According to a report from the Institute of Sport Science, 90 percent of body muscle works while Nordic walking. It consumes 20 to 46 percent more calorie than regular walking with the same speed, time and length.

In a survey of more than 400 Chinese Nordic walkers in 2012, 70 percent said their knee pain has been eased after they adopted the exercise; 85 percent have less backache; 65 percent lost weight; 80 percent have lower level of blood fat.

The China Sports Association for Elderly People has been promoting Nordic walking since 2005. The Chinese Medical Doctor Association also recommends Nordic walking as one of the best ways to prevent cardiovascular diseases.

But the promotion does not always go well, said Xiao Gang. The sport began in Europe as off-season training of skiers in the Europe.

Since most Chinese people have no experience of skiing, walking with poles seems weird and embarrassed. It is also mostly adopted by elderly people, and Xiao said it would be helpful if the younger generations participate.

"But I believe it is getting more popular, as with something as simple as a pair of poles, people can benefit from the most regular physical activity," Xiao said. "The increasing number of walkers indicates the rising demand for healthy lifestyle in China, in the world's second-largest economy."
