The previous study revealed that HIPT could increase cardiovascular fitness and decrease body fat, but it lacked effective evidence for power and muscle strength, especially in weightlifter. The aim of this study was to determine the effects of 4-week HIPT on performance in weightlifters. Method: Eight college weightlifters participated in this study. All subjects were randomly assigned to two group, traditional resistance training group (TRT, n = 4), or HIPT (n = 4). Both groups trained 3 days a week for 4 weeks. Both groups were measured snatch performance, dynamic mid-thigh pull, maximum strength, jumping ability, isokinetic strength and position control on week 0 and week 5. Result: The result showed that there was no significant between two group. HIPT significantly decreased on average RFD of snatch, average RFD of MTP, peak power and moving distance on jumping ability, but significantly increased isokinetic strength and thigh muscle mass in post-test. TRT significantly decreased on average RFD of snatch, but significantly increased isokinetic strength and body fat mass in post-test. Conclusion: Present result showed that after 4-week HIPT decreased power performance, but also increased muscle mass. Therefore, there was no difference between each training group. We suggested that coaches could use different training methods for different periods and needs.
