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（BFR）与低负荷抗阻训练相结合已被证明能产生与高负荷训练相似的肌肉肥大效果。然而，并非所有研究都发现BFR有效，这可能是由于方法上的差异。目前尚不清楚尺寸相似（5厘米）但材料不同（尼龙与弹性材料）的袖带之间是否存在差异。目的是确定窄弹性袖带和窄尼龙袖带在疲劳重复次数、主观用力感觉评分（RPE）以及不适感方面是否存在差异。16名男性和女性采用随机交叉设计，使用近端大腿处施加的弹性或尼龙限制袖带，完成了三组BFR伸膝运动。窄弹性袖带和窄尼龙袖带在疲劳重复次数（血流指标）或主观感觉评分方面没有差异。该数据表明，在抗阻运动中，相同宽度的弹性或尼龙袖带在相同压力下应能产生相似程度的BFR。
