When a person enters the world of fitness with the intention of toning and maintaining in shape their muscular structure, the image that most frequently goes around their head is lifting-moving weights, with different machines, as a routine to make the muscles work and acquire strength. These routines are based on the belief that the muscle fiber is exercised by making the effort to move weight against the force of gravity, and that the continuous repetition of these movements ends up causing the hypertrophy of the muscle that is being sought. Although the experience of many years shows that this is one of the possible ways, the truth is that modern theories and studies on strength training reinforce the idea that there are faster, safer and more efficient ways of working the muscular structure.
Isoinercial technology was developed at the end of the last century to respond to the problem of loss of muscle mass detected in astronauts who spent long periods in space, in environments absent of gravity. If in such places it is impossible to do weight-lifting routines that help keep the muscle in shape, how else can you exercise the muscle fiber so that it does not atrophy? The isoinercial technology solved the problem by using flywheels of inertia, wheels able to turn the turn into resistance. We will explain it in the simplest way possible:
In the phase of contraction of the muscle, concentric phase, we cause the rotation of the flywheel and generate kinetic energy inside the accessory. This accumulated energy must be dissipated, and this occurs in the relaxation phase of the muscle fiber, eccentric phase, which is when the flywheel turns in the opposite direction and causes a resistance that must be stopped by the muscle that was working. If we realize, using exercise equipment based on isoinertial technology, we generate strength in all phases of exercise, when we contract fiber, when we hold the contracted muscle, and when we relax it, the final moment in which we must fight to stop the resistance caused by the accumulation of kinetic energy. That is the big difference compared to the traditional exercise based solely on overcoming the force of gravity with bars, dumbbells, etc.
As benefits of this technology we find a greater efficiency of movements, which results in the construction of muscle fiber of higher quality in a shorter period of time, and with an addition that is deeply valued by experts, whether they are physical trainers or physiotherapists: the risk of injuries is considerably reduced. We will dedicate a new article to this issue soon. Stay tuned.
