A Correlational Study of Static and Dynamic Strength in Relation to Vertical Jump Performance Among Basketball Players

Introduction: The performance of Indian athletes in national and international competitions has been consistently below expectations, despite longstanding efforts to enhance their capabilities. Physical fitness plays a pivotal role in athletic performance. Defined as the ability to perform daily tasks with vigour and minimal fatigue, physical fitness is essential for success in sports. Recognizing the need for sport-specific fitness assessment, this study was conducted at the Department of Exercise and Sports Physiology, Dr. Vaishampayan Memorial Govt. Medical College, Solapur. Aims and Objectives: i) To assess height, weight, muscular strength, and vertical jump in basketball players. ii) To examine the correlation between muscular strength and vertical jump power. Material and Methods: Thirty (30) male university-level basketball players aged 18–19 years (mean age 18.6 years) participated in this study. Anthropometric measurements (height and weight) were recorded. Dynamic strength was assessed via bench press and bench squat, while static strength was evaluated using a leg and back dynamometer. Vertical jump height was measured to the nearest centimetre. Results: Significant correlations were observed between muscular strength and vertical jump performance. Bench press showed a strong positive correlation with vertical jump power (p < 0.0001), while bench squat exhibited a weaker yet significant correlation (p < 0.01). Static leg strength showed a statistically significant negative correlation (r = –0.49) with vertical jump power. Discussion and Conclusions: The study highlights that both dynamic and static strength are influential in vertical jump performance. Findings emphasize the importance of targeting specific muscle groups to enhance explosive power in basketball players.
