Abstract

Background: Ball backspin is created during a basketball's final release. The complex nature of the hand-ball interaction at the moment of release can result in spin axis (SA) misalignment, which decreases shooting accuracy.Aims: This study is the first to analyze distinct backspin modes, such as hand orientation, twist, and push location, and how each mode contributes to overall SA misalignment.Methods: Three-dimensional ball backspin, hand orientation, hand position, and ball twist before release were measured for 20 male basketball athletes. The multiple linear regression test analyzed SA misalignment about the vertical axis (ey) and side SA misalignment (ez).Results: The multiple linear regression for SA misalignment about the vertical axis (ey) found that the orientation of the fingers and twist modes were equally important while the push location was insignificant (f2 = 1.9, R2 = 0.63, F = 17.0, p less than 0.001). For side SA misalignment (ez), all three modes contributed to ez misalignment (f2 = 3.3, R2 = 0.77, F = 18.1, p less than 0.001), with both the orientation of the palm and twist modes contributing equally and the vertical push location having a smaller contribution.Conclusion: This study demonstrates that five different backspin modes—two for ey and three for ez—each have distinct effects and combine to produce the final SA alignment after the ball is released. Knowing how each mode contributes to the final SA misalignment will allow coaches to identify necessary changes in individual players' shooting techniques to improve their release and increase accuracy.

Abstract

Background The physical demands of cricket, particularly in youth players, encompass critical components of strength, endurance, and agility, which are essential for optimal performance and maintaining competitive success. Strength, endurance, and agility are vital in enhancing youth cricketers' overall physical fitness and performance levels, directly influencing their ability to sustain high-intensity efforts, execute precise movements, and recover effectively during matches and training sessions. Aims: This research aimed to evaluate the field-based performance levels of young cricketers in Belagavi through innovative assessments: the wall squat, 2km time trial, and Run-a-three tests, highlighting their importance in enhancing player fitness and performance.Methods: A cohort of 100 young cricketers (aged 18-24) with a minimum of 2 years experience underwent comprehensive assessments using the wall squat, 2km time trial, and Run-a-three tests across various cricket grounds in Belagavi. Statistical analyses provided insights into their fitness levels across different player categories (batsmen, bowlers, all-rounders, and wicketkeepers).Results: Significant variations in fitness levels were observed among player categories, with wall squat endurance being the most notable area for improvement, as the mean performance was 51.54 ± 20.79 seconds. The average 2km trial was completed in 10.03 ± 1.42 minutes, while the Run-a-three drill averaged 11.86 ± 1.33 seconds. These findings highlight the critical need for targeted fitness interventions to enhance lower body endurance across all roles.Conclusion: This study underscores the imperative for tailored fitness regimens to address deficiencies in strength, endurance, and agility among young cricketers in Belagavi. These targeted interventions can enhance their competitive readiness and support long-term athletic development. Future research should explore the specific impact of these fitness interventions on performance metrics and injury prevention, providing further insights into optimizing youth cricket training programs.

Abstract

Background: Numerous studies have explored the effect of coach-athlete relationships on athletes' burnout, yet there has been a notable gap in the mediating role of coach leadership.Aim: This study sought to investigate how perceived coach leadership affects athlete burnout and its implications for the quality of coach-athlete relationships.Methods: A total of 248 athletes from individual, dual, and team sports participated, comprising 142 (57.26 percent) males and 106 (42.74 percent) females, aged between 18 and 35 years (M= 20.24, SD = 2.02), all based in Iligan City. The study examined the variables and their connections by employing a descriptive-correlational methodology. The researchers utilize a snowball sampling technique to expand the sample through referrals.Results: The findings revealed that coach leadership does not directly mediate the relationship between the coach-athlete dynamic and athlete burnout. However, the quality of the coach-athlete relationship significantly impacts burnout. Key relationship factors, such as emotional closeness, complementarity, and commitment, play crucial roles. Athletes who reported stronger relational bonds with their coaches, characterized by trust, open communication, and shared goals, experienced lower levels of burnout. Conversely, weaker relationships, marked by conflict or lack of emotional connection, were linked to higher burnout levels. Conclusion: While coach leadership does not serve as a mediator, it plays a vital role in fostering a supportive coach-athlete relationship, significantly reducing burnout. This study emphasizes the significance of fostering robust relationships between coaches and athletes to reduce athlete burnout. Sports coaches should prioritize relationship-building over merely employing leadership skills since this can significantly enhance an athlete's emotional resilience and mental well-being. Coaches must emphasize cultivating closeness with athletes by promoting open communication, trust, and empathy.

