Another added benefit of aqua resistance training is that it allows you to work the muscles in paths of motion that land-based equipment does not. For example, if you were to perform a bicep curl with a dumbbell, you would only be working the bicep muscle. However, the same exercise performed in water would force you to use the triceps when you return the arm to the extended straight position. These benefits of water resistance can be readily applied to various sports training. For example, a tennis player can mimic the backhand and forehand movement of a tennis swing.
Golfers can mimic a golf swing.
On land, the path of these swings elicit changes in leverage along with the effects of gravity, depending on where the body is positioned in relation to the swing. This creates mechanical advantages and disadvantages. Aquatic training, on the other hand, allows for accomodating variable resistance throughout the entire path of motion, thereby optimizing its effectiveness and eliminating mechanical advantages and disadvantages. One of the most important benefits of using a physioball in a resistance training program is the improved spinal stabilization and strength that it produces. In conventional resistance training, the bench or seat stabilizes the body, whereas in physioball training, the body must work to stabilize itself.
