Little is known about the acute affective response to physical activity in people with depression, which may have implications for acute symptom management and may also be a mechanism that explains the antidepressant effects of physical activity. This study aimed to quantitatively synthesize existing research on the acute affective response to physical activity in people with depression. Five online databases were searched to July 2021 to identify studies that examined pre-post changes in affective states following a bout of moderate-to-vigorous physical activity in people with depression. The affective response to physical activity was synthesized using a random-effects meta-analysis with a robust variance estimator. A total of 18 studies were included in the meta-analysis. Results showed that people with depression experienced a favourable affective response following an acute bout of physical activity (SMD = 0.585, 95% confidence interval = [0.456, 0.714], 95% prediction interval = [−0.079, 1.249]). Moderator analysis indicated this effect was consistent across different types of affective states, exercise conditions, and participant characteristics. Additionally, results were robust to changes in the study protocol and publication bias. Only within-person pre-post changes in affective responses were examined. No comparisons were made with control conditions. Acute bouts of physical activity can significantly improve affective states in people with depression. Future research should examine the effect of physical activity on affective states in non-experimental settings and examine whether the affective response to physical activity is a predictor of the long-term antidepressant effects of physical activity interventions. •People with depression experience a favourable affective response to physical activity.•Results were not moderated by type of affective state or exercise/sample characteristics.•Results were robust to changes in protocol and publication bias.•Future studies need to replicate results in non-experimental settings.
