What are the disadvantages of outdoor sports for the elderly at sub-zero temperature?

The temperature is very low in the morning and evening, and blood pressure will increase with the decrease of temperature. Old people who go out to exercise at low temperature are more likely to induce cardiovascular and cerebrovascular diseases, and cold may also induce bronchial asthma.

It is best not to do outdoor high-intensity exercise in foggy days, which has an impact on the respiratory system and cardiovascular system;

However, exercise in windy days can easily cause cold, chills and chapped skin.

In addition to the outbreak, many elderly people also like to constantly leg press on the equipment and pull their necks.

Sports medicine experts in the Third Hospital of Beijing Medical University reminded that the elderly should use some head and neck traction devices "small and slow", that is, the traction weight should be small at first and gradually adjusted according to the adaptability of the elderly. At the same time, the traction angle is also particular, not vertical pull. The harder the better, otherwise it will easily cause serious damage to cervical spine, spinal cord, nerves and blood vessels;

There are also some elderly people who like to keep lifting their legs and pressing the bed on the equipment, but long-term excessive traction will make the joint range of motion too large, and if the muscle strength around the joint is insufficient, it may lead to injury.

"The physical quality of the elderly should be improved in all aspects. When choosing a specific type of exercise, we should consider the individual's sports history and current physical fitness level. It is recommended to use low-intensity exercise with less time and more times. "

It should be specially reminded that for the elderly, excessive aerobic exercise is not good for osteoarthritis and osteoporosis, and should not obviously exceed the amount of exercise they can bear.
