According to the walking rules, before swinging legs and feet follow the ground, the supporting legs must be straight, from one foot to two feet. Skills and requirements of race walking in physical fitness: the toes kicked after walking must not leave the ground, so as to be supported by both feet and not fly, which is the fundamental difference between walking and running. The speed of race walking depends on the step frequency and step size. Ordinary walking takes about 100 to 120 steps per minute, and race walking can take up to 180 to 200 steps. Excellent race walkers exceed 200 steps per minute. Generally, the walking stride is 70-80 cm, the walking stride can reach 90- 1 10 cm, and the stride of tall athletes is about 120 cm. Ordinary walking generally takes 0.50-0.55 seconds per step, and race walking only takes 0.27-0.32 seconds or less. So this increases the difficulty of alternating muscle tension and relaxation, which needs to be solved well in training.
Step size and step frequency are mutually restricted. Increasing step size will affect step frequency, and accelerating step frequency will also affect step size. Generally speaking, the step frequency should be increased under the premise of a certain step size. Excessive stride will increase the burden and tension of muscles, consume too much physical strength, easily cause fatigue, and is not conducive to the acceleration of pace frequency. When losing weight, many people will choose more common sports to lose weight, such as running. Although running has a good fat burning effect, few people can persist in running for longer every day. Running can not only burn calories and promote fat burning, but also improve vital capacity and physical fitness. However, running is not for everyone. For example, obese people (heavier weight) or patients with heart disease are not suitable for strenuous exercise.
What benefits can people get by walking 5 kilometers every day? A sport suitable for everyone is walking. Actually, we are no strangers to walking. We walk every day, but the length and steps of walking can also be used as our health indicators. Scientific research shows that we can walk 3000 steps every day and finish it in 30 minutes, which is an indicator of our health. However, few white-collar workers can achieve this walking goal. With the development of traffic, more and more people choose to go out for a ride, or they can meet various needs without going out. These habits make more and more people join the ranks of obesity. In fact, we can walk home after work, which is enough for physical exercise, thus increasing the number of walking steps.
