Bioelectrical Impedance - This test measures body composition. Using either a hand-held or at-home scale, a slight electrical signal is sent through either the hands or feet. Body fat percentage is estimated based on the speed in which the signal passes through body tissues. According to the American Council on Exercise (ACE) men with a body fat percentage of 14-17% and women with a body fat percentage of 21-24% are considered to be in the 'fitness' category.
Achieving resilience through physical fitness promotes a vast and complex range of health-related benefits. Individuals who keep up physical fitness levels generally regulate their distribution of body fat and stay away from obesity. Abdominal fat, specifically visceral fat, is most directly affected by engaging in aerobic exercise. Strength training has been known to increase the amount of muscle in the body, however, it can also reduce body fat. Sex steroid hormones, insulin, and an appropriate immune response are factors that mediate metabolism in relation to the abdominal fat. Therefore, physical fitness provides weight control through regulation of these bodily functions.
People who are physically fit are also healthier, are able to maintain their most optimum weight, and are also not prone to cardiac and other health problems. In order to maintain a relaxed state of mind, a person should be physically active. A person who is fit both physically and mentally is strong enough to face the ups and downs of life, and is not affected by drastic changes if they take place.
