but at least we're not looking at a merge :p Imagine what hell that would be to undertake. I think this would be a positive step though. Once moved, we can either use exercise as a redirect to physical exercise, or link to it as a disambiguation that uses other definitions of exercise. For exmaple umm... well, in schooling an activity can often be called an exercise, in one's skills rather than necessarily physical, and to exercise one's rights... I bet Wiktionary could help :p --Tyciol 09:25, 31 January 2006 (UTC)

Physician consultation
'Despite a common belief that only overweight people need a physical before beginning an exercise program, apparently healthy people can still have unknown medical conditions, such as a heart murmur, that can cause severe injury or death' I really don't like how this sentence is worded. It indicates that a heart murmur is always a serious condition when in fact it is very minor. I have had a murmur all my life and I run marathons, compete in triathlons and play football regularly. How about: 'Despite a common belief that only overweight people need a physical before beginning an exercise program, apparently healthy people can still have unknown medical conditions, such as a heart murmur, that in some cases may cause injury or death'?

Redirected
Copied from Fitness training
 * For the past few hundred years, there has always been at least some form of fitness training. In the beginning of the olympics, olympians would train solely for olympic competition throughout the entire year.  As methods and principles have inevitably changed, there is no doubt that the desire for both physical performance and vanity have not.

Picture and pushups: resolution
This is just going back and forth and turning into an edit war. I will never agree that the central figure is doing a proper pushup, it's a bad example for one. If we continue to keep this picture, I will have to revert it. To resolve it though, perhaps we could replace it with a different picture of pushups, or perhaps a different physical exercise altogether. This is a very silly issue to continue wasting our time over, especially with an upcoming move to physical exercise being imminent. No, they did NOT have to perform a proper pushup to reach an improper pushup position, it doesn't even make sense. I could get into that position by doing a cobra from yoga and straightening up a little, but it wouldn't be proper like the marine on the left's pushup is. Tyciol 06:09, 2 February 2006 (UTC)
 * Agreed. There has been too much wasted effort on this debate. We could easily use the soldier image found here on the right instead and be done with it.

Exercise benefits - Vigorous vs. moderate exercise
There appear to be conflicting results on whether vigorous exercise is any better (or worse) for you than moderate exercise, (at least as far as overall health is concerned). I've written this (non) result in, but the boundaries between low, moderate and vigorous (which I've quoted here as 40% and 70% of VO2max) are from memory.

Vote to move to Physical exercise

 * Please vote if you think this article, Exercise, should be moved to Physical exercise:
 * Agree. This article is about physical exercise. Afterward, this article should be changed to a redirect with a disambiguation page header. Andrewjuren 02:39, 11 March 2006 (UTC)
 * Agree. This is all about physical exercise. I second that it should be a disambiguation exercise, linking to the new physical exercise page, as well as things such as academic exercises, skill-training exercises, relaxation exercises, and so on. Tyciol 06:07, 12 March 2006 (UTC)
 * Agree. makes sense. Dhodges 13:59, 12 March 2006 (UTC)

This is a bad move - there are only two other articles and neither are likely to be targets of those who come or link here. Secondly, the exercise page just redirects here and there is a separate exercise (disambiguation) page already. It should be moved back, just as biological reproduction was moved. Richard001 08:57, 20 August 2007 (UTC)

Why aren't we using the simpler title?
If Exercise is going to redirect here anyway, I see absolutely no value in not simply naming this article Exercise. We can include a dab notice at the top either way. -Silence 06:30, 26 January 2007 (UTC)
 * Good point, I changed the redirect to a disambiguation page for PE and E(f). WLU 12:32, 26 January 2007 (UTC)
 * "E(f)" evidently meant "Exercise (options)" (a financial sense).
 * Per its history, the Dab Exercise was subsequently moved to Exercise (disambiguation), and Exercise is now a Rdr to Physical exercise, as the ToP dab states. --Jerzy•t 22:23, 31 January 2008 (UTC)

