Methods： Two hundred and fifteen members of competitive sports clubs responded to scales measuring coach characteristics of justice, benevolence, integrity, and competence; athlete＇s trust in the coach; commitment to coach; willingness to cooperate; and perceived performance. Results： Confirmatory factor analysis of data supported the measurement model. Perceptions of a coach＇s justice （β = 0.19, p 〈 0.05）, benevolence （β = 0.32, p 〈 0.05）, integrity （β= 0.14, p 〈 0.05）, and competence （β = 0.29, p 〈 0.05） each had a significant effect on athletes＇ trust, and they cumulatively accounted for 61% of the variance in trust. The structural equation modeling showed that trust had direct effects on commitment to coach （β = 0.77, p 〈 0.01）, willingness to cooperate （β= 0.79, p 〈 0.01 ）, and perceived performance （β = 0.51, p 〈 0.01）,. The hypothesized mediating effects of commitment to coach and willingness to cooperate were not supported. The model explained 26% of the variance in perceived performance. Conclusion： As trust in coach influences commitment to coach, willingness to cooperate, and perceived performance, coaches need to take effort to bolster their athletes＇ trust by being just and benevolent, and enhancing their integrity and competence.展开更多

The bowing distortions of the welded plates were measured using a simple device called profile tracer. An experimental regression equation was developed to predict the bowing distortion and with this equation, it is easy to select optimized process parameters to achieve minimum bowing distortion. It is revealed that the FCAW process parameters have significant influence on bead profile and the bowing distortion.展开更多

Its capabilities, ranging from machine learning to real-time feedback systems, enable coaches to process complex data and enhance decision-making. This study investigates the integration of AI into sports coaching, emphasizing its potential to revolutionize training efficiency, optimize athlete performance, and reduce injury risks. However, AI implementation still faces challenges such as technical complexity, budgetary constraints, data privacy and ethical considerations, and psychological resistance. Research Objective: The purpose of this study is to explore the efficient use of AI in sport coaching, to propose strategies to address the challenges encountered in implementation, and to provide implementation guidelines for sport organizations. Research Methodology: This paper provides an in-depth analysis of the application of AI in data analysis and training adjustments, injury prediction, and personalized training regimens through literature review and case studies, and proposes effective implementation strategies in combination with actual cases. Findings: The study found that AI technology has significant advantages in enhancing training science and effectiveness, such as real-time data analysis tools and machine learning models that can improve training personalization and science, and AI-driven biomechanical analysis and injury prediction systems that can help to reduce the risk of injuries and improve safety for athletes. However, technical complexity, financial pressures, and data privacy concerns limit their use in small and medium-sized organizations. Research Conclusion: Successful implementation of AI technology in sports coaching requires a multi-layered strategy that includes ongoing training, strategic partnerships, and phased introduction. Future research should focus on combining with emerging technologies such as virtual reality and augmented reality, as well as ensuring the sustainability of the technology in long-term application, realizing deep integration with coaching expertise, and building a comprehensive and efficient training system.展开更多

Data were captured on(1) informational needs and desires,(2) preferred methods of delivery, and(3) concussion practices and procedures. Questionnaires were completed electronically from June 3 rd–September 29 th, 2015.Results: Coaches indicated that they were most interested in receiving information about the(1) signs and symptoms of concussion,(2) assessment of concussion, and(3) return-to-play guidelines. Over two-thirds of participants indicated that in-person training would be the most effective mode of delivery of concussion education for this population. Additionally, only 10% coaches reported that before the start of the season they talked to their athletes about concussion management and safety, and this was more common among coaches who reported being formally educated about concussion.Conclusion: Our findings reveal a disconnect between the concussion education needs and the education that is currently provided to GAA coaches, in terms of content and delivery modality. Our results suggest a need for a multifaceted approach to concussion education, tailored to the needs and learning preferences of the target population.展开更多
