Training load monitoring is employed to quantify training demands, to determine individual physiological adaptions and to examine the dose–response relationship, ultimately reducing the likelihood of injury and making a meaningful impact on performance. The purpose of this study is to explore the relationship between training load and injury in competitive swimmers, using the session rate of perceived exertion (sRPE) method. Data were collected using a prospective, longitudinal study design across 104 weeks. Data were collected from 34 athletes centralised in two of Swim Ireland’s National Centres. Bayesian mixed effects logistic regression models were used to analyse the relationship between sRPE-TL and medical attention injuries. The average weekly swim volume was 33.5 ± 12.9 km. The weekly total training load (AU) averaged 3838 ± 1616.1. A total of 58 medical attention injury events were recorded. The probability of an association between training load and injury ranged from 70% to 98%; however, evidence for these relationships was deemed weak or highly uncertain. The findings suggest that using a single training load metric in isolation cannot decisively inform when an injury will occur. Instead, coaches should utilise monitoring tools to ensure that the athletes are exposed to an appropriate training load to optimise physiological adaptation. Future research should strive to investigate the relationship between additional risk factors (e.g., wellbeing, lifestyle factors or previous injury history), in combination with training load and injury, in competitive swimmers.

Background/Objectives: Parent–child relationships represent a key factor for the quality of developmental trajectories and impact on children’s social and emotional competence. Therefore, research has advanced the role of parenting by showing the significance of differentiating between distinctive aspects of a parent’s behaviors. This study aims to investigate the role of the feelings experienced in parent–child relationships (e.g., warmth and negative feelings), considering the moderating role of the parental styles toward children’s emotions (e.g., coaching and dismissing). Methods: A total of 136 mothers (M = 38.09 years, SD = 4.51 anni, 48.5% high school degree) with a preschool child (age range 3–5 years) in Central Italy have been involved in a survey during the pandemic period. Results: Multiple regression analyses show that warmth and negative feelings are associated with positive parenting; however, the moderation effect of the dismissing style on both warmth and negative feelings emerged. Conclusions: Despite the characteristics of the data collection period, the results suggest the importance of considering the emotion-related dimensions between parents and their children as they seem to influence parenting behaviors.

In forehand strokes with different grips in tennis, the forearm muscle activities, the distribution and attenuation of the impact loads, and the effects of the muscles on the impact load attenuation exhibited different characteristics. This study aimed to explore these characteristics by analyzing electromyography (EMG) and acceleration data, and comparing the differences between the Eastern and Western grips. Fourteen level II or above tennis players (ten males, aged 22.4 ± 3.6 years; four females, aged 19.8 ± 2.0 years) were recruited and instructed to perform forehand strokes using the Eastern and Western grips, respectively. The EMG of eight forearm muscles and the acceleration data at the ulnar and radial sides of the wrist and elbow were collected. The root mean square (RMS), the peaks of the impact load, the amplitude of impact load attenuation (AC), and the jerk value (Jerk) were calculated. The cross-correlation coefficients and time delays of EMG–EMG, EMG–AC, and EMG–jerk were obtained using the cross-correlation method. The results showed that in the Eastern grip group (group E), the RMS of the flexor carpi ulnaris (FCU) was significantly greater than that in the Western grip group (group W). In group E, the peaks of impact load, AC, and Jerk on the Y axis of the wrist ulnar side were all significantly higher than those in group W. The activity of the extensor digitorum commonis (EDC) had significantly different effects on the amplitude and rate of impact load attenuation at specific locations in different grips, especially at the elbow (p < 0.05). The conclusion indicated that the FCU exhibited higher levels of EMG activity in the Eastern grip. This grip responded to greater impact loads with more substantial and rapid attenuation on the wrist ulnar side. Furthermore, the EDC appeared to contribute more to the amplitude of impact load attenuation in the Western grip and to have a more significant influence on the rate of impact load attenuation in the Eastern grip, especially at the elbow. These results suggest that tennis players and coaches should pay more attention to improving the strength of the EDC and FCU, which can improve sports performance and comfort, as well as prevent sports injuries.

