Rowing is a cyclic (or intermittent) form of propulsion such that in the quasi-steady state the motion of the system (the system comprising the rower, the oars, and the boat), is repeated regularly. In order to maintain the steady-state propulsion of the system without either accelerating or decelerating the system, the sum of all the external forces on the system, averaged over the cycle, must be zero. Thus, the average drag (retarding) force on the system must equal the average propulsion force on the system. The drag forces consist of aerodynamic drag on the superstructure of the system (components of the boat situated above the waterline), as well as the hydrodynamic drag on the submerged portion of the system. The propulsion forces are the forward reaction of the water on the oars while in the water. Note also that the oar can be used to provide a drag force (a force acting against the forward motion) when the system is brought to rest.
At the collegiate level (in the United States), the lightweight weight requirements can be different depending on competitive season. For fall regattas (typically head races), the lightweight cutoff for men is 165.0 lb. and 135.0 lb. for women. In the spring season (typically sprint races), the lightweight cutoff for men is 160.0 lb., with a boat average of 155.0 lb. for the crew; for women, the lightweight cutoff is 130.0 lb.[48]
* While there is nothing to adjust from row to row on the WaterRower, it is possible to increase or decrease the level of resistance by changing how much water you put in the drum. The monitor is pre-calibrated to match 17 liters of water, but you can change that if you want. More than 17 liters = more resistance, up to the max fill line. This is not something you'll want to change frequently, it's more of a set-it-and-forget-it thing.

There are many differing sets of rules governing racing, and these are generally defined by the governing body of the sport in a particular country—e.g., British Rowing in England and Wales, Rowing Australia in Australia, and USRowing in the United States. In international competitions, the rules are set out by the world governing body, the Fédération Internationale des Sociétés d'Aviron (FISA). The rules are mostly similar but do vary; for example, British Rowing requires coxswains to wear buoyancy aids at all times, whereas FISA rules do not.
Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound and vibration enhancing the WaterRower's quietness and smoothness of use. The WaterRower's patented WaterFlywheel has been designed to emulate the exact dynamics as a boat moving through water; the objective of the exercise of rowing.
Do you want pre-set workouts? Are you one of those people who can't go for a run without an app, a training plan, and a corresponding diet worksheet? Even if you don't take it that far, pre-programmed workout routines can really enhance your rowing machine experience by varying your workouts and guaranteeing you a challenging session. If you're trying to decide between two machines, you could do worse than to choose one with a good range of built-in workouts.
```As with any fitness activity, it’s important to exercise with proper technique, however. The big muscles in the legs are where most of the workout action should be. Injury to the lower back can occur from bending too far forward in the row. It’s best to maintain a upright 90 degree angle to the rowing machine’s seat and slider bar. Using the legs for the motion rather than relying as heavily on the back or arms can help reduce the chance of muscle pulls or other related injuries. Always check with a physician before starting any new fitness regimen.

```One of the major deciding factors between water and air rowers is price. Water rowing machines are often found in higher price ranges with the lowest model going for \$700 and the best models starting around \$1,100. Air rowers are found in every price range starting at \$300 and going as high as \$1,000+. The affordability of air rowing machines makes them very popular.

Most races that are held in the spring and summer feature side by side racing, or sprint racing, sometimes called a regatta; all the boats start at the same time from a stationary position and the winner is the boat that crosses the finish line first. The number of boats in a race typically varies between two (which is sometimes referred to as a dual race) to eight, but any number of boats can start together if the course is wide enough.
The WaterRower Natural is hand crafted in solid Ash and stained Honey Oak for consistency of color. Each machine has been hand finished with Danish Oil giving a deep lustre an warmth to the wood. Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound and vibration enhancing the WaterRower's quietness and smoothness of use.
When feet are in position and you are seated, ensure you are sitting in a tall yet relaxed position. Try to feel as if you are sitting on your ‘sit’ or ischia bones and rock slightly forwards and backwards on these bones. Your body weight will move from the front to the back of the seat. Ensure you are sitting with a locked core, shoulders relaxed and head looking forwards.
Ever since the earliest recorded references to rowing, the sporting element has been present. An Egyptian funerary inscription of 1430 BC records that the warrior Amenhotep (Amenophis) II was also renowned for his feats of oarsmanship. In the Aeneid, Virgil mentions rowing forming part of the funeral games arranged by Aeneas in honour of his father.[10] In the 13th century, Venetian festivals called regata included boat races among others.[11]

Fetch is the distance over which the wind interacts with the water surface to creates waves. The longer the fetch the bigger (higher) the waves are. If the shore (green in the diagram) is a hill, there will be a wind shadow which gives protection from the wind, but even if the shore is flat as a pancake and gives no protection, the waves become progressively smaller as you for upwind to the shore. Thus, rowing upwind toward shore is always an escape from waves.

