Every time the body moves, the muscles of the torso are fixed in other parts of the body. The body of the trunk itself, that is, the muscles of the trunk part, consists of the abdominal muscles and the dorsal muscle. It is the upper part of the body and the lower part of the body. All the movements are based on it as an action. At the same time, it is also The center of the body's movement, the starting point of the body movement. People in the movement, if not properly applied to this part of the muscles, the action efficiency will be reduced, and may even be injured. If the muscles supporting the spine after a certain training, the torso's own power requirements higher. And if the practitioner lacks the preparation activity or the back pain and other diseases, then there may be difficult to maintain stability in the movement and other issues, because they do not have the ability to properly use these muscles to support the spine. It should be noted that: the backbone of the support and stability of the muscles, including some of the deep muscles and tissues, such as diaphragm, pelvis, femoral muscle, etc., there are some superficial large muscle group.
For the practitioner, the internal strength of the trunk exercises are different, the internal muscles of the trunk to produce strength and transferred to the trunk and the lower starting and ending points, but also strengthen the lumbar and pelvis. Therefore, the internal muscles of the trunk need to be properly trained, including for each piece of different muscles for different exercises. The fitness ball is the most versatile tool, and it provides a different way of selecting the trunk muscles.
Balance ability is to maintain the balance of the human body, the most basic skills to walk upright. The balance is dominated by the nervous system, and it gives the nervous system the physical position and the signals needed by the movement through the senses, especially the eyes, the ears and the inner body receptors.
Balanced training allows practitioners to maintain a balance of body and avoid injury. When the external stimulus gives a signal of nervous system balance, for example, when you climb the slope, or when walking when the foot empty, the body needs to quickly adjust to restore balance, so as not to fall. Compared to those who have never been physically trained, people who have had a balanced training experience will adjust their physical posture and recover the balance in a shorter period of time.
Fitness ball movement to maximize the improvement of the body posture and the body's ability to adjust. From the biomechanical point of view, the correct physical posture refers to the knee to relax, the pelvis to stay in the middle position, chest, shoulder after the income, the head to maintain the middle position. Many people because of long-term sedentary posture, resulting in physical strain to maintain the physical strain, trunk muscle is not strong enough to support the weight of the body; the same time, because the neuromuscular system can not properly maintain the body's correct posture, thus increasing the chance of injury. Fitness ball can exercise through the balance to improve the body posture, the difficulty increases, the body will be balanced by self-regulation. When the body lost the external support, through the adjustment of the spine to restore the body to the best balance position. Every move on the fitness ball depends on the feeling and consciousness of the body itself. Therefore, the practitioner should be encouraged to self-adjust, enhance the confidence, increase his balance, the more practice on the ball, the body's self The stronger the ability to control and improve the ability of the central nervous system response, help to help maintain the stability of the spine, to avoid injury.
Maintaining the center of gravity (centerline) is also important for Gym Ball. Usually we consider the activities of the back of the back, it will be combined with the pelvic study in the ball forward, rear, lateral movement, the pelvis also occurred in the tilt, "central" is relative, for example, in the spine no side Move the premise, it refers to the spine is not forward or backward direction of the shift and remain in the central position.
Safe and smooth transition, must pay attention to some factors: in the process of moving, when a leg or hand lift off the ground, you can guide the practitioner to move in small steps to maintain balance, at any time in practice must promote the spine in the middle Position, which is particularly important for the cervical spine, because when the body from the ball back to the seat, the head and neck in the trend of being pulled. When the legs lifted, they should be prompted to put their hands on the ball, increase stability. And then slowly lift the hand or on the side of the body, all the conversion should be relatively slow speed, in the control of the premise, in the movement, we must maintain the stability of the center of gravity to maintain the balance of the body.
