Rowing is a low impact sport with movement only in defined ranges, so twist and sprain injuries are rare. However, the repetitive rowing action can put strain on knee joints, the spine and the tendons of the forearm, and inflammation of these are the most common rowing injuries. [9]If one rows with poor technique, especially rowing with a curved rather than straight back, other injuries may surface, including back pains. Blisters occur for almost all rowers, especially in the beginning of one's rowing career, as every stroke puts pressure on the hands, though rowing frequently tends to harden hands and generate protective calluses. Holding the oars too tightly or making adjustments to technique may cause recurring or new blisters, as it is common to feather the blade (previously described). Another common injury is getting "track bites", thin cuts on the back of one's calf or thigh caused by contact with the seat tracks at either end of the stroke.
Wood is used for its unique visual appeal, but also for its ability to absorb sound vibration for smooth, quiet operation, as well as it's stable longevity. The Club edition rowing machine is handcrafted in solid ash wood and stained for color. It has been designed for high traffic or commercial areas, and its black rails have been styled to prevent scuffing. The other wooden components are finished in an attractive rosewood which is more resistant to soiling than the Natural model. Each machine has also been hand finished with Danish Oil and Urethane for protection.
One of the most common brand of ergometers is Concept2.[33] The company offers multiple types of models, including the Model D, Model E, and the dynamic rower. An updated Rowperfect brand of dynamic rowers, RP3, produces ergometers that more naturally mimic the feel and resistance of rowing in a shell on the water. It additionally, shows a dynamic force curve of power that provides the rower with detailed information about their stroke which they can use to improve technique and get stronger.[34]
Do you need a machine that folds up? If you've decided to avoid a water rower for space reasons, you may prefer a model that folds up for storage. Even better, some rowing machines have wheels fitted to them, so that once it's folded up, you can steer it to a storage space out of the way. You can find a foldable design in many magnetic and some air rowers.
There is much to love about the WaterRower--and I do love it--but I would echo others' comments that although the seat rolls solidly and smoothly on the wood rails, the seat itself is very hard (I use a gel seat pad I bought for my hard fiberglass kayak seat), and the footpads are in need up rethinking and upgrading--the cheap plastic doesn't let you row in socks or barefoot and is not really worthy of a machine that is otherwise a stunning piece of engineering and a beautiful one as well. As one other person noted about his machine, my machine made a clicking noise on the return stroke, so I had to adjust the wheel underneath the top rail that connects to the footpad and pull it away gently from where it was rubbing against another component. Also, be warned: the instruction booklet is in the DVD case. I did not see the little sticker on the case telling me that, thinking I'd wait to watch the DVD until after I'd assembled it. But WaterRower has a copy of the assembly instructions on their website, along with a video (I found the written ones better and easier to follow), so I was able to assemble it with no difficulty.
Function plays a large role in defining good design. When designers look at an object, they don't just consider its aesthetic appearance; they should also challenge it to be more versatile, to respond to the user's need, or to achieve its purpose more elegantly. Good design has the capacity to solve problems that sometimes we didn't even know we had. This is one of the ways design touches and enriches our everyday life.

I kayak (ocean and flat water, not river), so I was drawn to the WaterRower over a flywheel type rower (which I have used in gyms) because I wanted to hear the sound of the water, which I miss hearing against the hull of the boat during the winter when I can't get out on the lake. I also like the way the paddles engage in the water; it's a very smooth pull and release, and moving the mass of the water instead of a dialed down tension feels more natural. As someone else also commented, the seat (at least on the wood version) is incredibly smooth and solid; no wobbling at all. I generally listen to music on my Nordic Track ski machine, but with the WaterRower I am content to listen to the sound of the water; working out on this is somehow both energizing and calmingly meditative at the same time. In the event that you want to use it while watching tv (this is one use to which I wanted to put it), it is quiet enough to hear the tv without having to turn it up.

In deep water the speed (or velocity) of a water wave depends only on its wave length. Specifically, the speed is proportional to the square root of the wavelength. Thus, the longer the wave length, the faster the wave, or vice versa. The speed of a single wave is called the phase speed. Amazingly, the speed of a packet of waves (the group speed) is often not the same.

Although some rowing machines are made of space-age, super-sweat-resistant metals, you still want to wipe off the equipment after a sweaty workout.  These machines are usually constructed with a lot of various materials and salty sweat can be very corrosive.  Keeping your rowing machine clean can go a long way toward extending its life, and its appearance.
When waves run into water moving in the opposite direction, they are slowed, just as if they were approaching a beach. Wave length becomes shorter, wave height higher, and they may break. A good (bad) example of this is an ebb current flowing out of Raccoon Strait into waves coming in from the Golden Gate. Good rough water training, if that’s what you want.

Both the air rower and water rower machines are very popular choices of rowing equipment, particularly the former type. They have been around in the 80s, and many consumers and those that have tried them in gyms consider the equipment to be the best type ever. These air resistance equipment, often regarded as Ergometers, is the standard base model for indoor rowing sport.
 The amount of water in the tank simulates the weight of the boat and crew, the more water in the tank the heavier the boat and crew. The standard Calibration Level is Level 17. If the user is lighter in weight, Level 15-16 can be used. If the user is heavier in weight, level 18-19 can be used. The maximum level to fill the tank is Level 19. DO NOT fill above the maximum level – this could void the warranty.
Founded in 1818, Leander Club is the world's oldest public rowing club.[17] The second oldest club which still exists is the Der Hamburger und Germania Ruder Club which was founded 1836 and marked the beginning of rowing as an organized sport in Germany.[18] During the 19th century, as in England, wager matches in North America between professionals became very popular attracting vast crowds. Narragansett Boat Club was founded in 1838 exclusively for rowing. During an 1837 parade in Providence, R.I, a group of boatmen were pulling a longboat on wheels, which carried the oldest living survivor of the 1772 Gaspee Raid. They boasted to the crowd that they were the fastest rowing crew on the Bay. A group of Providence locals took issue with this and challenged them to race, which the Providence group summarily won. The six-man core of that group went on the following year to found NBC in 1838.[19] Detroit Boat Club was founded in 1839 and is the second oldest continuously-operated rowing club in the U.S. In 1843, the first American college rowing club was formed at Yale University.[20] The Harvard–Yale Regatta is the oldest intercollegiate sporting event in the United States,[21] having been contested every year since 1852 (excepting interruptions for wars).
The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
