For a 75-year-old resident surnamed Han, a comprehensive prescription of exercise, medication and diet has reduced the symptoms of her high blood pressure.

"Before, when I exercised in the park, if I pushed too hard, my knees would hurt," she said. "Now, I follow a professional doctor's guidance right in my neighborhood, and all my health indicators are stable."

Partnering with the city's education commission, Tianjin Hospital is also bringing "sports for health" programs into schools to address sedentary posture and obesity.

"Exercise prescriptions for children must be particularly scientific and effective without risking overtraining or injury," Xu said.

For the elderly, standardized muscle-strength and coordination testing has become part of community health services to reduce the high incidence of age-related fractures.

"Older people of different ages and physical conditions require individualized assessments of what exercises they can and cannot do," Xu said.

Tianjin has integrated fall prevention guidance for the elderly into community health services, supplemented by recommendations for home modifications to make living environments safer for seniors, thereby protecting their quality of life from multiple angles.

"We measure balance, strength and flexibility, and then prescribe an exercise plan," Xu said.
