Brief 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.

Low load resistance exercises with Practical blood flow restriction (PBFR)

EXPERIMENTAL

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.

Other: Resistance exercise

High resistance exercises

ACTIVE COMPARATOR

Participants in the control group performed one session of 80% 1RM without PBFR. The number of repetitions in every set was 10 times.

Other: Resistance exercise

Interventions

Resistance exercise OTHER

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.
