Increased muscle size following 12 weeks of elastic band blood flow-restricted training was well maintained (6.9% above pre-training levels) after 12 weeks of detraining in older women.

BACKGROUND: We examined the effects of detraining after blood flow-restricted (BFR) low-load elastic band training on muscle size and arterial stiffness in older women. FINDINGS: Fourteen women were divided into BFR training (BFR-T) or non-BFR training (CON-T). Each group participated in 12 weeks of arm curl and press down training using an elastic band either with (BFR-T) or without BFR (CON-T). Muscle cross-sectional area (CSA) and maximum voluntary isometric contraction (MVIC) for upper arms and cardio-ankle vascular index (CAVI) were evaluated before and after the 12-week training period and also after 12 weeks of detraining. CSA and MVIC were higher at post and detraining (CSA: 16.3% (p 0.05) for elbow extension; MVIC: 7.3 and 3.9% (both p > 0.05) for elbow flexion and 17.6 and 15.1% (both p < 0.01) for elbow extension) than at pre for the BFR-T, but not for the CON-T. There was no change in CAVI for the two groups. CONCLUSIONS: Increased muscle strength/size following 12 weeks of elastic band BFR-T was well maintained with a low risk of arterial stiffness after 12 weeks of detraining in older women.
Yasuda et al. (Tue,) conducted a rct in Sarcopenia (untrained older women) (n=14). Blood flow-restricted (BFR) low-load elastic band training vs. Non-BFR low-load elastic band training was evaluated on Muscle cross-sectional area (CSA) for elbow flexion after 12 weeks of detraining compared to pre-training (p=<0.01). Increased muscle size following 12 weeks of elastic band blood flow-restricted training was well maintained (6.9% above pre-training levels) after 12 weeks of detraining in older women.
