I haven t run for a long time, and I feel that my physical fitness has dropped a little, why is it d

Because the body can't adapt for a while. If you stop running, your physical fitness will decrease, and you won't be able to keep up when you start running.

Because if you don't run for a long time, all the nerves of the human body are in a lazy state, so if you don't run for a long time, your physical fitness will decline, and it will be much more difficult to run again.

It's okay, look at how long you ran before and how long you haven't run again, after all, running is a little bit, you haven't run for a long time, don't be too high for yourself, increase the running time and pace a little bit, and the total number of kilometers should be less first, and slowly increase so that it is better for yourself.

Because at this time, the body can no longer adapt to the rhythm of running, so it will be like this.

The first main reason is that when you run, your body has no strength and no explosive power, that is, the body does not have this sense of muscle, that is, you should train your muscles. The second point may be that your body's metabolism is out of balance, so you don't have the energy, so you can't run long.

It may be that your physical fitness is not good, and it may also be that your basal metabolic ability has decreased, so your physical fitness is not good.

It may be because of the wrong running technique, which consumes a lot of physical strength and accelerates the fatigue of the muscles.

Because the excitability and flexibility of all organs in the body decline very quickly.

It's like a machine that doesn't use it for a long time and will rust quickly.

Because the human body needs to have a process of readaptation. When we don't exercise for a long time, our body functions will decline dramatically.

It is definitely difficult not to run for a long time, because your body has adapted to not doing intensity training, and naturally you still like to sit and lie down and not exercise. So running again still requires a process of adaptation.

Because at this time, the body has become lazy and is not suitable for high-intensity exercise.

The main reason for this is that the body is not used to running for a long time, so the body will have a stress response when running, and it will be very difficult and uncomfortable.

Because of not running for a long time, the body has become accustomed to the current laziness situation, and when you run again, it is the same as at the beginning, you need to take it step by step, and the muscles will slowly adapt.

If you don't exercise for a long time, the decline in muscle strength and cardiorespiratory endurance will be obvious, and the overall physical fitness will also decrease. So when you run, you get tired.
