Summary

Regular exercise is needed to ensure good general health and wellbeing. How exercise makes you feel (pleasant / unpleasant) is thought to be important for whether people will stick with a given exercise routine. Sprint interval training (SIT) has been shown be a time-efficient exercise strategy for improving health, but some researchers suggest that SIT may be experienced as unpleasant and therefore unsuitable as an exercise routine for improving general health and wellbeing. However, SIT protocols are diverse, and it has previously been shown that very short SIT protocols such as 'reduced-exertion high-intensity interval training' (REHIT) are not perceived as unpleasant, at least on average. Interestingly, how REHIT is perceived appears to be highly variable between individuals. This individual variability may have important implications for whether people stick with REHIT and/or SIT in real-world settings, and therefore it is important to characterise it and better understand why some people find this exercise unpleasant while others do not. This study aims to characterise the within-participant and between-participant variability in how people perceive REHIT. Furthermore, potential relationships between psychological characteristics and how people perceive REHIT will be explored.

REHIT

REHIt involves 10 minutes of unloaded cycling on a stationary bike, interspersed with two 20-s 'all-out' cycle sprints against a resistance equivalent to 7.5% of body mass.
