{"title":"Sports injuries and psychological aspects of pain perception of athletes","authors":"Jakub Sciranka, Adriana Kaplánová","doi":"10.5507/ag.2021.021","DOIUrl":"https://doi.org/10.5507/ag.2021.021","url":null,"abstract":"Background: Injury is one of the risks of performing regular sports activities, which causes mild to severe physical discomfort and emotional distress for athletes. Objective: As there is not much research on the psychological aspects of pain perception of athletes, the main purpose of this study was to investigate differences in pain coping styles according to gender and type of sport. Methods: The sample consisted of 147 athletes (101 men, 46 women) who reported a previous sports-related injury, with an average age of 20.82 ± 1.61 years, involved in individual (n = 59) and team (n = 88) sports. The pain perception was evaluated by Sports Inventory for Pain (SIP15) comprised of three subscales: coping by direct action, catastrophizing, and somatic awareness. Results: We found that men perceive pain in sport more intensely and sensitively than women (p = .01, r = .21). Nevertheless, men consider pain to be more bearable and give up less than women (p = .05, r = .16). In individual and team sports, we did not find significant differences in response to painful stimuli, but in terms of giving up due to the perceived pain, the athletes of individual sports scored higher values than athletes of team sports (p = .04, r = .17). In coping by direct action, we also did not find significant differences between gender or types of sports. Conclusions: The results of our research suggest that pain perception is one of the factors influencing giving up in the sport. Therefore, we recommend that this aspect be considered in psychological preparation and that the efforts of sports psychologists should focus on eliminating escape reactions, especially for women, which would contribute to higher mental resilience and effective management of painful obstacles. We also recommend implementing psychological preparation aimed at overcoming pain more in individual sports, because it seems that individual athletes can handle pain much more difficultly than collective athletes.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47966040","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}

Objective: The aim of this study was to investigate the associations between VBT-variables derived during deadlift exercise executed at different loads and anthropometric variables, and vertical and horizontal jump performance in young athletes. Methods: Seventeen youth soccer players (16-18 years old) were included. Predictors were body height, body mass, body fat percentage, and VBT-variables (force, power, and velocity) measured at different loads (45%, 55%, 65%, 75%, 85%, and 95%) of a one-repetition maximum deadlift (1RM). Criteria included tests of vertical and horizontal jumping performance. Results: The VBT-variables are more strongly correlated with horizontal jumps (Pearson's r up to .81) than vertical jumps (Pearson's r up to .75). The VBT-variables for the deadlift recorded at lower loads stronger correlated with jumping performance than the VBT-variables recorded at higher loads. Conclusions: Results of the study suggest that light-to-moderate loads (45%-65% of 1RM) maximize power output and are therefore more strongly related to jumping performance in youth athletes. Further intervention studies aimed at the improvement of jumping performances using the VBT are warranted.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47364676","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}

In this way, research has been conducted using the active methodology Flipped Learning (FL) in all areas of Primary, Secondary and Higher Education. Objective: The current study aims to analyze the effect on student motivation after an intervention with the FL teaching technique, using a Parkour Didactic Unit in primary school students. Methods: One hundred students of 6th grade of Primary (11-12 years old) participated in this study, of which, 45 were girls and 55 were boys. It was randomly decided that 6oB and 6oD would follow the teaching styles that were already used in the center regularly (TRAD group) and otherwise, the 6oA and 6oC groups used FL teaching technique by watching videos created by the principal investigator for the present investigation (FLIP group). The Motivation Questionnaire in Physical Education in primary education and personal interview were applied before and after intervention. Results: The results showed an increase of intrinsic motivation (p < .001), identified motivation (p < .001) and introjected motivation (p < .001) in FLIP group. Moreover, external motivation, as well as the amotivation of the students, has decreased after the intervention. Regarding the TRAD group, a significant decrease in intrinsic motivation and identified motivation was observed. According to qualitative results, the most remarkable thing is that students consider FL as more fun, efficient, accepted and motivating. Conclusions: Intrinsic motivation increased significantly and amotivation values decrease in FL group. FL approach allows using more time in Physical Education classes and, consequently, it is perceived as more fun for the students.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44400804","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 tackle students' physical inactivity, reforms in higher education were supposed to reinvent physical education (PE) programs, revise their objectives and tasks. Nevertheless, European universities are experiencing a physical activity crisis, and recent generations of students are facing health problems due to underprovided levels of PA. Objective: The aim of this descriptive study was to analyze the state and status of physical education in higher education in selected European countries with regards to its curriculum and resources. Methods: Quantitative data were collected from 66 tertiary institutions from various countries in Europe. The questionnaire was used to gather information regarding characteristics of tertiary institutions, sport and leisure facilities, types and characteristics of PA programs available for students. Results: PE classes were obligatory in 44% and facultative in 30.3% of tertiary institutions; 22.7% of the institutions offered mixed PE curricula. The most popular team sports were volleyball, soccer and basketball, whereas fitness and functional training were the most popular types of individual PA. PE sessions lasted one or two semesters in 53% of the institutions. In 12% of establishments, PE was not part of curricula. In 60% of institutions, PE curricula consisted of 31-60 academic hours during the entire study program, and 55% of establishments charged additional fees for sports activities. In 55% of the analyzed institutions, physical fitness assessments were conducted only to determine students' eligibility to participate in team sports. Conclusions: The research study investigated problems of insufficient PA levels in higher education, indicating several reasons for this state of affairs. The study recommends that PE curricula are thoughtfully planned and executed with improved financing. Furthermore, PE ought to be combined with health education to promote active and healthy lifestyles among students.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42873279","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}

