Luebbers, PE, Witte, EV, and Oshel, JQ. Effects of practical blood flow restriction training on adolescent lower-body strength. J Strength Cond Res 33(10): 2674-2683, 2019-The purpose of this study was to examine the effects of a practical blood flow restriction (BFR) training program on lower-body strength of high school weightlifters. Twenty-five students were divided into 3 groups. For 6 weeks, each group completed the same resistance training program with the exception of the parallel back squat exercise (2 d·wk), which was different for each group. One group (HI) completed a traditional high-load (≥65% 1 repetition maximum [1RM]) back squat protocol with 3 sets of low repetitions (≤10). The LO group completed the squat exercise using a relatively light load (≤30% 1RM) for 1 set of 30 repetitions and 3 sets of 15 with 30 seconds of rest between sets. The LO + BFR group followed the same protocol as LO, but did so with blood flow restricted. One repetition maximum back squat tests were conducted before the start of the program and again on conclusion, the values of which were used as the dependent measure. A 3 × 2 (group × time) repeated-measures analysis of variance revealed a significant interaction (p = 0.043). Follow-up tests were conducted to explore the interaction. Paired-sample t-tests for each group indicated a significant increase in leg strength for the LO + BFR group (p = 0.005) but not for the HI (p = 0.142) or LO groups (p = 1.00). This suggests that a practical BFR training program may be effective in increasing 1RM squat performance of high school students.
吕伯斯、PE、威特、EV 和奥舍尔、JQ。实用血流限制训练对青少年下肢力量的影响。J 强能力研究 33(10)：2674-2683，2019-本研究的目的是检验一种实用血流限制（BFR）训练方案对高中举重运动员下肢力量的影响。25 名学生被分为 3 组。在 6 周内，每组都完成了相同的抗阻训练计划，但除了每组不同的平行深蹲练习（2 d·wk）。一组（HI）完成了传统的高负荷（≥65%1 重复最大[1RM]）深蹲方案，每组 3 次，重复次数≤10。LO 组以相对较轻的负荷（≤30%1RM）完成 1 组 30 次重复和 3 组 15 次重复，每组之间休息 30 秒。LO+BFR 组遵循与 LO 相同的方案，但采用血流限制。在计划开始前和结束后进行 1 次最大重复后深蹲测试，将测试值作为因变量。3×2（组×时间）重复测量方差分析显示存在显著的交互作用（p=0.043）。进行了后续测试以探索交互作用。每组的配对样本 t 检验表明，LO+BFR 组的腿部力量显著增加（p=0.005），而 HI（p=0.142）或 LO 组（p=1.00）则没有增加。这表明，实用的 BFR 训练方案可能有效提高高中生的 1RM 深蹲表现。
