Purpose: Lower extremity strength is crucial for the sport of gymnastics. Female gymnasts require explosive strength, quick speed, and flexibility for high competition performances. Muscular function is used to monitor fitness during preseason training to prepare athletes for in-season competitions. The primary focus of the CMJs is during propulsive phase which is the moment when an athlete propels themselves upwards into the air, creating an explosive jump. This motion measures force production and force transfer efficiency. The purpose of this study was to examine lower extremity strength of women gymnasts during 8 weeks of preseason training. Methods: Eighteen NCAA Division III women’s gymnasts (age 19.44±1.2 years, height 163±4.55 cm, body mass 62.2±4.73 kg) tested twice weekly. Each test session included three CMJs with hands on hips with feet shoulder width apart. Two portable force platforms (Hawkin, sample rate: 1000 Hz) were used to collect vertical ground reaction forces (GRF). The kinetic output of Peak Relative Propulsive Force (PRPF) and kinematic outputs of Time to Takeoff (TTT) and Takeoff Velocity (TV) were identified for analysis. Results: Each dependent variable was influenced by Week 1 (PRPF pConclusion:The key metric observed in this study was time to takeoff shown in Table 2. This is a positive indicator of greater explosive power and neuromuscular efficiency. Faster time to takeoff allows for a more efficient use of force during a jump.
