Abstract

Purpose: The aim of the study was to investigate the effects of acute passive stretching on O2 uptake (V˙O2) vs work rate slope during a continuous incremental ramp exercise. Methods: On two different occasions, eight participants (age 23 ± 3 years; stature 1.71 ± 0.10 m; body mass 68 ± 8 kg; mean ± SD) performed two maximum incremental ramp tests on a cycle ergometer (25 W/min), with and without pre-exercise stretching. During tests, we measured V˙O2 and other metabolic and cardiorespiratory parameters on a breath-by-breath basis. The V˙O2 vs work rate slopes were calculated below (S1) and above (S2) the first ventilatory threshold (VET1). Results: With stretching: (1) peak V˙O2 did not change, while peak work rate decreased (P 1, S2 was steeper by about 11 % (P 2 vs work rate relationship above VET1 (S2), without affecting peak V˙O2. The present findings have practical implications, questioning the use of stretching manoeuvres especially when peak work rate plays a key role in exercise performance.
