Sports little knowledge, don't miss it if you don't look!
1. After a long time of fitness exercise, do not drink water directly
After a long time of fitness exercise, a large amount of salt is excreted from the body through a large amount of sweat. Drinking too much water will reduce the osmotic pressure of the blood, affecting the normal physiological function of the human body. During exercise, the heart rate and breathing frequency need to be increased to increase the blood flow and oxygen to meet the exercise needs. Excessive drinking of water will cause the stomach to swell and fill, hindering the movement of the diaphragm, affecting breathing; increased blood circulation flow will increase the burden on the heart, which is not conducive to exercise and will harm the heart.
2. Do not exercise immediately after eating
After eating, a large amount of blood needs to flow to the stomach and intestines to help with food digestion and nutrient absorption. If you participate in exercise at this time, it will cause blood flow to the limbs, hindering the digestion of the stomach and intestines. For frail people, blood pressure may also drop after eating, making outdoor activities prone to falls. Long-term post-meal exercise is easy to get ileitis. Do not drink alcohol before swimming or other sports.
3. Exercising in an inappropriate place will bring harm
Because the basic function of exercise is to take in a large amount of fresh oxygen from the outside through breathing to meet the health needs, it is necessary to choose a good place before exercising, such as flat and open parks, riverbanks, and sports fields with fresh air.
4. Do not exercise when you are in a bad mood
Exercise is not only physical exercise but also mental exercise. When you are angry or sad, do not go to the sports field to vent. Sports medicine experts explain that emotions directly affect the physiological functions of the body, and emotional changes originate from the deep parts of the brain and spread throughout the body, leaving traces on the heart and other organs, which will affect the health of the human body's functions.
5. Choose the best exercise volume
There are many ways to choose the best exercise volume: for example, index assessment method, heart rate assessment method, Cooper assessment method, Fix assessment method, fatigue assessment method, simple assessment method, stage assessment method. Since every person's actual situation is different, the quiet heart rate difference is 15-30%, or even more, so the best exercise volume should be determined according to one's age, gender, occupation, physical strength, health level, sports foundation, living environment, and purpose task.
6. Massage properly after exercise
Recovery refers to the series of relaxation exercises and post-exercise massage adopted after physical exercise, its purpose is to eliminate fatigue, restore physical fitness, and improve the effect of exercise.
