This study employs predictive regression analysis to examine the relationship between right hip angle at the javelin throw power position and overall throwing performance among 20 senior national-level Indian athletes aged 20-28. High-speed videography (240 fps) captured via Kinovea software quantified kinematic variables, revealing a significant model (R = .622, R² = .387, F = 11.353, p = .003) where right hip angle explains 38.7% of performance variance. The regression equation, Performance = -0.495 + 0.234 × (Right Hip Angle), confirms optimal extension (90-120°) enhances kinetic chain efficiency, aligning with biomechanical principles of proximal-distal energy transfer. Findings validate hip angle as a trainable biomarker for power position efficacy, offering coaches targeted interventions to elevate throw distances beyond 85m. Limitations include moderate explanatory power, suggesting multivariate extensions incorporating release velocity.
