Physiologists Monitored Metabolite Concentrations Generated During Exercise in Three Groups

Multiple Choice

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?

A) Exercise was beneficial to all groups, but those benefits concluded immediately upon cessation of the exercise; to be significantly beneficial, the duration of exercise must be lengthened.
B) The metabolic responsiveness of unfit individuals was extremely low; unfit individuals are unlikely to experience benefits from exercise for at least 30 days after starting an exercise program.
C) 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.
D) Metabolites extracted from the blood of unfit individuals was shown to suppress the level of metabolism of cells growing in tissue culture.
