Document Summary
The physical fitness of children has been assessed through a variety of laboratory and field-based measures, and may be improved through the application of appropriate training techniques. Physical fitness is a positive state of well-being influenced by regular physical activity, genetic make-up, and nutritional adequacy. Muscular strength and muscular endurance: muscle. Body composition: fat mass and lean mass. Definition: numerous repetition of a stressful activity circulatory and respiratory systems, oxygen = energy. April 3, 2017: females consume 70% less because of the size. Measures of physical activity: activity self-reports, heart rate monitor, accelerometers. Muscular strength: ability of the body to exert force, overload. Muscular endurance: ability of a muscle or a group of muscles to perform work repeatedly against moderate resistance, need to have muscular strength for muscular endurance. Not continuous, there is a break: isokinetic. Measures of strength/endurance: laboratory (strength): dynamometers. Measures different types of strengths: field (endurance): sit-ups, push-ups, pull-ups.
