Document Summary
Chapter 9 designing weight management & body composition programs. Peripheral edema (not enough nutrients, protein are important malnutrition) Reproductive disorders (lack of menstrual period for long periods of time) Gynoid obesity (mostly women) lower-body obesity. pear-shaped. more typical of females. some men. Cancers: colon, prostate, ovary, breast, endometrium, cervix, esophagus, gallbladder. Android obesity (mostly men) upper-body obesity. apple-shaped. more typical of males. some women. Causes: physiological factors , developmental factors, genetic factors, lifestyle factors, psychosocial factors. Direct calorimetry (16040$): used to measure the energy yield and calories equivalent of various foods. Indirect calorimetry ($): is used to measure energy expenditure during basal resting or activity states. Energy or caloric need: fu(cid:374)(cid:272)tio(cid:374) of a(cid:374) i(cid:374)di(cid:448)idual"s (cid:373)eta(cid:271)oli(cid:272) (cid:396)ate a(cid:374)d ph(cid:455)si(cid:272)al a(cid:272)ti(cid:448)it(cid:455) le(cid:448)el. Basal metabolic rate (bmr: measure of minimal amount of energy (kcal) needed to maintain basic & essential physiological functions such as breathing, blood circulation & temperature regulation, varies according to age, gender, body size/composition.
