Summary

This study is aiming to compare the CRF utilizing LIRT-BFR and MIRT in the elderly. Both techniques provided comparable gains in VO₂ max and the BORG scale. The BFR group displayed a greater level of safety for elderly to undertake resistance training with the same benefit as the MIRT group.

Conditions

  • Cardiorespiratory Fitness

Interventions

OTHER

Low Intensity Resistance Training and Blood Flow Resistance

The LIRT-BFR group used a cuff on the upper third of the thigh with a restriction pressure of 50 mmHg or 40% Arterial Occlusion Pressure to apply BFR while engaging in low-load resistance training that targeted the quadriceps femoris muscle at an intensity of 20-30% of 1-RM. The resistance training protocol consists of four sets of knee extensions using an ankle weight in a sitting position. Each set consists of 30 repetitions on the first set and 15 repetitions each on sets 2-4 with a 30-second interval between sets. The air pressure cuff was deflated during the interval period. In the third week, the weight load was recalculated to 40% of 1-RM in order to accommodate subsequent 1-RM testing procedures.

OTHER

Moderate Intensity Resistance Training

The MIRT group conducted three sets of moderate-intensity resistance training, concentrating on the quadriceps femoris muscle, with weights set at 40-60% of their 1RM or higher. While the MIRT protocol resembled that of LIRT-BFR, each set comprised 8-12 repetitions, followed by a 2-minute rest between sets. In the third week, the 1-RM testing protocol was revised, with the weight adjusted to 60% of the 1-RM.
