Swimming is a sport that many people like, and some elderly people often exercise by swimming. Appropriate swimming for the elderly has certain benefits for enhancing physical fitness. However, due to the decline of various functions of the elderly and the existence of some elderly diseases, special attention should be paid to swimming. It is recommended that elderly swimmers should pay attention to four things:
1. Prepare before swimming: First of all, the elderly should have a physical health check before swimming, and do a medical check before starting to swim or increase the intensity of exercise, which can prevent accidents during swimming. In addition, preparations should be made before entering the water, which can improve the excitability of the cerebral cortex and muscles, protect the heart, muscles and joints, and prepare all organs of the body before entering the water, which can avoid or reduce muscle cramps or strains appear.
2. Don’t swim immediately after a meal: The swimming time is best arranged one and a half hours after a meal. It is not advisable to go into the water immediately after a meal, because the digestive organs are digesting the food after a meal, and the gastrointestinal peristalsis of the elderly is slow. Swimming immediately after a meal will reduce the blood supply required by the digestive organs and the secretion of digestive juices, thereby affecting the digestive function and prone to abdominal pain.
3. The exercise intensity should not be too large when swimming: because the myocardial contractility of the elderly will be weakened, the elasticity of the blood vessel wall will also decrease, the lumen will be narrowed, and the blood resistance will increase, so the burden on the heart will also increase. The function has been weakened, and the vital capacity and ventilation volume will be reduced, which is prone to insufficient oxygen supply. At this time, such as fast swimming, the amount of oxygen consumption will increase, and the phenomenon of hypoxia and fainting is prone to occur, especially for the elderly with heart disease and high blood pressure. , swimming quickly can cause unexpected increases in pulse rate and blood pressure.
Fourth, other precautions: the elderly should avoid snorkeling practice, and pay attention not to go into the water immediately after strenuous exercise, and the amount of exercise should be gradually increased during swimming to allow the body to adapt slowly.
The above are four things to pay attention to when swimming for the elderly. Although swimming for the elderly can help to increase their physical fitness, if they do not pay attention to the relevant protection work when swimming, it is more likely to have some accidents. Therefore, it is recommended that the elderly People swimming must pay attention to the four points mentioned above to ensure their own safety.
