|---|---|---|---|---|
| Nonathletes n = 10 | 1st day of camp | 14th day of camp | 1st day of camp | |
| C [nmol/L] | 168 ± 52 | 691 ± 70 | 784 ± 86* | p < .001 |
| fT [nmol/L] | 7.16 ± 1.10 | 19.92 ± 1.72 | 13.32 ± 1.68** | p < .001 |
| hGH [pg/ml] | 60 ± 11 | 151 ± 30 | 170 ± 32 | p < .001 |
| IGF-I [ng/mL] | 85 ± 13 | 91 ± 14 | 75 ± 11** | p > .05 |
| IGFBP-3 [ng/mL] | 2645 ± 153 | 2820 ± 197 | 2532 ± 203# | p < .05 |
Note. C = cortisol; fT = free testosterone; hGH = human growth hormone; IGF-I = insulin-like growth factor I; IGFBP-3 = insulin-like growth factor binding protein 3.