The machine was easy to put together and worked well mechanically. The problem is the electronic monitor. The strokes/min registered as double the actual pace, and the distance registered as 1/10th the actual distance. I contacted customer support via email and their response was slow and inadequate. I am returning the machine and plan to buy a WaterRower.
The Challenge AR has the capability to allow the rower to control and adjust the resistance from “Feather light” to “Olympic sprint” delivering a silky smooth resistance to the user’s effort and instantaneous response to input with no “flat sport”.  With water resistance being the most accurate manner in which to simulate actual outdoor rowing, the Challenge AR provides a smooth and consistent sensation throughout the range of motion of the exercise experience.

This type of machine provides a smooth action with little wear and tear to the mechanism, and the flywheel itself could help to keep you cool as you work out. It's worth noting that although water rowers aim for a realistic rowing feel, competitive rowers often use air rowers for land training. They tend to be less expensive than water-powered rowing machines, as well.
The tank of the WaterRower Oxbridge Rower is made from polycarbonate, one of the strongest plastics available. It is virtually indestructible. The tank is sealed and can be filled with municipal water via a small opening closed by a stopper. This water typically contains enough chlorine to remain clear for some time. After exposure to light, the chlorine will degrade; the chlorine tablets should be added periodically.

In the 1950s- and 1960s, more sports coaches began to use rowing machines for training and assessment of athletes' performance. One such rower developed at this time was the Harrison-Cotton machine, the brainchild of John Harrison of Leichhardt Rowing Club in Sydney and Professor Frank Cotton, produced by Ted Curtain Engineering. This was the very first piece of equipment able to measure athletic power with great accuracy, and it also imitated the actual experience of rowing more closely than any previous rowing machine.
On a rowing machine, you don’t want to be wearing clothes that are too baggy as the fabric can get caught between the seat and the beam it slides on.  It’s not a disaster if that happens, but it can get annoying if your shorts keep getting caught there while you’re trying to get a serious workout.   It’s better to wear shorter, tighter-fitting shorts (nothing ridiculous), but just enough to ensure it doesn’t the material doesn’t hang down.

