Objective: For a cohort of operational firefighters, we assessed the effects of workplace based high intensity interval training (HIIT) on cardiorespiratory fitness.

Methods: Fifteen firefighters performed HIIT or moderate intensity continuous training (MICT) over 4-weeks. Outcomes were peak oxygen uptake (V̇O2peak), time trial performance, and affective (pleasure/displeasure) responses to exercise.

Results: There was an increase in V̇O2peak for both conditions although this did not reach statistical significance (P = 0.06, η2 = 0.26) and time trial performance improved for both groups (2%, P

Conclusion: Results suggest workplace based HIIT improved fitness and performance to a similar magnitude as MICT whilst avoiding overly negative affective responses and could improve occupational health of firefighters, despite reduced time commitment.
