However, when running in the same place, the main action is to run upward against gravity without lateral displacement. Therefore, the main training is only iliopsoas muscle and quadriceps muscle in front of thigh, which can not effectively practice buttocks, and the muscle groups trained are less than those run outdoors.
2. Different fat-reducing effects: outdoor running has a better fat-burning effect than in-situ running, but in terms of fat-reducing effect, in-situ running is not as good as outdoor running.
The biggest difference between outdoor running and in-situ running is wind resistance and friction. It takes more power to overcome resistance and do work. If it is cross-country running, it is also necessary to avoid obstacles and altitude rise and fall, which requires higher physical strength.
3, the advantages are different: the advantage of running in situ is simple and easy, not limited by the venue, even in rainy days. Although outdoor running has a better effect of reducing fat, it is more free and changeable, and it is easy to get hurt because of the influence of geographical environment, such as rugged terrain.
Running in the same place is boring, but the scenery is better when running outdoors, and people will be in a better mood when running. In addition, if there is an increasing purpose, then running in situ will be better than running outdoors. So both have advantages and disadvantages.
