Background: The aim of this study was to determine the influence of different percentages of blood flow restriction (BFR) and loads on mean propulsive velocity (MPV) and subjective perceived exertion during squat (SQ) and bench press (BP) exercises. Hypothesis: Higher percentages of BFR will positively affect dependent variables, increasing MPV and reducing perceived exertion. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: Eight healthy young male athletes took part. Two sets of 6 repetitions at 70% 1-repetition maximum (1RM), 2 sets of 4 repetitions at 80% 1RM, and 2 sets of 2 repetitions at 90% 1RM were performed randomly; 5-minute recoveries were applied in all sets. The varying arterial occlusion pressure (AOP) applied randomly was 0% (Control [CON]), 80%, and 100%. Results: No statistically significant differences in MPV were found during the BP exercise at any percentage of BFR at any percentage 1RM. During the SQ exercise, MPV results showed statistically significant increases of 5.46% (P = 0.04; η p2 = 0.31) between CON and 100% AOP at 90% 1RM. The perceived exertion results for the BP exercise showed statistically significant reductions of -8.66% (P < 0.01; η p2 = 0.06) between CON and 100% AOP at 90% 1RM. During the SQ exercise, the perceived exertion results showed significant reductions of -10.04% (P = 0.04; η p2 = 0.40) between CON and 100% AOP at 80% 1RM; -5.47% (P = 0.02; η p2 = 0.48) between CON and 80% AOP at 90% 1RM; and -11.83% (P < 0.01; η p2 = 0.66) between CON and 100% AOP at 90% 1RM. Conclusion: BFR percentages ~100% AOP at 90% 1RM improved acutely MPV (only in SQ exercises) and reduced acutely perceived exertion (in both exercises). These findings are important to consider when prescribing resistance training for healthy male athletes. [ABSTRACT FROM AUTHOR]

Background: Physical exercise seems to have positive effects regarding the rehabilitation of alcohol-use disorders patients. However, there is still no consensus in the literature, and it is still unclear which type of exercise is optimal. The objectives of this review were to explore the benefits of exercise in this population as well as the specific type of exercise that should be prescribed. Methods: In accordance with the Prisma statement, Scopus, PubMed, and Web of Science databases were consulted. 31 articles were selected. PEDro scale was used to analyze the methodological quality of the included studies. Results: Aerobic and mixed exercise showed benefits for physical fitness, anxiety, and depression. Vigorous aerobic exercise intensity can reduce craving and encourage abstinence. Yoga appears to be effective at improving quality of life and reducing stress, depression, and craving levels. When exercise is performed at moderate or vigorous intensity, aerobic exercise has a greater acute effect on craving than when it is performed at a light intensity. Similarly, long-term results were slighter better when exercise intensity and number of weekly sessions were greater. Conclusion: It is recommended to include aerobic, aerobic-strength or yoga programs in order to improve the recovery process in alcohol disorders patients. [ABSTRACT FROM AUTHOR]
