1. Security
In terms of safety, the only thing you need to pay attention to when using a treadmill to run indoors is the balance of the person. Some people may feel dizzy after running off the treadmill. In addition, since the running belt width of treadmills today is roughly 40CM, 45CM and 47CM wide, even with a 47CM wide running belt, people have to pay great attention to the balance of their body when running. If your feet are not careful Stepping outside the running belt may cause a fall due to an unstable center of gravity. For outdoor running, most people seldom find a stadium to run, generally running back and forth along the road, and there are many people on the road, and there may be safety accidents. In addition, a large amount of oxygen needs to be inhaled when running, and the exhaust gas emitted by an outdoor car is very harmful to the human body after being inhaled.
2. Weather
Weather is a factor that determines whether or not you can run outdoors. For example, foggy, rainy, and snowy days are not suitable for outdoor running, and there is no such limitation with a treadmill. The best way is to run outdoors when the weather is good, and run indoors on a treadmill when the weather is bad.
Three, running mood
Many people like to wear earplugs to listen to MP3 when running outdoors, and to listen to music while running. Although this can maintain a happy mood, I think it is not very comfortable to run with headphones after sweating. The treadmill is different. Nowadays, most treadmills come with the function of playing MP3, and have audio, so that exercisers can run while listening to music without wearing earphones. Of course, this is just a small advantage of treadmill running compared to outdoor running.
Fourth, exercise effect
Because of the complex terrain, outdoor running can exercise all parts of the person, while the treadmill can only run in a straight line. In this regard, the former is better than the latter. In the control of running speed, people are controlled by themselves outdoors, because people cannot clearly know the bearing capacity of their various organs, so it may lead to overtraining and injury to the body. This can be well controlled on a treadmill. Most treadmills have a function to detect heart rate. Exercisers can judge their body load based on scientific data, thereby increasing or decreasing the running speed and time.
