The term body composition refers to the percentage of body weight that is fat (% body fat) compared with total lean mass. Its measurement is based on the assumption that body weight can be divided into lean body weight and fat weight. Levels of subcutaneous body fat levels in the upper body (waist measurement) and lower body (hip measurement) are distributed differently by sex, age, body type, and activity level.
Exercise scientists generally consider the best indicator of cardiovascular fitness to be the body’s ability to take in and utilize oxygen. Maximal oxygen consumption may be defined as the maximal rate at which the body can take up, distribute, and use oxygen in the performance of large-muscle-mass exercise. When oxygen uptake can no longer increase despite the fact that work can continue at higher levels for a short time because of anaerobic power sources, the participant has reached a ...
Proper muscle balance, in which agonist and antagonist muscle pairs maintain appropriate ratios of strength, flexibility, and length to one another, is important for avoiding musculoskeletal injury. To move body segments, the muscles opposite those performing the movement (antagonist muscles) must lengthen sufficiently. Tight muscles, tendons, and ligaments limit lengthening of the antagonist muscles and thus reduce the range of movement of body segments.
Then the plantar surface of the foot and the medial lower leg engage the water, while the knee and hip extend, rotate, and adduct toward the glide position. The arm power phase starts from the glide position. ” Give the cue to start the stroke with the arms and finish with the legs: “Pull and breathe, kick and glide.
