Abstract

Blood flow restriction (BFR) combined with low load resistance training has been shown to result in muscle hypertrophy similar to that observed with higher loads. However, not all studies have found BFR efficacious, possibly due to methodological differences. It is presently unclear whether there are differences between cuffs of similar size (5 cm) but different material (nylon vs. elastic). The purpose was to determine if there are differences in repetitions to fatigue and perceptual ratings of exertion (RPE) and discomfort between narrow elastic and narrow nylon cuffs. Sixteen males and females completed three sets of BFR knee extension exercise in a randomized cross-over design using either elastic or nylon restrictive cuffs applied at the proximal thigh. There were no differences in repetitions to fatigue (marker of blood flow) or perceptual ratings between narrow elastic and narrow nylon cuffs. This data suggests that either elastic or nylon cuffs of the same width should cause similar degrees of BFR at the same pressure during resistance exercise.

血流限制:袖带类型对抗阻运动疲劳和知觉反应的影响。
血流量限制(BFR)结合低负荷阻力训练已被证明会导致肌肉肥大,与高负荷时观察到的结果相似。然而,并不是所有的研究都发现BFR有效,可能是由于方法上的差异。目前尚不清楚相似尺寸(5厘米)但不同材质(尼龙与弹性)的袖口之间是否存在差异。目的是确定在窄弹性和窄尼龙袖口之间是否存在重复疲劳和知觉等级(RPE)和不适的差异。16名男性和女性在随机交叉设计中完成了三组BFR膝关节伸展运动,在大腿近端使用弹性或尼龙限制袖带。窄弹性和窄尼龙袖口之间在疲劳(血液流动的标志)或知觉评分上的重复没有差异。这一数据表明,在阻力运动中,相同宽度的弹性或尼龙袖口在相同的压力下都会造成相似程度的BFR。
