In other sports, training load has been prospectively investigated and shown to influence injury risk. However, no method to quantify training load in powerlifting exist. The purpose of this study was to assess the feasibility of a novel standardized method for prospective recording of training load and injuries. The study was conducted in two phases with eight powerlifters initially included in each phase respectively. In Phase 1, the powerlifters registered training load and injuries throughout four weeks and answered a feasibility questionnaire. Based on the results from the questionnaire, updates to the training and injury log were made and the powerlifters in Phase 2 used the updated version to log four weeks of training. Training load and injuries were reported consistently which made calculations on training load and injury incidence possible. The participants reported rate of perceived exertion as difficult to assess and report. However, 9/12 powerlifters stated that they could the training and injury log for a period of at least six months. In conclusion, this standardized training and injury log seems to be a feasible method to quantify training load and injuries in powerlifting. The method could be used in further prospective studies on training load and injuries in powerlifting and in clinical practice.","PeriodicalId":170948,"journal":{"name":"International Journal of Strength and Conditioning","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129015890","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}

Twenty-five college-age student- athletes participated in three, high-intensity anaerobic exercise conditions (treadmill sprint, barbell squat, and vertical jump) on three separate days with only one condition being performed per week in a randomized order. Dynamic balance became significantly (t = 2.21, p = 0.04) worse from pre- to post-testing after completing the vertical jump protocol (5.24 ± 2.29 and 6.1 ± 1.92, respectively). There were no significant (t < 1.75, p < 0.19) differences in dynamic balance from pre- to post- testing after performing the treadmill sprint (5.68 ± 1.68 and 6.28 ± 2.06, respectively) and barbell squat (5.18 ± 1.64 and 5.69 ± 1.81, respectively) protocols. While Tabata sprint and barbell squat protocols revealed no significant effects on dynamic balance, a similar-intensity Tabata vertical jump protocol produced a significant detriment in dynamic balance performance. These findings suggest that the vertical jump may uniquely hinder subsequent sport performance and increase risk of balance-related injury when compared to intensity- matched sprinting or squatting. These results may be attributable to an increased propensity to fatigue when performing bouts of vertical jump compared to sprinting or squatting, thus reducing the proprioceptive capability of the body.","PeriodicalId":170948,"journal":{"name":"International Journal of Strength and Conditioning","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125054197","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}

Statistically speaking, they are interval in nature as they may be positive or negative. The coefficient of variation (CV) is a commonly reported measure of variability, but its use with vector data is questionable and may be contraindicated. Limits of agreement (LOA) and standard error of measurement (SEM) may be better alternatives for vector data such as acceleration. The purpose of this study was to demonstrate the issues with quantifying variability of vector data, while also evaluating the utility of commonly used measures. Acceleration data at three intervals from 0 to 27.4 m (0 to 90 ft) were calculated from publicly available sprint performance data from 310 athletes participating in the 2018 and 2019 Major League Baseball seasons. CV, LOA, and SEM were calculated to evaluate inter-season variability. Variability of the first two intervals was acceptable for all measures, but the final interval was unclear as the CV was quite large (50.78%), while the LOA and SEM were only slightly larger than the other interval values. The final interval includes both positive and negative acceleration, contraindicating the usage of the CV. LOA and SEM are more useful for vector data, showing that the final interval was more variable between trials than the others, but not to the extent portrayed by the CV. The CV likely should not be used with vector data unless it is known that the data does not cross zero. LOA and SEM are appealing alternatives for the CV and should be considered since they work with positive and negative data.","PeriodicalId":170948,"journal":{"name":"International Journal of Strength and Conditioning","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124619639","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}

Method: Subjects were 10 full-time professional basketball players (24.6 ± 4.9 years old; 204.2 ± 16.8 cm; 97.9 ± 10.4 kg). Workload was recorded and classified as total duration training and duration of full game during a competitive season. A wearable tracking system collected eTL via Player Load (PL) and Player Load per minute (PL/min). Training sessions were classified based on days before a match (four days before the match day = MD-4, MD-3, MD-2, and MD-1), and MD. Session rate of perceived exertion (sRPE) and rate of perceived exertion (RPE) were used for iTL. In addition, the Hooper index (HI) was used for well-being. Results: A significant difference was found between MD-1 and MD workload, MD workload being the highest of all variables: RPE (p < .001), PL/min (p <.001), PL (p <.001), and sRPE (p <.001). Regarding Hooper’s categories, significant differences between training days and match were only found in soreness (p <.001). Conclusion: The results show that MD provides a unique stimulus in terms of volume and intensity. Consequently, coaches must incorporate specific training exercises to adapt players to the demands of competition. Finally, special attention should be paid to MD-2 and MD-1 in terms of potential accumulated fatigue and thus to ensure appropriate recovery time for athletes to adapt before the match.","PeriodicalId":170948,"journal":{"name":"International Journal of Strength and Conditioning","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774108","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}

