Objective: The aim of the study was to assess diet quality indices among Polish and Spanish physical education students depending on country of residence and gender. Materials and methods: Research was carried out among 219 students from Poland and 280 from Spain. A questionnaire was used to evaluate views on eating and nutritional habits (Kom-PAN). Based on the daily frequency of consuming specific groups of products, 2 indices were calculated: the pro-healthy diet index (pHDI-10) and non-healthy diet index (nHDI-14). Two-way ANOVA was used for statistical analysis. The level of significance was set at p=0.05. Results: The values of the pro-healthy (pHDI-10) and non-healthy diet (nHDI-14) indices in the group of students were 4.65 and 4.05 (times/day), respectively, which means a low level of both favourable and unfavourable food choices. Students from Poland, regardless of gender, showed a higher level of eating a healthy diet (pHDI-10) than students from Spain. However, the level of the non-healthy diet index (nHDI-14) between students from Poland and Spain differed by gender (p<0.001). In the Polish group, men obtained a higher nHDI-14 index than women (p<0.001), while in Spain, these values were at the same level. Furthermore, it was found that differences between countries occurred only in men, with students from Poland obtaining higher values of the nonhealthy diet index (nHDI-14) than those from Spain (p<0.001), while students from both countries demonstrated similar values. Conclusions: Low levels of healthy and unhealthy diet indices were demonstrated in Polish and Spanish physical education students, with the quality of diet differentiated by country and gender.","PeriodicalId":223482,"journal":{"name":"Journal of Kinesiology and Exercise Sciences","volume":" 861","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141127546","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}

Lower limb injuries are a common problem for soccer referees and have a negative impact on their performance in a match. The purpose of the study was to assess the explosive power and dynamic stability of soccer referees from the viewpoint of refereeing function. Methods: The research sample consisted of 26 soccer referees, including 13 head referees and 13 assistant referees. The following jump tests were administered to determine the referees’ lower limb explosive power: the countermovement jump test (CMJ), the countermovement jump test with free arms (CMJ FA), the squat jump (SJ), and a 10-second vertical jump test. The level of dynamic stability was diagnosed by the Y Balance test. Results: Compared to assistant referees, head referees reached higher levels of explosive power in all measured parameters but the differences were not statistically significant. For the level of dynamic stability, we observed significant differences in the composite score and % lower limb length in favor of the referees in the posteromedial and posterolateral directions for the left and right legs. Conclusions: The greatest differences were found in dynamic stability, specifically in the composite score and % lower limb length in the posteromedial and posterolateral direction. The differences may be caused by typical movement patterns associated with these two adjudicatory roles. We recommend the inclusion of compensatory exercises in the training of assistant referees.","PeriodicalId":223482,"journal":{"name":"Journal of Kinesiology and Exercise Sciences","volume":"43 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139602869","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 human body begins to adapt its functioning to the conditions of hypobaric hypoxia in order to maintain homeostasis. Its disturbance can lead to respiratory failure, pulmonary, or cerebral oedema, and, consequently, death. The best method of AMS prevention is slow acclimatization. A high-carbohydrate diet, thermal protection, and pharmacological agents could be listed as additional prevention measures. The development of AMS is influenced by many factors such as ambient temperature, wind speed, altitude, physical preparation of participants, and appropriate protection against adverse effects of these factors. Nevertheless, both dehydration and overhydration may worsen the AMS symptoms. The body’s exposure to altitude and dehydration alone reduces aerobic performance. Appropriate hydration throughout a climb is necessary due to both intense physical exercise and a hypoxic environment.","PeriodicalId":223482,"journal":{"name":"Journal of Kinesiology and Exercise Sciences","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116525776","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}

Type A personality pattern (TAPP) is related to, among others, strong rivalry and struggle for achievements, which are features that fit into sports competition. One of the determinants of sports success is a proper diet.

The study was conducted among 165 high-level basketball players. An author-designed nutritional behaviour questionnaire (according to the recommendations of the Food Pyramid for Swiss Athletes) and the Framingham Score in the Polish adaptation were used. Spearman's rank correlation and the Mann-Whitney U tests were applied for the analysis of the results. Results. The study confirmed that along with the increase in TAPP, the healthy eating behaviour index among basketball players increased, although it did not reach the level of statistical significance (p=0.080). Comparison of TAPP levels between groups that adhered to or disregarded particular nutritional recommendations showed that athletes limiting the consumption of non-recommended products (sweetened carbonated and non-carbonated beverages, energy drinks, fast food, and sweet and salty snacks) demonstrated a higher level of type A behaviours than those who did not follow these recommendations (p<0.001). At the same time, however, athletes consuming fish at the recommended frequency and taking care of adequate hydration during training had lower levels of TAPP than those who did not follow these recommendations (p<0.05).

The aim of this study is to analyse present the effect of high heels on the distribution of foot forces on the ground in adult women attending high-heels dance classes. Material and Methods: The distribution of foot forces on the ground and the body balance of HHS female students before and after the training session were investigated. Foot arch measurements were taken using EPSR1 mats (Letsens Group, Letsens S.R.L. Via Buozzi, CastelMaggiore; Bologna, Italy). Results: The foot arch test showed that the entire study population had highly arched left feet (mean arched level of 8.85%) and right feet (3.70%). Analysis of the data showed that training in high heels reduced the longitudinal arch of the right foot (p=0.04942) by increasing metatarsal pressure. Pressure on the heel of the right foot decreased (p=0.017621). Statistical analysis of the stabilographic measurements showed statistically significant changes only in the distance from the centre of pressure before and after the test (p=0.047531).
