Excusing us for not representing the population with the model in scope above.😉

📑📚Though, we are not short in papers elucidating the potential effect of BFR Training. A recent review and meta-analysis have assessed whether Low-load BFR resistance training (BFR) is comparable to conventional high-load and Low-load resistance training (HL) and (LL), respectively, for muscle strength and hypertrophy in healthy older adults.

As a sub-analysis, the review also explored the influence of cuff pressure on these outcomes.

A comprehensive search, including all relevant research databases, resulted in the inclusion of 14 studies.

The review found moderate-quality evidence suggesting that BFR produces less muscle strength gains VS HL.

Low-quality evidence showing similar improvements in muscle hypertrophy as BFR VS HL.

BFR was found to produce greater increases in muscle strength VS LL (moderate quality).

And greater increases in hypertrophy for BFR VS LL, as low-quality evidence.

Concerning the influence of BFR cuff pressure on muscle strength and hypertrophy in older adults, finding no difference when applying pressure near or even greater than Limb Occlusion Pressure (LOP) VS HL

However, higher cuff pressures during BFR resulted in greater improvements in muscle strength VS conventional LL.

💡Discussion and Conclusion:
These findings suggest that BFR can be an effective method for increasing muscle strength and hypertrophy in healthy older adults, with the potential for greater benefits when higher cuff pressures are applied.

Like reviews on younger populations, this review indicates that BFR training results in lower muscle strength gains but similar improvements in muscle hypertrophy VS HL resistance training in healthy older adults.

Also, to be expected, BFR was found to produce greater gains in terms of muscle strength and hypertrophy compared to LL in this older population.

Cuff pressures near LOP during BFR training may enhance muscle strength gains.

As a conclusion of these findings, the authors state: “.. evidence of an increased interest in the efficacy of LL-BFR resistance training on the muscle strength and hypertrophy in healthy older adults ..”

As a platitude, the researchers want “More research is needed to investigate the clinical and physiological effects of high or low pressures ..” and do not mention the well-established pressure-load continuum in this regard. Though, the present findings are contradictory to the results from another recent paper by Zhang et al.
