Swimming can not only enjoy pleasant coolness, but also has a very "real" reason-research has confirmed that swimming is the most effective exercise for longevity.
The British "International Journal of Water Sports Research and Education" pointed out that swimming can enhance cardiopulmonary function, increase bone density, and is especially beneficial for people to develop good walking posture and reduce joint pain. Yuan Peng, a fitness coach, concluded: Such a healthy and safe exercise can be a lifelong fitness program.
Running in water doesn’t hurt your knees.
In a waist-deep pool, feeling the resistance of water, walking step by step is completely different from walking on land. At first, you can practice lower limb movement and swing arm in the water. When you are familiar with it, you can increase the range of movements, such as walking, walking backwards, running, and running in small steps.
Water fitness makes good use of the buoyancy of water to reduce the burden of gravity on the body. For example, when running on land, the knee joint has to bear an impact force equivalent to four times the weight, while running in water can not only avoid the injury to the knee joint, but also achieve the same exercise intensity. Overweight people can practice in the water to achieve the purpose of fitness.
Bicycle consumption in water is 20 times
Water spinning is a popular water fitness project in North America, which semi-submerges the stationary bicycle for the exerciser to pedal. Using the heat dissipation and fluidity of water, spinning in water is more interesting, and it has better effect on burning fat in legs and buttocks. Therefore, for people who want to lose weight in lower limbs, water spinning is a good fitness program choice in summer.
Moreover, because the thermal conductivity of water is more than 20 times that of air, even if it does not move in water, the human body will consume a lot of heat. Studies have shown that exercising in water for 20 minutes at the same intensity consumes the same amount of heat as exercising on land for more than one hour, which can quickly achieve fitness effects.
Shaping and moistening skin in water
If you want to shape, underwater body exercises are more interesting and effective. Including physical exercises such as equipment, yoga and aerobics in water, but these sports are not simply transplanted into water. For example, the instrument practice in water is mainly to take advantage of the resistance of water, and it can have a significant effect on shaping the chest, waist and buttocks with the help of empty water bottles, small buckets and balance rings. On the basis of traditional yoga, water yoga also adds camel style and horse running style, and makes full use of the resistance of water to protect the body from injury, thus reducing the possible physical injury and pain caused by traditional yoga practice.
When you exercise on land, you often forget abdominal breathing. However, when exercising in water, due to the pressure of water, the human body will be forced to change from chest breathing to abdominal breathing, which will strengthen the respiratory muscles and increase the vital capacity.
Moreover, when exercising in water, the temperature, pressure and resistance of water, as well as the flapping of water current and waves, can stimulate the skin, improve the blood circulation on the body surface, keep the skin moist and elastic, and delay aging, which is the first choice for women who love beauty.
Tips: The water temperature for body-building in water should not be too cold, and 29℃~30℃ is the best. The best exercise time is before meals or one hour after meals, 2~3 times a week for 30~45 minutes each time.
