To generate swing, bowlers must use a technique that creates an angled and upright ball seam when it is released from the hand and projected towards the batter. The ability to create both inswing and outswing can provide bowlers with an advantage over opposition batters and requires a high level of skill, but little is known about the bowling actions to achieve this. This exploratory investigation aimed to compare the ball grip angle, bowling arm joint angles during the delivery stride and bowling arm segment orientations at the point of ball release of conventional new ball inswing and outswing deliveries. A three-dimensional motion analysis system captured a group of 10 pathway and elite Australian fast bowlers delivering inswing and outswing. Statistical differences were observed in ball grip (<i>p</i> = 0.041), elbow pronation–supination (<i>p</i> = 0.050), shoulder adduction–abduction (<i>p</i> = 0.002), forearm lateral (<i>p</i> = 0.009) and hand lateral (<i>p</i> = 0.002) angles. These differences in bowling mechanics may assist bowlers in achieving the desired ball release positions and seam angles required to swing the ball in both directions. The findings of this study provide initial insight into the biomechanics of swing bowling, allowing for hypotheses that are generated from the data to be tested in future research and offering athletes and coaches strategies that can be employed to enhance performance.</p>","PeriodicalId":93999,"journal":{"name":"European journal of sport science","volume":"25 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ejsc.12321","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For simple tasks, feedback had little impact on long-term retention, whereas for complex tasks, differences were significant.

Therefore, the aim of this study was to investigate: (a) the prevalence of injury in youth grassroot football players and (b) the relationships between prevalence of injury and potential risk factors; namely, sex, age group, social support, coach and peer autonomy support, and training load. Adolescents (<i>n</i> = 568; <i>M</i>_age = 15.7 years; and SD = 1.4) playing for U14–U19 teams in Agder County in Norway provided information pertaining to their participation in grassroot football.

Moreover, the results revealed that a higher injury prevalence was associated with a combination of lower levels of peer autonomy support, higher weekly accumulated total football activity, and being female. For substantial injuries, the combination of higher amounts of match time or being a player who perceived lower levels of coach autonomy support in the group accumulating least match time was associated with a higher injury prevalence.

However, method comparisons are underexplored. This study compared MAS estimation via a 6-min distance trial (6minDT), 1800-m time trial (1800mTT) and 30-15 intermittent fitness test (30-15IFT) and qualitative preferences in academy soccer players. Twenty-six male players (age: 17.2 ± 0.6 years; stature: 178.4 ± 5.1 cm; body mass: 71.8 ± 7.7 kg) completed a 30-15IFT, 6minDT and 1800mTT in a counterbalanced order. Total distance was measured via 10 Hz global positioning system units, with MAS defined as 87% of 30-15IFT finishing speed (<i>v</i>IFT) and distance divided by time to completion for the 6minDT and 1800mTT. Pearson's correlations calculated associations between MAS estimates, and a robust repeated measures ANOVA estimated marginal mean differences between tests. A very large association was observed between performance in the 1800mTT and 6minDT (<i>r</i> = 0.72; 95% confidence interval, 0.46 to 0.86).

MAS estimated from the 6minDT was lower than the 1800mTT (−0.13, −0.21 to −0.05 m·s⁻¹, <i>p</i> = 0.0002). In conclusion, although associations between 6minDT-, 1800mTT- and 30-15IFT-derived MAS exist, all tests provide distinct estimations of MAS.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Trial Registration</h3>\u0000 \u0000 <p>This study was pre-registered on 11/03/2024.
