Dunkin, JE and Phillips, SM. The effect of a carbohydrate mouth rinse on upper-body muscular strength and endurance. J Strength Cond Res 31(7): 1948-1953, 2017-Carbohydrate (CHO) mouth rinsing rapidly increases corticomotor output and maximal muscle force production, which could enhance muscular strength and endurance during resistance exercise. However, previous research has found no effect of CHO rinsing on muscular strength or endurance. The current study altered the CHO rinse composition and frequency and the muscular endurance test to further investigate the effects of a CHO mouth rinse on upper-body muscular strength and endurance. Twelve recreationally resistance-trained men (mean ± SD age 22 ± 1 year, height 179.2 ± 1.8 cm, body mass 80.9 ± 6.1 kg) completed a bench press protocol (1 repetition maximum [RM] test followed by repetitions to failure at 40% of 1RM) on 3 occasions. Subjects rinsed 25 ml of an 18% CHO solution or a placebo for 10 seconds before 1RM and repetitions to failure and completed a no-rinse control condition. Felt arousal (FA) was measured before and after each rinse, heart rate (HR) was measured before and after both exercise protocols, and rating of perceived exertion (RPE) was recorded after repetitions to failure. Rinsing did not influence 1RM (p = 0.680, (Equation is included in full-text article.)= 0.03), repetitions to failure (p = 0.677, (Equation is included in full-text article.)= 0.04), or exercise volume (load × reps; p = 0.600, (Equation is included in full-text article.)= 0.05). There were no significant treatment effects on heart rate (p = 0.677, (Equation is included in full-text article.)= 0.04), FA (p = 0.674, (Equation is included in full-text article.)= 0.04) or rating of perceived exertion (p = 0.604, (Equation is included in full-text article.)= 0.05). A CHO mouth rinse does not improve upper-body muscular strength or endurance.
邓金，JE和菲利普斯，SM。碳水化合物漱口对上身肌肉力量和耐力的影响。《力量与体能研究杂志》31(7): 1948 - 1953，2017年 - 碳水化合物（CHO）漱口能迅速增加皮质运动输出和最大肌肉力量产生，这可能会增强抗阻运动期间的肌肉力量和耐力。然而，先前的研究未发现CHO漱口对肌肉力量或耐力有影响。当前研究改变了CHO漱口液的成分和频率以及肌肉耐力测试，以进一步探究CHO漱口对上身肌肉力量和耐力的影响。12名接受过休闲抗阻训练的男性（平均±标准差年龄22±1岁，身高179.2±1.8厘米，体重80.9±6.1千克）分3次完成了卧推方案（1次重复最大值[RM]测试，随后以1RM的40%进行重复至力竭测试）。受试者在进行1RM测试和重复至力竭前，用25毫升18%的CHO溶液或安慰剂漱口10秒，并完成无漱口对照条件。在每次漱口前后测量感觉唤醒（FA），在两个运动方案前后测量心率（HR），在重复至力竭后记录主观用力感觉等级（RPE）。漱口对1RM（p = 0.680，（公式包含在全文中）= 0.03）、重复至力竭次数（p = 0.677，（公式包含在全文中）= 0.04）或运动总量（负荷×重复次数；p = 0.600，（公式包含在全文中）= 0.05）均无影响。对心率（p = 0.677，（公式包含在全文中）= 0.04）、FA（p = 0.674，（公式包含在全文中）= 0.04）或主观用力感觉等级（p = 0.604，（公式包含在全文中）= 0.05）均无显著治疗效果。碳水化合物漱口并不能提高上身肌肉力量或耐力。
