About this study
Official title: Motor Imagery Ability, Hand Mental Rotation and Performance Outcomes in Female Volleyball Players: A Comparative Cross-sectional Study
This comparative cross-sectional study investigates the relationship between motor imagery (MI) ability, hand mental rotation (HMR), and performance outcomes in female volleyball players. Volleyball is a high-speed, cognitively demanding sport requiring precise motor coordination, rapid decision-making, and explosive movements. MI-the mental simulation of movement-and HMR-the cognitive manipulation of hand orientation-are critical for motor planning and execution. The study has two primary objectives: (1) to compare MI ability and HMR performance between female volleyball players and sedentary controls, and (2) to evaluate associations between MI/HMR scores and reaction time as well as vertical jump performance among volleyball players. The investigators hypothesize that volleyball players will exhibit superior MI and HMR abilities compared to controls, and that higher MI and HMR scores will correlate with faster reaction times and greater vertical jump height. Findings from this study will elucidate the cognitive-motor mechanisms underlying athletic performance and may inform training strategies to enhance neuromotor efficiency in sport-specific contexts.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Female Volleyball Players | Female athletes currently participating in competitive volleyball; no intervention applied. | |
| Controls Group | Female individuals not engaged in regular physical activity; no intervention applied. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mental Chronometry Test
Mental chronometry ratio calculated as |Actual Time - Imagined Time| / Actual Time, measured during five actual vertical jumps and five imagined vertical jumps. Lower values indicate better motor imagery performance. Time measured in seconds using a stopwatch; ratio is unitless.
Measured: Baseline (single assessment during the initial study visit)
Secondary outcomes (3)
Hand Mental Rotation Task
Mean response time (milliseconds) for left/right hand discrimination tasks in the Orientate® application. Lower values indicate faster cognitive processing related to mental rotation.
Measured: Baseline
Reaction Time (ms)
Mean reaction time across three trials measured using the BlazePod® wireless LED sensor system. Participants respond to visual stimuli with their dominant hand. Lower values indicate better reaction performance.
Measured: Baseline
Vertical Jump Height (cm)
Mean jump height calculated from three countermovement jumps recorded and analyzed using the My Jump 2 smartphone application. Higher values indicate better lower-limb explosive performance.
Measured: Baseline
