Summary Blood flow restriction ( BFR ) training stimulates muscle size and strength by increasing muscle activation, accumulation of metabolites and muscle swelling. This method has been used in different populations, but no studies have evaluated the effects of training on muscle power and submaximal strength ( SS ) in accounted for the menstrual cycle. The aim of this study was to analyse the effect of strength training ( ST ) with BFR on the muscle power and SS of upper and lower limbs in eumenorrheic women. Forty untrained women (18–40 years) were divided randomly and proportionally into four groups: (i) high‐intensity ST at 80% of 1 RM ( HI ), (ii) low‐intensity ST at 20% of 1 RM combined with partial blood flow restriction ( LI + BFR ), (iii) low‐intensity ST at 20% of 1 RM ( LI ) and d) control group ( CG ). Each training group performed eight training sessions. Tests with a medicine ball ( MB ), horizontal jump ( HJ ), vertical jump ( VJ ), biceps curls ( BC ) and knee extension ( KE ) were performed during the 1st day follicular phase (FP), 14th day (ovulatory phase) and 26–28th days (luteal phase) of the menstrual cycle. There was no significant difference among groups in terms of the MB , HJ , VJ or BC results at any time point ( P >0·05). SS in the KE exercise was significantly greater in the LI + BFR group compared to the CG group ( P = 0·014) during the LP. Therefore, ST with BFR does not appear to improve the power of upper and lower limbs and may be an alternative to improve the SS of lower limbs of eumenorrheic women.
