Document Summary

Energy expenditure and macronutrient metabolism in physically active adults. Use the dri, mets, i(cid:374)te(cid:374)sit(cid:455), porta(cid:271)le de(cid:448)i(cid:272)es they all have limitations. The regular method proposed has some weaknesses too. Active vs very active depending on the intensity of the exercise, duration, etc. Evaluate intensity, frequency and duration of exercise and then to add this increment to the energy needed for normal daily activity. Lo(cid:449) a(cid:272)ti(cid:448)e (cid:448)s a(cid:272)ti(cid:448)e. this is what we want to determine. Should maintain appropriate weight and body composition while training for a sport. New concept of measurement from position paper: (cid:862)energy availability (cid:894)ea(cid:895): (cid:862)a(cid:373)ou(cid:374)t of energy available to the body to perform all other fu(cid:374)(cid:272)tio(cid:374)s after the (cid:272)ost of e(cid:454)er(cid:272)ise is su(cid:271)tra(cid:272)ted (cid:863) Will be covered in the eating disorder session. (later on during the course). Sometimes equations to estimate energy requirement add a physical activity (pa) factor (image no. What they assume by typical daily activity might differ from one person to another.
