Abstract

Maximal oxygen consumption (VO₂ max) reflects the greatest amount of oxygen utilized upon exertion. Blood flow restriction (BFR) limits venous return, enabling low-intensity exercise to yield adaptations like high-intensity training. This study examined whether 5 weeks of online resistance training (RT) with BFR straps improves VO₂, tidal volume, and respiratory frequency in older adults. Twenty-five participants (mean age: 70 ± 5.6) completed bi-weekly trainings. VO₂ and respiratory measures were assessed during a 30-second sit-to-stand test. The BFR group showed significant VO₂ gains, while respiratory measures remained unchanged. BFR may offer an effective strategy to enhance aerobic capacity in aging adults.

Research summary

The paper claims that 5 weeks of online resistance training with blood flow restriction improves oxygen consumption in older adults. This research is relevant as it explores a potential intervention to enhance aerobic capacity in aging adults, addressing aspects of physical decline associated with aging.
