This trial tests whether adding a light bench press exercise during rest periods between heavy squat sets affects how high competitive basketball players can jump afterward. Half the participants will do squats only, while the other half will also do bench presses during recovery…

This study explores whether a morning session of contrast training—combining heavy lifts with explosive jumps and throws—can enhance judo-specific performance later that afternoon. Competitive judokas aged 18 to 22 will complete the morning workout and then be tested on a judo-sp…

This study looks at whether doing isometric calf raises (holding a contraction without moving) can immediately improve sprinting, jumping, and change-of-direction performance in elite youth soccer players. Twelve male players aged 15-19 will do either the calf exercise or a light…

This study looked at whether taking beta-alanine for four weeks helps trained male cyclists perform better during repeated high-intensity cycling tests. The supplement is thought to help muscles handle acid buildup, which might delay fatigue. Researchers compared beta-alanine to …

This study looked at whether adding isometric strength exercises (like holding a squat against a bar) to an 8-week training program helps youth soccer players jump higher, sprint faster, and get stronger. Forty-one male players aged 15-19 were split into groups doing unilateral (…

This study tested whether a brief, intense isometric exercise could improve jump performance in highly trained male volleyball players several hours later. Fourteen players did either the isometric exercise or a standard warm-up, and their jump height was measured before, 6 hours…

This study looked at whether doing 2-3 heavy half-squats can instantly boost jump height in football players compared to light jogging. Researchers measured muscle speed, size, and nerve signals in 44 healthy male players aged 18-21. The goal is to help athletes choose the best w…
