In this one, a low-intensity resistance training with blood flow restriction (BFR) was associated with superior improvements in macrovascular and microvascular function compared with a traditional high-intensity resistance training program in healthy, young men.

- This study aimed to determine the macrovascular and microvascular function responses to low-intensity resistance training with blood flow restriction compared to a high-load resistance training control group.

- Twenty-four young, healthy men participated.

- Participants performed bilateral knee extensions and leg presses 4 days per week, for 4 weeks. For each exercise, the low-intensity resistance training with blood flow restriction completed 3 X 10 repetitions/day at 30% of 1-repetition max.

The occlusive pressure was applied at 1.3 times of individual ankle systolic blood pressure.

The exercise prescription was identical for the high-load resistance training group, except the intensity was set at 75% of one repetition maximum.

- Macrovascular function, as assessed by heart-ankle pulse wave velocity (haPWV) was associated with a 5% improvement in the low-intensity resistance training with blood flow restriction group, but did not in the traditional high-intensity resistance training group.

- Microvascular function, as assessed by area under the curve of the medial gastrocnemius tissue oxygen saturation improved for both groups, but the effect was stronger for the low-intensity resistance training with blood flow restriction group (17%)...

...compared to the traditional high-intensity resistance training group (5%).
