Definitions

  • the present invention refers to an apparatus for "isoinertial training", also defined as “flywheel training”.
  • This training method is widely established and spread in the area of physical exercise and has shown itself to be useful in training for various sporting disciplines, as well as in physical rehabilitation and injury preventions, thanks to its capacity of inducing physiological and neuromuscular adaptations which are beneficial for increasing muscle strength and hypertrophy.
  • the growing interest in physical activity and training, also at the amateur level, has accelerated research and development in the field, thus contributing to developing new working methods, new machinery and equipment, as well as the development of dedicated software for the performance of exercises that are more specific and innovative than traditional ones.
  • the technology of the isoinertial machines introduced above essentially relates to a system whereby the inertial mass of a flywheel produces resistance during both the concentric and eccentric phases of the exercise of the operator. This clearly distinguishes it from other ergometric devices (such as exercise bikes and rowing machines), in which the flywheel only exerts resistance during the concentric phase.
  • an isoinertial machine is commonly provided with a flywheel and a flexible traction member, generally a belt or a rope, which is unwound and rewound over the shaft of the flywheel itself in alternate directions. At the beginning of exercise, the traction member is wound partially or fully around this shaft.
  • the operator pulls the traction member, which begins to unwind from the shaft, causing the shaft itself and the connected flywheel to rotate.
  • the flywheel mass continues to rotate in the same direction, due to its inertia, rewinding the flexible traction member around the same shaft, albeit in the opposite direction.
  • the operator performs exercises by trying to slow down or halt the rewinding of the traction member in order to interrupt the exercise or start a new concentric phase whereby the traction member begins to unwind from the shaft once more.
  • the user can change, by using an additional pulley, the diameter where the rope unrolls at the start of the exercise, hence partly changing the resistance of the exercise.
  • the aim of the present invention is therefore to eliminate the aforementioned drawbacks, in particular to eliminate the need to vary the resistance by directly intervening on the flywheel or using a conical shaft to vary the resistance of the exercise.
  • the invention achieves this aim by using a device that allows the variance of the dimensions of the flywheel shaft while maintaining a cylindrical shape.
  • the advantage obtained from the present invention is essentially that it allows the resistance of the exercise to be changed without intervening on the flywheel in any way and by keeping the shaft cylindrical and not conical; therefore, the needs of different users can be met with a single flywheel, for instance for athletes who need to perform high-resistance exercises and for patients in the rehabilitation phase who can only withstand a lower resistance. Additionally, changing resistance becomes faster and helps the user to save time during training.
  • the present invention concerns an isoinertial training apparatus, comprising a flywheel (20) provided with a shaft (22), a flexible traction member (2) connected to the same shaft (22), on which it can be wound and unwound, and a supporting structure (1), which is fitted with a hole (3b) through which the traction member (2) and a user-supporting platform (3a) can pass, and a device (10) to vary the effective diameter of the shaft (22), comprising at least one sleeve (4) slidable along the shaft (22) of the traction member (2) and of the flywheel (20).
  • the unwinding of the traction member (2) sets the flywheel (20) in motion, imparting on it a velocity (and, therefore, a resistance) that depends not only on the dimensions and mass of the flywheel itself, but also on the dimensions of the shaft (22); indeed, the greater the radius of the shaft (22), the lower the resistance offered by the flywheel (20).
  • Each sleeve (4) has a slot (4a) into which the traction member (2) is made to travel and, preferably, although not indispensably, means for fastening (4b) to an end-stop plate (22b) built into the shaft (22) of the traction member (2) to ensure that the sleeve (4) rotates integrally with this shaft (22).
  • the fastening means (4b) comprise shaped grooves complementing radial rods (22c) fastened to the end-stop plate (22b).
