The results of the two-factor ANOVA indicate that aquatic competence values increase from the lowest to the highest age group and the values found for the different levels of experience in swimming lessons. A regression model was applied and proved to be significant. According to the model, age and previous aquatic experience together were responsible for explaining 46% of the variance in aquatic competence. When applied in each group, the regression analysis indicated that age starts to exert less influence and the experience a greater influence on aquatic competence the older the age groups become. In addition, as the experience increases, the difference in aquatic competence increases between older and younger children. Therefore, the analysis of the contribution of these variables allows professionals to be guided in planning teaching strategies for the development of aquatic competence.\u0000Keywords: constraints, children, aquatic competence.","PeriodicalId":53589,"journal":{"name":"Motricidade","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46428005","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}

Therefore, this study aimed to determine the reliability of the handheld dynamometer in the measurement of maximum voluntary isometric contraction of trunk extensors in healthy adults. Twenty-six healthy adults of both sexes (21.53± 1.88 years old) performed the test and retest with a 1-week interval. The comparison between test-retest demonstrated high and very high intraclass correlation coefficient for peak strength (0.82; 0.60 to 0.92) and mean strength (0.90; 0.76 to 0.95), respectively. Also, the Bland-Altman analyses indicate an error of 5.10 kg for peak strength and 5.7 kg for mean strength. In addition, the minimum detectable change for peak strength was 6.03kg (16.18%) and 5.92 kg for mean strength (20.95%). In conclusion, the test presents high reliability for the extensor muscles of the trunk in healthy adults.

Furthermore, the motor symptoms are typically unilateral, with the onset side often remaining more affected throughout the disease course. Therefore, as Parkinson's disease is an idiopathic disease, several questions are raised, one of them how the disease affects each person differently. For example, a person can be right-handed for the upper limb and left-footed for the lower limb, which can change strength scores. Thus, the aim of the study was to investigate the differences in muscle strength in people with Parkinson's disease, right-handed for upper limb and right-footed for lower limb, that have one most affected side, right or left side, on the upper and lower body. The sample consisted of 26 individuals diagnosed with Parkinson's disease, right-handed for the upper limb and right-footed for the lower limb. Subjects needed to visit the laboratory one time to assess handgrip and knee extensors strength. There were no differences between sides in upper limbs affected by the disease, and there were no differences between sides in lower limbs affected by the disease, p > 0.05. There were no differences in strength between sides of the same body part affected by the disease. To say that people affected on the determined side are weaker than others may be a misconception since Parkinson's disease is idiopathic.\u0000Keywords: handgrip; isokinetic; Hoehn & Yard; handedness; substantia nigra","PeriodicalId":53589,"journal":{"name":"Motricidade","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48672807","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}

Even though all the hiccups, constraints, and challenges imposed by the COVID-19 pandemic, the Games were successfully held in August 2021. For the first time in history, Team Portugal won four medals (one gold, one silver, and two bronzes). In 2018 the Portuguese Olympic Committee signed a contract with the Portuguese Institute of Sport and Youth (i.e., Portuguese government) listing the deliverables of the mission Tokyo 2020 against a funding scheme of 18.5 million euros (Contrato n.o 33-A/2018; Contrato -Programa de Desenvolvimento Desportivo n.o CP/1/DDF/2018). The document sets, among other goals and deliverables, that no less than two medals would be won at Tokyo 2020 (section IV.1. of the contract). \u0000On the road to Tokyo, Portugal got more than two medallists at World Championships in several Olympic sports. Indeed, there were six to eight potential medallists at the 2020 Olympic Games (O Jogo, 2021). There is evidence that just one-third to one-fourth of the Olympic athletes are able to excel and outperform at the Olympic Games. In the sport of competitive swimming, just 29.82% of all male Olympians and 53.84% of the finalists at Rio 2016 improved their entry times (Barbosa, 2016a). On average, only 30% of the swimmers were able to improve their entry time at the 2012 and 2016 Olympic Games (Barbosa, 2016b). At Rio 2016, Team Portugal was expected to win two medals out of nine potential medallists, i.e., almost 25% of effectiveness (Garcia, 2016). Thus, one can wonder if the Portuguese Olympic Committee was sensible, assuming that two athletes would reach the podium spot out of six to eight potential medallists. Also, it begs the question if the four medals won were an outstanding achievement, deemed as a substantial improvement of the Portuguese sports system or, if alternatively, the Portuguese Olympic Committee underestimated the number of medals that the country could win.","PeriodicalId":53589,"journal":{"name":"Motricidade","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43633273","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}