Abstract

Background: Throwing events involve the full use of the kinetic chain. Therefore, monitoring training loads is crucial to optimizing athlete adaptation while minimizing the risk of fatigue and long-term injury.Aims: This study aimed to determine external load using work calculations and compare them to current session internal workload metrics such as heart rate and rate of perceived exertion. Furthermore, it aimed to monitor workload over a nine-week period.Methods: Internal training load was evaluated using modes of heart rate monitoring and rate of perceived exertion. External training load was calculated as the product of throw distances and implement weight. Acute to chronic workload ratio was calculated by dividing the acute workload by the chronic workloadResults: Twenty-five throwing athletes (age: 19 (3); height: 1.82 (0) meter; mass: 93 (19) kilogram) completed 11 (7) throws in a single field session during which throwing work was calculated (Throw distance: 40.87 (17.54) meter; session-rating of perceived exertion: 198 (269) arbitrary units; Total work: 8719.37 (13960.6) Joule; Average work: 726.61 (1877.92) Joule). Correlations (p less than 0.05) were found between session rating of perceived exertion and average work (r=0.433), session duration and total (r=0.433), and average workload (r=0.523). Negative correlations existed between average heart rate and total work (r=-0.435), average work (r=-0.442), and duration. (r=-0.483). Workloads and acute to chronic workload ratio differed over the 9 weeks (p=0.025).Conclusion: Relationships were reported between calculated average work, s-RPE, session duration, and average heart rate, indicating that monitoring the duration of training sessions will be of value while changing the implement weight in the sessions.

Abstract

Background: There is an urgent need to explore innovative training methods that can improve the physical condition and back-row attack performance of junior volleyball players. Despite its great potential, Virtual Reality (VR) is still underutilized in youth sports training.Aims: This study aims to test the effectiveness of VR-based training in improving physical conditioning and back-row attack quality.Method: A quasi-experimental design was employed with 24 junior volleyball athletes aged 14 to 16. The participants underwent VR-based training three times a week for six weeks, with each 45-minute session consisting of a 15-minute warm-up, a 30-minute training session, and a 5-minute cool-down. Measurement tools included vertical jump tests, 20-meter sprints, Illinois agility tests, and structured observations to evaluate physical performance and back-row attack effectiveness. Data were analyzed using paired t-tests and multiple linear regression.Result: The results showed significant improvements in vertical jump height (d = −8.18), sprint time (d = 2.42), agility score (d = 3.32), and back row attack (d = −3.32) at p 0.001. Structured observations revealed improvements in the accuracy, timing, and coordination of back-row attacks. Regression analysis revealed that a better physical condition, particularly in terms of jumping and agility, significantly contributed to improved back-row attack performance (R² = 0.876, p 0.001).Conclusion: These findings suggest that VR-based training can effectively enhance physical condition and technical performance in back-row attacks, likely due to the immersive simulation environment supporting enhanced motor learning and situational awareness.

Abstract

Background: Doping remains a persistent issue in martial arts, exacerbated by the easy access to over-the-counter medications containing banned substances. Despite existing regulations, athletes often lack comprehensive knowledge of anti-doping measures, leading to unintentional violations.Aims: This study aims to evaluate the effectiveness of a doping management program in improving knowledge and awareness of doping among martial arts athletes.Methods: A convergent parallel mixed-methods design was employed. Twenty-one national-level martial arts athletes were selected using purposive sampling. Data were collected through structured interviews and standardized questionnaires. The doping management intervention included a web-based doping screening tool, an anti-doping educational module, and a 24-hour online consultation clinic implemented during the 2024 National Sports Week (PON) training period.Results: Results showed a significant increase in athletes' knowledge of doping, with the mean score rising from 54% to 76% (p = 0.002), especially in terms of understanding Therapeutic Use Exemptions (TUEs). However, the study also found low utilization of online doping clinics, confusion regarding TUE procedures, and continued reliance on coaches for drug use. Document analysis and institutional mapping showed that coordination between stakeholders was fragmented, and socialization of anti-doping services was not optimal.Conclusion: The findings underscore that coaches play a pivotal role in doping management, serving as primary sources of information and guidance for athletes. Strengthening the involvement of coaches in anti-doping education is essential to maintaining a doping-free environment and ensuring the success of doping prevention strategies in martial arts.

