Figures & data

Table 1 Subject characteristics (values are mean ± SEM).

Figure 1 Cortisol, testosterone, lactate and growth hormone response to exercise after 10 days of oral treatment with 600 mg S-PS or placebo (pre-exercise phase -30 to 0 minutes, exercise phase: 0 to 15 minutes, recovery phase 16 to 80 minutes).

Table 2 Mean peak concentrations (mean ± SEM).

Figure 2 S-PS significantly decreased cortisol (35 ± 0%, p < 0.01) and increased testosterone (37 ± 5%, p = 0.02) AUC levels and testosterone to cortisol ratio (184 ± 5%, p = 0.02) in comparison to placebo.
