If you want to prevent disabilities later in life, here is the program of exercises you need

As people get older, the risks of reduced mobility and the difficulty of doing everyday tasks increase, but physical activity can help prevent disability, according to a new report.

Researchers at the Northwestern Feinberg School of Medicine recently conducted a study, published in the American Journal of Preventive Medicine, to examine the impact of physical activity on people with osteoarthritis, a type of arthritis appearing with aging.

They examined adults aged 49 to 83 years of the Osteoarthritis Initiative, a broad badessment of osteoarthritis of the knee. Participants experienced hip, knee, ankle or foot pain and were at increased risk of disability due to lower extremity symptoms such as pain or stiffness. The scientists followed the topics from 2008 to 2014.

At the start of the trial, the patients were not disabled, which meant that they were able to walk at a speed of 2 km / h and that they did not report any limitation of Daily activities such as getting dressed or walking around a room.

Scientists determined their activity levels using accelerometers, which measure speed, and surveyed participants on their health status every two years for four years.

After badyzing the results, they found that people who exercised vigorously for at least 56 minutes a week reduced their risk of impaired mobility compared to those who exercised less.

"Identifying an evidence-based goal of physical activity that supports these basic abilities can motivate inactive older adults to begin their journey toward a physically active lifestyle," said lead author Dorothy Dunlop. CNN. "If future work shows that a moderate activity relationship of one hour per week is favorably linked to other health outcomes, this threshold could be an intermediate goal in terms of health. Physical activity.

The authors noted that it was the first systemic study to determine the minimum time needed to prevent disability. However, they noted some limitations.

They admitted to having observed a specific group of patients with only lower extremity joint affections, as opposed to joint affections in general. They also stated that accelerometers were not able to record activities in the water and had perhaps underestimated cycling activities.

The team now hopes to continue their studies to encourage an active lifestyle for all.
