The objective of this research was to study and compare the effects of Olympic barbell jump squat and hexagonal barbell jump squat training on peak power, peak force, and peak velocity in athletes of Thailand National Sports University, Samutsakhon Campus. The samples were divided into 3 groups, Olympic barbell jump squat training group (experimental group 1, N=9), Hexagonal barbell jump squat training group (experimental group 2, N=9) and Regular training group (control group, N=9). They practiced 2 days a week for 6 weeks.
The results from barbell back squat jump test showed significant improvement in peak power, peak vertical ground reaction force, and Peak barbell velocity in the Olympic barbell jump squat training group (p < 0.05), while the Hexagonal barbell jump squat training group significantly improved in peak power, average power, peak barbell velocity and average barbell velocity (p < 0.05). Barbell dead lift squat jump test showed significant improvement in peak vertical ground reaction force, and average vertical ground reaction force in the Olympic barbell jump squat training group (p < 0.05), while the Hexagonal barbell jump squat training group significantly improved peak power, peak barbell velocity, and average barbell velocity (p < 0.05). The effects of Olympic barbell jump squat training and Hexagonal barbell jump squat training on peak power, peak vertical ground reaction force and peak barbell velocity were not statistically significant differences.
Research findings indicate that Hexagonal barbell jump squat training can develop peak power, peak barbell velocity, and average barbell velocity. While Olympic barbell jump squat training can develop peak vertical ground reaction force.