The ATP-PCr system represents the main source of energy during high-intensity attack actions in taekwondo matches. In contrast, the glycolytic system supports the maintenance of these actions when repeated techniques are performed. Given the close relationship between anaerobic energy systems and attack activity in combat, the literature relating to the use of sport-specific test protocols for anaerobic assessment has experienced a remarkable increase. This narrative review aims to illustrate the sport-specific anaerobic tests available in taekwondo by retracing and examining development and validation process for each test. Forty-one articles published between 2014 and 2023 were selected via the MEDLINE and Google Scholar bibliographic databases. These tests are the Taekwondo Anaerobic Test and Adapted Anaerobic Kick Test (i.e., continuous mode testing); the 10 s and multiple Frequency Speed of Kick Tests; the chest and head Taekwondo Anaerobic Intermittent Kick Tests; and the Taekwondo-Specific Aerobic–Anaerobic–Agility test (i.e., intermittent mode testing). Coaches and strength and conditioning professionals can use all the tests described in taekwondo gyms as they feature short and easy-to-implement protocols for monitoring and prescribing specific anaerobic training. The guidelines in this review evaluate each test from several perspectives: basic (e.g., validity, reliability, and sensitivity), methodological (e.g., continuous or intermittent mode testing) and application (e.g., time–motion structure and performance parameters). This comprehensive approach aims to assist stakeholders in selecting the most appropriate test. Full article

Rock climbing has propelled from niche sport to mainstream free-time activity and Olympic sport. Moreover, climbing can be studied as an example of a high-stakes perception-action task. However, understanding what constitutes an expert climber is not simple or straightforward. As a dynamic and high-risk activity, climbing requires a precise interplay between cognition, perception, and precise action execution. While prior research has predominantly focused on the movement aspect of climbing (i.e., skeletal posture and individual limb movements), recent studies have also examined the climber’s visual attention and its links to their performance. To associate the climber’s attention with their actions, however, has traditionally required frame-by-frame manual coding of the recorded eye-tracking videos. To overcome this challenge and automatically contextualize the analysis of eye movements in indoor climbing, we present deep learning-driven (YOLOv5) hold detection that facilitates automatic grasp recognition. To demonstrate the framework, we examined the expert climber’s eye movements and egocentric perspective acquired from eye-tracking glasses (SMI and Tobii Glasses 2). Using the framework, we observed that the expert climber’s grasping duration was positively correlated with total fixation duration (r = 0.807) and fixation count (r = 0.864); however, it was negatively correlated with the fixation rate (r = −0.402) and saccade rate (r = −0.344). The findings indicate the moments of cognitive processing and visual search that occurred during decision making and route prospecting. Our work contributes to research on eye–body performance and coordination in high-stakes contexts, and informs the sport science and expands the applications, e.g., in training optimization, injury prevention, and coaching.

The need to ‘rethink leadership’ is on the radar of many, from global finance and auditing organisations (e.g., Deloitte) and global sports organisations (e.g., the International Olympic Committee) to national and local sports organisations concerned about the decreasing numbers of participants or the lack of women coaches. Yet, is the dominant Western leadership orthodoxy fit for purpose in the 21st century? The purpose of this article is two-fold. First, to advocate for ways of ‘rethinking leadership’ that challenge the current dominant ethnocentric, gender-biased, leader-centric orthodoxy. Second, to introduce an expanded global and diverse leadership paradigm that is underpinned by clearly delineated dimensions of diversity and cultural competence, which recognises the importance of the organisational and cultural contexts. The literature discussed in this article draws from leadership studies generally and sports leadership and sports coaching more specifically. Key to this article is the discussion of the implications of adopting a diverse leadership paradigm for policy, practice, development, and research of leadership. This advocacy article does not end with a definitive conclusion but rather with an invitation to participate in a journey to realise the potential of diverse leadership. Full article

The prevalence of sexual harassment and abuse in school sport, specifically by coaches against their athletes, remains a concerning and pervasive issue. In an attempt to better understand and prevent specific coach-behaviours associated with such sexual misconduct, researchers have developed the Sexual Violence Questionnaire in Sport. While the reliability of this measurement tool has been tested in Anglo-Saxon cultural contexts, it is not known whether the questionnaire is applicable to other cultural contexts. This study aimed to analyse the internal consistency and reliability of the questionnaire on sexual harassment in sport, originally designed and developed in English. A sample of 146 (52 female, 94 male) undergraduate students from a university in the Basque Country participated in this cross-sectional study. The questionnaire was administered twice over a two-week period to assess test–retest reliability. The internal consistency of the Sexual Violence Questionnaire in Sport was high, with Cronbach’s alpha values of 0.891 for perceptions and 0.813 for experiences across all participants. Gender-specific analysis showed similar reliability, with females having slightly lower alpha values for perceptions. Although significant differences were observed between the test and the retest on eight perception items and one experience item, Cohen’s kappa analysis indicated agreement on all items; however, some of them were low (e.g., 0.13). In conclusion, the study highlights the questionnaire’s overall reliability and suggests its effectiveness as a tool for measuring sexual violence in sport within the Spanish context. Nonetheless, the findings of this study underscore the need for further research to enhance the instrument’s stability and to better understand gender differences in perceptions and experiences of sexual violence in sport contexts.

