Influence of Badminton Coaches on the Athletes’ Self-Efficacy

This study employed a correlational research method to examine the relationship between coaches’ self-efficacy – specifically in terms of emotion, optimism, work satisfaction and self-confidence -and athletes’ self-efficacy, which includes personality self- efficacy, sports discipline, psychological self-efficacy and professional thought efficacy. A purposive sampling technique was used to specifically select 10 badminton coaches. Meanwhile, stratified sampling was employed to proportionately distribute the 300 athletes from five universities, ensuring representation from different subgroups. This study found no significant correlation between coaches’ self-efficacy and athletes’ self-efficacy as indicated by the p values greatre than the .05 level of significance set in the study. Despite the Spearman rho coefficients ranging from moderate to high, these results were not statistically significant, these findings suggest that while there may be observable trends the relationship between coaches and athletes’ self-efficacy is not conclusively supported by the data.

VIRD: Immersive Match Video Analysis for High-Performance Badminton Coaching.

Badminton is a fast-paced sport that requires a strategic combination of spatial, temporal, and technical tactics. To gain a competitive edge at high-level competitions, badminton professionals frequently analyze match videos to gain insights and develop game strategies. However, the current process for analyzing matches is time-consuming and relies heavily on manual note-taking, due to the lack of automatic data collection and appropriate visualization tools. As a result, there is a gap in effectively analyzing matches and communicating insights among badminton coaches and players. This work proposes an end-to-end immersive match analysis pipeline designed in close collaboration with badminton professionals, including Olympic and national coaches and players. We present VIRD, a VR Bird (i.e., shuttle) immersive analysis tool, that supports interactive badminton game analysis in an immersive environment based on 3D reconstructed game views of the match video. We propose a top-down analytic workflow that allows users to seamlessly move from a high-level match overview to a detailed game view of individual rallies and shots, using situated 3D visualizations and video. We collect 3D spatial and dynamic shot data and player poses with computer vision models and visualize them in VR. Through immersive visualizations, coaches can interactively analyze situated spatial data (player positions, poses, and shot trajectories) with flexible viewpoints while navigating between shots and rallies effectively with embodied interaction. We evaluated the usefulness of VIRD with Olympic and national-level coaches and players in real matches. Results show that immersive analytics supports effective badminton match analysis with reduced context-switching costs and enhances spatial understanding with a high sense of presence.

A novel mathematical model of the badminton smash: simulation and modeling in biomechanics

Applied physics and computer methods in biomechanics have been extensively used in sports science research, including performance and biomechanics analysis. The Brachistochrone problem, which expresses the curve that an object draws quickly under gravitational forces in a vertical position, is one of the most widely used studies in classical mechanics. A similar problem arises when a badminton player intends to hit a smash with the shortest shot time. This paper aims to determine the optimal stroke trajectory for a shuttlecock smash in the shortest time. We simulate the badminton smash movement using a computer program after analyzing the shuttlecock smash analytically and numerically for several conditions. The modeling results show that a cycloid trajectory allows badminton players to smash the shuttlecock in the shortest time. Based on the experimental findings of Tsai, Huang, and Jih’s study and our models, the ratio of clear speed to smash speed is 0.75, which is still in the range of 0.71 to 0.76, and we find that a cycloid trajectory gives the shortest shuttlecock smash time. We concluded that the experimental data from this study’s literature supported our model. The novelty of this study is that we found the first powerful model and simulation of conventional Brachistochrone in the case of a badminton smash of badminton players. For badminton coaches and players, this model formulation is intended as a reference for optimizing shuttlecock shots. Furthermore, another novelty of this research is that it may lead to software that can be used to analyze the muscle strength of badminton players based on their cycloid hand trajectory and shuttlecock speed.

The Effect of Muscles Fatigue on the Knee’s Kinetics and Kinematics Characteristics

Badminton is very popular on college campuses. In badminton, the anterior cruciate ligament of the players has a higher risk of injury. There are many studies investigating the impact of fatigue on the injury of professional athletes, but few studies focused on college students. We hypothesized that the knee joint would experience greater ground reaction forces, valgus moments, and flexion moments of lunge contact in amateur after fatigue than those indicators before fatigue. Ten male badminton amateurs were enrolled in this study. They performed a lunge to hit the shuttlecock at the designated position and then quickly returned to the starting position before and after fatigue. Fatigue was induced by repeated isokinetic flexion/extension of the knee. Lower body kinematics and ground reaction force (GRF) were collected and further used to calculate the lower body joint moments from initial contact to maximum knee flexion. Compared to the pre-fatigue condition, the peak flexion moment (p = 0.012) and peak abduction moment of knee joint (p = 0.01), and maximum horizontal ground reaction force (p = 0.027) increased significantly at the initial contact (p = 0.01). After muscle fatigue, the knee buckling moment and valgus moment increased significantly at initial contact, and the horizontal backward maximum GRF also increased significantly. These changes might increase the injury risk of anterior cruciate ligament (ACL). The fatigue of the muscles around the knee joint did not change the maximum GRF in the vertical direction at the moment of contact. Combined with the results of our study, badminton coaches and teachers should increase the training of lower extremity muscle strength and endurance in our daily class and training, and also should pay special attention to the coordinated development of muscles.

Self-Regulation of Learning in Practice Behavior: Exploratory Observation Study of Indonesian Young Badminton Players

Self-regulated learning is an essential skill in maintaining deliberate practice over years, espe-cially for young athletes. Yet, there has not been many studies done on athlete’s practice behavior. This study measured the behavioral correlation of self-regulation of learning in Indonesian young badminton players during practice. There were two parts of this study: first, a list of behavioral items was generated from coach interviews with six expert badminton coaches. Second, the list was used to observe players practice behavior during three separate practices and the observed players were asked to complete a self-regulation of learning questionnaire. Eleven badminton players aged 12 to 19 from different divisions participated voluntarily in this study. The observation and questionnaire results showed good self-regulation of learning in badminton players. However, the components breakdown did not match with coaches’ concept of self-regulated learning. Players were scored high in effort, yet lacking in metacognitive components which led to less proactive behavior in their learning process. This study highlighted the importance of gaining a complete impression of the players’ self-regulated learning skills during practice to develop and maximise their potential.

Effect of plyometric training on jumping performance and agility in adolescent badminton players

Badminton is one of the most popular racquet sports in the world. The agility and vertical jump are important motor skills to hit a shuttlecock in badminton game. The purpose of this study was to investigate effect of plyometric training on vertical jump and agility in adolescent badminton players. Twenty adolescent (age, 12.5 ± 0.2 years) badminton players were randomly divided into two groups as plyometric group (PG) and control group (CG). All participants were tested to assess agility and vertical jump before (pre-test) and after 6-weeks training period (post-test). Agility performance was assessed with Illinois Agility Test. Vertical jump height was measured with squat jump test using a contact mat. The PG performed plyometric training twice a week, for 6 weeks. There was a significant difference between pre and post-test for squat jump test in both PG (26%) ( p = 0.00) and CG (10%) ( p = 0.016). However, squat jump height significantly increased in PG compared with CG ( p = 0.024). The agility significantly improved in PG (6%) ( p = 0.01), but not CG (2%) ( p = 0.294). Our results show that a six week plyometric training improved agility and vertical jump in adolescent badminton players. Badminton game requires fast changes in direction, vertical jumps, forward lunges around the court. Badminton coaches should take place plyometric exercises in training program.
