Sample characterization in relation to body mass, axillar temperature, and urine specific density before and after protocols (N = 28).

Variables	Moment	Control protocol	Hydration protocol
Body mass (kg)	Initial	80.98 ± 12.71	80.98 ± 12.82
	Final	80.64 ± 12.70a	80.97 ± 12.80
Axillar temperature (°C)	Initial	35.20 ± 0.54	35.02 ± 0.74
	Final	34.90 ± 0.97	34.82 ± 0.98
