Being in good shape can protect against health problems related to stress at work, a new study finds. Sport scientists in Switzerland and Sweden discovered a high-fitness level appears to protect individuals from the effects of work-related stress.
It is a well-known fact that fitness and well-being go hand in hand. But researchers now find that being in good shape also protects against the health problems that arise when we feel particularly stressed at work. As such, experts recommend to stay physically active, especially during periods of high stress.
It also raises the likelihood of cardiovascular risk factors such as high blood pressure and an unfavorable blood lipid profile. Conversely, a high fitness level is associated with fewer depressive symptoms and fewer cardiovascular risk factors.
As published in the journal Medicine and Science in Sports and Exercise, researchers discovered a high fitness level offers particularly effective protection for professionals who experience a high degree of stress in the workplace.
Researchers recorded the fitness levels of almost 200 Swedish employees — 51 percent men, mean age 39 years — using a so-called bicycle ergometer test. In addition, they measured various known cardiovascular risk factors such as blood pressure, body mass index, cholesterol, triglycerides, and glycated hemoglobin.
The participants were then asked to provide information on their current perception of stress.
As expected, the study conducted by the University of Basel, the Institute of Stress Medicine, and Sahlgrenska University Hospital in Gothenburg, illustrates that stressed individuals exhibit higher values of most cardiovascular risk factors.
Furthermore, it was confirmed that cardiovascular fitness is linked to virtually all risk factors, with the risk factors being less high in people who are physically fit.
Researchers demonstrated for the first time that the relationship between the subjective perception of stress and cardiovascular risk factors is moderated by fitness. In other words, among the stressed employees, there were particularly large differences between individuals with a high, medium, and low fitness level.
For example, when stress levels were high, the LDL cholesterol values exceeded the clinically relevant limit in employees with a low fitness level — but not in those with a high fitness level. By contrast, where the exposure to stress was low, far smaller differences were observed between fitness levels.
“Above all, these findings are significant because it is precisely when people are stressed that they tend to engage in physical activity less often,” said Professor Markus Gerber of the University of Basel.
Furthermore, he said the study has direct implications for the therapy and treatment of stress-related disorders. To promote a physically active lifestyle, a high priority should be attached to the systematic measurement of cardiorespiratory fitness and the provision of theoretically sound and evidence-based physical activity counseling.