Other forms of exercise
There are many forms of exercise. If when exercise is searched for and it leads to this page, it excludes other forms of exercise like Spiritual Exercise. I would say that there needs to be a general page for exercise and links to the various forms of exercises- Physical, Spiritual, etc. Dale Fletcher 18:33, 20 June 2007 (UTC)
 * I reverted the change - though exercise leads here, it is clearly titled physical exercise, and the second template at the top of the page leads to the exercise disambiguation page. Thei is not the appropriate page to have information about spiritual exercise.  --WLU 19:21, 20 June 2007 (UTC)
 * WLU is on the mark, and DF was advocating a dictionary organization for WP, which is not a dictionary. It may be possible to write a significant NPoV article on Spiritual exercise. But very few users will seek its content at Exercise, and those who do will be appropriately served by the existing ToP Dab on the accompanying article and the Dab Exercise (disambiguation). (Spiritual Exercise on the other hand, will be suitable for a Dab headed by The Spiritual Exercises of Saint Ignatius but also including books and mail-order programs marketed under the title Spiritual Exercise, likely to be offered by Pendle Hill, Rosicrucians, Eckankar,(Here's a DYK candidate: "DYK that Paul Twitchell was founded by Sri Harold Klemp in 1965?") etc.) --Jerzy•t 15:51 & 22:34, 31 January 2008 (UTC)

Anecdotal evidence?
Source 10 is a source backing up a sentence about "anecdotal evidence." Anecdotal evidence is not evidence. It's like "baked fried chicken" or "jewish Nazi." I vote for the removal of that sentence and its "source." If there's data behind the claim, then fine. Otherwise, I fail to see what source could possibly back up a nonsensical claim.72.92.16.129 (talk) 21:54, 26 June 2008 (UTC)

History??
There most certainly should be a "history of exercise" in this section. For example, how long have people known about the link between exercise and health/strength? Did exercising become very popular recently (20th century or later) or was it popular in other periods? 129.105.205.252 (talk) 02:13, 18 October 2008 (UTC)

Exercise in teens
This section looks plagiarised, unsourced and not NPOV.

--Exercise in teens-- Childhood obesity has become an epidemic in our country. According to the CDC, “17% of children age 12-19 are overweight.” Some would argue that this is the fault of video games and technology that has become increasingly popular in the past few years. The fact of the matter is that technology may be part of the problem, but it is certainly not the whole story. We are living in a more sedentary world than ever before and our young adults are being raised in this environment. The truly sad part of this story is that inactivity during teenage years has a lasting effect on a child’s health. It can lead to heart disease, diabetes, high blood pressure and high cholesterol. These conditions are all extremely preventable with proper nutrition and physical activity. With just a little physical activity everyday teenagers will have a better chance at leading healthier lives on down the road. The effects of physical activity are wide spread. Physical activity among children and adolescents is important because of the related health benefits such as: cardio-respiratory function, blood pressure control, weight management, cognitive function, and other emotional benefits (Department of Health and Human Services). It can decrease depression rates, lower cholesterol and help with physical appearance. Exercise can help teens to feel better not only physically, but mentally as well. It has been shown to help reduce stress levels and improve brain function in children around the country. Those adolescents who participate in regular physical education are more likely to do better on standardized tests and do better in school overall. Part of the reason why kids are more inactive during their teenage years than any other is that they tend to drop out of organized sports around this time. For those kids who do not continue on with sports they find other things to occupy their time like playing video games or watching television. 124.170.146.113 (talk) 05:57, 9 February 2008 (UTC)

Accuracy of the definition
The introduction currently reads, "Physical exercise is any bodily activity that raises the heart rate above its resting level and enhances or maintains physical fitness and overall health." Is it necessary to raise the heart rate for activity to be construed as physical exercise? That part of the definition was added recently. Elevating the heart rate sounds more like a requirement for aerobic exercise. Does the lede need to be reworded, perhaps back to how it read before the recent addition? Hertz1888 (talk) 22:22, 4 March 2009 (UTC)

Exercise
Exercise is a loosely interpreted word, although it primarily referrs to the bodies reaction to excessive exertion and the beneficial reactions that is the result of the exertion.

Narrower title or broader coverage needed
The title "Physical exercise" goes more or less appropriately with the lead sentence
 * Physical exercise is bodily activity that develops or maintains physical fitness and overall health.

