NFS284H1 Lecture Notes - Lean Body Mass, Phosphocreatine, Basal Metabolic Rate
Document Summary
Fitness the ability to perform routine physical activity without undue fatigue. Overload principle adaptation to stress during exercise the more you do, the more you are capable of doing. Cardiorespiratory endurance how long you can continue a task. Increased by aerobic exercise: heart rate, use of oxygen, resting heart rate, stroke volume, aerobic capacity for vo2 max. Maximum amount of oxygen consumed by tissue during. Increased by repeated resistance or strength training (e. g. , using muscles to move against a resisting force: muscle hypertrophy (note: loss of muscle = atrophy, bone density, osteoporosis. Flexibility range of motion stretching of ligaments and muscles. Body composition amount of lean body mass compared to body fat. Fitness leads to higher proportion of lean body mass. Regular exercise increases muscle increases resting energy metabolism (ree) or basal metabolic rate (bmr) Cardiovascular health: blood pressure, hdl cholesterol. Diabetes prevention and management: insulin sensitivity. Cancer risk: estrogen levels = risk of breast cancer, risk of colon cancer.