Abstract

Background: Training methodologies in badminton often focus on technique and endurance, yet the integration of scientific principles, such as torque, remains underutilized. As a critical factor influencing shot power, speed, and accuracy, a deeper understanding of torque can optimize training effectiveness and systematically enhance athlete performance.Aims: This research aims to analyze prospective badminton coaches’ understanding and application of physics concepts, particularly torque, in training methodologies.Methods: This research employed the qualitative descriptive method involving 24 prospective badminton coaches (17 males and 7 females, aged 18-22) in Bandung, Indonesia. A survey was conducted to assess their understanding of physics and its application in training. Data collected through the questionnaire was analyzed using NVivo software, which facilitated thematic analysis and coding of qualitative responses.Results: The findings indicate that, while most of the respondents are familiar with physics terms, only a few recognize torque as a relevant concept in the badminton context. A deeper understanding of torque can help coaches optimize playing techniques by improving racket rotation efficiency, thereby enhancing hitting power with minimal energy expenditure.Conclusion: This research demonstrates that integrating physics concepts, particularly torque on the racket, into badminton training provides a valuable perspective for improving training quality. The findings suggest that badminton coach training programs should integrate physics concepts to enhance training effectiveness and efficiency while systematically improving athlete performance based on scientific evidence.

Abstract

Background: A racket's performance in controlling trajectory and manipulating the speed of the ball is greatly influenced by its structural characteristics and materials. The material of the table tennis racket can affect its performance, reducing the speed and control of the ball.Aims: The main objective of this research is to analyze the biomechanical performance of the Garuda Unesa Speed (GUS) table tennis racket made from Makassar ebony veneer as the main material and to compare its attributes, particularly speed and control, with those of high-end commercial rackets.Methods: This study applies a comparative design by comparing two types of rackets in table tennis. Two-dimensional kinematics analysis was also conducted using Kinovea software.Result: Based on the t-test results with a non-parametric path, all variables showed a significant difference with a p-value of 0.01 (Sig 0.05). However, one variable did not show a significant difference, namely the velocity variable, with a p-value of 0.05 (Sig 0.05). If examined from the average value, the speed variable has a slight difference (a difference of 0.5). The average speed data shows that the Makassar ebony wood veneer racket has better speed.Conclusion: Based on the results of biomechanical analysis, the reflection of the Makassar ebony wood veneer racket makes a good contribution to the speed and control of the table tennis racket. This finding has practical implications for designing an effective table tennis athlete smash and block game by utilizing the speed and control of a table tennis racket using Makassar ebony wood veneer.

Abstract

Background: Energy drinks are commonly consumed by athletes due to their caffeine and stimulant content, which is believed to enhance performance. Previous research suggests benefits for anaerobic power and reaction time, but their effects on cardiovascular endurance and physiological responses remain inconclusive.Aims: This study aimed to examine the acute effects of energy drink consumption on cardiovascular endurance, blood pressure, and heart rate among collegiate athletes in the Philippines.Methods: Using a one-group pretest-washout-posttest design, 21 collegiate athletes (12 males, 9 females) participated. Cardiovascular endurance was assessed using the beep test. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured using a digital sphygmomanometer (Omron 10 Series BP7450), while heart rate (HR) and heart rate recovery (HRR) were monitored digitally. Participants underwent a pretest, consumed 330 ml of energy drink, completed a washout period, and then performed a post-test. The Shapiro-Wilk test was used to assess normality, and paired sample t-tests determined pre–and post-test differences.Result: Energy drink intake did not significantly improve cardiovascular endurance (p .05). However, significant increases in DBP (p = .040) and HR (p = .029) were observed in males. At the same time, females showed a significant rise in SBP (p = .032). HRR significantly improved in females (p = .031), indicating a possible short-term recovery benefit. Combined results showed a significant increase in DBP (p = .021), while HRR approached significance (p = .055).Conclusion: Although no enhancement in cardiovascular endurance was observed, energy drinks acutely influenced cardiovascular markers, raising blood pressure and heart rate in males and enhancing HRR in females. The absence of a control group and uncontrolled variables, such as caffeine metabolism, hydration, and socioeconomic factors, limit causal conclusions. These findings suggest the need for sex-specific guidance when using energy drinks. Future randomized trials with larger samples are recommended.