But the article promptly goes astray at the beginning of the next sentence:
 * It is often practiced to ...

which accurately reflects The best remedy for this defect would be paragraph-by-paragraph revisions to add the missing perspectives, and additions of new 'graphs and sections (and then considering whether subdivision is desirable; it's already 20kb). But we go to war against intellectual property and other forces of ignorance with the army of editors we have; in the absence of such a trend, the article would be improved by more thoroughly unmasking those defects, by I for one am not prepared to undertake the revision-in-place of the existing article, but i hope to watch its development enough to continue considering whether to implement the alternative remedy. --Jerzy•t 07:14, 31 January 2008 (UTC)
 * 1) the article's unrelieved but erroneous assumption that physical exercise has never been significantly engaged in, except at least partially with the purpose of accruing the bodily and emotional benefits that are described (and if with any additional purposes, only social and/or entertainment ones) and
 * 2) its obliviousness to the current possibility, and the predominant historical pattern, of the benefits and hazards of physical exercise occurring predominantly or solely in the course of economic activities and for-keeps combat, and largely without conscious intent to do more than survive the day or year.
 * 1) chopping it up
 * 2) putting the pieces respectively into new articles called Effects of physical exercise and Physical training (which, BTW, should stop being a Rdr to Sports training),
 * 3) starting a stub Physical exercise incidental to work, and
 * 4) establishing lks among them that provide their readers with occasion to associate, by following lks, the pieces that are presently juxtaposed within the current accompanying article.

Sources for the first paragraph poor and lacking
Could anyone please add some extra sources to the first paragraph, the one that has an url in the citation ( http://content.nejm.org/cgi/content/full/343/1/16 ) does not establish any good relationship for physical exercise and lower rates of "diseases of affluence" that can be called anything better than just plain poor.

The study also doesn't supply much data that is different from their main variables, shown in the tables accompanying the paper, it acknowledges this by mentioning the effects nutrients might have on their results. It mentions that the variables they're studying have influence on each other, but doesn't mention that this influence is major as they're categorizing their control group by risk.

The second source doesn't have an url to it, so I can't even say anything about that content.

Major claims are unsourced, to quote "It also improves mental health and helps prevent depression. Childhood obesity is a growing global concern and physical exercise may help decrease the effects of childhood obesity in developed countries."

"weight loss or maintenance" (maintenance should be reworded as it implies that without exercise your body is unmaintained without defining the amount of exercise that is needed for "maintenance") is dubious as best, as I've read somewhere that the weight loss disappears over a time of months when the exercising and or diet stops and a high amount of people regain their weight. It's also common for people who burn more to eat more so the weight losing effect is minimal and the main effect is turning fat into muscle. There are no citations so I can't read up on the topic in scientific papers.

PLEASE increase the credibility by adding a lot more citations. —Preceding unsigned comment added by 82.101.205.224 (talk) 02:12, 4 June 2009 (UTC)

What is impact?
Could someone add some content about impact? For example, I've heard of a low-impact exercise, but don't know what that means. Does it mean it's easier than other exercises? Or maybe it refers to physical impacts on your joints, such as the way running can be hard on the knees. Orthografer (talk) 01:15, 11 July 2009 (UTC)
 * It usually refers to the latter kind of impact, as in hammering. Excellent topic for addition to the article. Hertz1888 (talk) 01:41, 11 July 2009 (UTC)

Exercise and brain function
The section about exercise and brain function is very clearly written, however the conclusion of some studies are even more direct than what is said in the section. Some studies conclude directly "Physical exercise is beneficial to cognition." Some studies even found correlations of exercising with IQ, learning, and memory. I think this could be more clearly stated. A short summary of two recent review articles can be found at this blog post. Oh, and I don't see any obvious reason why the section should not be part of the section on benefits. I'll put it there as subsection. Ben T/C 20:05, 8 August 2009 (UTC)

A prática regular de atividade física sempre esteve ligada à imagem de pessoas saudáveis. Antigamente, existiam duas idéias que tentavam explicar a associação entre o exercício e a saúde: a primeira defendia que alguns indivíduos apresentavam uma predisposição genética á prática de exercício físico, já que possuíam boa saúde, vigor físico e disposição mental; a outra proposta dizia que a atividade física, na verdade, representava um estímulo ambiental responsável pela ausência de doenças, saúde mental e boa aptidão física.

