Abstract

Objective: A V˙O₂ slow component V˙O₂ SC typically occurs during continuous, constant work rate exercises conducted at both intense and maximal intensities. The extent to which V˙O₂ SC also develops during intermittent exercises in field condition warrants investigations. This study aimed to test the occurrence of a V˙O₂ SC during a field-based intermittent exercise performed at an intensity that elicits V˙O_{2_peak}. Material and methods: For this purpose, ten male tennis players performed two intermittent field exercises that mimic several aspects of tennis activity: an incremental test to determine their peak rate of oxygen consumption, and a discontinuous, constant work rate exercise (DCWR) conducted at V˙O_{2_peak} intensity until exhaustion. Cardio-respiratory variables were measured breath-by-breath using a portable device. Results: The coefficients of determination of the V˙O₂ kinetics models were 0.74 ± 0.18 (P < 0.001) and 0.40 ± 0.16 (P < 0.001) for the incremental test and DCWR, respectively. During the incremental test, an extra V˙O₂ was detected above a threshold intensity corresponding to 86 ± 6% of V˙O_{2_peak}. During DCWR, the occurrence of the V˙O₂ SC was significant for 6 subjects, with a magnitude of 4.0 ± 3.3 mL.min⁻¹.kg⁻¹ representing 6.0 ± 3.2% of the total V˙O₂ response. Conclusion: This study showed that a mathematical model used to describe V˙O₂ response to an intermittent exercise is appropriate and a V˙O₂ SC was detected for the majority of the participants during intermittent exercises that elicit V˙O_{2_peak}.
