Relative Strength and Segment Ratios as Correlates of Countermovement Jump Kinematics: Different Patterns in Male and Female Athletes
Description
This dataset contains anthropometric, strength, and biomechanical data collected from 36 collegiate athletes (16 males, 20 females) from university basketball, volleyball, American football, and flag football teams. The data was gathered to investigate the associations between countermovement jump (CMJ) kinematics, gym-based relative strength, and segment proportions, as well as to identify sex-specific movement strategies (knee-dominant vs. hip-dominant). The dataset includes aggregated physical characteristics, segment ratios, dynamic strength maximums (5RM), and calculated lower-body kinematic ranges of motion during the eccentric and concentric phases of the CMJ. To ensure participant anonymity in compliance with ethical guidelines for human subjects research, all identifiable information, including specific dates of birth, has been removed. Participant age at the time of testing has been calculated and retained.

Steps to reproduce
Data collection was completed in two separate sessions: Anthropometrics & Kinematics: Anthropometric variables were measured using a stadiometer, bioelectric impedance analysis (TANITA MC-780MA), and a sliding caliper via palpation of bony landmarks. CMJ kinematics were captured at 100Hz using a wearable inertial measurement unit (IMU) system (Xsens Awinda) configured for the "Lower Body with Sternum". Participants performed CMJs with hands akimbo. Strength Testing: Conducted in a university gymnasium, participants completed 5-repetition maximum (5RM) tests for unilateral leg extensions (stronger leg) and barbell hip thrusts to assess knee and hip extensor strength, respectively. Kinematic variables (joint angles, center of mass drop percentage) were calculated exclusively during the eccentric and concentric phases of the jump using Xsens MVN software. Relative strength was calculated by dividing the 5RM load by total body weight.
