Instability resistance training techniques are commonly used to increase athletic performance. The purpose of the present study was to analyze the effects of performing the squat exercise with suspended weight within a six-week resistance training program on dynamic balance, maximal strength, agility, and power in collegiate male athletes. Thirty-two male collegiate baseball players were randomly assigned to suspended (experimental) or conventional (control) training groups and completed 1RM squat, dynamic balance, vertical jump, and agility tests before and after a six-week resistance training program. The only difference between otherwise identical programs was the suspended group’s use of suspended loading on the barbell in the squat exercise. Post-test data revealed significant 1RM squat increases in the suspended (6.9%) and conventional (4.5%) groups, but no significant changes in balance. Although statistically insignificant, vertical jump changed by +2.27% and -0.70% and agility by +1.23% and +1.00% in the suspended and conventional groups, respectively.
