An athlete trains using different intensities across a session. Which energy system requires the LONGEST recovery period?

ATP-PCr system after a 10-second sprint
Glycolytic system after a 60-second effort
Aerobic system after a 10-minute effort
ATP-PCr and Glycolytic combined after a 20-second effort

\(B\)

Show Worked Solution

B is correct: A 60-second maximal glycolytic effort produces high lactate levels requiring extended recovery time for acid-base balance restoration and lactate removal.

Other Options:

A is incorrect: ATP-PCr recovers relatively quickly
C is incorrect: Aerobic system recovers during activity
D is incorrect: Combined systems don’t extend recovery time
