|Table 1: Within and between group hormonal changes from baseline (T1) through week 8 (T3)|
It is all the more remarkable that the intervention produced significant increases in upper- and lower-body strength and body composition in the subjects, who took part in a supervised 4-day per week periodized resistance-training program split into two upper and two lower extremity workouts per week for a total of 8-weeks:
Significant group x time interaction effects were observed among groups in changes in body fat (FEN: -2.3 +/- 1.4%BF; PL: -0.39 +/- 1.6 %BF, p < 0.001), leg press 1-RM (FEN: 84.6 +/- 36.2 kg; PL: 48 +/- 29.5 kg, p < 0.001), and bench press 1-RM (FEN: 9.1 +/- 6.9 kg; PL: 4.3 +/-5.6 kg, p = 0.01). No significant interactions was observed among groups for Wingate power analysis (p = 0.95) or muscular endurance on bench press (p = 0.87) or leg press (p = 0.61). In addition, there were no changes among groups in any clinical safety data including lipid panel, liver function, kidney function, and/or CBC panel (p > 0.05).Obviously, the ergogenic effects of fenugreek are not mediated by hormonal changes. Also, the scientists refrain from any speculation which leaves us without answer to the question for the underlying mechanism of action.
