Hemodynamic Responses to Resistance Exercise With Restricted Blood Flow in Young and Older Men
Why the study?
Does low-intensity resistance exercise with blood flow restriction alter acute hemodynamic responses compared to exercise without restriction in young and older men?
Population
27 men, comprising 15 young (mean age 30 ± 3 years) and 12 older (mean age 66 ± 7 years) subjects
Comparison
Low-intensity resistance biceps curl exercise… vs Low-intensity resistance biceps curl exercise…
Design
RCT, random and crossover design
Follow-up
acute (during exercise and recovery period)

Implication
BFR-RE warrants closer hemodynamic monitoring than RE; extends RCT evidence on acute responses across age groups.
Structured PICO
Does low-intensity resistance exercise with blood flow restriction alter acute hemodynamic responses compared to exercise without restriction in young and older men?
P
Population
27 men, comprising 15 young (mean age 30 ± 3 years) and 12 older (mean age 66 ± 7 years) subjects
I
Intervention
Low-intensity resistance biceps curl exercise with blood flow restriction (BFR-RE)
C
Comparator
Low-intensity resistance biceps curl exercise without blood flow restriction (RE)
O
Outcome
Hemodynamic responses including heart rate (HR), mean blood pressure (MBP), calf blood flow (CBF), and calf vascular resistance (CVR)surrogate
Resistance exercise with blood flow restriction elicits greater acute hemodynamic changes, including increased heart rate, blood pressure, and vascular resistance, compared to unrestricted exercise in both young and older men.