The data set was from Powerlifting Championships recognized by the International Powerlifting Federation, compiled by the Open Powerlifting project. The records were 65,867 men’s and 35,679 women’s samples from classic powerlifting and 19,295 men’s and 7,426 women’s samples from equipped powerlifting, all with ages from 24 to 39 years from 2012 to November 2022. For each record, the SBD ratios were calculated by the mean of the formula (SBD discipline / Total score) by one hundred. Dispersion plots of Good Lift Points (GLP) score versus the SBD ratios and Bar plots of mean and variance of SBD ratios were done, highlighted by quantiles of GLP score. The Mean and Standard Deviation from Elite Powerlifters (90-100th quantiles) of each weight class were used to calculate the SBD ratio ranges. An algorithm with twenty-six permutations, where the addition and subtraction from 0.5 to 3 standard deviation to the mean marked the ranges' Upper and Lower borders. The best permutation by each weight class was selected when the athletes' group inside the optimal ratio ranges (ORR) showed the highest Impact Factor (GLP mean by frequency) and the shortest ORR. To evaluate the effectiveness of the ORR for each weight class in sexes and events were analyzed lower levels of Powerlifters, inside 0-50th and 50th-90th quantiles of GLP score. For these sets, was applied One Way ANOVA to evaluate the meaning differences between IN and OUT groups from ORR, using post-hoc test of Tukey's HSD or Games-Howell. From sixty-four evaluations, forty-eight were higher in GLP mean score for the IN group, meaning differences regarding the OUT group.

The use of Body Mass Index (BMI) based equations for such purposes has been found to be relatively invalid in athletes due to the inability to decipher between fat and fat-free mass. Recently, a BMI based equation developed by Nickerson et. al. (BMINICKERSON) that incorporates handgrip strength as a surrogate for lean mass was found to estimate body fat with low error in general population adults. The use of such a method in collegiate athletes may in turn provide a cost-effective and easily administered option for body composition assessment. PURPOSE: To compare the effectiveness of BMINICKERSON with traditional body composition methods in estimating body fat percentage of collegiate athletes. METHODS: Forty-one (n = 41) intercollegiate athletes (n = 21 male, 20 female) were assessed for percentage body fat using BMINICKERSON, bio-electrical impedance analysis (BIA) and seven site skinfold (SF). Pearson’s correlation was utilized to assess relationships among measurements methods. A sex x measurement method Two-Way ANOVA with repeated measures on the latter was utilized to determine potential differences in body fat percentage as estimated by each method between males and females. RESULTS: Good to excellent agreement was displayed between BIA and BMINICKERSON compared to SF in the total population and each sex (r > 0.76, p < 0.001). A significant interaction (F = 5.01, p = 0.01) between sex and measurement method was found for the sample. Paired samples t-testing in females revealed a significantly greater body fat estimation by BMINICKERSON (26.75 % ± 3.72 %) in comparison to both BIA (t = 7.73, p < 0.001, 22.36 % ± 2.80 %) and SF (t = 5.15, p < 0.001, 23.37 % ± 4.49 %). BIA and SF did not significantly differ (t = 1.51, p = 0.15) in females. Further paired samples t-testing in males revealed a significantly greater body fat estimation by BMINICKERSON (17.66 % ± 4.30 %) in comparison to both BIA (t = 8.74, p < 0.001, 13.15 % ± 4.28 %) and SF (t = 8.78, p < 0.001, 11.73 % ± 4.38 %). In addition, a significantly greater (t = 2.10, p = 0.05) body fat estimation was found using BIA in comparison to SF in males. CONCLUSION: Although the use of BMINICKERSON in estimating body composition has been shown to provide relatively accurate results in the general population, the current study did not observe the same in collegiate athletes. Further research comparing BMINICKERSON to a gold standard measurement technique in collegiate athletes is warranted.","PeriodicalId":170948,"journal":{"name":"International Journal of Strength and Conditioning","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124889394","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}
