Background: Vertical jump performance is a key indicator of athletic ability, however, evidence on its relationship with body weight remains inconsistent. Since jump performance depends on strength, body composition, and neuromuscular factors, it was hypothesized that vertical jump performance would not be adversely affected by body weight in athletes with average BMI. This study examined the relationship between body weight, BMI, and vertical jump performance in young basketball players. Methods: A cross-sectional study was conducted with 29 male basketball players (mean body weight 77.27 ± 9.20 kg; BMI 22.97 ± 0.97) who volunteered to participate. Standardized biometric assessments and vertical jump tests were administered. Pearson correlation analysis was performed to assess associations between body weight, BMI, and jump performance. Results: Moderate positive correlations were identified between body weight and vertical jump performance (r = 0.392, p < 0.05) and between BMI and vertical jump performance (r = 0.394, p < 0.05). However, low explanatory power (R²) indicates limited predictive value of body weight and BMI. A strong positive correlation between body weight and BMI (r = 0.550, p < 0.01) was also observed. Conclusion: Body weight and BMI showed limited predictive ability for vertical jump performance in young basketball players. Factors such as muscular strength, fat percentage, and neuromuscular efficiency may play a more significant role in jump ability. These findings highlight the necessity of comprehensive performance assessment and individualized training strategies in athletic populations.
