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.
Rowing is one of the few non-weight bearing sports that exercises all the major muscle groups, including quads, biceps, triceps, lats, glutes and abdominal muscles. The sport also improves cardiovascular endurance and muscular strength. High-performance rowers tend to be tall and muscular: although extra weight does increase the drag on the boat, the larger athletes' increased power tends to be more significant. The increased power is achieved through increased length of leverage on the oar through longer limbs of the athlete. In multi-person boats (2,4, or 8), the lightest person typically rows in the bow seat at the front of the boat.

At the junior level (in the United States), regattas require each rower to weigh in at least two hours before their race; they are sometimes given two chances to make weight at smaller regattas, with the exception of older more prestigious regattas, which allow only one opportunity to make weight. For juniors in the United States, the lightweight cutoff for men is 150.0 lb.; for women, it is 130.0 lb. In the fall the weight limits are increased for women, with the cutoff being 135 lb.
Women row in all boat classes, from single scull to coxed eights, across the same age ranges and standards as men, from junior amateur through university-level to elite athlete. Typically men and women compete in separate crews although mixed crews and mixed team events also take place. Coaching for women is similar to that for men. The world's first women's rowing team was formed in 1896 at the Furnivall Sculling Club in London.
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.
Concept2 is full of athletes. Some of these athletes come from the core sports of our business like rowing, Nordic skiing and cycling. Others are CrossFitters, runners, equestrians, golfers, snowboarders and tennis players. For the employees who haven’t spent much time in a boat, we make sure to offer the opportunity each summer. This year, we headed up to Craftsbury Sculling Center so that our employees with less experience behind the oar could try rowing.
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.
At the current state of the art, indoor rowers which utilize flywheel resistance can be categorized into two motion types. In both types, the rowing movement of the user causes the footrests and the seat to move further and closer apart in co-ordination with the user's stroke. The difference between the two types is in the movement, or absence of movement, of the footrests relative to ground.
Head races are time trial / processional races that take place from autumn (fall) to early spring (depending on local conditions). Boats begin with a rolling start at intervals of 10 – 20 seconds, and are timed over a set distance. Head courses usually vary in length from 2,000 metres (1.24 mi) to 12,000 metres (7.46 mi), though there are longer races such as the Boston Rowing Marathon and shorter such as Pairs Head.
Rowing has long been recognized as the perfect aerobic pursuit, with naturally smooth and flowing movements that don't tax the joints but do boost the heart rate. Now you can take your rowing experience to the next level with the commercial-quality WaterRower Club rowing machine. Using the same principles that govern the dynamics of a boat in water, the WaterRower Club is outfitted with a "water flywheel" that consists of two paddles in an enclosed tank of water that provide smooth, quiet resistance, just like the paddles in an actual body of water. As a result, the machine has no moving parts that can wear out over time (even the recoil belt and pulleys don't require lubricating or maintaining). More significantly, the water tank and flywheel create a self-regulating resistance system that eliminates the need for a motor. As with real rowing, when you paddle faster, the increased drag provides more resistance. When you paddle slower, the resistance is less intense. The only limit to how fast you can row is your strength and your ability to overcome drag. And unlike conventional rowing machines, which tend to be jerky and jarring, the WaterRower Club is remarkably smooth and fluid.