This real-life data collection aimed to expand an existing reference database regarding an extensively evaluated ice hockey-specific complex test (IHCT). One hundred and thirty-eight third-league professional ice hockey field players (mean ± SD; age: 26.4 ± 5.24 years; forwards: n = 94, defenders: n = 44) were investigated. IHCT data were collected over eight seasons from three third-league teams. The IHCT included parameters for the load (e.g., 10 m and 30 m sprint times, transition and weave agility times with and without a puck, slap and wrist shots on goal) and stress (e.g., lactate, heart rate). The only relevant (p < 0.002, η_p² ≥ 0.10) difference between forwards and defenders for performance was found for 30 m backward sprint without a puck (p < 0.001, η_p² = 0.10, d = 0.74). As expected, in this regard, defenders performed better than forwards. Significant differences were also found in 10 m backward sprint without a puck (p = 0.005), weave agility with a puck (p = 0.014), heart rate recovery minute 10 (p = 0.057), and goals after the test (p = 0.041). This study provides expanded position-specific third-league reference data for the IHCT. On this basis, coaches are able to evaluate players’ performance (forwards vs. defenders) and the effect of the training periods. Further research is necessary to extend this database to first- and second-league players in order to enhance the scope of the IHCT. Full article

Veterinary coaching was tested to assess its efficacy in promoting adherence to biosecurity procedures. Poultry farmers (n = 13) in Belgium were profiled using ADKAR^®, coached and audited prior to and 6 months after coaching. The ADKAR^® (Awareness, Desire, Knowledge, Ability, and Reinforcement) profiling technique identified 5/13 participating farmers with relatively low scores (≤3) for one or more elements that block change (biosecurity compliance in this case). Education was the only demographic variable that influenced knowledge scores. Through the Biocheck.Ugent^TM methodology, farm biosecurity was assessed and benchmarked to allow for tailored guidance. The farmer, farm veterinarian, and coach defined a farm-specific action plan that covered infrastructure, site access, staff/visitors, purchase policies, transport and depopulation, feed and water supplies, flock management, cleaning and disinfection between flocks, and measures between houses. From a total of 49 proposed actions, 36 were adopted. Purchasing policy had the highest (100%) and cleaning and disinfection had the lowest compliance (38%). Time, cost, and feasibility (e.g., inadequate farm layout) were the main reasons cited for not implementing action points. Overall, biosecurity improved significantly (p = 0.002) from 67.1 ± 5.7% to 70.3 ± 5.7% (mean ± Std. dev). The study, hence, presents convincing proof of how coaching can lead to new solutions not previously considered. Full article

Extended reality (XR) systems are about to be integrated into our daily lives and will provide support in a variety of fields such as education and coaching. Enhancing user experience demands agents that are capable of displaying realistic affective and social behaviors within these systems, and, as a prerequisite, with the capability of understanding their interaction partner and responding appropriately. Based on our literature review of recent works published in the field of co-speech gesture generation, researchers have developed complex models capable of generating gestures characterized by a high level of human-likeness and speaker appropriateness. Nevertheless, this is only true in settings where the agent has an active status (i.e., the agent acts as the speaker), or it is delivering a monologue in a non-interactive setting. However, as illustrated in multiple works and competitions like the GENEA Challenge, these models remain inadequate in generating interlocutor-aware gestures. We consider interlocutor-aware gesture generation the process of displaying gestures that take into account the conversation partner’s behavior. Moreover, in settings where the agent is the listener, generated gestures lack the level of naturalness that we expect from a face-to-face conversation. To overcome these issues, we have designed a pipeline, called TAG2G, composed of a diffusion model, which was demonstrated to be a stable and powerful tool in gesture generation, and a vector-quantized variational auto-encoder (VQVAE), widely employed to produce meaningful gesture embeddings. Refocusing from monadic to dyadic multimodal input settings (i.e., taking into account text, audio, and previous gestures of both participants of a conversation) allows us to explore and infer the complex interaction mechanisms that lie in a balanced two-sided conversation. As per our results, a multi-agent conversational input setup improves the generated gestures’ appropriateness with respect to the conversational counterparts. Conversely, when the agent is speaking, a monadic approach performs better in terms of the generated gestures’ appropriateness in relation to the speech. Full article

Young individuals with autism spectrum disorder (ASD) seem to attend higher education more frequently. Yet, the academic performance of students with ASD and the graduation rate appear to be poorer than those of typical development students. Moreover, college students with ASD face several challenges in their everyday and social lives. Students with ASD seem not to receive the appropriate social and educational support in higher education. This article reports the results of a systematic literature review of research programs and services designed to meet the needs of students with ASD enrolled in higher education. Several interventions are available and appear to be effective in supporting students with ASD in higher education (e.g., social planning intervention, focus groups, coaching paired with behavioral skills training, video feedback, visual framework, peer mentoring, and virtual reality). In addition, this article shows that colleges and universities face the challenge of preparing for these students and the need to provide psychological support for them. Moreover, studies of experiences and opinions of college students with ASD from their perspectives are included. Full article

