First pull out the rope to a suitable length, wind it into a circle, then pass it through the circle and tighten it.

The new year is here, has your waistline increased again? Many men tie their belts tighter in order to look straighter. A new Korean study found that wearing belts that are too tight not only affects digestive health but can also easily lead to back and knee soreness. Too tight a belt increases abdominal pressure. Researchers at Inje University in South Korea studied 12 healthy men.

A study was conducted on the association between belts and knee disease. The researchers asked all participants to wear a belt with a tightness corresponding to a 10% reduction in waist circumference. The results showed that when the participants stood up, the tight belt changed the way their upper abdominal muscles moved. The researchers analyzed that.

A belt that is too tight will increase abdominal pressure, make the spine stiffer, and increase the risk of disease. Not only that, a belt that is too tight will also affect the center of gravity of the body and the normal position and direction of the pelvis, greatly affecting the gait and increasing the pressure on the knee joints. This study focused on men, and the impact of tighter belts on women and obese people needs further study.

Abdominal obesity increases the burden on the knee joints. In the past, the first cause of knee arthritis was strain caused by overwork in youth. However, in recent years, obesity has become one of the most important factors in the disease. This It is related to the increasing number of obese people, especially those with abdominal obesity. Due to weak abdominal muscles, these people's abdomen bulges forward and the body's center of gravity shifts forward. In order to adapt to this change, lumbar protrusion increases.

The muscles in the lower back are overstretched and the burden on the knee articular surface is increased, which accelerates the wear and aging of the joints and causes arthritis. Under normal circumstances, articular cartilage covers the bone surface like a pad, which can cushion the shock pressure during joint movement, reduce motion friction, and allow the joints to move freely. But when the joints are overburdened or worn excessively, the cartilage surface can become damaged.

In addition, obese patients have abnormal hormone levels and abnormal hormone metabolism, which can also lead to cartilage metabolic dysfunction and induce osteoarthritis. More important than weight is waist-to-hip ratio. So, how to determine whether you are obese in the abdomen? An easy way to calculate this is to measure your waist and hip measurements while standing, and divide your waist measurement by your hip measurement.

Get the waist-to-hip ratio. Hip circumference is based on the largest part of the buttocks, and waist circumference is measured through the belly button. The upper limit of waist-to-hip ratio for men is 0.85~09, and for women it is 0.75~08. If it exceeds this range, it means abdominal obesity. Typically, a larger waist-to-hip ratio indicates more fat in the internal organs. A waist-to-hip ratio that exceeds the standard indicates that fat may be concentrated in the internal organs. Abdominal obesity is very dangerous and can easily lead to various diseases, including cardiovascular and cerebrovascular diseases, diabetes, etc.
