Section 1: Exercise Science

A strength coach records hydration markers for three athletes before and after a training session. Based on the provided data, which athlete demonstrated the most severe ACUTE dehydration resulting directly from the training session?

Athlete	Pre-Session USG	Body Mass Change
Athlete A	1.008	-0.5%
Athlete B	1.026	-0.2%
Athlete C	1.010	-3.1%

Acute dehydration is best measured by body mass loss during exercise. Athlete C lost 3.1% body mass, significantly exceeding the 2% threshold for performance impairment. Although Athlete B began the session hypohydrated (high USG), their acute loss was minimal. USG reflects chronic hydration, whereas weight change measures acute fluid loss.
