Participants were eight boccia athletes (cerebral palsy, cervical spinal cord injury, muscular dystrophy, spinal muscle atrophy) in whom throwing distance, ranges of motion at the shoulder joint, elbow joint and wrist joint and upper limb muscle strength were measured. Throwing distance was measured to the point where the ball landed so to remove any effect of the floor. Upper limb muscle strength was measured by isometric contraction using a handheld dynamometer. No correlation was found between throwing distance and range of motion of the shoulder joint, but correlations were found between throwing distance and strength of shoulder flexors (r = 0.76, p < .05), shoulder abductors (r = 0.84, p < .01), and elbow flexors (r = 0.77, p < .05). Active training to improve muscle strength around the shoulder joint, regardless of the underlying disease, was considered likely to lead to improvements in competitiveness. Due to the severe dysfunction of boccia athletes, training methods are often restricted. Verification of more effective training methods is needed while managing risks according to the physical function of the athlete and the type of disability.","PeriodicalId":224249,"journal":{"name":"Scientific Journal of Sport and Performance","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129815658","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}

During ten official matches 23 elite footballers were tracked using GPS devices. Metrics per minute (m·min-1) as well as absolute variables: total distance (TD), high-speed running distance (HSRD > 19.8 km·h-1), sprint distance (SD > 25.2 km·h-1), relative high-speed running distance (VelB4), relative sprint distance (VelB5), acceleration distance (AccB3 Dist, distance with variations in running speed > 3 m·s-2), the number of high-intensity accelerations (HI Acc > 3 m·s-2) and decelerations (HI Dec > 3 m·s-2) were quantified. Significant effects of 15min blocks were found for TD (m) (p < .001; ES = .078), TD (m·min-1) (p = .047; ES = .036), HSRD (m) (p = .033; ES = .039), VelB4 (m) (p < .001; ES = .132), and HI Dec (n·min-1) (p = .002; ES = .059). Transitional activities recovery period was found to be 108.5 ± 26.2 s, CTA recovery period was 25.7 ± 3.6 s, while CTA peak duration reached 53.3 ± 18.2 s. This study indicates that physical metrics decrease in the last 15min blocks during transitions and high-pressure activities in games. In conclusion, repeated high intensity / high velocity activities frequently occur during contextualized peak intensity periods (transitions) in football, which should be reflected in modern training design.","PeriodicalId":224249,"journal":{"name":"Scientific Journal of Sport and Performance","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127254040","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}

GPS technology was used to analyse the movement demands of 45 AF players from the same AFL club during 43 matches across the 2019 and 2020 seasons. GPS data were categorised into measures of volume (total match time [TMT] and total distance [TD]) and intensity (metres per minute [m.min-1], high-intensity running [HIR] distance and m.min-1 [>17 km·h-1], and very-high intensity running [VHIR] distance and m.min-1 [>23 km·h-1]). Volume decreased in 2020 with reductions in TMT (effect size [ES] ± 95% confidence interval [CI] = -1.8 ± 0.2; p < .001) and TD (ES = -1.8 ± 0.2; p < .001) overall, across all positional groups, and quarters. Intensity increased, evidenced by increases in HIR m.min-1 (ES = 0.3 ± 0.1; p < .001), and VHIR m.min-1 (ES = 0.3 ± 0.2; p = .006). HIR m.min-1 increased for midfielders (ES = 0.6 ± 0.3; p = .017). Defenders exhibited increases in HIR m.min-1 (ES = 0.2 ± 0.2; p = .007), and VHIR m.min-1 (ES = 0.4 ± 0.2; p = .010). Intensity of third quarters decreased at a greater rate in 2020 with reductions in m.min-1 (ES = -0.2 ± 0.1; p = .004) and HIR m.min-1 (ES = -0.2 ± 0.1; p = .037) compared to Q1. Systematic reductions in volume were found overall, across positional groups, and quarters. Average movement speed remained relatively stable overall, across quarters and positional groups. Increases in intensity were defined predominately by increases at high and very-high intensity speeds per minute, with defenders exhibiting the greatest increase in intensity and change to their match activity profiles. Longer quarter and three-quarter time breaks, and time between goals preserved intensity.","PeriodicalId":224249,"journal":{"name":"Scientific Journal of Sport and Performance","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131316962","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}

Whole-body electromyostimulation (WB-EMS) is a time-efficient training method that could be used as an adequate training intervention for different persons due to the intensive, involuntary contraction of the musculature and the resulting increases in muscular performance. Therefore, the aim of the study was to investigate if WB-EMS has positive effects on body composition and physical performance parameters of individuals of different age decades. Subjects from age decades 20-80 years participated in a 24-week WB-EMS training intervention. PRE and POST diagnostics of trunk extension and flexion, knee extension and flexion, hand grip strength, skeletal muscle mass (SMM) and body fat were performed on three consecutive days and the daily maximum values were summarized as the total mean value and were used for the descriptive data interpretation. Strength parameters were summarized in an unweighted additive index, the muscular change index (MCI). Regarding the results obtained by using the MCI, remarkable increases were observed in participants from all decades (20: +12.02%; 30: +6.59%; 40: +6.85%; 50: +3.96%; 60: +10.95%; 70: +20.26%; 80: +20.86%). Therefore, WB-EMS seems to be a time-efficient and adequate form of training that can be conducted to enhance muscular performance at different ages.","PeriodicalId":224249,"journal":{"name":"Scientific Journal of Sport and Performance","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133483108","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 current investigation was a parallel-group design that collated data from a cohort of 19 male outfield players from an elite European soccer team (mean ± SD, age 26 ± 4 years; weight 80.5 ± 8.1 kg; height 1.83 ± 0.07 m; body-fat 10.8 ± 0.7%). Players were classified and matched by position and grouped accordingly: centre defender (CD) n = 5, wide defender (WD) n = 3, centre midfield (CM) n = 7, wide forward (WF) n = 2, and centre forward (CF) n = 2. For all performance variables, the mean values were compared in caffeine consumers vs. non consumers using independent-sample t-tests, with significance set at p < .05. Cohen’s d was used to quantify the effect size, and was interpreted as trivial (<0.2), small (0.2-0.5), medium (0.5-0.8), and large (>0.8). For all examined variables, there were trivial or small non-significant (p > .05) trivial or small differences between caffeine consumers and non-consumers. The findings of the present research did not confirm the study hypothesis, once running and accelerometry-based variables did not improve with the caffeine ingestion of 150 mg. Therefore, the caffeine supplement used in this study is not suggested for improving performance in the variables analysed.","PeriodicalId":224249,"journal":{"name":"Scientific Journal of Sport and Performance","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127372304","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}
