Heather's Comments

 * March 4- Good start!  These headings should help with organization.  Please add a references heading with any new sources you found, in MLA format.  Also note in your work log (or perhaps by bolding it) what you changed in the text of the article.  Make all changes here in the sandbox and not yet on the main page.  Thanks!

Feb 27Th - focused on first paragraph. adding to it, clarifying, making easy to read and all inclusive and not directed to just athletes. 1hour

Feb 28th - Read the rest of article, found scholar articles confirming what was written and/or editing and correcting statements. 2hours

Feb 29th - Correcting sandbox and edited paragraphs more and aded headings. 1 hour

march 10- Read heather comments, bolded all the text I edited, added to metabolic paragraph added a reference heading of my new reference I     found. 1 hour

'Anaerobic exercise - '''high intensity movements preformed in a short period of time. It can be used by athletes in sports to promote strength, endurance, speed and power; and are used by body builders to build workout intensity'''. Muscle energy systems trained using anaerobic exercise develop differently compared to aerobic exercise, leading to greater performance in short duration, high intensity activities, which last from mere seconds to up to about 2 minutes. During Anaerobic exercises your energy is drawn from a limited supply of stored muscle glycogen to support this short burst of intense activity since oxygen stores are not sufficient. Anaerobic exercises demand more intensity/energy than Aerobic exercises that require steady energy stores for endurance. '''Anaerobic means with "no oxygen".Anaerobic workouts have many benefits and can be more reasonable to do on a daily basis due to the time required and the expended energy in a short period of time. Anaerobic workouts can be preformed with body weight at home. There are many options for Anaerobic exercises .'''

Personal trainers '''may use anaerobic exercise to help their clients take steps to building endurance, and build muscle strength and power. Anaerobic exercises coupled with Aerobic exercises provide health benefits for those diagnosed with diabetes. '''

Metabolism[edit]
Anaerobic metabolism is a natural part of metabolic energy expenditure. Anaerobic exercises are intense which require Fast twitch muscle s (as compared to slow twitch muscle) operates using anaerobic metabolic systems, such that any recruitment of fast twitch muscle fibers leads to increased anaerobic energy expenditure. Intense exercise lasting upwards of about four minutes (e.g., a mile race) may still have a considerable anaerobic energy expenditure component. High-intensity interval training, although based on aerobic exercises like running, cycling and rowing, effectively becomes anaerobic when performed in excess of 90% maximum heart rate. Anaerobic energy expenditure is difficult to accurately quantify although there are some ways to estimate the anaerobic component to exercise are available they may be unreliable.

In contrast, aerobic exercise includes lower intensity activities performed for longer periods of time. Activities such as walking, long slow runs, rowing, and cycling require a great deal of oxygen to generate the energy needed for prolonged exercise (i.e., aerobic energy expenditure). In sports which require repeated short bursts of exercise however, the anaerobic system enables muscles to recover for the next burst. Therefore, training for overall heath or sports demands that both energy producing systems be developed in order to keep progressing in endurance and power.

The by-product of anaerobic glycolysis—lactate—has traditionally been thought to be detrimental to muscle function. However, this appears likely only when lactate levels are very high and acidosis is created. Elevated lactate levels are only one proven '''event of many changes that occur within and around muscle cells during intense exercise that can lead to fatigue.There are other acids that build up and may cause fatigue. Fatigue,''' that is muscle failure, is a complex subject. '''Many individuals do not reach muscle failure as they quit due to discomfort or mental stamina. Elevated muscle and blood lactate concentrations are a natural consequence of any physical exertion. The effectiveness of anaerobic activity can be improved through training. Anaerobic exercise while first being preformed raised lactate levels, studies in 61 individuals show that over time with continued exercise that lactate levels will decrease.'''

'''Anaerobic exercise as well as many other exercise increases basal metabolic rate (BMR). A study shows those who are wanting strength and power benefit much more from Anaerobic exercise than those who want to build their endurance. '''
