Types of Rowing Machines
Indoor rowing has built a following of its own kind and is becoming more and more popular these days. Latest designs are constantly introduced in the market. The basic classification of the rowing machines is on the basis of the type of resistance they use.
There are two groups in the types of resistances that rowing machines use. The first is Piston Resistance. This type uses a hydraulic piston that is attached to the handle. The length of the rower handles is usually adjustable but it does not change while rowing. So the trajectory of the handle once fixed remains same throughout the workout. That means that the path that is taken while pulling is the same for returning. Such models usually have a fixed seat position. This means that legs can’t be used to push in these models.
The second group, brake flywheel resistance has three types: Magnetic Resistance, Air Resistance and Water resistance. All the three models are grouped under brake flywheel resistance, as they all have the same basic design, have a flywheel that is connected to the handle with either a chain or rope. And since all of them have a flexible medium by which they connect the handle and the flywheel, therefore it is possible for a rower to have a different trajectory during pull and return. Also all the models offer movable seats. That makes the experience close to reality. In the Magnetic Resistance models, the brake uses an electromagnet that engages the brakes. In these models the braking resistance can be adjusted. In the Air Resistance models, air-fins are used which are like the blades of a fan. The air pressure they take onto themselves causes braking. They use a damper to control the resistance. As they are very similar to fans, their speed is measured through sensors by the dissipated amount of energy. The last type Water Resistance models are very similar to the Air resistance models as they have the same type of fins on the flywheel, but instead of air they use water to resist movement. The flywheel in these models is submerged in water.
