AB  - BACKGROUND: High-intensity interval training (HIIT) has been proposed as a 
      time-efficient exercise format to improve exercise adherence, thereby targeting 
      the chronic disease burden associated with sedentary behaviour. Exercise mode 
      (cycling, running), if self-selected, will likely affect the physiological and 
      enjoyment responses to HIIT in sedentary individuals. Differences in 
      physiological and enjoyment responses, associated with the mode of exercise, 
      could potentially influence the uptake and continued adherence to HIIT. It was 
      hypothesised that in young sedentary men, local and systemic oxygen utilisation 
      and enjoyment would be higher during a session of running HIIT, compared to a 
      session of cycling HIIT. METHODS: A total of 12 sedentary men (mean +/- SD; age 24 
      +/- 3 years) completed three exercise sessions: a maximal incremental exercise test 
      on a treadmill (MAX) followed by two experiment conditions, (1) free-paced 
      cycling HIIT on a bicycle ergometer (HIITCYC) and (2) constant-paced running HIIT 
      on a treadmill ergometer (HIITRUN). Deoxygenated haemoglobin (HHb) in the 
      gastrocnemius (GN), the left vastus lateralis (LVL) and the right vastus 
      lateralis (RVL) muscles, oxygen consumption (VO(2)), heart rate (HR), ratings of 
      perceived exertion (RPE) and physical activity enjoyment (PACES) were measured 
      during HIITCYC and HIITRUN. RESULTS: There was a higher HHb in the LVL (p = 
      0.001) and RVL (p = 0.002) sites and a higher VO(2) (p = 0.017) and HR (p < 
      0.001) during HIITCYC, compared to HIITRUN. RPE was higher (p < 0.001) and PACES 
      lower (p = 0.032) during HIITCYC compared to HIITRUN. DISCUSSION: In sedentary 
      individuals, free-paced cycling HIIT produces higher levels of physiological 
      stress when compared to constant-paced running HIIT. Participants perceived 
      running HIIT to be more enjoyable than cycling HIIT. These findings have 
      implications for selection of mode of HIIT for physical stress, exercise 
      enjoyment and compliance.
