A swim coach is monitoring the physiological responses of athletes during different training sessions. The graph shows lactate levels of two athletes during their respective training sessions.

Based on the lactate response to training shown, which of the following statements is most accurate?

Athlete A is likely performing high-intensity interval training
Athlete B is likely performing low-intensity aerobic training
Both athletes are performing the same training at different intensities
Athlete A is likely performing moderate steady-state aerobic training

\(D\)

Show Worked Solution

D is correct: Athlete A’s lactate levels show a gradual, moderate increase typical of steady-state aerobic training below the lactate threshold.

Other Options:

A is incorrect: High-intensity interval training would produce higher, fluctuating lactate levels than shown for Athlete A.
B is incorrect: Athlete B’s steep lactate increase indicates high-intensity training, not low-intensity aerobic training.
C is incorrect: The lactate patterns suggest different types of training, not the same training at different intensities.
