The Study
Effects of Acute Upper and Lower Body Resistance Exercise on Cardiovascular Response in Adult Women Through Blood Flow Restriction.
This study watched how 18 young women’s hearts and blood pressure reacted when they did light weightlifting with special bands on their arms and legs. It found that their heart rates and blood pressure changed differently depending on whether they lifted with their arms or legs, but it didn’t prove the bands caused those changes — it just saw a pattern.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
When you do leg exercises with bands that squeeze your thighs or arms, your heart pumps more blood — but legs with bands make your heart work way harder than arms with bands.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — this means leg workouts with BFR put more stress on the heart during exercise but may help lower blood pressure afterward, which could be useful or risky depending on health.
- 2Leg exercises with bands raised heart rate by ~30% and cardiac output by ~50% more than arm exercises with bands.
- 3Blood pressure spiked higher during leg workouts but dropped more after.

Resistance exercise that uses large muscle groups raises the amount of blood the heart pumps per minute by increasing both heart rate and the volume of blood pumped with each beat.
During resistance exercise with blood flow restriction, healthy young women experience greater increases in diastolic blood pressure and mean arterial pressure when exercising the lower body compared to the upper body.
When young women perform resistance exercise with restricted blood flow, their blood vessel resistance rises temporarily during the workout and drops significantly afterward.
When young women perform lower body resistance exercises with blood flow restriction, their heart rate and cardiac output rise more than when they perform upper body resistance exercises with the same restriction, reflecting greater cardiovascular demand from larger muscle groups.
In young women, performing resistance exercise with blood flow restriction leads to a temporary decrease in diastolic blood pressure and mean arterial pressure after exercise, which is linked to a reduction in total peripheral resistance.
In young women, performing resistance exercise with restricted blood flow leads to a larger increase in stroke volume during recovery than without restricted blood flow, reflecting a slower adjustment of heart function to metabolic demands.
