The test included jump or dive into deep water, swim 100 m on the front, stop and rest 3 min front and back, swim 100 m on the back and climb out over edge of pool. Each skill was scored from 0 to 2.0, a perfect score being 12.0. The Wilcoxen Signed Rank test was used to test the significance of the difference between treatments. Total scores with and without outer clothing were correlated using the Spearman rho.\u0000 \u0000 \u0000 \u0000 The average total scores were 10.65 without outer clothing and 8.55 with (of 12.0). The Wilcoxen Z score was 2.79, statistically significant at p = 0.005. The Spearman rho between the two scores was 0.41. Of those who were judged able to swim without outer clothing, a significant number were judged unable to swim with outer clothing. This was true at whatever level “can swim” was arbitrarily placed. Among those who scored best, the difference between without and with clothing was considerably less than among those who scored poorly.\u0000 \u0000 \u0000 \u0000 The added burden of clothing significantly affected skill performance.

Participants (N= 174) completed a pre-intervention survey that sought information on their water competency, open water experience, previous instruction, and perceptions of drowning risk.In terms of risk appraisal processes, more females, Asian peoples, and those with lower self-reported swimming and rescue competency perceived greater severity of drowning risk and greater vulnerability to that risk when swimming in open water. In terms of coping appraisal processes, males, non-Asian peoples and those with self-reported good swimming and rescue competencies were more likely to report confidence in the self-efficacy of their preventive actions.Considerable variations in risk (threat) appraisal and coping appraisal processes in respect of the risk of drowning were evident. The implications of the findings on water safety education are discussed. Ways of promoting water safety and drowning prevention are examined and recommendations for future research studies to address limitations of the study are made.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48267998","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 aim of the present study was to investigate the velocity decrement of several life-saving, self-rescue and rescue related strokes when introducing waves of different heights.Thirty-three subjects swam twelve 25m sprints each, in a randomized order, in a 3x4 (wave height x stroke) design. The wave heights were flat, medium (ca 20 cm) or large (ca 40 cm), in a specially designed wave-simulating pool. The strokes studied were front crawl, head-up crawl, back crawl and breaststroke. A subgroup swam front crawl, head-up crawl and head-up crawl with fins. A repeated measures ANOVA showed a significant effect of stroke, F(3,23)=108 (p<0.001), showing that these four strokes have different levels of performance; and wave height F(2,24)=87 (p<0.001), showing that introducing waves reduced velocity, but there was no interaction effect. The fastest stroke in flat water was not surprisingly, front crawl, followed by head-up crawl, back crawl and breaststroke. When introducing medium or large waves, the order of strokes from fastest to slowest was identical to flat-water conditions. The average velocity decrement when introducing medium and large waves was 3% and 7% respectively. For the subgroup swimming with fins, this was the fastest stroke, followed by front crawl, and head-up crawl. This order did not change when introducing waves, and the velocity decrement was 4 and 2% for medium and large waves respectively (not significantly different from other strokes).The conclusion is that the rank order of strokes does not change when introducing waves and that no stroke seems to perform relatively better in unsteady water compared to flat water. Other aspects than performance and velocity should be considered when choosing strokes for swimming in waves, these are discussed in the paper.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46116246","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}

While reviews on performance indicators in football are available, none focuses solely on the identification of success factors and addresses the large and growing body of recent research up until 2016.To find out what determines success in football and to organize the body of literature, a systematic literature review analyzing existing studies with regard to success factors in football was undertaken.The studies included in this review had to deal with performance indicators related to success in football. The studies were published in 2016 or before. The initial search revealed 19,161 articles. Finally, sixty-eight articles were included in this review. The studies were clustered with regard to comparative analyses, predictive analyses and analyses of home advantage.In total, 76 different variables were investigated in the reviewed papers. It appeared that the most significant variables are efficiency (number of goals divided by the number of shots), shots on goal, ball possession, pass accuracy/successful passes as well as the quality of opponent and match location. Moreover, new statistical methods were used to reveal interactions among these variables such as discriminant analysis, factor analysis and regression analysis. The studies showed methodological deficits such as clear operational definitions of investigated variables and small sample sizes.The review allows a comprehensive identification of critical success factors in football and sheds light on utilized methodological approaches. Future research should consider precise operational definitions of the investigated variables, adequate sample sizes and the involvement of situational variables as well as their interaction.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41973904","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}

However, more objective parameters, like thermal images, have been researched to determine, along algometry, valid parameters. Objective : The aim of this study was to analyze the thermal differences and the painful sensibility between the knees (with SOS and contralateral) of young soccer players. Methods : 6 young men, aged between 12 and 15, members of football schools, composed the sample. Images were taken from an anterior view of both knees, with the volunteer in a seated position, the knees flexed at 90o degrees and both feet flat on the floor. After the thermal image capture, the patients were submitted to an evaluation with the pressure algometer. Results : According to the results, it was found that the knee affected by the OSD showed temperatures significantly higher than the contralateral (p = 0.027) and also greater sensitivity to the pressure algometry (p = 0.027). Conclusion : it can be concluded that the inflammatory process, during OS Syndrome, promotes a local thermal hyper-radiation, identified with the high sensitive thermographic infrared image, producing a significant difference in local temperature between the knees of a single individual. Moreover, this process also increases the pain sensibility, accessed by pressure algometry.","PeriodicalId":38865,"journal":{"name":"Open Sports Sciences Journal","volume":"10 1","pages":"223-228"},"PeriodicalIF":0.0,"publicationDate":"2017-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49491857","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}