Reduction of cortisol
The claim that physical exercise reduces cortisol levels is at least misleading:

- directly after the exercise higher cortisol levels are observed

- certain kinds of exercise may lead to decreased cortisol levels in the long term but research seems to be inconclusive (some studies report little or no effect)

Sup. Citation number 19 is a crap study and the statement on the main page(which I changed to the best of my ability) was false. The reason the study is wrong is because it states nothing about the subjects diet, which is the primary factor in muscle growth when it comes to resistance training. If there were men in the study that were a)not castrated, and b) eating a calorie surplus, then there's no way they wouldn't have gained such small amounts of size as the study would have us believe. The only genetic factor that would really stop someone from growing is having low testosterone. That is why women can't grow big muscles even if they wanted without external anabolics. —Preceding unsigned comment added by 75.143.105.16 (talk) 07:47, 29 November 2010 (UTC)

Effect of exercise on ageing?
What information is there on how regular exercise affects the rate at which the body ages? Does exercise slow down, speed up, or have no effect on ageing?

Some old or old-fashioned medical research articles use this term but it is now considered unacceptable (like 'negroes') in academic style guides (e.g. APA Guidelines on Reducing Bias). 'Female athletes' is acceptable though, as here it is used as an adjective. Alleycat812 (talk) 08:58, 8 April 2013 (UTC)

Physiology?
I'm a little surprised that this article has essentially no information about the physiology of exercise. For example, why does lifting weights make you stronger? Why does cardiovascular exercise improve heart function and change metabolism? These are the kinds of questions I'd expect to find answered in this article. People take "use it or lose it" for granted when it comes to muscles (including the heart) and I would like to see the article address the mechanisms by which using muscles equals improving muscles. —Preceding unsigned comment added by 72.227.129.47 (talk) 18:29, 13 February 2008 (UTC)

I concur with the above, and would like to add this section under physiology, so as to address recent advances in myokine research. Note that myokines were not mentioned in the original article, and I added a sentence with a link to the Wikipedia myokine page:

In a 2012 overview, Pedersen and Febbraio presented the following in an article abstract: "During the past decade, skeletal muscle has been identified as a secretory organ. Accordingly, we have suggested that cytokines and other peptides that are produced, expressed and released by muscle fibres and exert either autocrine, paracrine or endocrine effects should be classified as myokines. The finding that the muscle secretome consists of several hundred secreted peptides provides a conceptual basis and a whole new paradigm for understanding how muscles communicate with other organs, such as adipose tissue, liver, pancreas, bones and brain. However, some myokines exert their effects within the muscle itself. Thus, myostatin, LIF, IL-6 and IL-7 are involved in muscle hypertrophy and myogenesis, whereas BDNF and IL-6 are involved in AMPK-mediated fat oxidation. IL-6 also appears to have systemic effects on the liver, adipose tissue and the immune system, and mediates crosstalk between intestinal L cells and pancreatic islets. Other myokines include the osteogenic factors IGF-1 and FGF-2; FSTL-1, which improves the endothelial function of the vascular system; and the PGC-1alpha-dependent myokine irisin, which drives brown-fat-like development. Studies in the past few years suggest the existence of yet unidentified factors, secreted from muscle cells, which may influence cancer cell growth and pancreas function. Many proteins produced by skeletal muscle are dependent upon contraction; therefore, physical inactivity probably leads to an altered myokine response, which could provide a potential mechanism for the association between sedentary behaviour and many chronic diseases."

The authors concluded: "In summary, physical inactivity and muscle disuse lead to loss of muscle mass and accumulation of visceral adipose tissue and consequently to the activation of a network of inflammatory pathways, which promote development of insulin resistance, atherosclerosis, neurodegeneration and tumour growth and, thereby, promote the development of a cluster of chronic diseases. By contrast, the finding that muscles produce and release myokines provides a molecular basis for understanding how physical activity could protect against premature mortality.... Given that muscle is the largest organ in the body, the identification of the muscle secretome could set a new agenda for the scientific community. To view skeletal muscle as a secretory organ provides a conceptual basis for understanding how muscles communicate with other organs such as adipose tissue, liver, pancreas, bone and brain. Physical inactivity or muscle disuse potentially leads to an altered or impaired myokine response and/or resistance to the effects of myokines, which explains why lack of physical activity increases the risk of a whole network of diseases, including cardiovascular diseases, T2DM (Type 2 Diabetes Mellitus), cancer and osteoporosis."

