In recent years Fenugreek has been touted as an ergogenic aid. The purpose of this study was to evaluate the effects of Fenugreek supplementation on strength and body composition. Methods 49 Resistance trained men were matched according to body weight and randomly assigned to ingest in a double blind manner capsules containing 500 mg of a placebo N 23 20 years 178 cm 85 kg 17 BF or Fenugreek N 26 21 years 178 6 cm 90 kg BF . Subjects participated 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. At 0 4 and 8-weeks subjects underwent hydrodensiometery body composition 1-RM strength muscle endurance and anaerobic capacity testing. Data were analyzed using repeated measures ANOVA and are presented as mean SD changes from baseline after 60days. Results No significant differences p between groups were noted for training volume. Significant group X time interaction effects were observed among groups in changes in body fat FEN BF PL BF p leg press 1-RM FEN kg PL 48 kg p and bench press 1-RM FEN kg PL kg p . No significant interactions was observed among groups for Wingate power analysis p or muscular endurance on bench press p or leg press p . In addition .
