The purpose of this study was to examine the relationship between throwing distance, shoulder joint range of motion and upper limb muscle strength in boccia athletes. 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.
摘要本研究旨在探讨铁球运动员投掷距离、肩关节活动范围与上肢肌肉力量的关系。研究对象为8名脑瘫、颈脊髓损伤、肌萎缩症、脊髓肌萎缩症运动员，测量他们的投掷距离、肩关节、肘关节、手腕关节的运动范围和上肢肌肉力量。投掷距离被测量到球落地的点，以消除地板的任何影响。上肢肌肉力量用手持式测力仪等距收缩测量。投掷距离与肩关节活动度无相关性，但投掷距离与肩屈肌力量(r = 0.76, p < 0.05)、肩外展肌(r = 0.84, p < 0.01)、肘关节屈肌(r = 0.77, p < 0.05)有相关性。积极训练以提高肩关节周围的肌肉力量，而不考虑潜在的疾病，被认为可能导致竞争力的提高。由于地球运动员功能障碍严重，训练方法往往受到限制。需要验证更有效的训练方法，同时根据运动员的身体功能和残疾类型管理风险。

The aim of the study was to examine whether and to what extent increased levels of pressure affect the performance quality of the world’s top darts players. This investigation contributes to the understanding of the psychological factors that influence performance in professional darts and in professional sports overall. Data was collected from over sixty professional tournaments held over a period of two years. The players were divided into 5 groups based on the quality of their performance during the studied period. The point values were divided into 7 groups, where the criterion was the difficulty of finishing the leg at a given score. The level of pressure was primarily determined by the opponent’s score situation in a given moment. Data analysis using statistical methods such as tests of proportions and the Cochran-Armitage test did not indicate any statistically significant impacts of pressure on performance among professional players – neither positive nor negative. The results indicate a high level of mental resilience among professional darts players.

The aims of this study were to investigate the effect of 15min blocks on physical metrics during transitions, analyse frequency, type, duration, and recovery period between clusters of transitional activities (CTA) in elite football. 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.

Assess the influence of a 20% reduction in game time on the volume and intensity of elite AF players’ match activity profiles. 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.

Training and practice preparation have long received attention as the largest factors for injury prevention. While proper training and practice programs are a crucial component of injury prevention, they only represent a piece of a larger puzzle. External factors outside of training and practice such as sleep, nutrition, hydration, and rest are equally important for injury prevention due to athletes spending a majority of their day outside of their sport. These external factors have been shown to have powerful effects relating to injury epidemiology. They have also been shown to have major effects on the body’s autonomic and hormonal regulation systems. Due to athletes spending a majority of their day outside of training and practice, it is necessary that equal importance be given to external factors outside of sport, especially in regards to sleep, nutrition, hydration, and rest for optimal injury prevention strategies.

Lifelong fitness training plays an essential role in building and maintaining health. 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.

This systematic review and meta-analysis evaluated the validity of tests / markers of athletic readiness to predict physical performance in elite team and individual sport athletes. Ovid MEDLINE, Embase, Emcare, Scopus and SPORT Discus databases were searched from inception until 15 March 2023. Included articles examined physiological and psychological tests / markers of athletic readiness prior to a physical performance measure. 165 studies were included in the systematic review and 27 studies included in the meta-analysis. 20 markers / tests of athletic readiness were identified, of which five were meta-analysed. Countermovement jump (CMJ) jump height had a large correlation with improved 10m sprint speed / time (r = 0.69; p = .00), but not maximal velocity (r = 0.46; p = .57). Non-significant correlations were observed for peak power (r = 0.13; p = .87) and jump height (r = 0.70; p = .17) from squat jump, and 10m sprint speed / time. CMJ jump height (r = 0.38; p = .41) and salivary cortisol (r = -0.01; p = .99) did not correlate with total distance. Sub-maximal exercise heart rate (r = -0.65; p = .47) and heart rate variability (r = 0.66; p = .31) did not correlate with Yo-Yo Intermittent Recovery Test 1 performance. No correlation was observed between blood C-reactive protein and competition load (r = 0.33; p = .89). CMJ jump height can predict sprint and acceleration qualities in elite athletes. The validity of the other readiness tests / markers meta-analysed warrants further investigation.

At present, MOOCs have gradually become a part of daily teaching in colleges and universities, but domestic physical education curriculum research has not yet covered the content of the relationship between college students' learning self-regulation, self-efficacy, and physical education performance in the MOOC learning environment. Therefore, it is necessary to study the correlation between self-regulation and self-efficacy in the study of physical education MOOCs through a questionnaire survey and analysis of 52 college students majoring in physical education at a BSU university in Beijing. The study found that there is a significant correlation between self-regulation and academic performance, but the impact of self-efficacy on academic performance is not significant, and the relationship between self-regulation and self-efficacy needs to be further explored.

The present study examined the effect of acute caffeine ingestion (150 mg) on the physical performance of elite European soccer players during official competitive match-play. 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.
目前的研究考察了在正式比赛中，急性咖啡因摄入(150毫克)对欧洲优秀足球运动员身体表现的影响。本研究采用平行组设计，整理了来自欧洲一支精英足球队的19名男性外场球员的数据(平均±标准差，年龄26±4岁;重量80.5±8.1 kg;高度1.83±0.07 m;体脂10.8±0.7%)。球员按位置进行分类和匹配，分组为:中卫(CD) n = 5，边后卫(WD) n = 3，中前卫(CM) n = 7，边锋(WF) n = 2，中锋(CF) n = 2。对于所有表现变量，使用独立样本t检验比较咖啡因消费者与非咖啡因消费者的平均值，显著性设置为p < 0.05。Cohen’s d用于量化效应大小，并被解释为微不足道(0.8)。对于所有被检查的变量，咖啡因消费者和非咖啡因消费者之间的差异微不足道或微不足道(p > 0.05)。目前的研究结果并没有证实研究假设，一旦跑步和基于加速度的变量并没有随着摄入150毫克咖啡因而改善。因此，在分析的变量中，本研究中使用的咖啡因补充剂不建议用于提高表现。

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.

Walking and balance alterations are critical to address in older adults living with Parkinson's Disease (PD). These alterations negatively impact activities of daily life, decrease the quality of life and increase the risk of falls. Objective: Analyse the effectiveness of different long-term exercise interventions to improve walking and balance parameters in people aged over 60 years with PD. Methods: Experimental studies from the last 10 years collected from 5 databases (PEDro, PubMed, WOS and EBSCO) were analysed. PEDro scale was used to analyse the quality of the studies, and the result shown in the studies was contrasted with the minimal detectable change (MDC). Results: From 413 studies, a total of 7 RCTs and 2 pilot studies were included in the analysis. The range of age was 65.8 ± 10.7 and 73.59 ± 7.93 years. The duration of the disease was 5 to 15 years. The methodological quality ranged from "good" to "excellent". Conclusions: More significant clinical effect in PD population was obtained after interventions that included: high-intensity strength training, progressive increase of resistance, aerobic exercise, and walking and balance training.
