Popis: Objective To evaluate and compare the effects of high-intensity interval training (HIIT) varying in exercise intensities to traditional endurance training (TET) on physiological and performance adaptations in trained female inline speed skaters. 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 V ˙ O 2 max ( 100 % v V ˙ O 2 max ) (H100, N = 7), 115 % v V ˙ O 2 max (H115, N = 7), and 130 % v V ˙ O 2 max (H130, N = 7), 1:3 work to recovery ratio; and/or TET group (N = 7): 60-minute running at 75 % v V ˙ O 2 max three sessions per week. Results Significant (except as shown) improvements (p V ˙ O 2 max (H100 = +7.6%, H115 = +6.1%, H130 = +0.1%; p = 0.4), v V ˙ O 2 max (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 V ˙ O 2 max , v V ˙ O 2 max , PPO, MPO, 3000 m skating performance, and Tmax in trained female inline speed skaters.
