1, leggings running will seriously harm your health, and the method has long been eliminated at home and abroad. The main injuries are obstructing blood circulation, crushing bones and hurting joints. When running, the blood flow of the body is very fast, which will bring nutrition to the main sports parts, discharge the "waste" and play a role in transportation.

Leggings will "hinder" the transportation of blood and limit the flow of blood to the legs. In this way, in the process of exercise, the body's metabolic capacity drops in an all-round way, and the "waste" produced by leg exercise cannot be discharged, which will make the exercise level decline more and more. Not to mention the exercise effect.

2. Running itself is a serious injury to knees and ankles, and load-bearing leggings aggravate this injury, giving greater friction pressure to ligaments of knees and ankles and improving the injury value. At the same time, because the leggings are tightly tied to the calf, the resistance pressure of the calf bone will increase every time the leg is lifted, and the calf bone is not as thick as the thigh bone, which will cause damage to the bone after a long time.

3. At present, this exercise method has been completely cancelled in routine training at home and abroad. For professional athletes who do a lot of exercise every day, the injury is unimaginable and will seriously shorten their sports life.

The correct way to improve running is to train the explosive power of thighs and calves in sprint, and high-intensity strength training has better effect and no harm. For long-distance running, it mainly depends on muscle endurance and cardiopulmonary function. Weight-bearing training can't improve endurance at all, only by running more.

Sun, an associate professor of physical education and training at Beijing Sport University, said that tying sandbags to increase physical load can really improve exercise efficiency and increase the energy consumed in the same time. Professional athletes often use this method when losing weight.

If ordinary bodybuilders try to carry weight during exercise, Sun suggests adjusting the weight according to their own situation first, so as to achieve gradual progress; Secondly, if the load is placed on the arm or leg, pay attention to the weight symmetry on both sides; In addition, it is to prevent the edge of the sandbag from grinding the skin during movement; In addition, because the material outside the sandbag is generally nylon cloth, the air permeability is poor and it is not suitable for long-term binding.

Exercise should also have a sense of joint protection to avoid excessive activities such as frequent going up and down stairs and climbing mountains. Middle-aged people should pay attention to the fact that squatting will increase the pressure on the knee joint, protect the joints that have been affected, reduce the joint load, lose weight, and avoid long-term weight bearing and bad posture.

Excessive walking will increase the joint burden and aggravate the original minor injury; Excessive walking or going up and down the slope will also increase the pressure on the patellar joint, and the patellar cartilage is prone to problems after long-term friction. Persistent excessive exercise will cause joint pain, which will seriously cause arthritis, plantar fasciitis, achilles tendonitis, neurilemmoma periostitis, hip synovitis and so on.
