Abstract

Background

Increasing inter-set rest interval during low-intensity exercise with blood flow restriction (LI-BFR) may exacerbate metabolic stress, potentially enhancing muscle strength and hypertrophy responses to LI-BFR. Contrarily, perceptual responses (rate of perceived exertion [RPE] and pain) might be further impaired under increased inter-set rest interval.

Objective

We compared the neuromuscular and perceptual responses to LI-BFR performed with short vs. long inter-set rest intervals.

Design

randomized within-subject design.

Method

Thirteen physically-active men (22 ± 6 y; 1.75 ± 0.06 m; 75.9 ± 13.8 kg) were submitted to unilateral LI-BFR (30% one-repetition maximum, 1-RM) in the incline leg press exercise with one leg resting 60s between sets (G60) and the other resting 120s (G120). The training protocol consisted of 15 reps/set, 3 sets/session, 4 sessions/week for 3 weeks, while training pressure was established as 80% of the arterial occlusion pressure. Cross-sectional area (CSA) from whole quadriceps femoris was measured through magnetic resonance imaging. CSA and 1-RM were assessed at baseline and after training. RPE and pain were evaluated immediately after each set during the initial, middle and last training sessions.

Result

Both G60 and G120 were similarly effective in increasing whole quadriceps CSA (+5.7 ± 3.0% and +5.4 ± 2.5%, respectively; both P < 0.0001) and 1-RM (+9.7 ± 14.1% and +9.4 ± 13.5%, respectively; both P ≤ 0.05), with no significant between-group differences (all comparisons P > 0.05). RPE and perceived pain significantly reduced for G60 and G120 across training sessions (both P < 0.0001), but no between-group differences were shown (P = 0.98 and P = 0.52, respectively).

Conclusion

Both short and long inter-set rest intervals induce comparable neuromuscular and perceptual responses to LI-BFR.
类似的神经肌肉和知觉反应低强度训练与血流限制在短与长间歇休息
背景:在低强度血流量限制运动(LI-BFR)中增加间歇休息时间可能会加剧代谢应激,潜在地增强肌肉力量和对LI-BFR的肥大反应。相反,知觉反应(感知用力率[RPE]和疼痛)可能会随着间歇休息时间的增加而进一步受损。目的比较短休息间隔和长休息间隔对LI-BFR的神经肌肉和知觉反应。随机受试者内设计。方法体力活动男性13例(22±6 y;1.75±0.06 m;75.9±13.8 kg),在倾斜腿推运动中进行单侧LI-BFR(30%单次最多,1-RM),每组间一条腿休息60秒(G60),另一条腿休息120秒(G120)。训练方案为15次/组、3组/次、4次/周,持续3周,训练压力为动脉闭塞压力的80%。通过磁共振成像测量整个股四头肌的横截面积(CSA)。在基线和训练后评估CSA和1-RM。RPE和疼痛在每组训练后的初始、中期和最后阶段进行评估。结果G60和G120对提高全股四头肌CSA的效果相似,分别为+5.7±3.0%和+5.4±2.5%;P <;0.0001)和1-RM(+ 9.7±14.1%,+ 9.4±13.5%,分别;P≤0.05),组间差异无统计学意义(P >;0.05)。G60和G120组的RPE和感知疼痛在训练期间显著降低(P <;0.0001),组间差异无统计学意义(P = 0.98、P = 0.52)。结论短休息时间和长休息时间对LI-BFR的神经肌肉和知觉反应具有可比性。
