A survey of 420 middle school students in eastern China found that students who reported more physical activity also tended to report better coping habits and higher health-related quality of life.
The findings suggest that the relationship may involve two psychological and behavioral factors: cognitive reappraisal, or changing how a situation is interpreted so it has less emotional impact, and stress self-management, including habits such as rest, relaxation, sleep and pacing.
But the results do not show that exercise caused better coping or wellbeing. All information was collected through one questionnaire at one point in time, so the direction of the relationships remains uncertain.
What the survey found
The researchers distributed 500 paper questionnaires to students in grades 7 to 9 at two secondary schools in Jiangsu Province in April 2026. They retained 420 complete responses, representing 84.0% of the questionnaires distributed.
Students completed measures of physical activity, cognitive reappraisal, stress self-management and health-related quality of life. Physical activity was assessed with the three-item PARS-3 scale, which combines usual exercise intensity, duration and frequency. Quality of life was measured with the KIDSCREEN-10 questionnaire, referring to the previous week.
In the statistical model, higher physical activity was associated with:
- More cognitive reappraisal, with a standardized path coefficient of 0.48.
- Better stress self-management, with a coefficient of 0.27.
- Higher health-related quality of life through the coping measures.
The links between activity and reappraisal, activity and stress self-management, reappraisal and stress self-management, reappraisal and quality of life, and stress self-management and quality of life were all statistically significant at p < 0.001.
The combined indirect association between physical activity and quality of life through the coping measures was 0.30, with a 95% confidence interval of 0.23 to 0.37. This was a standardized association—not a 30% improvement in quality of life.
How coping fit into the model
The researchers reported three possible indirect routes between activity and quality of life: through cognitive reappraisal, through stress self-management, and through reappraisal followed by stress self-management.
Approximate route estimates were 0.15 through reappraisal, 0.10 through stress self-management and 0.05 through both factors in sequence. The source notes that these figures were calculated arithmetically from the reported coefficients rather than separately reported by the researchers.
The model accounted for 33% of the variation in quality of life, 28% of the variation in stress self-management and 26% of the variation in cognitive reappraisal. It adjusted for gender, grade, academic stress, sleep and sports-club participation.
Some findings did not follow the overall pattern. Higher academic stress was associated with slightly less cognitive reappraisal, with a coefficient of −0.09. Students in sports clubs, teams or extra training reported slightly worse stress self-management, also with a coefficient of −0.09, even though overall activity was associated with better stress-management habits.
Why the results need caution
The classes were recruited by convenience, with teachers referring additional classes in the same schools. The sample therefore came from only two schools in one province and may not represent middle school students more broadly.
All measures were self-reported on the same questionnaire. That approach can make relationships between measures appear stronger. The source describes a one-factor check suggesting that common-method bias was not severe, but also notes that this is a weak safeguard.
The study did not collect socioeconomic information. Other factors—including family income, fitness, screen time, existing depression or anxiety, and personality traits—could have influenced activity, coping and quality-of-life scores together.
It is also possible that students who already feel better and cope more effectively have more energy or motivation to be active. Because the survey measured everything at one time, it cannot determine whether activity came first or whether another factor helped explain the pattern.
What the findings add
The results are consistent with earlier evidence summarized in the source, although that evidence also has limitations. A 2017 review included mostly observational studies. A 2024 analysis of 17 experimental studies found small pooled effects of exercise interventions on health-related quality of life and psychological wellbeing.
A 2023 analysis of 21 studies involving 2,441 children and teenagers found that physical-activity programs were associated with fewer depressive symptoms than control conditions. The reported benefit was larger among participants older than 13 and among those with diagnosed mental illness or depression.
Taken together, the evidence supports continued interest in how movement, emotional coping and wellbeing may be connected during adolescence. This survey, however, is best understood as evidence of an association and a possible pathway—not proof that increasing activity alone will improve a teenager’s quality of life.
