Effects of Physical Exercises on Emotion Regulation: A Meta-Analysis

Abstract

BackgroundAt present, there are inconsistent results in the research on the effect of physical exercise on emotion regulation ability, and there is no relevant research on how to exercise scientificlc. Therefore, on the basis of previous research, this study conducted a meta-analysis on the theme of physical exercise affecting emotion regulation ability according to the statement of PRISMA, and added relevant moderator variables to clarify the effect of physical exercise on emotion regulation ability.ObjectiveWe identified physical exercise studies and randomized controlled trials (RCTs) of emotion regulation ability that reported overall effect, heterogeneity, and publication bias of physical exercises on emotion regulation ability.MethodsWe searched for RCT s of exercise interventions on emotion regulation ability from databases including PubMed, Web of Science, Ebsco, The Cochrane Library, CNKI (China National Knowledge Infrastructure), and Wanfang, from January 1 2000 to January 1 2022. We performed methodological quality evaluations on the included literature and graded evidence with a meta-analysis using Review Manager 5.3 software.ResultsIn total, 10 RCT s were included; the overall results of the meta-analysis (936participants) indicated that physical exercises improved emotion regulation ability (standardized mean difference (SMD) = 0.47; 95% confidence interval (CI) 0.21 to 0.72; p < 0.05), sensory arousal ability (SMD = 0.70; 95% CI 0.14 to 1.27; p < 0.05), and emotion regulation strategies (SMD = 0.46; 95% CI 0.04 to 0.87; p < 0.05); Subgroup analysis showed that a single exercise of more than 30 minutes can improve emotional regulation ability, which is not affected by exercise intensity, period and the health status of the participants.ConclusionPhysical exercises can effectively improve the emotion regulation ability. The effects are considered as moderate effect sizes. While single exercise time should be at least 30 minutes.Limited by the quantity and quality of the included studies, the above conclusions need to be verified with more high-quality studies.PROSPERO registration number: CRD42021217978

The Effects of Physical Activity on Emotion Regulation and Executive Function: A Narrative Review

“…Research in adults and older children suggests that physical ac2vity provides both immediate and long-term benefits for emo2on regula2on and execu2ve func2on (Best, 2010;Liu et al, 2022). These findings suggest physical ac2vity may offer an effec2ve in-themoment tool to address emo2on dysregula2on in early childhood and enhance overall regula2on skills with prolonged use.…”

“…While this area of research is in its infancy in early childhood, evidence from research conducted with older children and adults is more abundant and provides moderate evidence that engaging in physical ac2vity offers benefits for emo2on regula2on, and more specifically, provides therapeu2c effects on the autonomic nervous system (Basso & Suzuki, 2017;Berger & Motl, 2000;Davidson et al, 2007;Liu et al, 2022). Evidence from a recent meta-analysis of 11 randomised control trials conducted with adolescents and adults reported that both long-term and acute bouts of physical ac2vity offer benefits for emo2on regula2on; reducing the dura2on of nega2ve affect and levels of sensory arousal in response to a stressor, and increasing the use of emo2on regula2on strategies (Liu et al, 2022).…”

“…There is growing evidence that physical ac2vity supports effec2ve emo2on regula2on. However, this research has primarily been conducted in adults and older children (Liu et al, 2022), with limited considera2on of effects in early childhood (Williams & Berthelsen, 2019). To establish a nuanced understanding of the poten2al effects of physical ac2vity and movement in early childhood, the current review steps through a broad evidence base, paving the way for further experimental research in the area.…”

Neuroplasticity to autophagy cross-talk in a therapeutic effect of physical exercises and irisin in ADHD

“…Numerous studies associate the beneficiary effects of PEs with the upregulation of BDNF, an essential component of neuroplasticity ( Kim et al, 2020 ; Müller et al, 2020 ; Nicolini et al, 2020 ; Park et al, 2020 ; Sugiyama et al, 2020 ), and with the transient increase in the availability of BDNF in the brain ( Knaepen et al, 2010 ; Quan et al, 2020 ; Walsh et al, 2020 ). Since the mechanisms of PEs’ profitable effects may be similar to that of antidepressants ( Björkholm and Monteggia, 2016 ; Castrén and Kojima, 2017 ), it is not surprising that PEs are beneficial in the improvement of regulation of emotional status ( Zhang et al, 2019a ; Liu et al, 2022 ). In addition to altering synapse wiring, PEs can induce neuroplasticity by acting on auxiliary functions that can lead to neuroplasticity, such as glial activation and angiogenesis ( Morland et al, 2017 ; Li et al, 2021 ).…”

Effect of physical exercise on social adaptability of college students: Chain intermediary effect of social-emotional competency and self-esteem

“…Social-emotional competency mainly includes social competency and emotional competency (Choi and Gwag, 2017). Studies have shown that physical exercise has a positive effect on social competency and emotional control skills (Jiang et al, 2018;Liu J. et al, 2022). Lack of socialemotional competency is the root cause of various psychological and behavioral problems, which seriously hinder students' academic progress and the growth of body and mind (Rautakoski et al, 2021).…”
