Purpose: Blood flow restriction training is increasingly becoming widespread among athletes. However, little is known concerning application modalities and management of discomfort among runners. This study aimed to determine whether continuous training with BFR could improve cardiorespiratory endurance in runners.
Methods: 46 subjects were randomly allocated into 4 groups. Pre- and post-training measurements of anthropometric data, resting heart rate (HR), calves and thighs girths and a maximal graded endurance test on treadmill providing maximal aerobic speed (MAS) to estimate maximal oxygen uptake (VO2max) were performed, while rating of perceived exertion (RPE) was evaluated. Perception of tightness was measured during sessions. Each week for 4 weeks, subjects performed 2 sessions in autonomy (70% of MAS) and 1 session in the laboratory where continuous groups were respectively running at 70% of MAS with the minimal occlusion pressure (CT) and 40% of MAS with 160–220 mmHg (CT-BFR), during 30–40 min. Interval groups completed 3 sets of 4–6 repetitions alternating 1 min of effort with 1 min of active rest (IT: 100% of MAS / 50% of MAS without BFR; IT-BFR: 50% of MAS / walk at 3.5 km.h-1, with 160–220 mmHg of occlusion pressure). Bands were deflated during the 2-min of active recovery between sets (walk at 3.5 km.h-1). One-way ANOVA with interpretation of effect size allowed to assess the effects of the intervention. Results: 39 participants completed the protocol. VO2max increased in CT (ES = 0.50), IT (ES = 0.35) and IT-BFR (0.25), but there was no difference between groups (p = 0.084). CT-BFR did not report any difference in VO2max (p = 0.351) and resting HR (p = 0.722) while it largely decreased only in IT (ES = 0.82). During training, IT-BFR and CT-BFR showed a lower mean percentage of maximal HR (p Conclusion: Continuous training at low intensity with BFR did not allow to improve VO2max. Exercise intensity was a more determinant parameter than occlusion in healthy runners. |
