A female athlete who feels pressured to maintain a certain physique or body weight may exercise excessively and develop eating disorders to restrict calorie intake. Over-exercising increases the need for rest; her overall energy declines, causing her total body fat and estrogen levels to drop - a condition known as amenorrhea. [6]
Most forms of dance may be considered aerobic exercise, and as such can also reduce the risk of cardiovascular disease, help weight control, stress reduction, and bring about other benefits commonly associated with physical fitness. In addition, studies have demonstrated a considerable correlation between dancing and psychological well-being.
Athlete's heart is common in athletes who routinely exercise more than an hour a day, and occurs primarily in endurance athletes, though it can occasionally arise in heavy weight trainers. The condition is generally considered benign, but may occasionally hide a serious medical condition, or may even be mistaken for one. [4]
The heart will also need to beat faster to adequately oxygenate the body and maintain blood pressure. [10] It has been hypothesized that individuals who are at risk for cardiovascular disease may develop negative cardiovascular outcomes in the event that cool-downs are not completed following bouts of exercise. However, current clinical ...
Cardiovascular fitness is a component of physical fitness, which refers to a person's ability to deliver oxygen to the working muscles, including the heart.Cardiovascular fitness is improved by sustained physical activity (see also Endurance Training) and is affected by many physiological parameters, including cardiac output (determined by heart rate multiplied by stroke volume), vascular ...

Other studies have shown that exercise-based rehabilitation at a moderate intensity in heart failure patients improves cardiorespiratory fitness and increases both exercise endurance capacity and VO2max (12–31% increase). [15] More recent studies have examined the effects of high-intensity exercise on patients with heart failure.
