Twelve trained men were enrolled in a randomized, double-blind, crossover study. Each participant underwent two interventions with a 14-day washout period: i) alkalosis (ALK) – administration of gelatinous capsules containing 0.3 g.kg -1 of NaHCO 3 ; ii) placebo (PLA) – administration of capsules containing 0.3 g.kg -1 of calcium carbonate (CaCO 3 ). The outcomes (electromyographic activity of the quadriceps, peak torque, pH, lactate, scales of perceived effort and pain) were collected during a dynamic high-intensity intermittent protocol performed on an isokinetic dynamometer. Repeated-measures ANOVA revealed no differences between conditions for any of the outcomes analysed.

Although several variables contribute to the maximum load lifted, upper limb variables may also play an important role in BP performance. In this study, a cohort of 47 male Italian classic powerlifters underwent a direct anthropometric evaluation during two official competitions. The recorded parameters included body mass index, body composition, and variables of the upper limb (indirectly evaluated cross-sectional areas and lengths). IPF-GL points and maximal strength (1RM) adjusted for weight were used as proxies for performance. Statistical comparisons between weaker and stronger powerlifters, Pearson correlation and partial correlation analyses, and multiple linear regression models were performed. The upper arm cross muscular area (r = 0.56) and fat-free mass (r = 0.31) were positively correlated with Wilks points, whereas the arm fat index was negatively correlated with 1RM BP (r = -0.37). Moreover, we proposed two new indices (UALR and UAMR) that represent the ratio between upper arm areas and length. Both univariate and multivariate analyses confirmed the strong association between these two variables and BP performance. Further improvement of this study may confirm the important role of body proportion and body composition as predictors of performance in strength sports.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the concurrent validity of different technological approaches measuring barbell velocity, video-analysis (Kinovea), linear velocity transducer (Speedograph), and an inertial measurement unit (V max Pro) were compared. Sixty-eight female and male sport science students lifted two repetitions in the bench press exercise at self-selected barbell loads. Peak vertical barbell velocity (V max ) was parallel measured during the concentric phase of the lift using the aforementioned devices. Concordance correlation coefficient (CCC), Deming regression (DR) and Bland-Altman analysis (BA) were used to assess relative and absolute concurrent validity of V max measured with Kinovea, Speedograph, and V max Pro. Results confirmed high concurrent validity of Speedograph and V max Pro (CCC = 0.99, standard deviation of differences [SDD] = 0.04 m∙s -1 ) without detecting proportional or constant bias. In contrast, V max measured with Kinovea showed poor concurrent validity to Speedograph (CCC = 0.83) and V max Pro (CCC = 0.81) with significant proportional and constant bias. Regression based re-calibration of V max from Kinovea resulted in an SDD = 0.09 m∙s -1 compared to Speedograph and an SDD = 0.08 m∙s -1 compared to V max Pro. Among the three tested devices, V max assessed using Kinovea showed poor concurrent validity. Furthermore, as Kinovea showed proportional bias compared to Speedograph and V max Pro, application-specific re-calibration of Kinovea should be applied when barbell velocity data is compared to Speedograph and V max Pro.","PeriodicalId":51651,"journal":{"name":"Journal of Human Sport and Exercise","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66692523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
