KIN 369 Exercise Metabolism Questions with Complete Correct Answers | Grade A+

Recovery from exercise? Ans: Oxygen uptake remains elevated above rest into recovery; oxygen debt; excess postexercise oxygen consumption What is the "rapid" portion of O2 debt? Ans: Resynthesis of stored PC, replenishing muscle and blood O2 stores What is the "slow" portion of O2 debt? Ans: Elevated heart rate and breathing=increased energy need; elevated body temp=increased metabolic rate; elevated epinephrine and norepinephrine=increased metabolic rate; conversion of lactic acid to glucose VO2 kinetics in the upper reached of the moderate intensity domain are influenced by? Ans: The pre-transition metabolic rate Demand for mitochondrial ATP production rises in line with the reduction in? 2 Ans: Intracellular energy state What % of lactic acid is oxidized following exercise? Ans: 70% What % of lactic acid is converted to glucose following exercise? Ans: 20% What % of lactic acid is converted to amino acids following exercise? Ans: 10% Lactic acid is removed more rapidly when? Ans: With light exercise in recovery What are the factors contributing to EPOC? Ans: Elevated hormones, post-exercise elevation of HR and breathing, elevated body temperature, restoration of muscle and blood oxygen stores, lactate conversion to glucose, and resynthesis of PC in muscle What is the metabolic response in prolonged exercise
