press and chin-up were used to assess upper-body strength and the squat to test lower-body strength. The 1RM strength-testing protocols were conducted in accordance to the Australian National Protocols for the Assessment of Strength and Power. 18 All players performed the 1RM squat test first, followed

and medium external loads (from 0−20 kg), while researchers emphasized proper technique. During the second session, all 52 subjects performed a strength test with increasing loads up to 1RM for individual determination of the full load–velocity relationship. Finally, in the third session, the subjects

25(OH)D concentration in high-cortisol subjects. Corroborating our first hypothesis, no relationships between serum 25(OH)D and exercise performance were identified during power and strength testing. The lack of significant associations is consistent with cross-sectional studies on ice hockey players
