| ABSTRACT | |||
| The purpose of this study was to evaluate the effects of combined
creatine and fenugreek extract supplementation on strength and body composition.
Forty- seven resistance trained men were matched according to body weight
to ingest either 70 g of a dextrose placebo (PL), 5 g creatine/70 g of dextrose
(CRD) or 3.5 g creatine/900 mg fenugreek extract (CRF) and participate in
a 4-d/wk periodized resistance-training program for 8-weeks. At 0, 4, and
8-weeks, subjects were tested on body composition, muscular strength and
endurance, and anaerobic capacity. Statistical analyses utilized a separate
3X3 (condition [PL vs. CRD vs. CRF] x time [T1 vs. T2 vs. T3]) ANOVAs with
repeated measures for all criterion variables (p < 0.05). No group x
time interaction effects or main effects (p > 0.05) were observed for
any measures of body composition. CRF group showed significant increases
in lean mass at T2 (p = 0.001) and T3 (p = 0.001). Bench press 1RM increased
in PL group (p = 0.050) from T1-T3 and in CRD from T1-T2 (p = 0. 001) while
remaining significant at T3 (p < 0.001). CRF group showed a significant
increase in bench press 1RM from T1-T2 (p < 0.001), and also increased
from T2-T3 (p = 0.032). Leg press 1RM significantly increased at all time
points for PL, CRD, and CRF groups (p < 0.05). No additional between
or within group changes were observed for any performance variables and
serum clinical safety profiles (p > 0.05). In conclusion, creatine plus
fenugreek extract supplementation had a significant impact on upper body
strength and body composition as effectively as the combination of 5g of
creatine with 70g of dextrose. Thus, the use of fenugreek with creatine
supplementation may be an effective means for enhancing creatine uptake
while eliminating the need for excessive amounts of simple carbohydrates. Key words: Fenugreek, creatine, supplementation, performance adaptations. |
