Brief summary
This study aims to compare the acute effects of push-up exercises performed under different blood flow restriction (BFR) conditions on upper extremity explosive strength performance, measured via the seated unilateral medicine ball throw test.
Detailed description
The study includes three push-up conditions (BFR, sham BFR, and no BFR). Performance is evaluated via medicine ball throws at the 4th, 8th, and 12th minutes post-exercise. Exercises are applied in a crossover design with 50% limb occlusion pressure (LOP) BFR, sham, and control arms. Throw distance and ball velocity (measured by radar device) are primary outcomes. RPE scale is used to assess perceived exertion.
Interventions
a BFR cuff will be placed on the upper extremity in the same location as in the real BFR group. During the application, the participant will be led to believe that the cuff is being inflated, although no actual pressure will be applied. The participant will see the cuff being wrapped and apparently inflated, but there will be no physical pressure restricting circulation during the exercise. This aims to control the psychological effects (e.g., the belief that something is being applied) on performance
Participants perform push-up exercises without any cuff application. The same repetition and rest protocol is followed
Participants will perform push-up exercises with 50% arterial occlusion pressure applied to their dominant arm. The cuff is inflated before the exercise and maintained throughout 3 sets of 5 repetitions. There is a 2-minute rest between sets.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| throw distance | will be measured immediately after the exercise protocol is completed three times at 4th, 8th, and 12th minutes | Seated unilateral medicine ball throw distance (in cm) - |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Ball velocity (km/h) | will be measured by radar device after completion of the exercise three times at 4th, 8th, and 12th minutes | speed at which a ball travels immediately after being thrown |
| Rating of Perceived Exertion (RPE) | 1 day (will be assessed at the end of the push-up exercise) | will be assessed via Borg Rating of Perceived Exertion Scale (6-20). Borg scale is used o quantify an individual's subjective perception of exercise intensity. It provides a numerical scale, typically ranging from 6 to 20. Higher scores on the scale indicate a greater subjective sense of difficulty or effort perceived by the individual. |
