#每天慢跑4公里这件事, how long can you last#30 minutes of running to cover a distance of 4 kilometers, this speed is not fast, but it also varies from person to person!
If you want to know if running 4 kilometers in 30 minutes is slow? So, let me tell you the answer, let's take a look!
First of all, the speed of running is about pace. We need to understand the concept of pace and how it is calculated. Pace is the average time taken per kilometer of running, usually expressed in minutes per kilometer. Therefore, a pace of 4 km in 30 minutes is an average of 7.5 minutes per km.
According to the general concept of running speed, a pace of 7.5 minutes/km falls under the category of jogging. For exercisers under the age of 40, this running speed is indeed very slow, and it belongs to low-to-medium intensity aerobic exercise, and the exercise effect is average.
However, for middle-aged and elderly exercisers over 50 years old, this kind of jogging speed is just in line with physiological age, and it belongs to a moderate-intensity aerobic exercise state, which is safe for the body and has a good exercise effect.
However, for beginner exercisers, ordinary girls and people with poor physical fitness, this pace running is already high, and it may be 4 kilometers away, and it will not be able to run for 30 minutes.
Although jogging is an easy and comfortable way to run, suitable for middle-aged and elderly people to exercise, and also suitable for novices to practice, it should also be carried out at a moderate running speed, too slow will reduce the effect of exercise.
Therefore, exercise should gradually adapt and increase the running speed to improve cardiorespiratory fitness and endurance. Of course, everyone's physical condition and exercise goals are different, so choosing a pace that suits you is the most important thing.
In short, running 4 km in 30 minutes is slower, and it belongs to the category of jogging, which is suitable for beginners and people with poor physical condition.
