Document Summary
Chapter 7 measuring and evaluating human energy-generating capacities pa. Concepts of individual differences and specificity help explain differences in capacity for anaerobic and aerobic power. Individual differences refer to real (true) differences among individuals: specificity: systematic training highly specific for neurologic, physiologic, and metabolic responses. Three systems of energy transfer and percentage use of their total capacity during all=out pa of different durations: short term energy system, long term energy system. Physiologic and biochemical measures include: size of intramuscular atp-pc pool, most direct estimate and correlates highly with performance assessments, atp and pcr depletion rates in all-out, brief duration activity. Max tests for 1 to 10 sec reflect energy transfer of immediate energy system. Jumping power test: sprint running or cycling, shuttle runs, arm cranking, simulated stair climbing, rowing, skiing. 1 foot-lb (ft-lb) = 0. 13825 kilogram meters (kg m) (kg-m) 1 kg-m = 7. 233 ft-lb = 9. 8066 joules.
