Effects of exercise intensity and occlusion pressure after 12 weeks of resistance training with blood-flow restriction

Abstract

In conclusion, BFRT protocols benefit from higher occlusion pressure (80 %) when exercising at very low intensities. Conversely, occlusion pressure seems secondary to exercise intensity in more intense (40 % 1-RM) BFRT protocols. Finally, when considering muscle strength, BFRT protocols seem less effective than high-intensity RT.

Blood flow restriction training: a novel approach to augment clinical rehabilitation: how to do it

“…While the relationship between BFR pressure and the underlying tissue compression during exercise is not yet fully understood, BFR training using 40%–80% of limb occlusion pressure is safe and effective when supervised by experienced practitioners6; therefore, lower pressures may provide less risk without the need for higher pressure. Establishing limb occlusion pressure is quick and easy to perform with a handheld Doppler and may minimise any cardiovascular risk from the application of BFR during exercise,7 alongside pre-exercise screening.…”

Blood flow restriction and cuff width: effect on blood flow in the legs

“…These range from very narrow cuffs of 3 cm (Yasuda et al, 2012;Thiebaud et al, 2014) to very wide cuffs of up to 17Á5 cm (Laurentino et al, 2012;Lixandrão et al, 2015). These range from very narrow cuffs of 3 cm (Yasuda et al, 2012;Thiebaud et al, 2014) to very wide cuffs of up to 17Á5 cm (Laurentino et al, 2012;Lixandrão et al, 2015).…”

Exercise with blood flow restriction: an effective alternative for the non‐pharmaceutical treatment for muscle wasting

“…Regarding the occlusion pressure, we showed that high occlusion pressure (80% of the occlusion pressure) produces greater muscle hypertrophy than moderate occlusion pressure (40% of the occlusion pressure) when exercising at low intensities (20% of 1‐RM). Conversely, occlusion pressure does not seem to play a role when exercise intensity at ~40% 1‐RM . There is a lack of studies investigating whether different occlusion pressures could interfere on muscle and cardiorespiratory adaptations when undergoing ET‐BFR.…”

“…Two of the most common training methods are the low intensity RT and endurance training (ET) associated with BFR . Several randomized controlled trials and meta‐analyses have shown that RT with BFR (RT‐BFR) produces similar muscle hypertrophy response to high intensity RT, in different populations . The similar muscle hypertrophy response between low intensity RT‐BFR and high intensity RT may be due to the fact that both training strategies activate similar physiological/molecular mechanisms.…”
