Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Basic Volleyball Skills Performance | Baseline (February 25, 2025) and immediately after completion of the 8-week training program (April 22, 2025). | Basic volleyball skills (finger pass, forearm pass, serve, block, and spike) were assessed before and after the 8-week training program using an observation-based rating procedure developed by three certified volleyball coaching experts. Finger and forearm pass accuracy was evaluated in designated court areas (1, 6, 5 and 2, 3, 4). Serve accuracy was assessed over three attempts toward designated target areas. Block and spike techniques were evaluated in areas 2, 3, and 4 near the net. Each successful attempt meeting the designated target or performance criterion received 5 points, while unsuccessful attempts received 0 points. The same procedure was used at baseline and immediately after the training program. |
| Secondary | Reaction Time | Baseline (February 25, 2025) and immediately after completion of the 8-week training program (April 22, 2025). | Participants' reaction time was assessed before and after the 8-week training program using the BlazePod system with wireless light pods. Participants responded to visual light stimuli as quickly as possible. Reaction-time performance was recorded during the pre-test and post-test assessments to evaluate changes following the training program. |
