This study aimed to determine the optimal platform height in the maximum-speed single-leg bridge test (MS-SLBT) to maximize hamstring activation. This cross-sectional study included 26 healthy male recreational athletes. Participants performed the MS-SLBT using 20, 40, and 60 cm platforms at maximal speed. The conventional single-leg bridge test (SLBT) was performed on a 60 cm platform at any speed. Measurements included buttock-raising speed; muscle activity of the semitendinosus (ST), biceps femoris (BF), and gluteus maximus (GM) using surface electromyography; and heel-bearing force. MS-SLBT showed significantly faster buttock-raising speeds (0.7-1.0 m/s) than SLBT (0.5 m/s) (p<0.01). ST and BF muscle activities were significantly higher during MS-SLBT on 60 and 40 cm platforms (>90% maximal voluntary isometric contraction) than during SLBT and MS-SLBT on 20 cm platform (p<0.01). GM muscle activity during MS-SLBT was approximately double than that during SLBT(p<0.01). Heel-bearing force was significantly higher during MS-SLBT than during SLBT, MS-SLBT on 40cm platform showing the highest force (p<0.01). MS-SLBT on 40 and 60 platforms required higher hamstring activity, with faster buttock-raising speed and greater heel-bearing force than SLBT and MS-SLBT on 20 platform.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four databases were searched for peer-reviewed English-language studies, and the risk of bias and quality of evidence were assessed using RoB 2 and GRADEpro GDT. We evaluated pre- and post-test differences by a three-level meta-analysis using the meta and metafor packages. Subgroup analyses and both linear and nonlinear meta-regression methods were used to explore moderating factors. Sixteen studies with 'some concerns' risk of bias and low evidence level were included. Combining BFR with low-intensity resistance training produced an effect size (ES) of 0.25 for strength, while combining BFR with aerobic training had an ES of 0.42. For aerobic capacity, the ES of combining BFR with aerobic training was 0.58. Subgroup and regression analyses showed no significant differences. While BFR with low-intensity resistance training enhances strength, it does not result in additional gains. Adding BFR with aerobic training enhances both strength and aerobic capacity. Overall, BFR appears to offer the most benefits for male athletes in improving strength and aerobic capacity.","PeriodicalId":14439,"journal":{"name":"International journal of sports medicine","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following a graded exercise test to determine maximal oxygen uptake intensity (iVO2max), 26 recreational runners performed a time to exhaustion effort (TTE) as baseline at 110% iVO2max. The same TTE was performed in fasting state, then, a muscle glycogen depletion protocol was executed. Subsequently, participants received a low-carbohydrate diet and beverages containing high (H-CHO, 10.8±2.1 g·kg- 1), moderate (M-CHO, 5.6±1.1 g·kg- 1), or zero (Z-CHO, 0.24±0.05 g·kg- 1) carbohydrates. Another TTE was performed 24 h later. Each energy system contribution was assessed. Generalized linear mixed models were used for statistical analysis (p<0.05). H-CHO increased relative anaerobic capacity (slope effect [baseline -intervention]x[H-CHO - M-CHO]) due to the relative lactic contribution maintenance (slope effect [baseline - intervention]x[H-CHO - Z-CHO] or [H-CHO - M-CHO]) and increase in relative alactic contribution (6.3±3.5 kJ·min- 1). The aerobic contribution was lower (- 8.7±4.0 kJ·min- 1), decreasing performance (- 34±16 s) for H-CHO. M-CHO and Z-CHO maintained anaerobic capacity due to increase in alactic contribution (slope effect [fasting - intervention]x[M-CHO - H-CHO]; and Z-CHO was 7.3±3.4 kJ·min- 1 higher than baseline). Fasting increased relative alactic (2.9±1.7 kJ·min- 1) but decreased aerobic contribution (- 3.3±2.3 kJ·min- 1), impairing performance (- 17±12 s). In conclusion, MAODalt can detect changes in energy system supply in different nutritional states.
