Intense exercise is well-established as a methodology for improving metabolic health and performance parameters, both via continuous and high-intensity interval training (HIIT). Research to date has demonstrated that more intense exercise tends to produce less favorable affective and enjoyment responses but the relationship between these two variables has not been established.

PURPOSE: Assess the relationship between affective and enjoyment responses during HIIT and moderate continuous exercise among overweight and insufficiently active adults.

METHODS: 48 overweight-to-obese participants (mean BMI = 28, mean VO2 peak = 29 ml/kg/min) completed four counterbalanced trials comprised of a 30-minute continuous trial at 33% peak power (CONT) and three 20-minute interval trials that alternated between 85% and 15% peak power using 1:1 work-to-recovery ratios: 15 secs (HIIT-15), 30 secs (HIIT-30), and 60 seconds (HIIT-60). Affect was measured using the Feeling Scale (FS) and enjoyment was measured using the Exercise Enjoyment Scale (EES).

RESULTS: Data was submitted to RM ANOVA and correlational analyses. Findings indicated that affect and enjoyment declined during HIIT-60 but was preserved during all other trials. All correlations for assessments taken at the same point during exercise were significant (p < 0.05) ranging from 0.31 to 0.70. Inspection of the correlation values indicate that the correlation decreased during the CONT trial (0.62 to 0.31) but remained relatively constant for all three HIIT trials. Additionally, correlations were slightly higher in the HIIT-60 trial than other HIIT trials.

CONCLUSIONS: Findings indicate that correlations between affect and enjoyment are strong during HIIT and continuous moderate exercise. The finding that correlations decreased over time during the moderate continuous condition suggests a dissociation between the processes that underlie affect and enjoyment. Likewise, the maintenance of similar correlations throughout all of the HIIT trials suggests that within this particular exercise context that the underlying processes are not considerably unique. Collectively, the findings indicate that HIIT produces affective and enjoyment responses that are generally positive and therefore appropriate for overweight, sedentary populations.
