Blood flow restriction added to online low-intensity training in older adults
In a 10-week online study, older adults doing low-intensity resistance training twice weekly improved strength and function; the blood flow restriction group showed greater gains, mainly in functional performance. [1]

Online low-intensity training with blood flow restriction in older adults
The study asked whether combining blood flow restriction (BFR) training with online exercise classes improves strength and functionality in older adults. BFR means limiting blood flow to specific areas so that low-intensity exercise can mimic high-intensity workouts. Over ten weeks, 41 men and women (mean age 70 ± 6.2 years) took part in Zoom sessions twice a week.

Greater functional gains in the BFR group than in controls
Participants were divided into 22 in the BFR group and 19 controls (CON). Hamstring and quadriceps strength was measured with a dynamometer; functionality was tested with the 30-second sit-to-stand, the 8-foot timed up-and-go and the 30-second calf raise. Both groups improved in muscle strength and lower extremity functionality, but the BFR group achieved greater gains, mainly in functional performance.

Preliminary evidence from an abstract of 41 participants
The authors describe the evidence as preliminary and suggest BFR may add a physiological stimulus to low-intensity exercise without increasing mechanical load. They present this as a novel, accessible and practical strategy for functional mobility in aging populations, particularly for people unable or unwilling to do higher-intensity training. The abstract reports no effect sizes or statistical uncertainty, and the full text was not reviewed.