Recently, the integration of coaching methodologies within educational environments has garnered significant attention due to their potential to enhance student learning outcomes and overall academic performance. While the literature extensively examines the effectiveness of coaching in a plethora of scenarios (e.g., sports, business, and entrepreneurship), there remains a notable research gap regarding its application within undergraduate educational environments, where coachees have unique characteristics in terms of background, age/maturity, resources availability, and population size. This literature review aims to address this gap by synthesizing existing research on the implementation of coaching strategies in educational settings and how they can cope with a large number of students. Through a comprehensive analysis, this study elucidates the current state of knowledge, identifies prevailing methodologies, and evaluates the outcomes associated with employing coaching techniques in group contexts. Moreover, this work explores the potential benefits and challenges of utilizing coaching strategies in group sessions, offering insights into their scalability and applicability within diverse educational settings. The findings of this review underscore the importance of further research in this domain to advance our understanding of how coaching methodologies can be effectively adapted to facilitate collaborative learning experiences and promote student success on a broader scale. Ultimately, this study advocates for the integration of group coaching approaches as a promising avenue for enhancing the efficiency and accessibility of traditional tutoring and mentoring practices in education.

Most studies on sprint performance have focused on kinematics and kinetics of the musculoskeletal system for adults, with little research on the central sensorimotor transmission and processes, especially for adolescent sprinters. This study aimed to determine whether differences in the integrity of the central auditory system and audiomotor transmissions between the elite and sub-elite adolescent sprinters may affect their performance in the 100 m time. Twenty-nine adolescent junior high school students, including elite national-class and sub-elite regional-class athletes, were assessed. Visual and auditory evoked potentials (VEP and AEP) as well as electroencephalography (EEG) and electromyography (EMG) were recorded and analyzed during a sprint start. The electrophysiological results clearly reveal differences in central auditory transmission between elite and sub-elite groups, and between sexes. There were significant differences between elite and sub-elite groups, and during a sprint start, the EEG activities for elite female and male athletes showed significant time-dependent differences in peak amplitudes following the three auditory cues (ready, set, and gunshot). These findings can provide coaches with a more comprehensive consideration for sports-specific selection based on the athletes’ individual conditions, e.g., sensorimotor neuroplastic training for providing precise and efficient training methods to improve young sprinters’ performance.

Background: Excessive or improper use of dietary supplements (DSs) by athletes may cause adverse effects, such as impaired performance or failing a doping test, making it important for athletes to mitigate risk and make well-informed choices when using supplements. Methods: This study used focus group interviews to examine the attitudes, motivations, and practices related to DSs among male elite ice hockey players. Results: The players used a wide range of products, ranging from vitamins to multi-ingredient pre-workout supplements. Consuming DSs was considered as a practical and convenient way to ingest sufficient calories to gain or maintain the body weight and muscle mass needed to meet the physical requirements of the sport. The athletes demonstrated a lenient and ignorant attitude when acquiring and using supplements, with a non-critical trust in the guidance provided to them by the coach or physician. Having completed basic anti-doping education in the form of an e-learning program did not appear to result in taking a more careful approach to using DSs. Conclusions: Through their DS practices, elite ice hockey players may put themselves at risk for anti-doping rule violations. A comprehensive approach is needed when aiming to prevent unintentional doping in this athlete cohort. Full article

Teaching practices are moving from decontextualised to more representative curricula. Although this is argued to be a positive step, low motor competence is a continual issue in primary-aged school children. One methodological approach to investigate ways to improve motor competence, eye tracking, is moving to more representative tasks. So far, eye-tracking research using static activities has demonstrated a positive association between motor competence and earlier fixation and longer duration. However, this research has been constrained to laboratory settings and tasks, or discrete activities (e.g., throw and catch). This study seeks to understand how to conduct more representative eye-tracking research in primary school-aged children. To this end, thirteen 10–11-year-old children were fitted with an eye-tracker during a typical football coaching session. Children were asked acceptability-based questions, and eye-gaze data were captured to illustrate what children attended to under a representative dynamic football-based activity. Based on the voices of children and captured eye-gaze data, six practical implications for research in this population are proposed: (1) conduct eye-tracking research indoors (where possible); (2) ensure long hair or fringes are secured so as not to obscure line of sight; (3) run the same activity to increase comparability across children wearing the eye-tracker; (4) use a properly fitted backpack (if a backpack is to be used); (5) assure children about the capability and hardiness of the eye-tracker, as they do not need to change the way they move; (6) explain there may be some discomfort with the nose clip, head strap, and battery weight and ensure that children wish to continue.
