Table 2 Resting values of select biochemical markers in elite gymnast (EG) and physically active man (PAM)

Fig. 1 The relative mean and peak power of anaerobic exercise in elite gymnast (EG) and physically active man (PAM) depending on vitamin D3 levels. White bars with stripes, 25(OH)D₃ levels below 22.50 ng/ml; white bars, 25(OH)D₃ levels above 22.50 ng/ml; grey bars with stripes, 24,25(OH)₂D₃ levels below 1.27 ng/ml; grey bars, 24,25(OH)₂D₃ levels above 1.27 ng/ml; LBT, lower body test; UBT, upper body test

Fig. 2 Changes in the bone turnover marker levels after Wingate anaerobic test (WAnT) in elite gymnast (EG) and physically active man (PAM) depending on the vitamin D3 levels. CTX, C-terminal telopeptide of type I collagen; PINP, N-terminal propeptide of type I collagen; a and b Lower body Wingate testing; c and d Upper body Wingate testing; I, changes in the peripheral blood 5 min post WAnT; II, changes in the peripheral blood 30 min post WAnT; white bars with stripes, 25(OH)D₃ levels below 22.50 ng/ml; white bars, 25(OH)D₃ levels above 22.50 ng/ml; grey bars with stripes, 24,25(OH)₂D₃ levels below 1.27 ng/ml; grey bars, 24,25(OH)₂D₃ levels above 1.27 ng/ml
