SOLE Elliptical machines: The science behind the machines.
There is a lot of hoopla in the fitness equipment industry concerning Elliptical Trainers and which one has the best Biomechanics and Ergonomics. You'll also hear terms like "Plantar flexion" and "Erector spinae rotation" and "Ulnar deviation". We at Sole feel you shouldn't have to have a degree in orthopedics to buy an Elliptical Trainer but you should understand the words Biomechanics and Ergonomics. Here are the official definitions:
Biomechanics: The study of the anatomical principles of movement.
Ergonomics: (from Greek ergon work and nomoi natural laws) The study of optimizing the interface between human beings, and the designed objects and environments they interact with.
Simply stated Biomechanics is the study of how your body moves and Ergonomics is the study of how to build a machine that moves like your body does so you feel comfortable using the machine. For an Elliptical Trainer this means it should have a smooth, continuous foot motion, an Ellipse pattern (The pattern that your foot travels during exercise) that is level and simulates walking or running.
