Isoinertial
From Wikipedia, the free encyclopedia
Isoinertial denotes a type of resistance used in exercise training which maintains a constant inertia throughout the range of motion, facilitating a constant resistance and maximal muscle force in every angle.
The term isoinertial derives from the words iso (same) and inertial (resistance), which in one terminology describes the primary concept of the isoinertial system, or expressing the same inertia in both the concentric and the eccentric phases of muscle contraction.
Since the late eighties, during long-duration space travel, was placed as a problem as the ability to maintain power the muscles of astronauts engaged in missions, given that the absence of gravity led to an environment in which they experienced atrophy of the musculoskeletal system, no longer called to support the load of the body weight, as well as a reduction in bone mineral density. Studies and research carried out about a solution that led to the strengthening of muscles of astronauts and subsequently, over the years, has become a method of muscle training very useful for preservation, prevention and rehabilitation. In practice it was created a flywheel training system for resistance training with a belt and a flywheel that, driven by the belt, controlling a process which generated movement regardless of the strength of gravity.
