Impact of blood flow restriction on metabolic stress neuromuscular fatigue Nutritional, Metabolic, Endocrine
Conditions
Interventions
Using a randomized, cross-over design, participants completed one of two experimental conditions: Low load (30% of 1 repetition maximum) + Blood flow restriction (BFR
or High load (65% of 1 repetition maximum [1RM]) + non-BFR. Participants were randomized using a free online randomization tool. During baseline testing, participants had limb occlusion pressure (50%)
Norsearch, Australia). In both conditions, participants completed 1 set of 30 repetitions in their respective resistance training protocol, at the assigned load, and then 3 sets with a maximum number

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Blood lactate measured using a Lactate Scout (Sports Resource Group, USA) handheld analysis device at baseline and following the 4th (final) set of back squat exercises 2. Vertical jump height measured using a 27” x 27” jump mat (Just Jump System, Probotics, AL, USA) at baseline and following the 4th (final) set of back squat exercises | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Ratings of perceived exertion measured using Borg’s 10-point ratings of perceived exertion (0-10) scale at baseline and immediately following each set of the back squat exercise 2. Hemodynamic responses measured using a mercurial sphygmomanometer (American Diagnostic Corporation, model #AD-720) before and after the back squat exercise, in addition to post-inflation of the BFR cuffs for the BFR condition only | — |
