We offer eccentric inertial training and sports rehabilitation courses, adapted to the needs of each user.
The training possibilities are very wide. They include theoretical and practical knowledge, multidisciplinary exercises with conical pulleys, flywheels and also the analysis of the session through specific software.
We have professionals in several cities: university professors, physical trainers, experts in inertial training, physiotherapists and other collaborators. We have been working with inertial methodology for +15 years.
We also offer possibilities to practice the development of PROINERTIAL® devices for free in first person. You can write to us to receive more information.
Here are some of the courses that collaborators already offer:
- FISIOCAMPUS. INERTIAL METHODOLOGY IN THE READAPTATION OF THE INJURED ATHLETE.
ASSESSPORT ACADEMY. BASES OF THE DEVELOPMENT OF THE ECCENTRIC FORCE.
We also have video tutorials on the basic use of inertial systems and methodological principles.
INERTIAL SYSTEMS: BASIC PRINCIPLES. FLYWHEEL AND CONICAL PULLEY
In the field of health and sport, the development of inertial systems originated in the late 1980s at the Karolinska Institute (Sweden) by Professors H. Berg and P. Tesch. Due to the loss of muscle mass by astronauts who spent long periods on space stations, non-gravitational muscle work was required.
In Spain, the first inertial devices were introduced by doctoral professor Josep. Mª Padullés in 1998, at the National Institute of Physical Education of Barcelona (INEFC), for analysis and study in a research laboratory. Since then, these training systems have continued to be improved both in the fields of elite sports, any sports and fitness practice such as physiotherapy and sports rehabilitation.
Inertial resistance is based on mass or inertia (resistance to change of state of motion) when speed is applied to a flywheel. The puck begins to rotate due to the action performed in the concentric phase of the exercise and then slows down in the second eccentric phase of the movement when resistance is offered.
We find a flywheel that is fixed to a shaft from which the traction is carried out. By pulling in the first phase, we accelerate it. Afterwards, the disk would continue to rotate but if we have a rope or girth that has reached the end of its travel, it will again wind on the same axis. We can perform a traction in the second phase of the exercise to prevent the disk from continuing to rotate in the same direction.
Inertial systems (commonly called isoinertial) can be grouped into 2 families: the flywheels and the conical pulleys.
In the flywheels we have a steering wheel attached to a traction shaft and in the conical pulleys, it also has a coupled cone that allows the working radius to be varied, thus being able to more easily modify the speed and resistance of the exercise. In the lower part of the cone (greater radius) we can execute the exercise with greater speed and less resistance. On the other hand, in the upper part of the cone (smaller diameter), we will have to make a greater force to accelerate the system. In both teams, weights can be added to increase resistance by adding inertia.
These mechanical structures allow you to work and offer resistance throughout the exercise range, in the so-called CEA (shortening-stretching cycle). There is continuous resistance in the two phases of exercise, both in the first concentric phase (contraction in muscle shortening) and in the second eccentric phase (lengthening the muscle). Therefore, these inertial devices allow a great variety of exercises at different intensities and individually, in addition to easily exercising the muscle in eccentric phase with the possibility of offering high workloads.
In inertial devices, eccentric overload, sometimes referred to as negative, allows further stretching of the muscle to occur. Here a greater tension or force is produced by the sum of the active and passive elements. Through these equipments the individual can perform explosive exercises, which favors speed and power or also achieve high resistance.
