An easy way to summarize the function of motorized resistance machines is that they use technology to create, measure, and report human output in training.

While some machines simply create resistance and don’t report much data on how that load interacts with a human, the benefit of specific resistance modes is the central driver to adopting such equipment.

A recent study showed that a combination of eccentric overload, isokinetic strength training and ballistic training yielded better results than both Olympic weight lifting and tradition weight training.

Typical research and rehabilitation machines provide isokinetic resistance, where the device manipulates force and speed to be uniform in velocity by matching resistance up and down.

In the past, research and sport science used simple assessments like hamstring and quadriceps testing to observe changes or profiling, but much of it was limited due to the open chain muscle actions and lack of relationship to complex movement and performance.

The typical Isotonic resistance is air driven resistance, where there is no inertial component present.

Ballistic One of the advantages with motorized equipment is the possibility to control inertia.

If rehabilitation, human performance, research, and health promotion interest you, you will benefit from this outline and these recommendations.

The cornerstone of an electronic resistance machine is that the resistance comes from a motorized option, usually controlled by a combination of the settings, the user, and sometimes a computer.Typical barbells, flywheels, and cable machines don’t require electric power to change their resistance, so any equipment that can run without power but uses technology cannot fall into this category of product.Plenty of traditional squat racks and platforms are made “smart” because they use sensors and displays, but the technology doesn’t affect the resistance type.If power and programming are not adjusting the load, the device is simply not motorized resistance—it’s just a traditional piece of equipment with technology features.Most, if not all, equipment not only produces resistance, but also measures the output of the resistance from the user.Isotonic is just creating a change in tension on muscle, and nearly any exercise outside of isometric training (static contraction) will provide a dynamic contraction.
