Description

An aerobics jumping training method that improves safety

Technical field

The present invention relates to the field of aerobics training equipment, and in particular to an aerobics jumping training method that improves safety.

Background technique

Aerobics is a popular and popular sport that integrates group exercises, dance, music, fitness and entertainment. Aerobics incorporates a large number of movements of the upper and lower limbs, trunk, head, neck and feet from disco dance, jazz dance and break dancing, especially hip movements, which adds vitality to aerobics and is also beneficial to reducing buttocks and abdominal fat. The accumulation of weights is conducive to improving the coordination and flexibility of movements. In competitive aerobics, there will be many jumping movements, such as 900°, 720° rotor rotation, 720° free fall to the ground, push-up, and rotation. 180° into push-ups and other movements.

The 180° turn into a push-up action is when the performer jumps up and turns 180 degrees on the spot, and then puts the palms of the hands on the ground to support the whole body into a push-up state. This action requires the performer to have a graceful posture in the air, and also requires the performer to land on the ground. When doing this, use your hands to support your whole body.

In traditional aerobics training devices, slings are used to tie the trainer's waist to prevent the trainer's waist from hitting the ground and being damaged when landing. Although the use of a sling can effectively reduce the waist damage of the trainer, it will not cause any damage to the trainer's waist during the entire 180° turn. In the push-up movement, when the trainer completes the final push-up movement, it is an integrated movement and needs to maintain a certain shape until the end. The traditional sling movement will cause the trainer to flatten his body and press down during the push-up movement. , supports the trainer's waist, causing the trainer's posture to deform, affecting the quality of training. The traditional method of protecting the trainer's hands from a large impact is to put protective pads under the trainer's feet. Traditional protective pads have a certain degree of elasticity. It can reduce the impact force on the arms and palms of the training personnel when they land, but it still has shortcomings. During the entire 180° turn into a push-up action, the final push-up requires the performer to keep moving downward for a certain distance in a push-up posture. When moving downward for a certain distance, the arms and palms will be subject to great impact. Traditional protective pads cannot effectively dissipate these impact forces, and may still cause injuries to the arms and palms of trainers. For this reason, we propose An aerobics jump training method that improves safety.

A kind of aerobics jumping training method that improves safety according to claim 7, characterized in that: the triggering mechanism (9) includes a triggering ejector rod (91), a movable insertion rod (92), a return spring ( 93) and the trigger slider (94), the upper end of the trigger ejector pin (91) is movablely connected with a movable insertion rod (92), and the outer surface of the movable insertion rod (92) is sleeved with a return spring (93), so A trigger slider (94) is fixedly connected to the lower end of the trigger ejector (91). The trigger slider (94) is slidingly connected to the cavity wall of the limiting chute (8). The trigger mechanism (9) passes through the trigger slider. (94) is movably installed in the inner cavity of the limiting chute (8). 9. An aerobics jumping training method for improving safety according to claim 8, characterized in that: an annular groove (911) is provided on the outer surface of the trigger ejector rod (91), and the annular groove There is a trigger ring (912) movable inside the trigger ring (911), and a set of first contact limiters (913) and second contact limiters (914) are respectively fixedly installed on the upper and lower ends of the trigger ring (912). ), and the left and right sides of the trigger ring (912) are fixedly connected to the inner wall of the limiting chute (8). The first contact limiter (913) and the second contact limiter (914) are respectively connected with the winding motor. (10) Electrical connection. 10. An aerobics jumping training method for improving safety according to claim 1, characterized in that it specifically includes the following steps: S1. First adjust the bolt (612) and the adjustment threaded hole (54) on the support rod (5) to adjust the position of the entire tightening mechanism (6) on the support rod (5) so that the rope (62) is in contact with the training The personnel maintains a suitable position. At the beginning, the first contact limiter (913) is triggered by the top wall of the annular groove (911), keeping the winding motor (10) closed, and the training personnel ties the waist cuff (66) to own waist; S2. The trainer leans down and sticks to the bottom plate (1), pulls the rope (62) through the waist, and lets the rope (62) be pulled out of the rewinding wheel (61). When his body is about to contact the bottom plate (1) When in contact, let other trainers adjust the position of the limit lock (64) on the rope (62) so that the distance between the contact switch (641) on the limit lock (64) and the lower part of the guide tube (63) is elastic. twice the length of the rope (65), the training personnel stand up and keep the rewinding motor (10) on. The rewinding motor (10) does not rotate at this time. The training personnel stand on the bottom plate (1) and practice turning in the air. 180% push-up action; S3. The trainer performs a 180 degree turn into a push-up action. When the hands fall to the ground, keep both hands on the buffer plate (73) on the buffer mechanism (7). When the trainer presses his hands on the buffer plate (73) , the buffer plate (73) is squeezed, and the buffer plate (73) is affected by the elastic force of the buffer spring (75) and the buoyancy of the buffer water (76), providing a reverse force to buffer the squeezing force on the training personnel's heads and slowing down the release. The force exerted on the trainer's arm by pressing down on the body part; S4. When the buffer plate (73) squeezes the buffer water (76) in the buffer cavity (72), the buffer water (76) flows into the limiter in the second vertical plate (4) along the conductive pipe (721). In the chute (8), the buffer water (76) entering the limit chute (8) pushes the trigger slider (94) in the trigger mechanism (9) to move upward. The upward moving trigger slider (94) causes the trigger top to move upward. The rod (91) moves upward, and the trigger ring (912) is fixedly connected to the inner cavity of the limiting chute (8), so that the bottom groove wall of the annular groove (911) triggers the second contact limiter (914), and the second The contact limiter (914) is triggered and sends a signal to the rewinding motor (10). The output end of the rewinding motor (10) works and drives the supporting rod (5) to rotate, thereby causing the rewinding wheel (61) to rotate. The rewinding wheel (61) rewinds the rope (62) in the rewinding wheel (61), so that the rope (62) is tightened and straightened, and the tightened rope (62) cooperates with the elastic rope (65) to pull The waist cuff (66) pulls the trainer's waist to prevent the trainer's waist from hitting the base plate (1). When the contact switch (641) is triggered, the contact switch (641) turns off the winding motor (10), so that The winding wheel (61) no longer winds up the rope (62); S5. When the training personnel leaves the buffer plate (73) with both heads, the buffer plate (73) no longer receives squeezing force, and the buffer plate (73) resets under the reverse force of the buffer spring (75) and the buffer water (76). , so that the buffer water (76) in the limit chute (8) is sucked back into the buffer chamber (72), and the trigger ejector (91) moves downward under the action of its own gravity and the force of the return spring (93). movement, allowing the top groove wall of the annular groove (911) to trigger the first contact limiter (913) again, and the first contact limiter (913) sends a signal to the rewinding motor (10) to keep the rewinding motor (10) )Disabled.
