Definitions

  • the invention relates to a sports device for muscle training with a lower part arranged on a frame, rotatably fixable with respect to the lower body of a training person, preferably designed as a seat part, and preferably fixable with respect to the torso of the training person by holding or pressing against a substantially vertical axis relative to the lower part Lower part and to the frame of at least one initial rotational position, which can be pivoted back and forth, on which acts a torque which is preferably adjustable in its strength and optionally adjustable in its direction.
  • the sports equipment is primarily intended for use in bodybuilding, fitness training and rehabilitation.
  • the aim of bodybuilding and fitness training is to give the human body a balanced figure by building all the muscles evenly. This is difficult to achieve solely through physical activity, since in most sports individual muscles or muscle groups are heavily stressed, but others are neglected, which leads to muscular imbalances.
  • a large number of sports equipment has therefore been developed especially for body building, in which repeated work against an externally adjustable load can be used to train and build up a specific muscle or group of muscles. Through the planned use of all of the devices, the muscle build-up can be controlled in a targeted manner throughout the body.
  • An important aspect in the design of such sports equipment is to specify or restrict the course of movement by the device itself in such a way that only the muscles provided work, but there is largely no contraction of other muscles or muscle parts.
  • the oblique muscle which is arranged on both sides above the hip bones and connects the hip bones with the ribs, can be built up by twisting the upper body and lower body against an adjustable torque or an adjustable force, but keeping them as immobile as possible.
  • sports equipment is known (US-A 4456245), the fixed seat part of which can be locked in several rotational positions left and right of a rest position is provided with support cushions for fixing the lower body.
  • An upper part provided with armrests and handles can be rotated from the rest position in both directions against a restoring force into an initial rotational position with respect to the seat part.
  • the stimulus When the stimulus then reaches the oblique muscle and this begins to work on contraction, it is already partially contracted on one side of the body and stretched on the opposite side of the body, so that it can no longer do the full work in the remaining section of the rotational movement. It therefore takes an unnecessarily long time to build up the oblique muscles. Since there is no pre-stretching up to half of the contraction, this muscle building takes place only to a limited extent or not at all. In addition, the transversospinal muscle systems in the lower thoracic and lumbar region are not contracted in this case and are therefore not developed. The load on the transversospinal muscle groups also decreases continuously from the beginning of the thoracic vertebrae to the end.
  • the upper part provided with handles and armrests is firmly connected to the device frame, while the seat part can be rotated against a resetting torque against the upper part and the frame.
  • the rotation of the seat part is initiated there in the area of the hip and thus in the lower area of the oblique muscles, but other muscles contract here as well.
  • the exerciser can subconsciously falsify the exercise by isometrically tensing the oblique muscles on both sides. When a muscle is contracted isometrically, it does not contract and therefore does little or no work to build muscle. Isometric training also permanently shortens the muscles, which leads to tension and imbalances in the body.
  • the upper body is not or only slightly rotated relative to the lower body and the rotational movement of the seat part relative to the upper part which is firmly connected to the frame takes place through an undesired contraction or Stretching the shoulder or upper arm muscles.
  • the transversospinal muscle groups are trained with such a device only in the lumbar region, while the portion of the transversospinal muscle system in the thoracic vertebra area is not subjected to any stress.
  • the invention is therefore based on the object to improve a sports device of the type mentioned in such a way that the oblique muscles can be optimally built up with the exclusion of other muscle parts and at the same time the transversospinal muscle system in the thoracic and lumbar vertebrae area can be evenly loaded.
  • the invention is based on the idea of achieving an isolated load on the oblique muscles and making an isometric tensioning of the same difficult or impossible, and on the other hand the transversospinal, by means of a lower part and upper part, which are difficult to counteract the restoring torque against the frame Equally load the muscle system in the thoracic and lumbar region and thus improve the stability and mobility of the spine.
  • the bottom part and the top part are expediently mechanically coupled to one another in their pivoting movement, for example by means of a rescue or gear wheel gear.
  • the coupling member is designed in such a way that it can transmit the torques in unchanged size or can increase or reduce them.
  • Those acting on the bottom and the top Torques can be changed independently of the angle of rotation or as a function of the angular position by appropriate design of the coupling member or of the organ exerting the torque. In a rest or entry position, no torques expediently act on the lower part and the upper part.
  • the upper part and lower part can be rotated about a common axis according to a preferred embodiment of the invention.
  • the upper part and the lower part can be arranged on two separate shafts rotatable about the common axis. If the top and bottom are supported downwards, one of the two shafts is expediently designed as a hollow shaft and rotatably supported on the other shaft and on the frame.
  • the shaft carrying the upper part can, however, also be suspended rotatably upward on the frame.
  • At least one auxiliary element which can be acted upon by a variable tractive force is arranged on the frame of the sports device and is connected to the upper part and / or the lower part, the one from the traction element Exerted force acts outside of the rest position of the lower or upper part eccentrically to their axis of rotation and thereby exerts a torque on the lower and / or upper part.

  • the turning shaft has at least three sprockets, while the shafts supporting the lower part or upper part are each provided with at least two sprockets.
  • Two sprockets of the reversing shaft can be connected to two corresponding sprockets on the shaft carrying the upper part by two oppositely interlaced open chain pieces.

  • the transversospinal muscle system that connects the vertebrae to each other and the vertebrae due to the respective fixation on spinous and transverse processes a torsional or rotational movement allows, loads and strengthens. Due to the introduction of the torque into both the upper body and the lower body, the transversospinal muscles on the twelve thoracic vertebrae and five lumbar vertebrae are evenly grasped and loaded. With different torque loads in the upper and lower body area, it is even possible to train the transversospinal muscles in the vicinity of certain muscles. This is particularly important in rehabilitation, since the exerciser can train selected selected transverse muscle groups in the absence of movement in order to improve the restricted mobility between the vertebrae concerned.

Abstract

Dans les appareils d'entraînement connus, le mouvement de rotation de la partie du siège ou de la partie supérieure n'est pas, ou n'est que partiellement introduit dans la zone du muscle oblique, de sorte qu'au lieu du muscle oblique, d'autres parties de muscle sont sollicitées à la contraction. L'appareil d'entraînement selon l'invention doit permettre de développer de façon optimale les muscles obliques, à l'exclusion des autres parties de muscle. A cet effet, la partie inférieure (10) et la partie supérieure (20) sont pivotables en va-et-vient en sens contraire, par rapport au bâti (30), les deux parties étant soumises à l'action de couples de rotation de sens contraire. Grâce à cette disposition, l'appareil d'entraînement convient principalement pour la musculation (''body-building''), l'entraînement pour la mise en forme (''fitness training'') et la rééducation.
