Thus, the aim of this study was to quantify and compare the external loads imposed upon players during official Ultimate Frisbee matches according to sex. Material and methods: Twelve male and female players participated in four official Ultimate Frisbee matches. Players were divided according to sex (8 males and 4 females). Results: The average duration of matches was 62.3 ± 13.8 min, during which the players were active for 34.9 ± 11.4 min. External loads (i.e., total distance covered, distance covered at different speeds, accelerations and decelerations) encountered by Ultimate Frisbee players were compared between sexes (males vs females). Male players registered greater external loads (p < 0.05 large-moderate), especially performing high-intensity actions (distance at high intensity, distance at very-high speeds, and medium-high accelerations and decelerations) than female players. Conclusions: Coaching and performance staff should consider the sex of each player when developing training programmes and tactical strategies to optimise player performance during Ultimate Frisbee matches.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"1 1","pages":"4-11"},"PeriodicalIF":0.5,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82935453","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 addition, it was also intended to investigate the magnitude of the correlations between some specific variables (i.e., height, weight and wingspan) and the swimming performance. All participants were analyzed, regarding their anthropometric characteristics and their performance in the 50m and 400m freestyle swim. A total of 98 swimmers aged between 11-13 years old (mean ± standard deviation: 12.63 ± 0.76 years of age, 1.59 ± 0.08m height, 47.11 ± 7.82kg body weight) participated in the study. The results suggest that anthropometric characteristics have a positive relationship in the performance of swimmers when comparing genders (p< 0,01), furthermore positive linear correlations was found in height (r = 0.305 and r = 0.253, p <0.01), weight (r = 0.202 and r = 0.140, p <0.01), and wingspan (r = 0.227 and r = 0.203, p < 0.01) for 50m and 400m freestyle swim. The swimmers’ efficiency of segmental movements was related to anthropometric characteristics and strongly associated with the length of the swimmers’ segments. These results may be due to the fact that swimmers’ maturational status may have played an important role, in the observed results. In addition, when comparing genders, the height and weight values of male swimmers tended to be higher. Furthermore, the differences observed in the 50m and 400m freestyle swimming events were related to the relationship that anthropometric characteristics have on the biomechanical parameters of swimming, which influence swimming performance. This study concluded that the improvement of performance of each young national-level swimmer is strongly related to the rate of growth, development and maturation.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"36 1","pages":"12-25"},"PeriodicalIF":0.5,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76838396","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}

Purpose: To examine the impact of using the XPO Trainer on neuromuscular activation time at low and high speeds in young, seemingly healthy adults. Materials and Methods: This study consisted of 36 healthy adults (age: 24.6±3.9 years). Each participant wore surface electromyography (EMG) electrodes on their dominant leg over the anterior tibialis and gastrocnemius (GA). The four tasks examined in this work were, walk, run, walk pushing (WP) and run pushing (RP). Participants were asked to walk on their self-selected speed. To execute the tasks, participants walked and ran a distance of 40 feet both with and without the XPO Trainer sled. Subjects completed a total of 3 trials per task (total of 12) with one-minute breaks between tasks to reduce fatigue. Results: Neuromuscular time for activation was significantly modified while pushing the sled in both self-selected speeds, particularly in GA muscle. WP and RP exhibited an inverted relationship in neuromuscular timing patterns. Conclusion/Clinical Relevance: We suggest using the sled while walking to provoke endurance and running to work on strengthening of lower leg musculature. The sled proved to be a useful adjunct tool for neuromuscular training in different alterations of the lower limb muscles, especially the extensor musculature.","PeriodicalId":36150,"journal":{"name":"European Journal of Human Movement","volume":"76 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83866841","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}
