Participants completed five randomized experimental conditions: maximal voluntary isometric contraction (MVIC), dynamic contraction (DC), MVIC+EMS, DC+EMS, and EMS only (O-EMS). Baseline and post-intervention assessments included countermovement jump (CMJ), countermovement jump with arm swing (CMJWH), zig-zag agility, and shooting speed, with post-tests conducted after a 4-minute recovery period. Perceptual responses, including ratings of perceived exertion (RPE), perceived discomfort (RPD), and fatigue (VAS), were recorded immediately after each protocol. All sessions were conducted between 14:00 and 16:00 under standardized conditions, with protocol order randomized and participants instructed to avoid strenuous exercise and food intake before testing.",[29,30,31],"Soccer","Performance","Contraction",[33,34,35,36],"isometric contraction","dynamic contraction","squat","PAPE","NOT_YET_RECRUITING","2026-07-06",{"date":40,"type":41},"2026-07-10","ACTUAL",{"date":43,"type":23},"2026-08-01",{"date":45,"type":23},"2026-09-05",{"name":47,"class":48},"Karabuk University","OTHER"]
