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 pointsFenugreek plus creatine supplementation may be a new means of increasing creatine uptake.Creatine plus fenugreek seems to be just as effective as the classic creatine plus carbohydrate ingestion in terms of stimulating training adaptations.This is the first study to our knowledge that has combined fenugreek with creatine supplementation in conjunction with a resistance training program.
这项研究的目的是评估肌酸与葫芦巴提取物联合补充对力量和身体成分的影响。将 47 名接受阻力训练的男性根据体重分为三组，分别摄入 70 克葡萄糖安慰剂（PL）、5 克肌酸/70 克葡萄糖（CRD）或 3.5 克肌酸/900 毫克葫芦巴提取物（CRF），并参加为期 8 周的每周 4 次的阶段性阻力训练计划。在 0、4 和 8 周时，对受试者的身体成分、肌肉力量和耐力以及无氧能力进行测试。统计分析采用了独立的 3X3（条件[PL 与 CRD 与 CRF]x 时间[T1 与 T2 与 T3]）重复测量 ANOVA，所有标准变量的主效应（p ≤ 0.05）。任何身体成分测量均未观察到组间时间交互作用或主效应（p > 0.05）。CRF 组在 T2（p = 0.001）和 T3（p = 0.001）时的瘦体重显著增加。PL 组的卧推 1RM 在 T1-T3 时增加（p = 0.050），CRD 组在 T1-T2 时增加（p = 0.001），在 T3 时仍保持显著（p < 0.001）。CRF 组在 T1-T2 时（p < 0.001）卧推 1RM 显著增加，T2-T3 时也增加（p = 0.032）。PL、CRD 和 CRF 组的腿推 1RM 在所有时间点均显著增加（p < 0.05）。任何性能变量和血清临床安全概况均未观察到组间或组内的其他变化（p > 0.05）。总之，肌酸加葫芦巴提取物补充剂对上半身力量和身体成分的影响与 5 克肌酸与 70 克葡萄糖的组合一样有效。因此，在肌酸补充剂中使用葫芦巴可能是一种增加肌酸吸收的有效方法，同时消除了对大量简单碳水化合物的需求。关键点葫芦巴加肌酸补充剂可能是增加肌酸吸收的新方法。就刺激训练适应而言，肌酸加葫芦巴似乎与经典的肌酸加碳水化合物摄入一样有效。这是我们所知的首次将葫芦巴与肌酸补充剂联合使用并结合阻力训练计划的研究。
