The ingestion of beetroot juice (BJ) has been associated with improvements in physical performance in endurance sports, however the literature on resistance training (RT) is scarce. The aim of this study was to investigate the acute effects of BJ compared to a placebo (PLA) on muscular endurance and movement concentric velocity during RT. Twelve healthy men performed an incremental RT test (back squat and bench press) with three sets, at 60%, 70%, and 80% of their repetition maximum (1-RM). Movement velocity variables, total number of repetitions performed until concentric failure, blood lactate, and ratings of perceived effort post-training were measured. A higher number of repetitions were recorded with BJ compared to those with PLA (13.8 ± 14.4; p < 0.01; effect size (ES) = 0.6). Differences were found at 60% 1-RM (9 ± 10; p < 0.05; ES = 0.61) and 70% 1-RM (3.1 ± 4.8; p < 0.05; ES = 0.49), however, no differences were found at 80% 1-RM (1.7 ± 1; p = 0.12; ES = 0.41). A greater number of repetitions was performed in back squat (13.4 ± 13; p < 0.01; ES = 0.77), but no differences were observed in bench press (0.4 ± 5.1; p = 0.785; ES = 0.03). No differences were found for the rest of the variables (p > 0.05). Acute supplementation of BJ improved muscular endurance performance in RT.

The aim of this study is to show that the implementation of the Safe Fall programme in physical education classes can help to reduce the negative effects of unintentional backward falls in the adolescent population, by teaching them how to protect themselves when falling. A quasi-experimental research design was applied in a sample of 120 children (M = 15.1 years, SD = 2.45), attending a secondary school in Seville (Spain). Data was collected on an ad hoc observation scale INFOSECA (which records five basic elements during a backward fall: position of the neck, the hands, the trunk, the hips, and the knees), applying descriptive, correlational, and contrast statistics. The criteria for considering statistical significance was p < 0.05 in McNemar’s test. The data indicates that learning safe and protected ways of falling backward is possible through the implementation of the Safe Fall programme, and no differences were found in terms of gender.
