The jogging boom has subsided because jogging caused a burden on the joints of the hips, knees and ankles because of the Impact on each part of the body from running as an exercise on the land. Recently, instead of jogging, walking has become popular since the load on the body is relatively less.
Walking on land is one of the most fundamental actions in daily life.
It is also relatively easy for the body compared with jogging, but for people who it is difficult to exercise on the land due to obesity or those who have problems with their joints, it is still not an easy exercise.
On the other hand, aqua training can freely adjust the load suited to you by using the advantage of lighter weight with the buoyancy of water.
So, it is useful for health improvement regardless of physical characteristics, presence or absence of injury, athletic ability, age of users.
1. Water pressure is about 1,300 kg on a standard body shaped person. The deeper the water depth, the greater the water pressure, the circulation of blood returning from the lower body to the heart is improved. In addition, the water pressure provides a moderate load to the chest and helps train deep breathing. It is more effective for improving cardiopulmonary function.
Move your hands in water. You should feel the water trying to push your hands back. That is resistance. The wonder of this resistance of water is that the faster movement is, the greater the resistance becomes, and if you move it slowly it will become less. In other words, it means that you can freely control the load on your body by your own will. Aqua exercise is a revolutionary exercise that can maintain exercise with a load and pace suitable for each person.
When Jumping on land, there will be 2 to 3 times more weight on your knees when landing. Compared to this, the weight decreases to about 1/10 of the weight on land (if up to the neck in water) when underwater, so there is not much shock when jumping. That is why Aqua exercise is safe and effective as rehabilitation. Merely when floating on water, your muscles relax and blood circulation improves, so you can achieve a high relaxation effect and expect stress relief.
The human body is quickly deprived of body temperature in the water. It is because water tends to transmit heat more than air. However, our body tries to raise and maintain body temperature by raising energy production in the body. This is why aqua exercise is an exercise has a high shape-up effect. Also, since water lowers the body temperature that has been increased by exercise, it will be possible to exercise for a longer period.

Although the place is restricted as a "pool", basically it is not affected by weather and not necessary to have a partner to exercise together with (though a long lasting trick is making friends). You can enjoy it at your own pace. There is no need to put your face underwater, so people who cannot swim have less fear of water is another advantage.
As the buoyancy works in the water, your weight is less and you become almost weightless, you can obtain the effect of exercise more safely and more efficiently than the movement on land.
As the resistance of water, the resistance increases as the speed of operation increases, and the resistance decreases as the speed of operation decreases. Furthermore, you can increase or decrease the resistance of water by using hands and feet. Like these, you can set the load depending on the level of the individual ability by using underwater effectively.
By performing aerobic exercise with a slow exercise intensity, it is not only expected to reduce obese for burning body fat, but helps improve lifestyle-related diseases such as diabetes, high blood pressure and hyperlipidemia etc.
By adding water pressure, deep breathing is forged, the pumping action of the heart becomes stronger and the heart rate increases slightly. Furthermore, as the blood circulation improves, the cold regulating function recovers. It helps improve congestion, swollen limbs, shoulder stiffness, back pain, etc.
Even those who are concerned about joints such as hips, knees and ankles can exercise effortlessly; it is effective for the prevention of osteoporosis. And also, it can adjust hormone balance and overcome menopausal disorder in women.
