Brief Summary:
Previous research is equivocal concerning if high intensity interval training is viewed as more aversive versus moderate exercise. Our data in active men and women showed that interval training is viewed as more enjoyable than higher volume moderate exercise.

Condition or disease Intervention/treatment
Exercise Training Other: Exercise intensity

Detailed Description:
Twelve men and women who were habitually active initially performed ramp exercise on a cycle ergometer to assess maximal oxygen uptake (VO2max) and peak power output (PPO), which was used to determine workload for the subsequent 2 bouts. They returned at least 48 h later at the same time of day to complete high intensity interval training (HIIT consisting of repeated 1 min bouts at 85 %PPO) or moderate intensity continuous training (MICT consisting of 25 min at 40 %PPO). During exercise, heart rate, oxygen uptake, perceived exertion, pleasure:displeasure, and blood lactate concentration were continuously assessed. Ten minutes post-exercise, physical activity enjoyment was measured. Data showed that despite higher oxygen uptake, heart rate, blood lactate concentration, and perceived exertion in HIIT, enjoyment was higher in HIIT versus MICT.

Group/Cohort Intervention/treatment
Active men and women
Healthy, active men and women ages 18-45 yr completed 1 bout of high intensity interval training and moderate intensity continuous training in a randomized, crossover design.
Other: Exercise intensity
Participants were randomized to 1 or 2 exercise intensities, moderate or high (interval training).

Primary Outcome Measures :
  1. Physical activity enjoyment score (PACES) [ Time Frame: This was measured 10 min post-exercise in all participants during the 3 mo of data collection. ]
    This is an 18-item categorical survey used to assess participants' enjoyment of the bout of physical activity that was just completed

  2. Oxygen uptake [ Time Frame: Measured continuously during exercise during the 3 mo of data collection. ]
    Oxygen uptake (VO2) represents mitochondrial consumption of oxygen to drive cellular metabolism generating ATP to support muscular contraction.
