Brief Summary

This study employed a single-group repeated measures design, conducted in accordance with the STROBE reporting guidelines. Nineteen participants who met the inclusion criteria were recruited. All assessments were performed individually in a quiet, controlled environment to minimize external distractions. Participants were instructed to avoid intense physical activity, caffeine consumption, and to wear appropriate sports attire for at least 48 hours prior to testing.

Upon arrival, participants rested in a seated position while demographic data were collected. Each test procedure was explained both verbally and visually, and participants were allowed to perform a practice trial to ensure comprehension. A crossover design was used to counterbalance the order of conditions (hands on hips vs. hands free), which was randomly assigned. Repeated measurements were conducted 24 hours after the initial assessments, at the same time of day, to control for diurnal variation. Detailed descriptions of the tests performed are provided in the following sections.

Intervention Type: OTHER

The study design was a single-group repeated measures design. Nineteen individuals meeting the inclusion criteria were included. The assessments were conducted individually in a quiet environment, isolated from other athletes and external factors. Athletes were instructed to refrain from intense exercise and training, avoid caffeine consumption, and attend the assessment in sportswear within the last 24 hours. Upon arrival for the assessments, athletes were seated to rest while demographic information was collected. Each test was explained verbally and visually, and participants were allowed to perform a trial. A crossover design method was used in the study, with the order of tests (hands on hips or hands free) determined randomly. Retest measurements were conducted 24 hours after the initial test at the same time of day. The tests performed are described below.