Types vs. categories
Types of exercise, categories of exercise... what's the difference? Two sections, some entries shared. It's confusing. Is there some way to combine these sections, or at least to clarify the difference between definitions (if there is one)? Hertz1888 (talk) 20:43, 26 May 2009 (UTC)
 * I merged all three of the sub-sections into one. I thought about deleting the third entirely as the source cited said "The vacuum of guiding authority has therefore necessitated that CrossFit’s directors provide their own definition of fitness" and "It will come as no surprise to most of you that our view of fitness is a contrarian view." While I doubt CrossFit is a WP:FRINGE proponent they did not seem to be advocating the consensus view of physical exercise. I ended up keeping and using the citation to include examples of exercise that did not fit into the three main types. --Marc Kupper&#124;talk 03:12, 23 March 2014 (UTC)

Proposed merge with Exercise as a treatment for depression
Do we need a separate page for this? Brainy J ~ ✿ ~ ( talk ) 00:03, 18 November 2013 (UTC) I am not sure if I am doing this the right way, but I wanted to add my comments regarding the "proposed merge of [Physical Exercise] with [Exercise as a Treatment for Depression]." If Brainy J's comment, "Do wse need a separate page for this?" is referring to commentary on whether this proposed merge should be approved, I would say yes.

I do not like the idea of "merging" the two, if I understand what is meant by the proposed merge, because I do not agree they should be merged. My reasoning is that although exercise can and has often been a helpful method of alleviating the symptoms of depression, one must take the following under serious consideration:
 * 1) 1.  Exercise has not been a successful method in treating depression for all.
 * 2) 2.  For those suffering Major Depression,, being able to exersise is almost as impossible as most endeavors that require effort, motivation, discipline, etc.
 * 3) 3.  Often, knowing that exercise would help alleviate depression, and being unable to do so impacts the depressed person negatively, worsening their symptoms.

My suggestion for your consideration is not that these two be merged, but that exercise be a sub-heading under a sub-heading for Depression, ex., Depression/Treatment Methods/Exercise, and vice-versa, ex., Exercise/Benefits/Helping Alleviate Depression.

As a new user, I ask your patience and guidance if I have not posted this properly, and would welcome any feedback. Renee Michelle Wenker (talk) 21:04, 14 December 2013 (UTC)
 * I completely agree with you. I don't know how to "formally" vote for this, however, since I am also new. JDiala (talk) 21:45, 27 December 2013 (UTC)

The Exercise as a treatment for depression article was deleted 29 December 2013. Articles for deletion/Exercise as a treatment for depression explains the reasoning. The Physical exercise section of this article was unchanged from 18 November 2013 to present indicating nothing was merged from the deleted article. --Marc Kupper&#124;talk 03:24, 23 March 2014 (UTC)

Basic definition of "Physical Exercise" vague and confusing
The article blurs the distinction between activities, sports, and exercise. I suggest that perhaps the definition as outlined by the American College of Sports Medicine, a preeminent authority in the fields of health, fitness and wellness, which defines physical activity and exercise as below may be more clear:

Physical Activity - any bodily movement produced by the contraction of skeletal muscle that significantly increases energy expenditure.

Exercise- subclass of physical activity Defined as planned, structured, and repetitive bodily movement done to improve or maintain one or more components of physical fitness.

Sport- subclass of physical activity Sport (or sports) is all forms of usually competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing entertainment to participants, and in some cases, spectators.

Health-Related and Skill-Related Components of Physical Fitness

Primary Components


 * Cardiorespiratory endurance: The ability of the circulatory and respiratory system to supply oxygen during sustained physical activity.
 * Body composition: The relative amounts of muscle, fat, bone, and other vital parts of the body.
 * Muscular strength: The ability of muscle to exert force.
 * Muscular endurance: The ability of muscle to continue to perform without fatigue.
 * Flexibility: The range of motion available at a joint.

Secondary Components
 * Agility: The ability to change the position of the body in space with speed and accuracy.
 * Coordination: The ability to use the senses, such as sight and hearing, together with body parts in performing tasks smoothly and accurately.
 * Balance: The maintenance of equilibrium while stationary or moving.
 * Power: The ability or rate at which one can perform work.
 * Reaction time: The time elapsed between stimulation and the beginning of the reaction to it.
 * Speed: The ability to perform a movement within a short period of time.

