1, prolong penis erection time.
In male breaststroke, leg muscles, abdominal muscles and pelvic floor muscles are all exercised by opening and closing the legs one by one. These muscles are only used in the same room, which can make men more relaxed, prolong penis erection time and improve sexual ability and self-confidence.
2. Improve lung capacity
When swimming, there is a certain pressure on the chest, coupled with the stimulation of cold water, the muscles are constantly contracting, making it difficult to breathe, forcing people to breathe hard, increasing the depth of breathing, thus improving vital capacity. In addition, swimming can promote the development of respiratory muscles, increase chest circumference and increase vital capacity.
3. Improve the ability of the muscle system
Swimming requires the participation of all muscles, which can improve the strength and coordination of many muscles, especially the upper limbs, shoulder straps and trunk. As long as men insist on swimming, they can improve muscle strength, speed and endurance, and increase joint flexibility.
4, accelerate skin blood circulation
Because of the stimulation of water temperature during swimming, skin and blood vessels participate in the regulation to ensure sufficient temperature. Skin blood vessels contract under the stimulation of cold water to prevent heat from spreading outward. At the same time, the body has stepped up the generation of heat, which makes the skin blood vessels dilate, improves the blood supply of the skin blood vessels and strengthens the blood circulation of the skin. In addition, when swimming, water can wash away the skin, fat glands and sweat glands, which is equivalent to a massage, which can promote the blood circulation of the whole body and make the skin smooth, delicate and elastic.
Step 5 lose weight
When swimming, the body is immersed in water, which has high resistance, good thermal conductivity and fast heat dissipation, and can consume more heat. Swimming can avoid waist and lower limb injuries and is suitable for obese people to lose weight. In addition, using the buoyancy of water to relax and stretch the whole body during swimming can make the body develop in a balanced and coordinated way and make the muscle lines smoother.
6, can enhance resistance
Swimming consumes a lot of energy. In order to quickly replenish the heat emitted by the body and meet the needs of cold and heat balance, the nervous system will react quickly, speed up metabolism and increase the body's adaptability to the outside world. At the same time, it can also improve endocrine function, increase pituitary gland volume, and improve resistance and immunity.
Matters needing attention in men's swimming
1, cleaning the body
Whether you are swimming in the water or coming out after swimming, you should wash your body with clear water. Because most of the water in the swimming pool contains disinfectants, cleaning the body can prevent these disinfectants from adhering to the body and hurting the skin.
2. You can't swim immediately before and after meals.
Swimming is an energy-consuming sport. Swimming on an empty stomach will cause dizziness and other symptoms because of excessive energy consumption. Swimming immediately after a meal will affect the digestive function, causing indigestion symptoms such as vomiting and abdominal pain.
Step 3 warm up before swimming
Men should do warm-up exercises before swimming in the water, so that their limbs can be integrated into the exercise, so that accidents will not occur because of discomfort when swimming in the water.
No swimming after strenuous exercise.
Don't think that strenuous exercise and swimming can burn fat quickly. Swimming immediately after strenuous exercise will increase the burden on the heart and make the body temperature drop rapidly. At this time, the invasion of cold can easily lead to diseases such as colds.
You can't eat immediately after swimming.
After swimming, many people will feel hungry and eat immediately, but this behavior is not desirable. Eating immediately after swimming will increase the burden of gastrointestinal and blood supply, and gastrointestinal digestion will lead to gastrointestinal diseases.
Selection of men's swimming trunks
1, fabric and color
① DuPont Lycra: It is an artificial elastic fiber with the best elasticity, which can be stretched to 4~6 times of the original length and has excellent extensibility. Suitable for blending with various fibers, which can enhance drape and wrinkle resistance. Dupont Lycra containing chlorine-resistant ingredients will make swimsuits have a longer service life than ordinary swimsuits.
② Nylon fabric: Although the texture is not as solid as that of lycra fabric, its elasticity and softness are equivalent to that of Lycra. At present, it is the most commonly used fabric for swimwear, which is suitable for middle-priced products.
③ Polyester fabric: it is an elastic fabric with unidirectional and bidirectional stretching. Because of its limited elasticity, it is mostly used in swimming trunks or women's swimming trunks, and is not suitable for conjoined models. Fabrics that can be partially spliced or applied with low unit price strategy.
Men's swimming trunks are mainly dark blue, black and other dark colors. But now light-colored swimming trunks are more and more favored by people, such as green, yellow and sky blue. But it will also lead to some controversy, especially wearing white swimming trunks. Many people dare not wear white swimming trunks. Bian Xiao thinks this is completely unnecessary, as long as the color is according to personal preference!
2. Height of waist
(1) high waist: usually designed as boxer trunks, they are almost eliminated now, so there are not many on the market.
② Normal waist circumference: You can use the angle triangle. There are many kinds of swimming trunks, which are usually the choice of the public, but I think they are more suitable for boxers.
3 low waist: most of them are triangular designs, because triangular swimming trunks are low waist designs, which look better than normal waist, and even boxers, but they will look very wide and ugly. Low-waisted swimming trunks are in fashion, and they are gradually catching up with those with normal waistlines, because triangles are becoming more and more popular.
④ Ultra-low waist: usually refers to the triangular swimming trunks with a little big thigh gap. This kind of swimming trunks is more suitable for open-minded people, because it can be described as sexy once, but it is not the mainstream of the public. After all, some people will say it's not normal.
3, girding method
Elastic band: There are many kinds of swimming trunks, but you must choose elastic when buying them. Because I bought it loosely, it can't be tight, and it is easy to drop. It's tight Uncomfortable But remind everyone that the elastic band is easy to age, lose elasticity and become loose after a long time in water.
Pant rope: the advantage is that the elasticity can be adjusted and it is not easy to age like an elastic band. However, this kind of swimming trunks is relatively rare and will be eliminated soon, and there may still be shortcomings.
(3) elastic bands and trousers ropes are: they can be said to be compatible and have the highest safety factor, so they have become the mainstream today.
