Abstract :The purpose of this study was to compare the effects of loaded whole body static squat exercise during whole body vibration and non-vibration schemes on countermovement jump insert ignore into journalissuearticles values(CMJ);, speed and agility. Twenty-one healthy male college football players insert ignore into journalissuearticles values(age: 20.14 ± 1.65 years; body height: 179.9 ± 8.34 cm; body mass: 74.4 ± 13.0 kg; % body fat: 9.45 ± 4.8); participated in the study. They underwent a standardized general warm-up and dynamic stretching followed by randomized loaded protocols executed for 5 minutes with a rest interval of 30 seconds. These included static squat with 30% bodyweight external load insert ignore into journalissuearticles values(ST + 30%);, ST + 30% on a vibration platform at 25 Hz and 2 mm insert ignore into journalissuearticles values(WBV25);, and  ST + 30% on a vibration platform at 50 Hz and 4mm. Measurement of  CMJ, 15 m sprint and modified agility tests followed the warm-up protocol. One way repeated measures ANOVA revealed a significant difference on CMJ performance, Finsert ignore into journalissuearticles values(2,40); = 24.5, partial Î·2 =  .551, p < 0.01. Bonferonni post hoc showed that ST+30% posted significantly lower CMJ than WBV25 and WBV50. CMJ at WBV50 was higher than WBV25. There was a significant difference on speed, F insert ignore into journalissuearticles values(2, 40); = 23.6, partial η2  = .542, p < 0.01. Post hoc determined that ST+30% was significantly slower than WBV25 and WBV50. WBV50 was faster than WBV25. There was a significant difference in the agility among interventions, F insert ignore into journalissuearticles values(2, 40); = 18.2, partial η2 = .477, p < 0.01. ST+30% agility time was significantly higher compared to WBV25 and WBV50.  In conclusion, WBV50 posted the greatest benefits in CMJ, speed and agility.
