Abstract
The purpose of this study was to explore the respiratory response of acute interval and continuous exercise (CE) of low and high intensity. Fourteen recreational athletes (7 men and 7 women; VO 2max = 35.7 ± 6.1 mlkg –1min –1) performed a bout of continuous and a bout of interval exercise (IE) both consisted of 5-min cycling at low intensity [80% of the power output (W) of the predetermined gas exchange threshold (GET) (80%W GET)] and 5-min cycling at high intensity {W GET plus the work rate corresponding to 50% of the difference between peak power output (PPO) at oxygen uptake (VO 2max) test and the W GET [W GET + 0.50 Δ(PPO–W GET)]}. CE compared to IE induced significant higher heart rate and ventilation as well as significant higher levels of mouth occlusion pressure for 0.1 s (P 0.1) (P < 0.05) during low and high intensities. Our results indicate that CE stimulates respiration more than IE when the exercise is performed at the same relative intensity.
