In addition to the aforementioned improved "on the water" sensation experienced by the user of a "dynamically balanced" rowing ergometer, there are also bio-mechanical and power delivery advantages. Bio-mechanically, throughout all phases of the stroke, the user's mass moves only a small distance relative to ground, therefore the user is not subject to the inertial stresses associated with the abrupt fore and aft directional changes experienced on a "stationary" rowing ergometer. With respect to power delivery: Casper Rekers, inventor of the "dynamically balanced" rowing ergometer, "performed tests comparing the indicated power output of a "stationary" versus a "dynamic" rowing ergometer - the subject gained 10-20% power output in the second case, representing additional power that could be applied to the flywheel instead of accelerating the bodyweight" of the user on the seat rail.
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.
Another negative point for me is the angle of the seat. Unlike the Concept2, it has a slight backward angle, which makes it easier to maintain good form at the end of the stroke. Given that the Waterrower has greater resistance at the catch, it puts more pressure on the lower back at this point making it uncomfortable for people like myself with lumbar spine problems.
We’ll be the first to admit that when the weather is nice we’d rather be outdoors than inside working out. Concept2 employees are active outside year-round in all kinds of weather skiing, running, mountain biking, paddling, road cycling, hiking… and rowing! We encourage you to spend some time outdoors, too. But there are good reasons to keep in touch with your favorite indoor workouts in spring and summer. Continue Reading ›
The WaterRower Classic is outfitted with a Series 4 performance monitor that's designed to balance technical sophistication with user-friendliness. The monitor--which includes six information and programming windows, six QuickSelection buttons, and three navigation buttons--displays your workout intensity, stroke rate, heart rate, zone bar, duration, and distance. Plus, the monitor is compatible with an optional heart rate chest strap and receiver, which helps you optimize your workout and achieve your exercise objectives.
There isn’t a prescribed stroke rate for this workout, but it is important to make sure that you are keeping full length on the slide (legs). Be careful not to shorten up or scramble, as this will negatively affect technique and posture. The target is to hold the lowest average split possible, at a sprint pace that would be unsustainable over longer distances, for all four pieces. According to Frandsen, a competitive rower would “take advantage of every second of rest to ensure that each piece is of the highest intensity.”
The recovery phase follows the drive. The recovery starts with the extraction and involves coordinating the body movements with the goal to move the oar back to the catch position. In extraction, the rower pushes down on the oar handle to quickly lift the blade from the water and rapidly rotates the oar so that the blade is parallel to the water. This process is sometimes referred to as feathering the blade. Simultaneously, the rower pushes the oar handle away from the chest. The blade emerges from the water square and feathers immediately once clear of the water. After feathering and extending the arms, the rower pivots the body forward. Once the hands are past the knees, the rower compresses the legs which moves the seat towards the stern of the boat. The leg compression occurs relatively slowly compared to the rest of the stroke, which affords the rower a moment to recover, and allows the boat to glide through the water. The gliding of the boat through the water during recovery is often called run.
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!
A third non-elastic handle return strategy is disclosed in US patent, "Gravity Return Rowing Exercise Device" (US9878200 B2, 2018) granted to Robert Edmondson. As stated in the patent document, the utilization of gravity (ie: a weight) to take up the chain and return the handle eliminates the inevitable variability of handle return force associated with an elastic cord system and thereby ensures consistency between machines.
Rowing technique on the erg broadly follows the same pattern as that of a normal rowing stroke on water, but with minor modifications: it is not necessary to "tap down" at the finish, since there are no blades to extract from water; but many who also row on water do this anyway. Also, the rigid, single-piece handle enables neither a sweep nor a sculling stroke. The oar handle during a sweep stroke follows a long arc, while the oar handles during a sculling stroke follow two arcs. The standard handle does neither. But regardless of this, to reduce the chance of injury, an exercise machine should enable a bio-mechanically correct movement of the user. The handle is the interface between the human and the machine, and should adapt to the natural movement of the user, not the user to the machine, as is now the case. During competitions an exaggerated finish is often used, whereby the hands are pulled further up the chest than would be possible on the water, resulting in a steep angulation of the wrists - but even with a normal stroke, stop-action images show wrist angulation at the finish, evidence that the standard rigid, single-piece handle does not allow the user to maintain a bio-mechanically correct alignment of hands, wrists, and forearms in the direction of applied force. On the Concept 2 website "Forum", many regular users of the indoor rower have complained of chronic wrist pain. Some have rigged handgrips with flexible straps to enable their hands, wrists, and forearms to maintain proper alignment, and thereby reduce the possibility of repetitive strain injury. Rowing machine manufacturers have ignored this problem.
For those who are overweight or have existing joint problems, high-impact workouts may carry more risks than benefits. A rowing machine is a great alternative for those who are unable to perform weight-bearing exercises, such as running, hiking, walking, and yoga. The motion of rowing is natural and low impact, putting minimal stress on the joints. Like stationary bikes, rowers are great for injury prevention and are also an excellent way to strengthen and condition the knees after surgery. While back strain is a concern, you can minimize your risk by using correct rowing form. Good rowing posture lets your legs do the work, taking the pressure off your back. Check out #9 for more details on proper rowing technique.