Objective: The main aim of this study was to cross-validate the Greek version of the Physical Activity Class Satisfaction Questionnaire (PACSQ) in a Greek educational context. The internal consistency of the PACSQ was also examined as well as the levels of satisfaction, gender, and grade of studies as factors that differentiate lesson satisfaction from lesson attendance. Methods: A total of 459 elementary school students (220 boys and 239 girls) aged between 11 and 12 years, across the country joined in the study. The Greek version of PACSQ was used. The statistical analysis included descriptive analysis, confirmatory factor analysis, reliability analysis and discriminant and convergent validity, and one-way multivariate analysis of variance. Results: The results of the confirmatory factor analysis demonstrated that the hypothesized model produced a significant χ2 (3311.55), normed fit index (.95) and comparative fit index (.96). The root mean square error of approximation (.62) was also considered to assess the degree of fit of the model. Composite reliability (≥ .879) and variance extracted (≥ .586) of all dimensions of the PACSQ demonstrated an acceptable reliability coefficient. Conclusions: From the analysis of the results, we came to the following conclusions. The PACSQ constitutes an instrument credible enough to measure the satisfaction of elementary school male and female students. Students seem to be quite satisfied by the cognitive process. Gender is a differentiation factor only as far as Normative Success is concerned. Students in the 6th grade (12 years old) appear to be more satisfied by their participatiοn in a physical education lesson.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70741806","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}

Objective: Based on a sample of competitive Czech beach volleyball players, this study aimed to assess the relationships among achievement goal orientations (task/ego), sport motivation (represented by intrinsic motivation, extrinsic regulation, and amotivation), and athletes’ competitive performance. Methods: A total of 128 beach volleyball players (63 men and 65 women, age 26 ± 6.27 years, range 14–42 years) from the highest Czech national competition participated in the questionnaire survey. The questionnaire battery included the Sport Motivation Scale-6 as a measure of self-determined sport motivation and the Perception of Success Questionnaire as a measure of achievement goal orientation. We used multiple linear regression models to assess the relationships among achievement goal orientations, different types of sports motivation, and athletes’ performance in sports competition measured by their point averages at the end of the season. Results: In regression models, we observed different effects of task and ego orientations on dependent variables, including intrinsic motivation, external regulation and athletes’ competitive performance. Specifically, we found a highly significant effect of task orientation in the model of intrinsic motivation (ß = .522, p < .001, R2 = .255) and a highly significant effect of ego orientation in the model of external regulation (ß = .394, p < .001, R2 = .132). Furthermore, we found a significant effect of ego orientation in the model of athletes’ competitive performance (ß = .239, p = .005, R2 = .122). Conclusions: We assume that task and ego orientations contribute to different outcomes in competitive athletes, with task orientation supporting athletes’ interest in and enjoyment of the sport and ego orientation supporting athletes’ external regulation and performance in competition. Based on self-determination theory, task orientation may affect intrinsic motivation through the satisfaction of the basic needs of autonomy, relatedness and competence. At the same time, ego orientation may support less self-determined motivation but may also represent an advantage in the highly competitive environment of elite sports.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70741728","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}

