Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
OTHER	Resistance exercise	The training session included leg curl and leg extension exercises with 4 sets each. Participants started with leg extension exercise for 4 sets with a 30-second rest periods between the sets. Then, participants took a rest for 60 seconds. Afterward, participants performed leg curl exercise for 4 sets with a 30-second rest periods between the sets. Exercises in each set were performed continuously (uninterrupted) with a speed of 2 seconds for each repetition and a medium exercise performance speed.
