In addition, while the server is the one who plays the most third shots following a straight return in men's padel (forehand and backhand volleys) and women's (forehand volleys and backhand volleys), the server's partner is the one who plays the most third shots following a lob return in the men's category (trays or smashes and back wall shots) and women's category (trays or smashes and back wall shots). Moreover, the importance of the point and the service position are parameters that affect the shot following the return in men's and women's professional padel.

The objective of this study was to analyze the characteristics of the golden points and the rest of the points in men's and women's professional padel, as well as to identify the differences between both types of points. A sample of 2752 points (1431 men's and 1321 women's) was used from 394 games identified and finished with a golden point, corresponding to 69 matches played in the 2021 season of the WPT circuit. The variables recorded were the type of point (golden points and non-golden points), player serving, tactical service position, number of net exchanges, effectiveness of the partner serving and effectiveness of the last shot through systematic observation. The results indicate that during the golden points in men's padel, the Australian position is usually used more, while in women's padel the Australian position is more common when the player on the right serves and the traditional one when the player on the left serves. In addition, both in men and women, the most common serves are those directed towards the side wall. On the other hand, except for the errors in women's padel during the golden points, the winning shots are made in areas close to the net and the errors in areas at the back of the court.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125503820","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}

Twenty-four players (age 26 ± 4) wore a 10 Hz Global Positioning System device to track locomotor activity during 10 international matches. The locomotor activity of players was allocated to five different phases: (1) established attack, (2) opposition counterattack, (3) established defence, (4) attacking counterattack and (5) offensive pressing, utilising a video analysis-based system. Linear mixed models and post-hoc pairwise comparisons, using estimated marginal means, were utilised to compare the locomotor activity in each phase of play within each position. Significant main effects were found for the phase of play on several locomotor activity metrics ( p ≤ 0.05). With respect to max speed and relative total distance across positions, counterattacks present a unique challenge compared to other phases. Established attack phases evoke lower max speed values than offensive pressing phases for all playing positions as well as compared to opposition counterattacks for defenders, midfielders, and forwards. Positional differences existed during attacking counterattack phases, with defenders producing lower values than both midfielders and forwards for high-speed running, high-speed running efforts, max speed and relative total distance. Depending on the metric, this approach captured 22%–70% of a player's locomotor activity providing valuable insight into the current dynamics of international hockey. This investigation demonstrated positional differences based on the phase of play, which may explain previous research findings regarding positional differences.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122932004","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}

This study sought to examine the effects of mindfulness training on athletes’ competition anxiety and to consider the role of personality traits. Fifty athletes (mean age = 21.87 years, SD = 1.62; 23 females and 27 males) were randomly assigned to a mindfulness group (n = 23), which received 8 weeks of mindfulness training, and a control group (n = 27) receiving no intervention. The athletes’ personality traits, mindfulness level, and competition anxiety were measured according to the study plan before and after mindfulness training, and at an 8-week follow up. Compared with the control group, mindfulness training had a positive effect on the level of mindfulness and self-confidence in the mindfulness group, as well as a greater improvement in cognitive/somatic state anxiety. Improvements remained stable from the end of training to follow up. Additionally, athletes with high activity and high extraversion had more improvement in mindfulness levels and cognitive/somatic state anxiety, respectively, while athletes with low neuroticism demonstrated greater improvement in self-confidence. Mindfulness training helps to reduce athletes’ competition anxieties, and personality traits might affect the improvement effect to a certain extent, which provided a reference for optimizing mindfulness training and developing more personalized psychological training for athletes who display certain personality traits.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133552469","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}

Cross-sectional. 159 participants completed questionnaires on the perceptions of their lead coaches’ TL, perceived basic need satisfaction (autonomy, competence, relatedness) in relation to programme attendance, and feelings of resilience and life-satisfaction in their current life. PROCESS analysis revealed that all differentiated TL behaviours (but high-performance expectations) had a positive indirect effect on outcomes (resilience and life-satisfaction) via competence and a negative indirect effect on outcomes via relatedness. High-performance expectations demonstrated a direct effect on life satisfaction. The results demonstrate how distinct coach transformational behaviours impact differently on the lives of disadvantaged individuals within a sports-based education programme. The differentiated conceptualisation of TL revealed nuanced results, furthering our understanding of how each TL interacts with the three basic psychological needs. Finally, our results demonstrate the significance competence may hold in transferring the effect of different transformational behaviours onto the everyday lives of disadvantaged individuals.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127055924","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}

Finally, we create key performance indicators to check the differences in certain features, i.e., individual player skills and connectivity attributes, between top-tier and the rest of the players, and use dynamic time warping for validation. The outcome of this work is a recommendation tool that helps players to find what needs to be improved in order to achieve their desired goals.

There is still a need for a greater understanding of its role within a complex, dynamic field of inquiry that seemingly relies heavily on the ‘coach as leader’ for a multitude of outcomes (e.g. performance success, athlete development, social outcomes). Given the call for more contextually specific and action orientated research, the aim of this study was to explore the perceptions of coach leadership within the Hong Kong rugby union environment. The study adopted an interpretive paradigm to gain deep insight into coaches’ and players perceptions of leadership in rugby. Data was collected from 16 participants via three separate online focus groups. Qualitative thematic analysis was used to analyse and interpret the data. The findings suggest that for leadership to be effective, coaches must possess a socio-cultural understanding of their context, have a clear vision for their team and have a principle of transformational and value-based leadership to assist with decision making. Additionally, coaches must become role models and demonstrate authentic leadership characteristics to be able to build and maintain relationships with the people in their organisation through effective communication. Sharing leadership appeared to be an effective method adopted by coaches to enhance leadership throughout a rugby organisation. We suggest that the results provide a grounding for coach learning within a unique coaching context.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114394745","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}

Twenty-two male semi-professional players completed a testing session which consisted of unilateral ankle dorsiflexion range of motion, vertical and horizontal unilateral and lateral countermovement jumps and left and right leg 90° (COD90L&R) and 180° (COD180L&R) change of direction tests. No significant differences between limbs were observed for any of the variables ( P > 0.05), though vertical countermovement jump (11.1% ± 9.1%) and dorsiflexion range of motion (10.5% ± 10.3%) imbalances were greater than those during lateral (2.7% ± 2.2%) and horizontal (2.2% ± 1.9%) countermovement jumps, and 90° (3.6% ± 3.1%) and 180° change of direction (2.9% ± 3.6%). Subjects presented 3.4 ± 1.4 real asymmetries (i.e., one greater than the coefficient of variation) across the tests, with all subjects having at least one real asymmetry. Stepwise linear regression models explained a reasonable amount of variance in change of direction180R (70%), COD90L (57%), COD90R (39%), COD180L (23%) using the countermovement jump and dorsiflexion range of motion variables ( P < 0.05). The current findings indicate that semi-professional soccer players have real bilateral asymmetries (particularly in countermovement jump and dorsiflexion range of motion), which practitioners should be cognizant of.
