Jumping power tests refinements are unjustified in this context because of the large booklet on exercise testing by Lange Andersen et al. What are the measurements of energy expenditure? Daily energy expenditure is composed of three major components: 1) resting metabolic rate (RMR); 2) the thermic effect of feeding (TEF); and 3) the thermic effect of activity (TEA).
