CSCS Practice Quesiton #14
A strength coach designs a repeated sprint protocol consisting of 6 × 6-second maximal sprints with 25 seconds of passive recovery between efforts. During the final two sprints, athletes exhibit a measurable decline in peak power output despite maximal effort.
Which physiological factor MOST directly explains the decline in power output?
A. Reduced calcium release from the sarcoplasmic reticulum limiting cross-bridge formation
B. Decreased motor unit recruitment caused by central nervous system inhibition
C. Incomplete phosphocreatine resynthesis due to insufficient oxidative recovery time
Answer in the poll, then explain your rationale below in the comments! I'll follow up with my breakdown of the question after enough people have responded.
From Chapter 3: Bioenergetics of Exercise and Training
A. Reduced calcium release from the sarcoplasmic reticulum limiting cross-bridge formation
B. Decreased motor unit recruitment caused by central nervous system inhibition
C. Incomplete phosphocreatine resynthesis due to insufficient oxidative recovery time