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.
Ergometer rowing machines (colloquially ergs or ergo) simulate the rowing action and provide a means of training on land when waterborne training is restricted, and of measuring rowing fitness. Ergometers do not simulate the lateral balance challenges, the exact resistance of water, or the exact motions of true rowing including the sweep of the oar handles. For that reason ergometer scores are generally not used as the sole selection criterion for crews (colloquially "ergs don't float"), and technique training is limited to the basic body position and movements. However, this action can still allow a comparable workout to those experienced on the water.
In the patent record, means are disclosed whereby the chain/cable take-up and handle return are accomplished without the use of a spring or elastic cord, thereby avoiding the stated disadvantages and defects of this broadly used method. One example is the Gjessing-Nilson device described above. Partially discernable in the thumbnail photo, it utilizes a cable wrapped around a helical pulley on the flywheel shaft, the ends of this cable being connected to opposite ends of a long pole to which a handle is fixed. The obvious disadvantage of this system is the forward space requirement to accommodate the extension of the handle pole at the "catch" portion of the stroke. The advantage is that, except for small transmission losses, all of the user's energy output is imparted to the flywheel, where it can be accurately measured, not split between the flywheel and an elastic cord of variable, unmeasured resistance. If a similar system were installed on all rowing ergometers used in indoor rowing competitions, consistency between machines would be guaranteed because the variability factor of elastic cord resistance would be eliminated, and this would therefore ensure that the monitor displayed actual user energy input.
According to fitness experts, water resistance is by far the most efficient technology used in a rowing machine, and the result is a realistic rowing experience that provides a better workout with smoother and more fluid rowing. These machines use a paddle that’s suspended in a tank of water, providing a realistic sensation of rowing outdoors. Extremely quiet running, as you row the only sound you’ll hear is the gentle splashing of water moving with each stroke, which serves to enhance the realistic experience of this style of rower.

Water resistance models consist of a paddle revolving in an enclosed tank of water. The mass and drag of the moving water creates the resistance. Proponents claim that this approach results in a more realistic action than possible with air or magnetic type machines. "WaterRower" was the first company to manufacturer this type of rowing machine. The company was formed in the 1980's by John Duke, a US National Team rower, and inventor of the device (1989 US Patent US4884800A). At that time, in the patent record, there were a few prior art fluid resistance rowing machines, but they lacked the simplicity and elegance of the Duke design. From the 1989 patent Abstract: "... rowing machine features a hollow container that holds a supply of water. Pulling on a drive cord during a pulling segment of a stroke rotates a paddle or like mechanism within the container to provide a momentum effect."
The standard length races for the Olympics and the World Rowing Championships is 2 kilometres (1.24 mi) long; 1.5 kilometres (0.93 mi) - 2 kilometres (1.24 mi) for US high school races on the east coast; and 1,000 m for masters rowers (rowers older than 27). However the race distance can and does vary from dashes or sprints, which may be 500 metres (1,640 ft) long, to races of marathon or ultra-marathon length races such as the Tour du Léman in Geneva, Switzerland which is 160 kilometres (99 mi), and the 2 day, 185-kilometre (115 mi) Corvallis to Portland Regatta held in Oregon, USA. In the UK, regattas are generally between 500 metres (1,640 ft) and 2 kilometres (1.24 mi) long.
In 1995, Casper Rekers, a Dutch engineer, was granted a U.S. patent for a "Dynamically Balanced Rowing Simulator" (US5382210A). This device differed from the prior art in that the flywheel and footrests are fixed to a carriage, the carriage being free to slide fore and aft on a rail or rails integral to the frame. The seat is also free to slide fore and aft on a rail or rails integral to the frame. From the patent Abstract: "During exercise, the independent seat and energy dissipating unit move apart and then together in a co-ordinated manner as a function of the stroke cycle of the oarsman.". "RowPerfect" and "Oartec" are two companies which currently manufacture commercial embodiments of the Rekers device.
The “split” refers to how much time it would take you to cover 500 meters if you maintain that split. For example, if you are holding a 1:45 split, then it will take you 1 minute, 45 seconds to cover 500 meters. “It’s a great way to see if your training (and technique) is paying off with improved splits,” says Frandsen. You are able to program your workout in by going to “Select Workout,” then “New Workout,” and then inputting your work intervals based on time or distance, as well as your rest interval.
Rowing on an ergometer requires four basics phases to complete one stroke; the catch, the drive, the finish and the recovery. The catch is the initial part of the stroke. The drive is where the power from the rower is generated while the finish is the final part of the stroke. Then, the recovery is the initial phase to begin taking a new stroke. The phases repeat until a time duration or a distance is completed.
Yes! The mother of indoor rowing competitions is the CRASH-B Sprints, held annually in Boston. The Charles River All-Star Has-Beens started when the U.S. boycotted the Olympics in 1980 — during the same era that Concept 2 launched their Model A; necessity met opportunity. CRASH-B is still held with aplomb and doesn’t require any special qualification of its applicants.
