According to the report, the participants in the study ran for 30 seconds and then rested for 30 seconds, so they exercised outdoors and on the treadmill for 15 minutes respectively. Researchers will measure the oxygen consumption and exercise intensity of participants after two types of running.
The research results were published in the Canadian journal Applied Physiology, Nutrition and Metabolism.
The results show that when running on the treadmill, the runner's oxygen consumption is greatly reduced, which shows that it is more energy-saving.
The author of the research paper wrote: "When exercising on the treadmill, the running speed should be accelerated by 65,438+05% to produce the same physiological response as external exercise."
According to the report, although this study does not speculate why running on the treadmill seems to be more energy-saving, previous studies have pointed out that the running belt moving on the treadmill will push the runners forward, thus making them run faster.
Moreover, indoor exercise also means that exercisers don't have to deal with steep slopes or wind resistance.
Michael silverman, head of the Department of Rehabilitation at Northwest Chester Hospital in new york, said: "Outside, the ground conditions are constantly changing, and it is necessary to fight against strong winds and make an emergency stop, which will lead to burning more heat."
Outdoor running or treadmill
Outdoor running
Advantages:
Outdoor running is the most primitive way of human exercise. Just put on your running shoes and walk out of the house, and you can start running. Outdoor running can run to different places, giving you a sense of freshness and satisfaction, and you can also feel how long you have been running, especially the feeling of getting closer and closer to the finish line, which can continuously generate motivation.
Disadvantages:
When the temperature is too high or too low, encounter bad weather such as rain and snow, lack of outdoor light at night, and bad outdoor security, outdoor running will be restricted. Running outdoors is prone to falls, sprains and even more serious injuries.
Treadmill
Treadmill running is equipped with cushion and other damping devices, which can reduce the impact on the body compared with ordinary hard ground, and is especially suitable for people who are overweight and have knee joint injuries.
It is not easy to cheat when exercising on the treadmill, and the requirements for exercisers are the same, which is conducive to tempering the will.
The running belt is driven by a motor, and the running stride is different from the natural state of outdoor running. After running on the treadmill for a long time, it is easy for exercisers to form an upright posture and a bouncing posture without wind resistance.
If you are used to running on the treadmill for a long time, after running outdoors, your muscles, tendons and ligaments may not adapt to various terrains, such as sharp bends, potholes and steps. And easy to get hurt.
On the treadmill, you can't see the changing scenery along the way, only the dull display panel and fixed digital jumps, which makes the exercise very monotonous and boring.
