简要总结
Practical blood flow restriction (PBFR) is a new technique of reducing the venous return using a band with a pressure that is applied using a perceived pressure scale. The studies that investigate the acute effect of using PBFR and regular high intensity exercises on the level of growth hormone (GH) and blood lactate (BL) after lower extremity training in collegiate athletes are scarce.
详细描述
Practical blood flow restriction (PBFR) is a new technique of reducing the venous return using a band with a pressure that is applied using a perceived pressure scale. The studies that investigate the acute effect of using PBFR and regular high intensity exercises on the level of growth hormone (GH) and blood lactate (BL) after lower extremity training in collegiate athletes are scarce. Therefore, this study aimed to investigate the acute effect of a single session low load resistance exercises with PBFR compared to a high load resistance exercises without PBFR on the levels of GH and BL. A convenience sample of collegiate athletes were allocated to either an experimental group that performed low resistance exercises with PBFR or a control group that performed high resistance exercises without PBFR. The levels of GH and BL were examined in 3 time points: pre-training, immediate post-training, and 15 minutes post-training for both groups. Analysis of Variance (ANOVA) was used to assess the main and interaction effects of the groups.

研究组 & 干预措施
Low load resistance exercises with Practical blood flow restriction (PBFR)
Participants in the experimental group performed one session of 30% 1RM with Practical blood flow restriction training. The number of repetitions in every set was 15 times with PBFR.19 Participants in the experimental group used the elite band (occlusion training bands) for both thighs during the training session. The width of the thigh band was 5cm, which would produce a pressure between 160-240 mmHg. This pressure range is appropriate for most of the individuals who used PBFR.27 The perceived pressure scale (PPS) was used to estimate the appropriate pressure (7 out of 10) in training before performing the exercises.28,29 The blood flow restriction bands booklet was used30 along with previous studies to design the training session. Participants removed the BFR band immediately after the end of the training session.
干预措施: Resistance exercise (Other)
High resistance exercises
Participants in the control group performed one session of 80% 1RM without PBFR. The number of repetitions in every set was 10 times.
