Emotion regulation means managing emotional reactions, especially negative emotions.
Many people experience strong feelings after stressful or upsetting situations, so the ability to control those reactions can support mental health and daily functioning.
Researchers in a 2026 study focused on two emotion regulation strategies.
Cognitive reappraisal means thinking about a negative situation in a less emotional way.
Expressive suppression means controlling visible emotional reactions, such as facial expressions or outward signs of distress.
A key finding was that moderate aerobic exercise helped participants regulate negative emotions more effectively.
Study Overview
Researchers designed the study around a small group of young adults who had limited recent exercise experience.
Forty-three undergraduate students took part in the study, giving researchers a sample that was fairly balanced by sex and focused on a narrow age range.
Selecting low-activity, non-athlete students helped researchers study how one session of moderate aerobic exercise could affect people who were not already adapted to regular training. Since participants had not exercised consistently for at least 2 years, any immediate change after cycling was less likely to be tied to a strong athletic background. Participants completed emotion regulation tasks both before and after the exercise session. Using tasks before and after cycling allowed researchers to compare each person’s performance across two time points. During the tasks, participants viewed neutral images and negative images. Neutral images provided a baseline emotional condition, while negative images were used to create unpleasant feelings. Participants then used different strategies during negative-image trials, including cognitive reappraisal and expressive suppression. Cognitive reappraisal required participants to rethink a negative image in a less emotional way. Expressive suppression required participants to control visible emotional reactions. By comparing these two strategies, researchers could examine how exercise affected different forms of emotion regulation. Related clinical approaches, such as EMDR therapy Spokane, also focus on helping people process distressing emotional material and reduce the intensity of difficult emotional responses. Each participant completed one structured aerobic exercise session on a cycle ergometer. Researchers used cycling because it allowed control over intensity and timing, which made the exercise session easier to standardize across all participants. A warm-up gave participants time to prepare physically before the main exercise period. Moderate-intensity cycling then gave them enough aerobic activity to create a measurable effect without pushing them into overly intense exercise. A cool-down helped bring the session to a gradual end. Researchers also measured brain activity during the tasks using fNIRS. Functional near-infrared spectroscopy tracks oxygenated blood flow in the brain. Higher or lower blood flow can help show how strongly certain brain areas are working during a task. Prefrontal cortex activity was especially important because that area is closely connected to emotional control. Measuring brain activity during the image tasks gave researchers more than self-reported ratings alone. It allowed them to connect changes in emotional experience with changes in brain effort during regulation. Now, what are the main findings of the research? Participants reacted differently to neutral and negative images. Negative images produced stronger unpleasant feelings than neutral images, which showed that the image materials worked as intended. That result mattered because researchers needed to confirm that the task created a real emotional challenge. Without a clear difference between neutral and negative images, it would have been harder to judge changes in emotion regulation after exercise. After moderate cycling, participants reported lower unpleasantness during cognitive reappraisal. Ratings changed from 29.29 before exercise to 22.41 after exercise. Lower unpleasantness after exercise suggests that participants were better able to rethink negative images in a less emotional way. Exercise did not make the negative images neutral. Instead, it appeared to help participants use cognitive reappraisal more effectively. Unpleasantness ratings also decreased when participants used expressive suppression. Ratings changed from 35.43 before exercise to 27.82 after exercise. Although expressive suppression focuses on controlling outward emotional reactions, participants also reported less unpleasantness after exercise. That suggests moderate cycling may have improved their ability to manage emotional responses during a difficult task. Results suggest that participants became more effective at controlling emotional reactions after the cycling session. Because expressive suppression can require mental effort, lower unpleasantness after exercise may indicate better control during negative emotional situations. No significant changes appeared when participants simply viewed neutral or negative images. That detail is important because it separates emotional reaction alone from emotional regulation ability. If exercise had simply reduced all negative emotion, ratings would likely have dropped during simple viewing as well. Instead, major changes appeared during the regulation strategies. In other words, exercise seemed to improve how participants managed negative emotions, not erase negative emotions themselves. Researchers interpreted that pattern as improved neural efficiency. Neural efficiency means participants may have needed less brain effort to complete the regulation task after exercise. Since expressive suppression can demand control and attention, reduced activation may suggest that the brain handled the task more efficiently after moderate cycling. Self-reported ratings and brain activity pointed in the same direction. Participants felt less unpleasantness during regulation tasks, and brain data suggested more efficient control during expressive suppression. A related 2026 review supports the study by describing several ways aerobic exercise can help emotion regulation. Rather than focusing only on one explanation, the review described multiple pathways that may connect aerobic activity with emotional health. Neurobiological mechanisms may involve changes in brain systems connected to mood, stress, and control. Psychological and behavioral changes may include improved confidence, better coping habits, and stronger routines. Social support may matter when exercise occurs with peers, groups, or encouraging environments. Broader research also connects moderate and regular aerobic exercise with better mental health. Reported benefits include reduced depression, anxiety, and stress. Aerobic exercise can also improve cognitive function, self-esteem, and overall well-being. Such findings fit well with the study because emotion regulation is closely tied to mental health. People who regulate negative emotions more effectively may handle stress more successfully and recover better after unpleasant experiences. Moderate aerobic exercise may be especially useful because it is more accessible than intense training. Activities such as cycling, brisk walking, swimming, or using an elliptical machine can often be adjusted to a moderate level. For many people, moderate activity may feel manageable enough to repeat regularly. Regular practice matters because repeated aerobic exercise may build stronger emotional and psychological benefits over time. Together, the study and broader research suggest that aerobic exercise may be a practical, non-drug approach for supporting emotional health. Moderate cycling helped participants manage negative emotions more effectively in a controlled research setting, while broader research links regular aerobic exercise with lower depression, anxiety, and stress. A careful takeaway is that exercise should not be viewed as a cure that removes negative emotions. A better interpretation is that moderate aerobic exercise may strengthen the ability to manage those emotions, especially when paired with healthy routines and consistent practice. One 30-minute session of moderate cycling helped participants regulate negative emotions more effectively. Cognitive reappraisal ratings improved, with unpleasantness decreasing from 29.29 to 22.41. Expressive suppression ratings also improved, with unpleasantness decreasing from 35.43 to 27.82. Exercise did not erase negative emotions. Instead, it helped participants manage those emotions more effectively during regulation tasks. Overall, moderate aerobic exercise may be a simple and useful tool for strengthening emotion regulation and supporting mental health.