Defined in this way, the following would be physical activities unless it is done in an organized and competitive fashion, in which case it would become a sport: bicycling, mountain biking, swimming, skiing, cross country skiing, water skiing, swimming, diving, kayaking, rowing, tennis, etc., even weightlifting.

However, if one is engaged in training (with weights, jogging, with an stationery bicycle or a treadmill, swimming, etc. in a structured manner primarily to improve one of the 5 primary components, i.e. cardiovascular endurance, lean body mass, muscular strength or endurance, or flexibility) then one is exercising.

Basically, if one is doing something physical for fun it's an activity which might be further categorized as an exercise if one is using the activity to improve one of the 5 primary components of health and fitness. Or it may be a sport if it has rules and structure as to how it should be done.

 * One concern with this level of detail is dealing with WP:COPYVIO issues. For example, I grabbed "planned, structured, and repetitive" from the proposed text and found it here where we also learn it's one person's personal opinion and is copyright material.


 * Earlier today I merged three sub-sections of the Classification section of this article. The article had listed three similar/overlapping classifications with each based on a different source. I ended up using a United States government publication as the main source as it was public domain material. We can use their wording directly when applicable.


 * That said, the separation into "Physical Activity", "Exercise", and "Sport" is a good idea. I was unable to find a source for this on www.acsm.org and am wondering if it's a significant part of their platform. Rather than stating those words in this article it seems we could just keep in mind that the focus of this article is "Exercise" and not "Sport" --Marc Kupper&#124;talk 04:39, 23 March 2014 (UTC)

Addition
Hi, I would like to add to the subheading =Cancer=. I would like to add the 5 proposed host related mechanisms for the benefits of exercise on cancer: Metabolic hormones, sex-steroid hormone, immune surveillance, inflammation, and oxidation status. I would also like to add the possibility of p27 tumor suppressor involved in exercise benefits for cancer, the possibility of exercise as adjunct therapy for specific cancer types, that most studies that support the benefits of exercise are from breast and colorectal cancer, and the need for more consistent methods between studies to determine specific dosage of exercise as adjunct therapy. I was also like to add under =Health effects= "after statistical adjustment for physical activity, sedentary time was independently greater risk for all-cause mortality, cardiovascular disease incidence or mortality, cancer incidence or mortality (breast, colon, colorectal, endometrial, and epithelial ovarian), and type 2 diabetes in adults. However, the deleterious outcome effects associated with sedentary time generally decreased in magnitude among persons who participated in higher levels of physical activity compared with lower levels" This study suggest that meeting the recommend daily recommendation of exercise is not enough, if people are highly sedentary throughout the remainder of their waking hours. — Preceding unsigned comment added by Edward Tong (talk • contribs) 14:32, 5 February 2015 (UTC)

In extreme instances, over-exercising induces serious performance loss. Unaccustomed overexertion of muscles leads to rhabdomyolysis (damage to muscle) most often seen in new army recruits. Another danger is overtraining, in which the intensity or volume of training exceeds the body's capacity to recover between bouts.

