Survey of Leg Muscle Explosive Power among Unsika Sports Science Students and Female Athletes (Class of 2025)
Abstract
This study aims to describe the lower-limb explosive power profile of student-athletes from the Sports Science Study Program at Singaperbangsa Karawang University (Unsika) Class of 2025 using the Vertical Jump Test. A quantitative descriptive survey was conducted involving 25 participants (17 males and 8 females). Vertical jump performance was assessed and classified using standardized norms. Descriptive statistical analyses were used, including minimum–maximum values, mean, and standard deviation, along with frequency and percentage distribution. The explosive power of the group was categorized in the Moderate classification, with a mean score of 3.12 (on a 1–5 scale) and a standard deviation of 0.726, indicating high homogeneity. Most participants (48%) were in the Moderate category, followed by 32% in the Good category and 20% in the Less category. No participant achieved the Excellent classification. The overall explosive power profile of Unsika Sports Science student-athletes in 2025 is at a Moderate level, suggesting the need for strengthened physical conditioning programs to enhance vertical jump performance.