The Verified Sustainable Hardwoods used for the WaterRower are sourced from the Appalachian Mountain region of the eastern United States, where planting rates exceed harvest rates by an average multiple of 2.29. The Appalachian Hardwood Timber resource includes more than 65.4 million acres in the eastern United States and provides the world with a bounty of the finest hardwood species.
Infinitely Variable Resistance: The benefit of a water resistance rower is that it most closely simulates a boat moving through water. When rowing the resistance is due to the effect of fluid drag acting on the boat. Go faster, resistance increases. Go slower resistance decreases. Importantly, the user chooses; regardless of age, gender, size or fitness. The WaterRower M1 LoRise's patented WaterFlywheel emulates this naturally self-paced benefit of rowing. This is a workout you can start benefitting from immediately, regardless of experience!
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.
```In addition to this, certain crew members have other titles and roles. In an 8+ the stern pair are responsible for setting the stroke rate and rhythm for the rest of the boat to follow. The middle four (sometimes called the "engine room" or "power house") are usually the less technical, but more powerful rowers in the crew, whilst the bow pair are the more technical and generally regarded as the pair to set up the balance of the boat. They also have most influence on the line the boat steers.

The first international women's races were the 1954 European Rowing Championships.[54] The introduction of women's rowing at the 1976 Summer Olympics in Montreal increased the growth of women's rowing because it created the incentive for national rowing federations to support women's events. Rowing at the 2012 Summer Olympics in London included six events for women compared with eight for men.[55] In the US, rowing is an NCAA sport for women but not for men;[56] though it is one of the country's oldest collegiate sports, the difference is in large part due to the requirements of Title IX.
Modern rowing as a competitive sport can be traced to the early 10th century when races were held between professional watermen on the River Thames in London, United Kingdom. Often prizes were offered by the London Guilds and Livery Companies. Amateur competition began towards the end of the 18th century with the arrival of "boat clubs" at the British public schools of Eton College, Shrewsbury School, and Westminster School. Similarly, clubs were formed at the University of Oxford, with a race held between Brasenose College and Jesus College in 1815. At the University of Cambridge the first recorded races were in 1827. Public rowing clubs were beginning at the same time; in England Leander Club was founded in 1818, in Germany Der Hamburger und Germania Ruder Club was founded in 1836 and in the United States Narragansett Boat Club was founded in 1838 and Detroit Boat Club was founded in 1839. In 1843, the first American college rowing club was formed at Yale University.

###### With the smaller boats, specialist versions of the shells for sculling can be made lighter. The riggers in sculling apply the forces symmetrically to each side of the boat, whereas in sweep oared racing these forces are staggered alternately along the boat. The sweep oared boat has to be stiffer to handle these unmatched forces, so consequently requires more bracing and is usually heavier – a pair (2-) is usually a more robust boat than a double scull (2x) for example, and being heavier is also slower when used as a double scull. In theory this could also apply to the 4x and 8x, but most rowing clubs cannot afford to have a dedicated large hull which might be rarely used and instead generally opt for versatility in their fleet by using stronger shells which can be rigged for either sweep rowing or sculling. The symmetrical forces also make sculling more efficient than rowing: the double scull is faster than the coxless pair, and the quadruple scull is faster than the coxless four.

This is a company known for quality as well as stewardship for over 20 years. WaterRower hand-crafts their rowing machines to be more than just a workout machine, but also a work of art as well. Also, WaterRower is and has been on the cutting edge of environmental sustainability with their use of the best hardwoods coming from renewable forests. We’re in excellent hands here.

In the empty-lung technique, rowers inhale during the drive, and exhale during the recovery so that they have empty lungs at the catch. Because the knees come up to the chest when the lungs are empty, this technique allows the rower to reach a little bit further than if the lungs were full of air. Full lungs at the release also can help the rower to maintain a straighter back, a style encouraged by many coaches.
At the collegiate level (in the United States), the lightweight weight requirements can be different depending on competitive season. For fall regattas (typically head races), the lightweight cutoff for men is 165.0 lb. and 135.0 lb. for women. In the spring season (typically sprint races), the lightweight cutoff for men is 160.0 lb., with a boat average of 155.0 lb. for the crew; for women, the lightweight cutoff is 130.0 lb.[48]

Most of the Waterrower range is made of wood harvested from the sustainably managed Appalachian forests of the eastern United States. The machines are extremely well built and are beautiful to look at coming in Ash, Oak or Cherry wood. If you are concerned about having an exercise machine in a living area, then one of the wooden models will fit right in to your living room. They are also extremely quiet in operation due to the wooden construction and the use of a strap rather that a chain. The only thing you can really hear is the swishing sound of the water in the tank as you pull giving you the feeling that you are really on the river!
The first known "modern" rowing races began from competition among the professional watermen in the United Kingdom that provided ferry and taxi service on the River Thames in London. Prizes for wager races were often offered by the London Guilds and Livery Companies or wealthy owners of riverside houses.[10] The oldest surviving such race, Doggett's Coat and Badge was first contested in 1715 and is still held annually from London Bridge to Chelsea.[12] During the 19th century these races were to become numerous and popular, attracting large crowds. Prize matches amongst professionals similarly became popular on other rivers throughout Great Britain in the 19th century, notably on the Tyne. In America, the earliest known race dates back to 1756 in New York, when a pettiauger defeated a Cape Cod whaleboat in a race.[13]

According to Fritz Hagerman, Ph.D., a professor in the Biological Science Department at Ohio University, “Competitive rowers expended almost twice the number of calories on a 2,000-meter course as a runner in a 3,000-meter steeplechase.”1 However, since rowing is low impact, you will not experience the same wear and tear on your body that you would if you were a runner. Plus, you build strength in your upper body and core.
The coxswain (or simply the cox) is the member who sits in the boat facing the bow, steers the boat, and coordinates the power and rhythm of the rowers - by communicating to the crew through a device called a cox box and speakers. They usually sit in the stern of the boat, except in bowloaders where the coxswain lies in the bow. Bowloader are usually seen as the coxed four and coxed pair type of boat.
