A recent study from the Federal University of Goiás in Brazil highlights a significant link between physical fitness and the ability to manage stress. The research found that individuals who are less physically fit are at a staggering 775% greater risk of experiencing heightened anxiety and anger when confronted with stressors.
In the study, researchers evaluated 40 healthy adults aged 18 to 40 over two lab sessions. During one session, participants viewed neutral images, while in the other, they were exposed to distressing images, including those depicting violence and accidents. Researchers assessed changes in anxiety and anger levels before and after each session using established psychological scales.
To gauge participants’ fitness levels, the study utilized predicted VO2max, a measure derived from self-reported exercise habits alongside factors such as age, sex, and body size. Participants were then divided into two groups based on their fitness levels: above-average and below-average.
The results revealed a concerning trend. Participants in the below-average fitness group had an odds ratio of 8.754 for escalating from moderate to high anxiety during the unpleasant-image session compared to their above-average counterparts. This dramatic increase underscores how lower fitness levels can lead to a more pronounced spike in anxiety when faced with emotional stressors.
The study also reported similar findings regarding anger. Participants with lower fitness levels exhibited larger increases in state anger after viewing distressing images. Additionally, the researchers measured “anger-out,” a personality trait reflecting outward expressions of anger. Higher predicted VO2max was associated with smaller changes in anger levels during stress, even after accounting for individual personality differences.
Another aspect of the research focused on “everyday anxiety.” The findings indicated that higher predicted fitness correlated with lower trait anxiety across the board, suggesting that regular physical activity may contribute to overall emotional resilience.
While the study offers valuable insights, it’s essential to recognize its limitations. The sample size was relatively small, and the method for estimating fitness relied on self-reported data rather than direct measurement through advanced technology. Furthermore, the stressors used were curated images rather than the unpredictable challenges encountered in daily life. Nonetheless, the implications align with the common understanding that consistent aerobic exercise enhances the body’s capacity to cope with various strains, both physical and emotional.
The authors concluded that “regular physical exercise can be a useful non-pharmacological strategy for anger management.” For those who find themselves easily irritated or overwhelmed, incorporating regular aerobic activities such as brisk walking, cycling, or swimming could be beneficial. Engaging in exercise does not require a complete lifestyle overhaul; even modest increases in physical activity can improve one’s ability to handle stress effectively.
