Abstract

This research was conducted in March–May 2025 at Nusa Cendana University (UNDANA), Kupang, with the aim of analyzing the biomechanics of upper limb movements in two basic volleyball techniques, namely jump serve and spike. This research began from the importance of understanding biomechanics in improving performance while preventing shoulder and elbow injuries in university volleyball athletes. The research method used a quantitative descriptive approach with a high-speed video-based motion analysis technique (240 fps) analyzed using Kinovea software. The research sample consisted of 20 volleyball athletes from UKM UNDANA (10 male and 10 female) selected by purposive sampling. Parameters included joint angles, arm swing speed, and upper body segment momentum. The results showed that the optimal shoulder angle in the spike (165° ± 4.1) was greater than the jump serve (155° ± 3.6), with a higher arm swing speed in the spike (18.2 m/s ± 1.3) than the serve (14.5 m/s ± 1.1). The arm momentum value for the spike (7.8 kg·m/s ± 0.9) was also greater than the serve (6.2 kg·m/s ± 0.7). An independent t-test showed a significant difference (p < 0.05) in these three parameters. In conclusion, the spike exerted greater shoulder tension, a more explosive swing speed, and greater momentum than the jump serve. These results suggest that coaches should design exercises that synchronize movement and strengthen the shoulder muscles.

Abstract

Purpose: This study examines the integration of sport marketing and sustainability within Indonesia’s growing sports industry, employing a comprehensive mixed-methods approach to identify key challenges, opportunities, and practical strategies for implementing sustainable practices. Materials and Methods: The research employed a mixed-methods design, combining qualitative interviews with 30 industry stakeholders and quantitative surveys of 120 participants. The sample represented diverse sectors, including sports organizations, marketing professionals, athletes, event planners, policymakers, and fans. Result: Findings reveal a significant disconnect between sustainability awareness and practical application; while 65% of respondents demonstrated general awareness of sustainability concepts, only 30% understood their specific relevance to sport marketing. Current initiatives, such as eco-friendly merchandise and green events (25%), were found to be largely ad hoc rather than strategically implemented. Three primary opportunity areas were identified: leveraging Indonesia’s high digital penetration, forming strategic partnerships with sustainability-focused brands, and developing targeted fan engagement campaigns. Notably, 70% of stakeholders recognized the brand reputation benefits of sustainable marketing, though 50% expressed concerns regarding implementation costs and complexity. Conclusion: These findings highlight the critical need for structured educational initiatives and policy support to bridge the awareness-implementation gap. Consequently, the research team developed the "Sustainable Sport Marketing for Indonesia" training program to equip professionals with tools to align marketing strategies with environmental and social goals. The study contributes to academic and practical discourse by demonstrating how sport marketing can drive sustainability in emerging markets, while addressing Indonesia’s unique challenges, such as resource limitations and infrastructure constraints.
