The purpose of running for the general public is mostly to improve endurance, that is, to conduct aerobic activities to enhance cardiopulmonary function.
So is it better to run on the playground or on the treadmill?
Many people who have tried both said that they feel more relaxed when running on the treadmill than when running on the playground or in the wild, and this feeling is normal.
Studies have shown that the calories consumed by a treadmill are about 95% of the calories consumed by outdoor running in the same period of time.
The reasons may include
① Outdoor running requires overcoming a certain amount of wind resistance;
② The "track effect" of the treadmill reduces many additional actions when people run, such as pedaling, thigh swinging, etc.;
③ When running on a treadmill, people only need to overcome the effect of gravity, and relatively less friction.
So is the treadmill bad?
Of course not!
Most treadmills in modern gyms are composed of shock-absorbing tracks, which have less impact on the knee joints and can effectively protect the knees.
Indoor exercise avoids some interference factors of outdoor exercise, such as bad weather and safety issues, but in comparison, the air circulation in the gym is not as good as outdoors, so it is not recommended to stay for a long time.
In addition, the treadmill can control the fitness person to exercise at a uniform speed, and can display the calories consumed, immediate heart rate, etc., so that the fitness person can control the intensity and time of exercise independently.
Therefore, in summary, outdoor running and treadmill running have their own advantages and disadvantages in practical application, and fitness people can make choices according to their actual situation.
