1. What is a foam shaft?
Foam shaft, also called yoga column, is generally light in weight and full of cushioning elasticity, which can help yoga practitioners complete various balancing actions. Especially after speed training and long-distance running, stiff legs will be relaxed immediately. Made of high purity EVA material. It can eliminate muscle tension, strengthen the strength and flexibility of core muscles, and achieve the balance of exercise. It is an indispensable equipment in modern yoga practice. Foam shaft can not only stretch muscles and tendons, but also decompose soft tissue adhesion and scar tissue. You can use your own weight and a cylindrical foam shaft to massage yourself and release myofascia, break the trigger point, relieve the tense fascia, and increase blood flow and soft tissue circulation.
Second, what is the principle of foam shaft?
There is a kind of tissue in the human body called fascia, which is the reticular connective tissue around our muscles and plays a role in supporting and protecting our muscles. Maybe we still can't understand whether there is a thin white film between raw meat and the meat we usually cook. Yes, that's fascia.
Fascia sometimes becomes stiff, such as after long-distance running, when muscle is injured or when there is no activity for a long time. In fact, the purpose of rolling the foam shaft is to relax the forbidden friction around the muscle and stretch the induration in the muscle, which is also called trigger point or myofascial adhesion. Therefore, when the trigger point is pressed by the foam roller, the pain will be aggravated, and in severe cases, the pain will be unbearable and the joint activity will be blocked. Autofascial relaxation technology mainly uses the principle of autoinhibition. When the foam shaft and the weight of the exerciser exert certain pressure on the muscle, the muscle tension increases, the Golgi Golgi tendinous apparatus that senses the change of muscle tension is activated, and the Golgi Golgi tendinous apparatus Huo Yuehong inhibits the muscle spindle that senses the change of muscle length, and finally reduces the degree of muscle contraction and relaxes the muscle.
The above is the knowledge about foam shaft. I hope it will be helpful for everyone to understand and use the foam shaft. For more information, please pay attention to Bian Xiao.
