When standing, fatigue continuously builds up in the leg muscles.
When we stand upright, the lower part of the thighbone remains on the upper part of the calf bone, which forms an inclined plane of about 12 degrees. As you support your thighs and upper body on this unstable surface, the muscles involved must remain tense.
However, if the calf bone is tilted forward by about 12 degrees so that the lower face of thighbone is placed on the flat upper surface of the calfbone, the fatigue of the entire leg, including the knee, is reduced compared to standing upright. The reason why you unconsciously lean on one foot is because fatigue accumulates a lot when you stand upright.
Standing state = continuous low-intensity tension state, Walking state = state in which tension and relaxation are alternately repeated
When walking, the muscles on the left and right sides of the body are in a state of tension and relaxation alternately, so the muscles of the legs and upper body are repeatedly given a relaxed state for about 0.5 to 1 second, even though the load on the upper body acts more heavily than when standing. In this short but relaxed state, the muscles can rest.
Why standing is harder than walking?
For the two reasons mentioned above, standing generally causes more fatigue than walking. However, if you walk a lot more than you normally do, fatigue can build up a lot.
Why walking a lot is good for your health?
The reason why walking a lot is good for health is because of the above two reasons. To increase the effect of walking, it is better to walk with a slightly upward gaze, as shown in the picture on the far right above. In the state of upward gaze, the body parts where the muscles are constantly tensed is completely disappearing. When looking straight ahead or looking down, some muscles related to the neck and back are constantly in a tense state. The continuous state of muscle tension leads to the accumulation of stress substances and means that blood circulation is not being performed smoothly.
