Physiologists monitored metabolite concentrations generated during exercise in three groups of individuals (those with poor fitness, average fitness, and exceptional fitness); which statement best summarizes their findings?

Question

Quizplus · Accepted Answer

The statement best summarizing the findings of the study is that exercise produced an almost immediate positive metabolic effect in which the strength and duration was proportional to the fitness level; exercise was beneficial to all participants. This indicates that even individuals with poor fitness can benefit from exercise, but the level and duration of benefits may be less compared to those with better fitness. The study does not suggest that exercise benefits conclude immediately upon cessation or that unfit individuals are unlikely to experience benefits from exercise for at least 30 days after starting an exercise program. Additionally, the study does not show that metabolites extracted from the blood of unfit individuals suppress the level of metabolism of cells growing in tissue culture.
