Effects of abstinence from habitual involvement in regular exercise on feeling states: an ecological momentary assessment study.

ABSTRACT

Regular exercise was experimentally reduced to determine its effects on positive feeling states. Using ecological momentary assessments, 40 participants maintained their regular exercise routine on 3 days and were deprived of their scheduled exercise on 3 other days. They recorded their feeling states, using the Exercise-Induced Feeling Inventory, four times daily as well as prior to and following exercise. Multi-level modelling analyses controlling for diurnal variations in feeling states revealed that positive feeling states were elevated on days when exercise deprivation occurred compared with non-exercise days and when no deprivation manipulation occurred. People with lower exercise dependence symptoms felt better on days when they were deprived from exercise compared with non-exercise days, whereas people with higher exercise dependence symptoms felt about the same when they were deprived from exercise compared with non-exercise days. These findings demonstrate that positive feeling states occur following an acute bout of exercise and that exercise deprivation had a positive impact on feeling states, with the level of exercise dependence symptoms moderating this effect.
