Abstract
Introduction: Blood flow restriction (BFR) training is a novel training method that has been shown to elicit positive aerobic and anaerobic physiological adaptations under low intensity. Using a pneumatic cuff placed distally on the limb to restrict blood flow and create an anaerobic environment within exercising muscle in order to elicit muscular adaptations. This has been shown to have a direct positive effect on respiratory variables as well such as VO2max. Purpose: The purpose of this study is to observe the effects of peripheral bilateral lower limb BFR during stationary recumbent bike training on VO2max and respiratory adaptations over seven weeks of biweekly training.
Methods: Eight (4 males and 4 females) sedentary, recreationally active adult subjects were randomly assigned to either the BFR (n=5, BFR) group or non-BFR (n=3, CON) group. Three testing sessions were conducted throughout the study (pre-training, mid-training, post-training) which consisted of anthropometric measurements and a graded cycle ergometer VO2max test using the COSMED-K5 metabolic analyzer. The test consisted of 2 min stages, starting at 100W and increasing by 25W until volitional fatigue. Each BFR training session consisted of a 5 minute warm up without BFR cuffs, application bilaterally of BFR cuffs to the proximal upper thigh region and inflation to 60% (BFR) or 5% (CON) of arterial occlusion pressure (AOP), 20 min of cycling at a heart rate reserve (HRR) of 35-45%, and a 5 minute cool down without BFR cuffs.
