Why the study?
The impact of warm-up intensity and duration before maximal effort cardiopulmonary exercise testing remains uncertain.
Does a 5- or 10-minute warm-up at low or moderate intensity improve maximal oxygen consumption during cardiopulmonary exercise testing in healthy young adults compared to no warm-up?
Does a 5- or 10-minute warm-up at low or moderate intensity improve maximal oxygen consumption during cardiopulmonary exercise testing in healthy young adults compared to no warm-up?
Performing a warm-up before maximal effort cardiopulmonary exercise testing does not significantly alter peak oxygen uptake, heart rate, or power output in healthy young adults.
Questions need for warm-up before CPET; hypothesis-generating and should not yet change practice.
The impact of warm-up intensity and duration before maximal effort cardiopulmonary exercise testing remains uncertain. Herein, we investigated the effect of a 5- versus 10-min warm-up performed at low or moderate intensity on maximal oxygen consumption. Compared with no warm-up, these different warm-ups yielded similar peak oxygen uptake, peak heart rate, and peak power output, thereby challenging the conventional notion that a warm-up is needed to optimize cardiopulmonary exercise testing.