Objective: The purpose of this study was to assess the correlation between basic anthropometric parameters (body height and body weight) and jumping performance in a group of 16 female volleyball players (age 19.14 ± 5.52 years, height 1.80 ± 0.06 m, weight 69.81 ± 6.85 kg) and in a control group of 15 female university students (age 22.90 ± 0.83 years, height 1.70 ± 0.05 m, weight 61.70 ± 8.23 kg). Methods: The Quattro Jump 9290BA force platform system (Kistler, Winterthur, Switzerland) was used to test jumping performance in single vertical jumps (squat jump, countermovement jump) and 45-s continuous jumps. In single jumps, jump height was analysed and during the 45-s continuous jumps the maximal and mean jump height, the average contact time and the fatigue index were evaluated. The efficiency of the conversion of mechanical work into mechanical energy at the moment of takeoff was calculated. Results: No significant influence of body height and body weight was found in the jumping performance in the squat jump and countermovement jump. In continuous jumps, a significant correlation was found between body height and fatigue index in the volleyball players. In the control group, in most of the tests moderate correlation between body height and jump height was observed. In the volleyball players, rather low values of efficiency of take-off (23.67 ± 2.64%) were calculated. The values in the control group were even lower. Conclusions: Nowadays, many volleyball coaches choose individuals mainly according to body height, but it is important that the talent identification process should also consider jumping abilities in the simple jumps and in continuous jumps. All these parameters should help coaches choose the right players for the appropriate position and role in the team.","PeriodicalId":51894,"journal":{"name":"Acta Gymnica","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70741978","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}

Objective: The aim of the presented study was to examine the effects of the 4-week yoga-based intervention on balance, body composition and the mental health aspects of elderly men. Methods: 67-80-year-old elderly men (N = 234, mean age 72.5 ± 7.7 years) were assessed with The Tinetti Balance Assessment Tool, bioimpedance body composition analyser InBody 230 and the Health Survey SF-36, applied for the pre- and post-testing. The experimental group (n = 122) underwent the 4-week intervention based on yoga exercises, while the control group (n = 112) had a usual daily program at their senior homes or centers. Results: The yoga intervention led to significant improvement of both the static balance and gait scores compared to the control group, with medium effect size, ηp2 = .070 and .080. The intervention also had an effect on the decrease of body fat percentage (by 1.7%) and an increase in muscle mass (by 1.3 kg), with a large effect size, ηp2 = .214 and .301. Results of the Health Survey showed that overall mental health did not change significantly although positive improvement in two items connected with emotional problems.

This also applies to the younger generation, in other words, middle-aged urban professionals (muppies). Objective: The aim is evaluating whether yuppies and muppies can be a role model for society in the field of taking care of leisure-time physical activity (PA). Methods: Surveys were conducted by an Omnibus survey on the representative sample of Poles in two studies (N = 1053, N = 1067). Persons aged 20-39 (N = 762 were selected) and based on the criteria: education, residence in cities, study skills character of work, income, there was created a yuppie/muppie group (n = 67) and non-yuppies (n = 695).

So far, findings indicate modification role of sports activity and its type in terms of contact's occurrence, in the behavior of individuals. Objective: The aim of the study is to compare the level of the dimension of aggression and anxiety trait between nonathletes and contact and noncontact sport athletes and to assess the relationship between dimensions of aggression and the level of anxiety trait across the groups. Methods: The research group consisted of 153 males aged 22.07 ± 2.49 years: 47 contact sport athletes, 51 noncontact sport athletes and 55 nonathletes. Dimensions of aggression were evaluated by the Buss-Perry Aggression Questionnaire, anxiety trait was evaluated by the State-Trait Anxiety Inventory. The differences between the groups were assessed with the Kruskal-Wallis test and Mann-Whitney U test was used for posthoc pairwise comparisons. Relationship between dimensions of aggression and anxiety trait was assessed by the Spearman correlation coefficient. Results: We found that nonathletes were more physically aggressive than contact sport athletes and they also displayed a higher level of anger and hostility. Moreover, nonathletes were more hostile, physical and verbally aggressive than noncontact sport athletes. Nonathletes also had a higher level of anxiety trait than athletes. There was no difference between athletes in any dimension of aggression and anxiety trait level. Besides that, we found a significant relationship between anxiety trait level and physical aggression across the groups.
