What the study found
Both training groups improved aerobic fitness similarly, while their patterns of cardiorespiratory coordination changed differently.
Participants and protocol
Twenty adults were randomized to six weeks of work-matched interval or continuous cycling training. Researchers analysed relationships among physiological signals during maximal tests.
What this cannot establish
The exploratory coordination analysis does not show that one programme improves race performance more than the other or provide a validated consumer training-selection test.
