What the study found
The study did not detect differences in fitness improvements between fifteen-second and thirty-second sprint intervals or continuous endurance training, despite different numerical changes.
Participants and protocol
Thirty-six healthy men trained on bicycles three times weekly for four weeks in three exercise groups.
What this cannot establish
A short study with no detected difference is not proof that all formats are equivalent. All-out cycling intervals should not be translated into an unscreened beginner running programme.
