The new year is coming, has your waistline become bigger again? Many men usually fasten their belts in order to wear a tall and straight figure. A new study in South Korea found that too tight a belt not only affects the health of the digestive system, but also easily leads to back and knee pain. Too tight a belt will increase abdominal pressure. Researchers in inje university, Korea, took 12 healthy men as the research objects.
The correlation between belt and knee joint diseases was studied. The researchers required all participants to wear belts, and the tightness was reduced by 10%. It was found that when the participants got up, the tightened belt changed the activity pattern of their upper abdominal muscles. The researchers analyzed and pointed out.
Too tight a belt will increase abdominal pressure, make the spine more rigid and have a higher risk of illness. Not only that, too tight belt will also affect the normal position and direction of the body's center of gravity and pelvis, greatly affecting gait and increasing the pressure on the knee joint. This study takes men as the research object, and the influence of belt tightness on women and obese people needs further study.
Before abdominal obesity increased the burden on the knee joint, the first cause of knee arthritis was strain caused by overwork in youth, but in recent years obesity has risen to one of the most important factors, which is related to the increasing number of obese people, especially abdominal obesity. Because the abdominal muscles are weak, the abdomen is convex and the center of gravity moves forward. In order to adapt to this change, lumbar lordosis increases.
The lower back muscles are overstretched, and the burden on the knee joint surface is aggravated, which accelerates the wear and aging of the joint and causes arthritis. Under normal circumstances, articular cartilage covers the bone surface like a pad, which can cushion the vibration pressure during joint movement, reduce the friction during movement and make the joint move freely. However, when the joint is overburdened or excessively worn, the cartilage surface will be damaged.
In addition, abnormal hormone levels and hormone metabolism in obese patients can also lead to cartilage metabolic dysfunction and induce osteoarthritis. What is more important than weight is the waist-hip ratio. So, how to determine whether the abdomen is obese? There is a simple calculation method. Measure waist circumference and hip circumference when standing, and divide the waist circumference by hip circumference.
Get the waist-hip ratio. Hip circumference shall be subject to the maximum hip circumference, and waist circumference shall be measured through navel. The upper limit of waist-hip ratio is 0.85~09 for men and 0.75~08 for women. If it exceeds this range, it means abdominal obesity. Usually, the greater the waist-hip ratio, the fatter the internal organs. Waist-hip ratio exceeds the standard, indicating that fat may be concentrated in internal organs. Abdominal obesity is very dangerous and can easily lead to various diseases, including cardiovascular and cerebrovascular diseases and diabetes.
