Effect of Concurrent Training with Blood Flow Restriction in the Elderly

Abstract The aim of this present study was to investigate on the effects of concurrent training with blood flow restriction (BFR-CT) and concurrent training (CT) on the aerobic fitness, muscle mass and muscle strength in a cohort of older individuals. 25 healthy older adults (64.7±4.1 years; 69.33±1...

Zusammenfassung:Abstract The aim of this present study was to investigate on the effects of concurrent training with blood flow restriction (BFR-CT) and concurrent training (CT) on the aerobic fitness, muscle mass and muscle strength in a cohort of older individuals. 25 healthy older adults (64.7±4.1 years; 69.33±10.8 kg; 1.6±0.1 m) were randomly assigned to experimental groups: CT (n=8, endurance training (ET), 2 days/week for 30–40 min, 50–80% VO 2peak and RT, 2 days/week, leg press with 4 sets of 10 reps at 70–80% of 1-RM with 60 s rest), BFR-CT (n=10, ET, similar to CT, but resistance training with blood flow restriction: 2 days/week, leg press with 1 set of 30 and 3 sets of 15 reps at 20–30% 1-RM with 60 s rest) or control group (n=7). Quadriceps cross-sectional area (CSAq), 1-RM and VO 2peak were assessed pre- and post-examination (12 wk). The CT and BFR-CT showed similar increases in CSAq post-test (7.3%, P< 0.001; 7.6%, P< 0.0001, respectively), 1-RM (38.1%, P< 0.001; 35.4%, P =0.001, respectively) and VO 2peak (9.5%, P =0.04; 10.3%, P =0.02, respectively). The BFR-CT promotes similar neuromuscular and cardiorespiratory adaptations as CT.
