Energy balance

Maximal heart rate was significantly higher during the increasing speed protocol (PSP) compared to the increasing elevation protocol (PIP) or the MST.

Higher heart rates during PSP suggest it may be a more intense protocol for assessing cardiovascular fitness.

StrongSupportsmedium confidence
Maximal heart rate was significantly higher (p < 0.01) during PSP compared to that in either PIP or MST.
