Benefits of physical activity include- reduced cardiovascular disease, diabetes, cancer, obesity, depression, premature death. Improved cardiorespiratory endurance: reduced risk of heart disease, prevention of hypertension. Improved quantity/quality of life, mental health and stress management. Improves cardiorespiratory endurance- heart, lungs and blood vessels function efficiently. Aerobic power- volume of o2 consumed by muscles. Determining frequency, intensity and time: first increase frequency, then length, then intensity. Methods of providing resistance- body weight, fixed ((cid:373)ass does(cid:374)"t (cid:272)ha(cid:374)ge- 20lb weight), variable (fixes velocity, changes resistance) Traumatic injuries- sudden (prevention- proper footwear, protective equipment) Bmi (body mass index)- (weight in lbs/(height in inches2)) x 705. Assessment- dual-energy x-ray absorptiometry, hydrostatic weighing, skinfold measurements. Resting metabolic rate (rmr), basal metabolic rate (bmr) Rarely successful, contributes to developing eating disorders. Cut starchy carbs, instead of all carbs (cid:862)mira(cid:272)le(cid:863) diets- very low-calorie diets, can be dangerous (ketosis)
