A study from McMaster University suggests that mental health has become both a barrier to and a motivator for physical activity.
Surveying over 1600 subjects, the researchers sought to understand the ways mental health, physical activity and sedentary behaviour have changed throughout the course of the pandemic and why. Their findings show that people want to be active to improve their mental health but find exercise difficult because of stress and anxiety. Previous research indicates that physical activity can contribute to the treatment of depression, while sedentary behaviour has a strong negative impact.
“Maintaining a regular exercise program is difficult at the best of times and the conditions surrounding the COVID-19 pandemic may be making it even more difficult,” said lead author Jennifer Heisz, associate professor at the Department of Kinesiology, McMaster University.
“Even though exercise comes with the promise of reducing anxiety, many respondents felt too anxious to exercise. Likewise, although exercise reduces depression, respondents who were more depressed were less motivated to get active, and lack of motivation is a symptom of depression,” she said.
The survey respondents reported higher psychological stress and moderate levels of anxiety and depression due to the pandemic. Their weekly aerobic activity reduced about 20 minutes, strength training down roughly 30 minutes, and sedentary time per day was up about 30 minutes per day compared to six months prior to the pandemic. Physical activity may have exerted a protective effect, as those with the greatest drops in physical activity had the worst mental health outcomes, while those who kept their physical activity levels the same level fared better in terms of mental health.
Notably, economic disparities played a role, the researchers found, especially among younger adults.
“Just like other aspects of the pandemic, some demographics are hit harder than others and here it is people with lower income who are struggling to meet their physical activity goals,” said co-lead author Maryam Marashi, a graduate student in the Department of Kinesiology. “It is plausible that younger adults who typically work longer hours and earn less are lacking both time and space which is taking a toll.”
After the researchers analysed the data, the researchers produced a guideline to help people become more physically active:
- Adopt a mindset: Some exercise is better than none.
- Lower exercise intensity if feeling anxious.
- Move a little every day.
- Break up sedentary time with standing or movement breaks.
- Plan your workouts like appointments by blocking off the time in your calendar.
“Our results point to the need for additional psychological supports to help people maintain their physical activity levels during stressful times in order to minimize the burden of the pandemic and prevent the development of a mental health crisis,” concluded Heisz.
