Waist and abdomen strength also has a fashionable title, which is core strength. In fact, because the waist and abdomen is close to the center of our body, it is called core. Therefore, core is only a positional term here and does not represent the degree of importance.
1、 The waist and abdomen can’t provide running power, but why do runners need to strengthen their waist and abdomen.
Indeed, the direct driving force of running mainly comes from the lower limbs, which push the human body forward by pedaling on the ground. But if you think you can run fast as long as you practice your legs, you are very wrong.
Almost all sports need enough lumbar and abdominal strength. Strong lumbar and abdominal muscles play a stable and supporting role in body posture and special movements. The technical movements of any sport can not be completed by a single muscle. It must mobilize many muscle groups to do work in coordination. In this process, psoas and abdominal muscles play the role of stabilizing the center of gravity and conducting strength. At the same time, they are also the main link of overall force, and play a pivotal role in connecting the upper and lower limbs.
For running, according to the principle of physics that the rotational torque remains constant in a closed individual, when we step out of the left foot, the trunk will rotate to the right with the left foot, which must be accompanied by the forward swing of the right hand to balance the rotational torque to the right. In this way, the upper and lower limbs can cooperate subtly to maintain balance, Then in this process, the strong lumbar and abdominal muscles play an important role in supporting the upper and lower limbs and connecting the preceding and the following.
Whether it is a strong leg kick and swing, or a stable arm swing of the upper limb, it needs to take the lumbar and abdominal muscles as the support point for the strength of the upper and lower limbs. Therefore, we can see that people with good waist and abdomen strength start running. Although the action frequency of upper limb swing arm and lower limb swing leg is very high, the trunk remains stable all the time. When people with insufficient core strength start running, their trunk twists disorderly and their pelvis swings up and down. In this way, the strength generated by the upper and lower limbs is unnecessarily consumed by the soft and weak core, which greatly reduces the running efficiency.
