文摘

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 ($\dot{V}{\text{O}}_{2\text{peak}}$) and ventilatory threshold (VT) in male well-trained canoe polo athletes.

Methods

Several aspects of $\dot{V}{\text{O}}_{2\text{peak}}$ and VT were measured after two different training programs performed for 3 weeks. Following the pre-test, 21 well-trained male canoe polo athletes ($\dot{V}{\text{O}}_{2\text{peak}}$ for arms = 38.1 ± 4.7 mL/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) × 60 seconds (s) at the paddling speed associated with $\dot{V}{\text{O}}_{2\text{peak}}$ (f451b90c3a41a70cd5203fa42307e">$v\dot{V}{\text{O}}_{2\text{peak}}$), 1:3 work to recovery ratio; group 2 (G₂), n = 7; 6 × 60 s at (100,110,120,130,130, 130,120,110,100)% f451b90c3a41a70cd5203fa42307e">$v\dot{V}{\text{O}}_{2\text{peak}}$ from 1st to 9th session respectively, 1:3 work to recovery; group 3 (G_CON), n = 7, the control group performed three sessions 60 minutes (min) paddling (75% f451b90c3a41a70cd5203fa42307e">$v\dot{V}{\text{O}}_{2\text{peak}}$) per week.

Results

Significant (except as shown) improvements (P < 0.05) following HIIT were found in: $\dot{V}{\text{O}}_{2\text{peak}}$ (G₁ = +6.7%, G₂ = +7.6%), f451b90c3a41a70cd5203fa42307e">$v\dot{V}{\text{O}}_{2\text{peak}}$ (G₁ = +8.4%, G₂ = +9.4%), and $\%\dot{V}{\text{O}}_{2\text{peak}}$ at VT (G₁ = +16.1%, G₂ = +6.2%; P = 0.19), but no significant differences were found in $\dot{V}{\text{O}}_2/{\text{HR}}_{\text{peak}}$ (G₁ = +3.2%; P = 0.39, G₂ = +2.6%; P = 0.57) and HR at $\dot{V}{\text{O}}_{2\text{peak}}$ (G₁ = +3.1%; P = 0.24, G₂ = +3.2%; P = 0.07). Also, no significant changes in these variables were found in the G_CON. Present findings suggest that 3 weeks of high-intensity interval training program with low volume (almost 6 or 9 min per session) is associated with improvements in $\dot{V}{\text{O}}_{2\text{peak}}$, f451b90c3a41a70cd5203fa42307e">$v\dot{V}{\text{O}}_{2\text{peak}}$, and $\%\dot{V}{\text{O}}_{2\text{peak}}$ at VT in well-trained canoe polo athletes.
