What makes tethered swim training effective is the opportunity to do swim strength training with swim specific movement. Swimming against the resistance of a tether strengthens your muscles in exactly the movement range, speed and pattern that you practice. Tethered swimming builds muscle strength by resistance. By incorporating assisted and resisted strength training in the water, muscle memory is achieved which translates into increased swimming power. Muscle memory is a state in which the muscles “memorize” a pattern of activating the maximum amount of muscle tissue for the given activity.
What makes tethered swimming different from lifting weights is that muscle memory is highly specific. Land strength training doesn’t translate well in water activities. If you perform strength-training exercises in swim-specific movements, you are more likely to transform them into swimming power.