Physical activity and Depression
Hi everyone. In the section discussing the potential benefits of physical activity (PA) on depression, I would argue that some of the references do not conclude the same thing as the wiki-article suggests. Of course there is a weak to moderate effect of exercise on depressive symptoms or depression, but most studies (including Cooney et al., 2013, which is cited here) are based on low methodological quality. For example Cooney et al., found that after including only studies of high methodological quality the effect sizes become much weaker (and non-significant). According to the conclusion of the authors: " However, it is not clear if research actually shows that exercise is an effective treatment for depression." so to say that PA definitely has an anti-depressogenic effect is misleading. Of course including only high methodological studies reduces the sample size (so the lowering of the effect size could be due to smaller samples) but I would again argue that this is not always the case. If the effect of PA on depression is robust, then the effect size should only reduce slightly when higher quality studies are included, but in some meta-analyses this effect is not significant anymore. Also an older meta-analysis (Mead et al., 2009) concludes that higher quality studies are needed before claiming that PA is beneficial in treating or preventing depression. — Preceding unsigned comment added by 145.15.244.116 (talk) 14:12, 5 March 2015 (UTC) In any event, if you know of any systematic analysis published within the past 2 years (like these 4 systematic reviews and the 2 additional corroborating 2014 reviews - and  - from Talk:Neurobiological effects of physical exercise that I didn't feel the need to cite) which is at odds with the current article text, I'll gladly include/cite it and indicate the disparity in the article. I can't use (Krohg) since it's not current and  (Rimer) is an older version of the Cochrane review cited in the article ; thus neither can be used to cite a medical statement in the article per WP:MEDRS.  Seppi  333  (Insert 2¢ &#124; Maintained) 18:15, 6 March 2015 (UTC)
 * Hmm you have a point... I sort of oversimplified that when I was summarizing Neurobiological effects of physical exercise (following WP:SUMMARYSTYLE). The reviews definitely indicate that exercise has antidepressant effects; the question is what "dose" (intensity/duration) and type (running, walking, swimming, weight-lifting, etc) yields optimal results. There's basically a consensus that any form of aerobic exercise is suitable; the antidepressant effect is also magnitude dependent, so typically higher intensities and longer duration (excluding anything insane) are correlated with better outcomes. I tried to clarify this in an edit I just made; anyone who is interested in knowing more should just go read the exercise neurobiology article though.  Seppi  333  (Insert 2¢ &#124; Maintained) 14:50, 5 March 2015 (UTC)
 * -->I am not sure this is the case though...there is some anti-depressant effect (which seems much stronger in older participants) for sure but consensus in my view is not really reached yet (see also Rimer et al., 2012 and Krogh et al., 2010-->can find u the references but don't have them at this point). The problem of low quality studies in combination with publication bias on the topic might make the effects of exercise a bit spurious. Even the causality of the relationship (if it is a direct or indirect causal link between PA and depressive symptoms) is disputed (for references i would say check Birkerland et al. 2009; Psychology of Sport and Exercise, 10(1), p.25-34; and De Moor et al. 2008; Archives of General Psychiatry, 65(8), 897). But would be happy with just toning down that section a bit. — Preceding unsigned comment added by 86.83.130.9 (talk) 17:03, 6 March 2015 (UTC)
 * I'm not sure what part of the current version of that paragraph you have issue with, as I don't see any issue with the current language. Every citation included unambiguously states that exercise has antidepressant effects; these papers are examining the efficacy of the antidepressant effect as a treatment for depression, not the existence of an antidepressant effect - this is why healthy individuals aren't included in the aggregated sample for meta-analysis in these reviews.

Comment
Physical activity releases the ‘feel good’ chemicals throughout the brain, called neurotransmitters, endorphins, and endocannabinoid’s. Neurotransmitters are responsible for sending “signals between nerve cells, called “neurons.” They can also affect mood, sleep, concentration, weight, and can cause adverse symptoms when they are out of balance” (Neurogistics par. 2). Stress, poor diet, drugs, and alcohol can cause neurotransmitters to be off balanced. Endorphins are distributed throughout the nervous system and interact with the “opiate receptors in the brain to reduce our perception of pain” (Stoppler Par 2). Endocannabinoids deal with appetite, pain sensation, mood, and memory. All three of these chemicals have a lot in common including the fact that they all get released during physical activity, bettering overall mental health. 2601:1:BF80:193:DD93:4AF3:E545:8FB7 (talk) 04:26, 23 April 2015 (UTC)

Physical activity
For some reason, Physical activity redirects to Physical exercise. Physical exercise is some kind of physical activity (mainly for the purpose of improving fitness), while the latter includes also activity as part of work or just as part of living-walking back from school, climbing stairs, hiking, dancing (or even having sex).

I think that there should be two articles-one about activity (health advantages, physiology-rise of heart pulse, muscles, sweating, ATP etc), and one about exercise (especially about training, preparation and cool down, sport injuries etc). Hummingbird (talk) 13:43, 20 May 2015 (UTC)

Sometimes the terms 'dynamic' and 'static' are used. 'Dynamic' exercises such as steady running, tend to produce a lowering of the diastolic blood pressure during exercise, due to the improved blood flow. Conversely, static exercise (such as weight-lifting) can cause the systolic pressure to rise significantly (during the exercise).
