Methods Participants were randomly assigned to one of 3 HIIT groups: 6,8,10 (repetitions/session from 1st to 3rd week respectively) × 60 seconds (s) at the running speed associated with () (H100, N = 7), (H115, N = 7), and (H130, N = 7), 1:3 work to recovery ratio; and/or TET group (N = 7): 60-minute running at three sessions per week. Results Significant (except as shown) improvements (p < 0.05) following HIIT were found in: (H100 = +7.6%, H115 = +6.1%, H130 = +0.1%; p = 0.4), (H100 = +10.3%, H115 = +6.3%, H130 = +9.8%), peak power output (PPO) (H100 = +10.3%, H115 = +9.1%, H130 = +5.5%; p = 0.2), mean power output (MPO) (H100 = +22.6%, H115 = +24.1%, H130 = +21.9%), 3000 meter (m) skating performance (H100 = −15.2%, H115 = −7.9%, H130 = −10.6%), and Tmax (H100 = +39.4%, H115 = +5.0%; p = 0.5, H130 = +17.8%; p = 0.1). No significant differences were found among groups. Also, no changes in these variables were found in the TET group. Conclusions Present findings suggest that three weeks of HIIT program with low volume (almost 6 or 10 min per session) is associated with improvements in , , PPO, MPO, 3000 m skating performance, and Tmax in trained female inline speed skaters.
