I make use of resistance of the flowing water, and a running water pool is an apparatus enabling swimming and exercise, rehabilitation efficiently. For one of the characteristics, I can continue swimming like a treadmill for the running without turning at a constant place. I am called en:swimming machine (swimming machine) or counter-current (countercurrent) and the resistance (resistance)-type pool in English. There are usually many compact things formed from the arm of the general person, length of approximately 2 times that is in condition to have postponed a leg, a water tank of the width of approximately 1.5 times. I perform swimming or the exercise against the current which I can regulate made by the driving means such as a jet, a propeller or the paddle wheel. Such "running water pool" born in the 1970s raised a flow by an air jet of the pressure-style pump drive at first, but was not environment appropriate for the swimming because it was considerable turbulence. This was succeeded for propeller and paddle wheel type drive and, in the 1980s, became the smoother current. I can divide it into an air pressure type, 高容水量式 and three categories called the running water outbreak system for the existing pool mainly now.

Air pressure-style drive system (jet)
Summary
I am called a "swimming spa" type, and a thing using this system is a thing of the styles that did a "spa" function mainly rather than "a pool". In a single zonal normal "swimming spa," groups are put together space and spa (or a jacuzzi) space for the exercise so that the name suggests it. It is made of FRP (fiberglass), and plural air pressure-type pumps moving water are equipped with, and jets for the swimming are usually attached jets for the massage with the seat for the spa to another in the one side. In the case of a motor of 3HP (approximately 2.25kW), the space for the exercise enables, for example, a discharge of 13L/s (for 206 U.S. gallon /) [1]. Because it is a fabricated state and is already sold, it is apt to be thought that it is more convenient, but the main body is thin for mass production, and reinforcement work is necessary. In addition, because it is generated not the quantity by the speed and the water pressure of the current, stimulation is strong, and the running water is practical for a massage therapy tool, but the evaluation from a swimmer is low saying that turbulence is over qualitatively. On the contrary, the turbulence of the sea is thought to be by a person swimming in triathlete and the sea that this simulated experience done jet type helps durability improvement.
Career
In one of the models born earliest in the market, there is "Badujet" (バドュジェット) [2] which Speck Pumps company announced in 1973. This is a promotion system of the water attached to an existing pool. In the 1980s, "Monarch Spas" (モナークスパ) [business closing] developed the swimming spa type of 2 zones and was designed so that the pump for the pool and other equipment used it in the spa of another area. An advantage of 2 such zone systems is that temperature setting varying according to a use and the use of chemicals are possible. For example, the spa zone using bromine can keep the pool zone using chlorine to the low temperature that is appropriate for intense exercise for enough heat for relaxation and massage. In 1994, "HydroWorx" (hydroworks) [3] acquires the patent of the air pressure-type pool for the company's first treatment. I used an underwater treadmill with an air pressure-type jet for rehabilitation use. The horse that the Paul Hetrick doctor who was a founder was hurt saw the figure which underwent rehabilitation with a treadmill out of the duties water and hit [4]. I adopt the underwater monitoring system which projects the figure of the user on the monitor so that a therapist coordinates treatment in the later version in real time [5]. Many makers such as PowerPools (power pool) made in "swimming spa" and MAAX company [6] of the world imitate the product causing running water by such a jet-type system and sell it.

Summary
As for the thing using this system, there is driving means causing a current by a propeller and a paddle wheel mainly. A product made in FRP is made of metal, and there is mass production vs. build-to-order manufacturing. Because there is a difference by each maker, as for the quality and the capacity of the current formed by a device, it is necessary to choose the most suitable thing by purpose and how to use user.
Career
A new machine comes up in the 1980s. The system which woke up a smoother current was devised for the purpose of breaking off discomfort of the running water and turbulence with many air bubbles by the jet drive. The first, "SwimEx" which Stan Charren and the engineer of two of the Massachusetts Institute of Technology university graduate developed in 1984 is (Sui Mecs) [7] [8]. This machine which strong FRP bookbinding body and instrumentation are adjacent, and is installed produces a stable current to pool overall width by moving the quantity of water that there is not of the kind in others of 1,890L/s (for 30,000 U.S. gallon /) by a patent paddle wheel technology. It is done a lineup house use provided with a luxury feeling more if for main facilities aimed for by rehabilitation and therapy, and it is that I made all much of functionality, the durability, safety. By build-to-order manufacturing, it may be said all that it is the high-end model of this industry. In the latter half of the 1980s, [10] was developed (endless pool) [9] "Endless Pool" which was more inexpensive than SwimEx by James Murdock. Driving means (for 315L/s [5,000 U.S. gallon /]) of the water comprised of a hydraulic pump installed particularly in a driven large-scale propeller and the tunnel for the stainless steel steel water cycle is installed in this pool in a stainless steel steel pool covered by vinyl-related liner. The drive machine set up in a pool becomes the obstacle, and the effective space is small to some extent, and the current is limited to the use use because width is smaller than SwimEx, but there is the user to be equal as for the evaluation if I say by only about swimming. Since birth, the system of Endless Pool is copied from by other companies. I announced the unit which incorporated a patent propeller type promotion room in the acrylic bookbinding body which was available for mass production, and, at the mid-1990s, "Master Spas" (master spa) [11] brought the benefit of the 高容水量式駆動流水 pool in the "swimming spa" market. The Michael Phelps Signature Swim Spa series that Bob Lauter, CEO of Master Spas company designed is the representative model.
In the same 1990s, "Swim Gym" (swimming gym) [12] and "Riverflow" (river flow) [13] using a propeller-type drive system come up in the market. I can install these driving means in the position away from a pool. The perpendicular expression propeller changing 158L/s (for 2,500 U.S. gallon /) be wrapped up in big PVC (polyvinyl chloride) pipe, and the pipe is incorporated in the concrete wall of the existing pool. It is said that the running water created in this is equal to a thing of Endless Pool.
Running water outbreak system for the existing pool
To the representative thing of the device which an existing pool can use, there is Stream (stream) [16] which "Fastlane" (fast lane) [15] of Endless Pool Corporation, SwimEx Corporation announced in 2012 including BaduStream[14] of Speck Pumps company. Two of the latter are propeller types with both, but Fastlane be wrapped up in Stream with a super perpetuity polymer designed like outdoor furniture whereas they use a stainless steel machine waking up a current to install in a 5HP drive motor and the pool side that I placed particularly and it is quiet and is a charge type, the automatic portableness simple substance unit which is setting-free.
