Document Summary
Five components of health-related fitness: cardiorespiratory fitness most imp, muscular strength, muscular endurance, flexibility, body composition. Cardiorespiratory activities benefits: reduced risk obesity, diabetes, heart disease and cancer and lowered cholesterol and blood pressure/increasing athletic performance, sense of well being, immunity, decreasing daily fatigue/anxiety/depression. Cardiorespiratory = raise heart and respiration: circuit weight training, calisthenics, sports activity, cardiorespiratory provide oxygen, nutrients, and protective agents, respiratory pump = lungs (ventilator pump), bones (sternum, ribs, vertebrae), muscles (diaphragm, abdominals), breathing. Exercise: aerobic low intensity, rely oxygen to convert carbs and fats (walk, bike, ski, anaerobic high intensity, relies on carbs (sprints, shot put, fitte. Strength: ability of the neuromuscular system to exert force against external resistance: important for athletes, bending, turning, lifting, increase muscular strength with muscular and nervous system = neuromuscular system. Nerves connected to muscles: muscoske, letal = bones, muscles, ligaments, tendons, cartilage, joints. Skeletal muscles attached to bones by tendons: muscle contractions:
