n the literature, the relationships between body composition, sprint speed, and explosive power have been extensively examined across various sports disciplines. However, studies specifically ad-dressing these interrelationships within the context of handball remain limited. Given the unique physical demands of handball, sport-specific assessments are essential. Accordingly, the aim of the present study is to investigate the relationships among peak power, 30-meter sprint performance, and body mass index (BMI) in male handball players.This cross-sectional study included a total of 42 male handball athletes. Anthropometric measurements, including height (cm) and body weight (kg), were collected from participants, andBMI (kg/m²) was calculated accordingly. Motor perfor-mance assessments were conducted under standardized conditions using a vertical jump test (to measure peak power) and a 30-meter sprint test (to assess sprint performance). The findings re-vealed that 30-meter sprint performance was not significantly associated with either peak power or BMI. However, a statistically significant and strongly positive relationship was found between peak power and BMI. These findings suggest that peak power is closely related to body composition, whereas sprint performance is influenced by more complex and multifactorial determinants. There-fore, a comprehensive assessment of physical fitness in handball players, along with the develop-ment of individualized training programs and detailed analysis ofbody composition, is critical for performance enhancement. Future research is recommendedto explore these relationships across larger sample sizes and with more comprehensive test batteries.
