Agha-Alinejad Objective The aim of this study was to evaluate and compare the effects of two different high-intensity interval training (HIIT) protocols on peak oxygen uptake ( V ˙ O 2 peak ) and ventilatory threshold (VT) in male well-trained canoe polo athletes. Methods Several aspects of V ˙ O 2 peak and VT were measured after two different training programs performed for 3 weeks. Following the pre-test, 21 well-trained male canoe polo athletes ( V ˙ O 2 peak for arms=38.1±4.7mL/kg/min) were randomly divided into two training groups (group 1 [G1], n =7; 6,7,8,9,9,9,8,7,6 (repetitions/session from 1st to 9th session respectively)×60seconds (s) at the paddling speed associated with V ˙ O 2 peak ( v V ˙ O 2 peak ), 1:3 work to recovery ratio; group 2 (G2), n =7; 6×60 s at (100,110,120,130,130, 130,120,110,100)% v V ˙ O 2 peak from 1st to 9th session respectively, 1:3 work to recovery; group 3 (GCON), n =7, the control group performed three sessions 60minutes (min) paddling (75% v V ˙ O 2 peak ) per week. Results Significant (except as shown) improvements (P <0.05) following HIIT were found in: V ˙ O 2 peak (G1 =+6.7%, G2 =+7.6%), v V ˙ O 2 peak (G1 =+8.4%, G2 =+9.4%), and % V ˙ O 2 peak at VT (G1 =...
