What causes calf pain after brisk walking?

Nowadays, people all know that exercise is a good way to stay healthy, so no matter what time it is, you can see people doing exercise outdoors. In addition to running, older grandmas and grandpa may walk, but they just walk faster than usual, which can achieve the effect of exercising the body. So, what is the cause of calf pain after brisk walking?

1. Generally, muscle soreness will occur 12 to 48 hours after exercise. If you are not used to exercise and this is your first training session, the soreness will be more obvious. The scientific name for this type of soreness is: Delayed onset muscle soreness. It is caused by the accumulation of lactic acid and the breakdown of muscle microstructure. Lactic acid accumulation is caused by the presence of lactic acid in the metabolic products of glycolysis during strength training; the damage to the muscle microstructure will heal during the recovery period after training, and the healed muscles will become thicker than the original muscle fibers. This is called the super recovery principle, which is the driving force of muscle growth.

2. Since the muscle microstructure is damaged after training, hot baths or hot compresses will accelerate the blood circulation of the injured muscles, thereby aggravating the damage to the muscle microstructure. If you take a hot bath after heavy weight training, you will definitely feel more sore the next day than if you take a cold bath. At the same time, hot baths accelerate the metabolism of muscle tissue. The training before the hot bath has already consumed a large amount of muscle glycogen in the muscles. Using a hot bath to continue to accelerate metabolism will increase fatigue and even lower blood sugar. Taking a hot bath after training will increase fatigue and make people feel drowsy, while taking a cold or warm bath will significantly reduce fatigue.

Therefore, it is best to take a cool bath after training, or apply cold compresses around the active muscles of the movement. 1. Cold compress in the early stage: Use ice packs to cool the target muscles immediately after heavy weight training. Generally, the cold compress lasts for 10 to 15 minutes. Place clothing or towels between the ice pack and the skin to prevent frostbite. Or a cold shower. The national weightlifting team has a special ice and snow room in the General Administration of Sports' Heavy Duty Arena. After heavy weight training, the national team players go directly into the ice and snow room with a temperature set at 0 degrees in their underwear in order to speed up their recovery.
