The sample comprised 471 games between 2007 to 2017. The games were grouped into three clusters (balanced games - difference of 1 to 8 goals; unbalanced games - difference of 9 to 20 goals; very unbalanced games - difference of > 20 goals). In comparisons of means, the performance of winning teams is significantly higher (most variables), or lower in the case of number of technical fouls (p < .05). In balanced games, there is a greater contribuition of defensive variables (stollen balls, blocked throws and goalkeeper efficiency) in relation to attack variables (attack efficiency and throw efficiency). For victory, the number of technical fouls reduces to a lesser extent the chances of winning. Games with unbalanced and very unbalanced scores seem to follow a same tendency. We conclude that the decisive variables for victory showed a greater weight with a special emphasis on stolen balls followed by offensive variables (throw efficiency, attack efficiency and technical fouls) in balanced games.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":"52 1","pages":"54-63"},"PeriodicalIF":1.2,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/k.52.1.6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48485318","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}

Twenty junior and 25 senior athletes performed an isometric mid-thigh pull, countermovement jump, repeated jump, and broad jump tests during a National Rugby League pre-season. The effects of age (junior vs. senior) and position (adjustables vs. hit-up forwards vs. outside backs) on test results were investigated using a two-way analysis of variance. Cohen’s d effect sizes (ES) and 95% confidence intervals were calculated for pairwise comparisons. Isometric mid-thigh pull absolute peak force was greater for senior players compared to junior players (ES=0.88, p<.05). Countermovement jump absolute peak power was greater for outside backs (ES=1.12) and hit-up forwards (ES=1.23) compared to adjustables (p<.05), greater for senior outside backs compared to junior outside backs (ES=1.53, p<.05), and greater for junior hit-up forwards compared to senior hit-up forwards (ES=1.00, p<.05). This research demonstrated the differences in strength and power of rugby league athletes between playing age and position.

Twenty-four anthropometric measures, defining the four latent morphological dimensions, were used.

Between wings and pivots no significant differences were found in longitudinal body dimensions; however, the measures of skeletal transversality, voluminosity and partially of fatty tissue (two variables) corroborated the fundamental difference between these two positions: pivotsʼ body built was more robust. No significant differences were found in longitudinal and almost all transversal measures between backs and wings; however, the differences in body voluminosity (all in favour of backs) were probably due to the selection process. In the juniorsʼ somatotype (3.72‒3.49‒2.32), endomorph and mesomorph components were predominant over the ectomorph component, in which the lowest values were obtained from the players in all the three positions. It is of outmost importance that handball practitioners should work on the reduction of players’ percentage of subcutaneous fatty tissue and on the enhancement of the portion of active muscle mass in their body composition by the implementation of quality sports training programmes and changes in dietary habits if better game performance and sports achievements of the Croatian junior female handball players are expected.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":"52 1","pages":"124-133"},"PeriodicalIF":1.2,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/k.52.1.10","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42355721","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}

Fifteen professional basketball players provided their wellness status and perceived training load for all training sessions and matches over a season. Daily correlations were based on the perceived load of a training session/match and the wellness status rated on the following day (before the next session). Weekly correlations were based on the sum of all ratings of the week for each variable. Results showed that DOMS and fatigue presented higher correlations with session-RPE than stress and sleep quality on both daily and weekly analyses. Daily measures presented small-to-moderate correlations between perceived training load and wellness categories over the months. Weekly correlations increased (moderate-to-large) for all wellness categories, except for stress. We concluded that DOMS and fatigue are more associated to session-RPE than stress and sleep quality in professional basketball players. Weekly analyses may help coaches to better understand the impact of training load on athletes’ physical wellness (DOMS and fatigue), possibly due to a delayed physiological response to training load. A daily assessment of stress may be helpful to identify training activities that negatively impact athletes’ wellness.","PeriodicalId":49943,"journal":{"name":"Kinesiology","volume":"52 1","pages":"151-156"},"PeriodicalIF":1.2,"publicationDate":"2020-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.26582/k.52.1.18","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49171257","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}
