Physiology
Athletes involved in isotonic exercises have an increased mean left ventricular end-diastolic volume and are less likely to be depressed. Due to their strenuous physical activities, athletes are far more likely than the general population to visit massage salons and pay for services from massotherapists and masseurs. Athletes whose sport requires endurance more than strength usually have a lower calorie intake than other athletes.

"Athlete Genes"
While athleticism is largely influenced by environmental factors, it has been theorized that genetic expression may play a moderate role in an athlete's abilities as well. Exploring this claim, meta-analyses of studies regarding two specific genes, angiotensin-converting enzyme (ACE) gene and ACTN3, concluded that certain variations in expression may have a moderate effect on athletic performance; the former being more prevalent in endurance-based events and the latter in power-based events. It is important to note that further studies should be conducted to substantiate these findings on a greater scale. Other genetic polymorphisms may similarly be linked to performance, but again further analysis is required.
