Description

This apparatus is a combined action type strength training apparatus that comprehensively combines elliptical orbital pedaling movement, vertical movement of the seat position, forward and backward swing movement of the handle arm, and operation movement of the handle.

In recent years, an exercise program combining aerobic exercise and resistance training (muscular strength training) is considered effective as the basis for health promotion. Aerobic exercise includes walking, jogging, and bicycle exercise, and resistance training uses dumbbells, free weights, strength training machines, and the like. In addition, stretching exercises are recommended for the purposes of warming up and cooling down, health exercises, preventing or recovering from injury, and improving flexibility associated with these exercises.
As an apparatus for improving athletic ability in walking and jogging, there is an axle movement type bicycle ergometer (see Patent Document 1) for giving an ideal foot locus and load. This apparatus has a structure in which the pedal arm rotation center axis reciprocates horizontally.
Japanese Patent No. 3465044

The present invention includes all elements of aerobic exercise, resistance training, and stretching exercise in a single training machine, and aims to enhance the health promotion effect by performing multiple operations simultaneously. It is.

In the bicycle pedaling type training machine, the pedaling motion that draws an elliptical trajectory, the vertical reciprocating motion of the seat position, and the swinging motion of the handle arm are automatically performed, and the operation motion of the steering wheel is performed simultaneously. It is a training machine that can be performed.
Preferably, the pedaling motion for drawing the elliptical trajectory is performed by the elliptical trajectory pedaling device, and the vertical movement of the seat position is performed periodically and continuously in synchronization with the pedaling operation. Further, it is preferable that the swinging motion in which the handle arm approaches or moves away from the seat position is continuously and periodically performed, and the operation of the handle in the left-right rotation direction can be performed with a resistance load. .

The apparatus of the present invention is a training apparatus including elements of “aerobic exercise”, “muscular strength training”, and “stretch exercise” that can be exercised happily even by a person with low physical fitness, and is effective for health promotion. It is. Furthermore, by simultaneously performing complex body movements, it is possible to obtain a stimulating effect on the nervous system related to exercise.

In normal bicycle pedaling motion, the rotation center axis of the pedal arm is in a fixed position, and the pedal arm is structured to move circularly around the rotation center axis. The device of the present invention has a structure in which the rotation center axis of the pedal arm circulates along a pre-made elliptical orbit. The movement of the rotation center axis of the pedal arm moves around the elliptical orbit at a constant speed that can be adjusted with power, using power, and the trainer just sits on the seat and puts his foot on the pedal. Thus, pedaling motion of an elliptical orbit is possible. In addition, the pedal rotation speed can be increased by applying a certain force to the pedal.
In normal bicycle pedaling exercise, the pedal arm is a rotational motion that draws a circle, so the leg motion is limited to the range of motion that draws a circular locus, and the knee extension muscle group (quadriceps) that causes the pedal to rotate ) Is used as the main active muscle, with little involvement of other muscle groups. However, by making the trajectory of the pedal arm an ellipse, a range of motion equivalent to the stride of walking and running is added, and muscle groups involved in pedaling exercise include biceps femoris (hamstrings), gluteal muscle Increased involvement of muscle groups around the pelvis and hip joints. Also, the form of exercise is close to that of the muscle group that works during walking and running exercise.

The vertical movement of the seat position is configured to reciprocate up and down repeatedly for a predetermined moving distance by a power unit. Normal bicycle exercise is performed with the seat height fixed. In this case, the range of changes in the flexion and extension angles of the knee and hip joints is determined by one cycle of exercise, and the muscles work across the joint. The activity pattern (contraction and relaxation) is also a certain pattern.
In the apparatus of the present invention, the position of the seat continuously reciprocates up and down in accordance with the rotation of the pedal, so that the range of angle change of flexion and extension of the knee joint and the hip joint increases, and the muscles involved in the pedal rotation motion The group's activity is a form of exerting muscle strength at various joint angles, and the involvement of the abdominal and back muscle groups increases. That is, the reciprocating movement of the seat is repeated in order as time passes, in the case of pedaling for a bicycle with a low seat or pedaling for a bicycle with a high seat.

The swinging motion of the handle arm is performed continuously and periodically using a power unit, but according to the movement of the handle arm, the exercise posture of the trainee sitting on the seat and holding the handle is The bicycle periodically changes to a bicycle rowing posture in a posture that leans forward or in a vertical posture. When leaning forward, the waist and back muscles are stretched to produce a trunk stretching effect.
The shape of the handle is wider than the handle of a normal bicycle, and when the handle is moved to twist it to the right (clockwise direction) or left (counterclockwise direction), resistance may be applied by the exercise load device It has become. When the handle is moved in the direction of rotation, it is necessary to exert muscular strength spontaneously, so that a twisting movement effect of the trunk accompanying the rotation of the shoulder, the arm, and the handle occurs. By adding a spontaneous handle movement in accordance with the periodic movement of the legs and seats, the overall factors associated with the movement increase.
