Previous studies have demonstrated that ayurvedic ingredients exhibit ergogenic (performance enhancing) properties, however, no previous studies have examined the ergogenic potential of . The purpose of the present study was to examine the ergogenic efficacy of supplementation with 500 mg·d of during bench press training. Eighteen recreationally trained men (mean ± SD; age = 20.4 ± 0.5 yrs; height = 179.7 ± 1.5 cm; weight = 84.7 ± 5.7 kg) were randomly assigned either 500 mg·d of ( = 10) or placebo ( = 8). An overlapping sample of 10 participants were used to determine test-retest reliability. Pre- and post-training testing included bench press with one repetition maximum (1RM) and repetitions to failure at 70% of pre-training 1RM. The participants performed two sets of bench press to failure three times a week for eight weeks. Independent -tests, Analyses of covariance (ANCOVA), and regression analyses were used to analyze the dependent variables. The results demonstrated greater mean percentage (14.3 ± 7.7% vs. 7.8 ± 4.5%; = 0.048) and individual (80% vs. 50%) increases in 1RM, mean (17.5 ± 2.2 repetitions vs. 15.2 ± 2.2 repetitions; = 0.044) and individual (80% vs. 38%) increases in repetitions to failure, and a greater rate of increase in training loads for the Asparagus racemosus group than the placebo group. In conjunction with bench press training, supplementation with provided ergogenic benefits compared to placebo.
先前的研究表明，阿育吠陀成分具有促力（提高运动表现）特性，然而，以前没有研究考察过[具体成分未提及]的促力潜力。本研究的目的是检验在卧推训练期间补充500毫克·天的[具体成分未提及]的促力功效。18名进行休闲训练的男性（平均值±标准差；年龄 = 20.4 ± 0.5岁；身高 = 179.7 ± 1.5厘米；体重 = 84.7 ± 5.7千克）被随机分配服用500毫克·天的[具体成分未提及]（n = 10）或安慰剂（n = 8）。使用10名参与者的重叠样本确定重测信度。训练前和训练后的测试包括一次重复最大值（1RM）卧推以及在训练前1RM的70%强度下进行至力竭的重复次数测试。参与者每周进行三次两组卧推至力竭，共持续八周。使用独立t检验、协方差分析（ANCOVA）和回归分析来分析因变量。结果显示，1RM的平均百分比增幅更大（14.3 ± 7.7%对7.8 ± 4.5%；p = 0.048）以及个体增幅更大（80%对50%），至力竭重复次数的平均值增幅更大（17.5 ± 2.2次对15.2 ± 2.2次；p = 0.044）以及个体增幅更大（80%对38%），并且与安慰剂组相比，芦笋组的训练负荷增加率更高。与卧推训练相结合，补充[具体成分未提及]比安慰剂具有更多的促力益处。
