Moderate Exercise Linked to Lower Risk of Sarcopenic Obesity in Seniors: Study - Video

Older adults who remain physically active have a significantly lower risk of developing sarcopenic obesity, a serious condition characterized by excess body fat combined with reduced muscle strength.

According to new research from Örebro University, even activity levels below current exercise recommendations can offer meaningful protection. The findings were published in the Journal of Cachexia, Sarcopenia and Muscle.

Sarcopenic obesity is particularly concerning in people over 65 because it increases the likelihood of chronic diseases, frailty, mobility limitations, and loss of independence.

The study included more than 860 men and women aged 65–79 from four European countries. Unlike many previous studies that relied on self-reported activity, this research used motion sensors to objectively measure physical activity levels, providing more reliable data.

The results showed a strong association between physical activity and lower risk of sarcopenic obesity. Older adults who engaged in moderate exercise—such as brisk walking for approximately 75 minutes per week—had up to a 50% lower risk compared with those who were completely inactive. Participants with the highest activity levels demonstrated up to an 80% reduction in risk.

Importantly, the protective effects were not limited to structured workouts. Even low-intensity activities, including standing, slow walking, and general movement throughout the day, were associated with health benefits, particularly for individuals unable to perform vigorous exercise.

The findings remained significant after adjusting for factors such as diet, inflammation levels, and muscle-weakening diseases.

The study underscores that reducing sedentary time and incorporating regular movement into daily routines can play a crucial role in preserving muscle strength and metabolic health in older age.
