Immersive video of natural scenery increases exercise enjoyment without compromising intensity during affect-regulated cycling
摘要
Exercise at high intensities is often associated with unpleasant sensations which may reduce adherence. However, maintaining a subjectively pleasing or good feeling during exercise may limit work rate and resulting long-term physiological adaptation. External stimuli, such as music or a distracting visual environment, may reduce feelings of discomfort during exercise and enable a higher work rate at a given affective state. Whether the use of immersive video (IV) can benefit work rate during affect-regulated exercise, specifically, is unknown.
AimsThis study aimed to determine if the addition of IV to an affect-regulated bout of exercise impacted power output, heart rate (HR), and perceptual responses.
MethodsIn a repeated-measures crossover manner, healthy young adults (N = 27, 9 males/18 females, Mage = 19.9 ± 1.0 years, Mbodyfat = 23.0 ± 8.8%) completed two 20-min exercise sessions on a cycle ergometer, self-adjusted to a Feeling Scale value of + 3 (feeling “good”): an IV condition displaying a bike ride in natural scenery, and a Control condition with a physical laboratory setting visible. Average power output and HR, along with rating of perceived exertion (RPE) and affective valence (Feeling Scale), were collected every 5 min. Physical activity enjoyment was assessed post-exercise. Repeated-measures analyses were used as appropriate (alpha = 0.05).
ResultsThere was no difference between conditions, at matched time points or overall, for power output, HR, or RPE. Enjoyment was higher following the IV condition than the Control condition (107.51 ± 14.10 vs. 94.07 ± 18.38; p ≤ 0.001, d = 0.73).
ConclusionsParticipants asked to select and maintain an intensity that made them feel “good” produced the same overall work rate and HR with IV as in a Control condition. Enjoyment was rated higher after the IV condition which could have implications for exercise adherence.
