BACKGROUND: One repetition maximum (1 RM) test without blood flow restriction (BFR) may lead to misinterpretation of maximal strength and exercise capacity. The question of whether BFR should be applied during 1 RM tests for BFR training has not been definitively addressed in the literature. This study examined the difference between the 1 RM test results obtained with (BFR and without BFR.METHODS: Twenty-seven healthy (age 20.15±3.17 years; mass 74.59±6.95 kg; height 177.55±5.74 cm; Brachial Index: 1.09±0.10), physically active men performed two 1 RM tests in back squat (BS) with 80% of BFR (BFR80) and with 0% of BFR (BFR0) conditions. In both conditions, the weight lifted in the 1 RM test in the BS exercise and the repetitions to failure were measured.RESULTS: 1 RM test scores were significantly higher in BFR80 compared to BFR0 condition (BFR80 133.48±24.83 vs. BFR0 117.04±15,67; P<0.001). In addition, there is a significant difference between BFR80 and BFR0 conditions in terms of repetition to failure (RF) (BFR80 10.89±5.30 vs. BFR0 7.11 ±3.23; P<0.001).CONCLUSIONS: 1 RM test scores and RF were significantly higher in the BFR80 condition. Prior to BFR training, conducting 1RM tests in BFR conditions can help in determining the appropriate training intensity.
