Heinecke, ML, Mauldin, ML, Hunter, ML, Mann, JB, and Mayhew, JL. Relationship of barbell and dumbbell repetitions with one repetition maximum bench press in college football players. J Strength Cond Res 35(2S): S66-S71, 2021-Dumbbell training to augment barbell training is gaining popularity. However, information is lacking that details the compatibility of strength and endurance between dumbbell and barbell performances in the same exercise. Therefore, the purposes of this study were to compare the similarity of muscular endurance performance between dumbbell and barbell exercises and to assess the accuracy of predicting one repetition maximum (1RM) barbell bench press from barbell and dumbbell repetitions to fatigue (RTF). College football players (n = 40) performed 1RM barbell bench press and RTF with a 90.9-kg barbell. On separate days, unilateral (45.5 kg) and bilateral dumbbell (90.9 kg) RTF were performed. Barbell RTF (13.8 ± 9.2) were significantly greater (effect size [ES] = 0.14) than bilateral dumbbell RTF (12.5 ± 9.5) but highly correlated (r = 0.96). Unilateral dumbbell RTF were significantly greater (ES = 0.13) for dominant hand (10.8 ± 10.1) than nondominant hand (9.5 ± 9.7) but highly correlated (r = 0.97). Prediction of 1RM barbell bench press was equally effective using a constant weight barbell (r = 0.90) or equivalent weight bilateral dumbbells (r = 0.87) with total errors of 7.3 and 8.2%, respectively. Barbell and dumbbell repetitions with equivalent weights place a similar demand on the upper-body musculature for training and testing purposes in football athletes.
海涅克、莫尔丁、亨特、曼恩和梅休。大学橄榄球运动员中杠铃和哑铃重复次数与 1 次重复最大卧推的关系。J 力量与调节研究 35(增刊):S66-S71,2021-哑铃训练作为杠铃训练的补充正变得越来越流行。然而,缺乏关于同一运动中哑铃和杠铃表现的力量和耐力之间兼容性的信息。因此,本研究的目的是比较哑铃和杠铃练习的肌肉耐力表现的相似性,并评估从杠铃和哑铃重复次数预测 1 次重复最大(1RM)杠铃卧推的准确性,直到疲劳(RTF)。大学橄榄球运动员(n=40)进行了 1RM 杠铃卧推和 90.9 公斤杠铃的 RTF。在单独的日子里,进行了单侧(45.5 公斤)和双侧哑铃(90.9 公斤)RTF。杠铃 RTF(13.8±9.2)显著大于(效应量[ES] = 0.14)双侧哑铃 RTF(12.5±9.5),但高度相关(r=0.96)。对于惯用手(10.8±10.1),单侧哑铃 RTF 明显大于非惯用手(9.5±9.7)(ES=0.13),但高度相关(r=0.97)。使用恒定重量杠铃(r=0.90)或等效重量双侧哑铃(r=0.87)同样可以有效地预测 1RM 杠铃卧推,总误差分别为 7.3%和 8.2%。对于足球运动员的训练和测试目的,具有等效重量的杠铃和哑铃重复次数对上半身肌肉施加相似的需求。
