This study aims to investigate the effects of blood flow restriction (BFR) applied during jump squat exercises on selected performance parameters in elite volleyball players. Prior to each training session, all participants followed a standardized warm-up protocol that included dynamic stretching, mobility exercises, and general body activation to prepare for the workout. Following this preparation phase, the jump squat exercises were performed. Participants were randomly assigned to two groups. The experimental group performed the jump squats under blood flow restriction using a manually controlled, non-automated tourniquet, while the control group performed the same exercises without any restriction. Performance parameters were assessed before and after the 4-week intervention using the following measurement tools: Jump performance: Measured using the Optojump system Agility: Assessed with the Hexagon Agility Test Balance: Evaluated using the Y Balance Test Perceived fatigue: Measured via the Borg Rating of Perceived Exertion (RPE) scale The purpose of the study is to determine whether jump squat exercises performed under BFR conditions can lead to greater improvements in athletic performance and perceived fatigue compared to traditional training methods. The study was conducted using equipment provided by Bahçeşehir University and included licensed volleyball players from Süreyyapaşa Sports Club. The research protocol was approved by the Non-Interventional Research Ethics Committee of Üsküdar University.
