The aim of this study was to describe the knowledge, attitudes and tackle training practices of women's rugby coaches in relation to tackle safety and performance. A globally distributed online survey exploring coaches’ knowledge, attitudes and practices towards tackling women's rugby was completed by 357 coaches (mean age 41 ± 0.6 years) from 58 countries. The cross-sectional survey was distributed from March 2023 to June 2023. Survey development was guided by the Health Action Process Approach and informed by coaching experts, research evidence synthesis, and guidelines for international tackle safety programmes. Coaches believed that the risk of tackle injury in women's rugby is high and that proper tackle technique for safety is very important. More than 75% of coaches had never completed a tackle-specific training course, with only 39% aware of the availability of such courses. Time spent on controlled-contact and full-contact activities varied from 0 to 40+ min per week, averaging 10–20 min for both types of training. Barriers to the effectiveness of tackle training related to sociocultural factors, coach knowledge gaps, training environments, and player training considerations. Coach education, improved infrastructures, and physical development were ranked the highest priorities for improving tackle safety and performance. These findings inform future implementation strategies for tackle safety and performance in the context of women's rugby, highlighting the need to involve coaches in providing practical solutions, and the role of education and institutional/organisational support in facilitating such improvements.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"68 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In athlete selection, coaches play the role of decision-makers in selecting the most suitable athletes for a specific sport or competition from a large pool of talented athletes. Therefore, understanding how coaches’ decisions impact athlete selection is crucial in establishing selection rules, formulating effective decision-making, and developing accurate athlete development policies. This review was conducted by searching the Web of Science, PubMed, Scopus, and SPORTDiscus databases for English-language literature on coaching decision-making and talent selection, and screening and categorizing the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 10 articles were included in this review. Based on the meta-synthesis findings, coaches’ decision-making styles, intuition, and abilities play a significant role in athlete selection. Additionally, coaches’ personalities are also an important factor that influences their decision-making process in identifying and selecting talented players. This review also emphasizes that coach decision-making is essential not only in athlete selection, but also in athlete detection, identification, and development, as coach behavior affects the success of the entire team. In addition, reinforcement of professional competence development and maintenance of continuous learning for coaches is the requirement of the times and the key to the success of athlete selection.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"42 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic search of electronic databases was conducted. Meta-analysis was used to examine effects of trainings with different VL thresholds and used meta-regression to examine the interaction effects (correlation) between training effects and VL in different performance-based outcomes. Our systematic search yielded 1017 articles, 13 of which were included in the present study. Meta-analysis revealed that resistance training with both low (0%–20%) and high (30%–45%) VL thresholds improved squat strength, HLSV, LLSV, and CMJ height, but only low VL improved ST ( p < 0.05). Training gains for HLSV, LLSV, CMJ ( p = 0.088), and ST with low VL were superior to those with high VL ( p < 0.05). Meta-regression revealed that CMJ ( p = 0.076) and ST ( p = 0.010) demonstrated improvements as VL decreased in the range of 0% to 45%. In conclusion, squat resistance training with low (≤20%) VL provides relatively more effective training stimuli, improving performance in power and speed tasks. Optimal VL ranges may be in the range 10% to 20%, ≤20%, and ≤10% for the HLSV and LLSV, CMJ, and ST, respectively.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"118 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined how ball mass influences distance thrown. Based on geometric scaling principles a relationship was derived between ball mass and throw distance: throw distance was inversely proportional to ball mass. This relationship was tested in two ways. The first approach was using athlete shot put throw distances with different shot masses, and hammer throws performed with different mass hammers. These experimental data were better represented by the non-linear relationship, derived from geometric scaling principles, than assuming a simple linear relationship. The second approach was to use a simulation model to predict throw distance for balls of different masses. The model contained realistic segmental inertial properties, activation dynamics, moment-joint angle properties, and moment-joint angular velocity properties. The non-linear relationship provided a better fit to the results of the simulations compared with a linear model. The experimental and modeling results support the theoretical relationship derived between distance thrown and ball mass. The relationship has utility for coaches monitoring and planning the training of athletes which incorporates throwing different mass balls.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"28 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140611646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following a systematic search across four databases (PubMed, CINAHL, SPORTDiscus, and Cochrane Library), a total of 22 articles were included. The findings indicate that there was a significant correlation between the stability of hold component, as measured by DEV_X ( r = −0.60; 95% confidence interval (CI) = −0.69 to −0.49; p < 0.001) and HITf ( r = 0.69; 95% CI = 0.56 to 0.79; p < 0.001) and shooting performance in both shooting disciplines. In addition, HITr, another stability component, revealed a significant positive correlation for shooting performance ( r = 0.60; 95% CI = 0.35 to 0.77; p < 0.001) in air pistol shooting. Furthermore, in both disciplines, there was a significant positive correlation between shooting performance and measures of aiming accuracy such as COGhit ( r = 0.64; 95% CI = 0.49 to 0.75; p < 0.001), Targetf ( r = 0.75; 95% CI = 0.63 to 0.84; p < 0.001), and Targetr ( r = 0.60; 95% CI = 0.33 to 0.78; p < 0.001). In both disciplines, there was a strong negative correlation between the cleanliness of triggering and shooting performance ( r = −0.63; 95% CI = −0.75 to −0.48; p < 0.001). Time on target measure significantly correlated with shooting performance ( r = 0.52; 95% CI = 0.31 to 0.68; p < 0.001) across both disciplines. The relationship between postural balance and shooting performance in air rifle shooting was negative, indicating that better postural balance is associated with improved shooting ( r = −0.53; 95% CI = −0.69 to −0.33; p < 0.001).

Therefore, the purpose of this study is to assess the pre-activity and post-activity warm-up, stretching, and training practices of National Collegiate Athletic Association (NCAA) Division I and Division III baseball coaches. A total of 686 questionnaires were distributed via email to head collegiate baseball coaches from NCAA Division I and III universities. The questionnaire was designed to gather demographic, professional, and educational information, as well as specific pre-activity and post-activity stretching usage by the coaches. The responses were examined by computing frequency counts and means where applicable. For the statistical analysis, both SPSS version 27.0 and JMP version 13.0 software packages were utilized. Pearson's Chi-squared tests were run where applicable. Results indicated just over 77% of coaches in the present study affirmed the importance of a pre-activity dynamic warmup. When comparing coaching specific certification to pre-activity flexibility practices, it is clear not all coaches comply with suggested pre-activity flexibility recommendations.

The aim of this study was to explore the relationship between ball release speed and selected pace bowling kinematics in 19 elite female pace bowlers. Participants bowled 18 match-intensity deliveries indoors from a full run-up. Peak ball release speed and three-dimensional pace bowling kinematic data were extracted from six deliveries that met specific selection criteria. Linear and non-linear relationships were assessed between ball release speed and selected pace bowling kinematics. Ball release speed was associated linearly with pelvis orientation at back foot contact ( r2 = 0.34, p = 0.048) and non-linearly with thoraco-pelvic lateral flexion at front foot flat ( r2 = 0.69, p < 0.001). Compared to their slower counterparts, faster elite female pace bowlers were more side-on at back foot contact and more upright in the frontal plane at front foot flat. A side-on pelvis orientation at back foot landing is likely to permit greater whole-body angular momentum in the transverse plane of motion. A more upright trunk orientation at front foot flat may be indicative of delayed onset of trunk flexion and representative of optimal segmental sequencing to maximise ball release speed. This knowledge is likely to be useful in the coaching and development of female pace bowlers for the purposes of enhancing ball release speed and therefore match performance.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"48 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140598784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
