Should the heel be on the ground while running?
There is no doubt that running has become a social trend. More and more urban people are rushing to run together. You can see more and more running figures anywhere in the morning, evening, roads, and countryside. Domestic marathon events and cross-country races have also suddenly emerged like bamboo shoots.
Today we come to talk about running poses. Many people have such a problem when they are just running. Should they run after the ground? There is no absolute answer to this question. The following is a brief analysis for you.
The disadvantage of the heel
1. Dr. Daniel Lieberman and his team at Harvard University's Skeletal Biology Laboratory used mechanical imaging to analyze the difference between the forefoot and the heel. The experiment showed that the impact of the forefoot on the joint can be reduced by 50%. In addition, the doctor also pointed out from the point of view of biological evolution that barefoot running is healthier.
2. When the heel is in contact with the ground, the ankle joint is at the dorsiflexion position. At this time, the ankle joint is in a locked state. The poor ankle joint cushioning tends to cause anterior tibial pain, tibial fatigue damage, and Achilles tendinopathy.
3, the heel is easy to cause brake braking, will reduce the forward speed inertia.
4, from the time the feet touch the ground, the heel contact with the ground from the heel to the foot from the outside to the front foot, the longer the contact time, the slower the support foot conversion speed, then the support foot conversion time will be slow, so difficult Maintain high frequencies.
The advantage of heel strike
1, from the analysis of the ease of implementation of the action, the heel action can be easily completed, does not require any learning that can grasp, and the front foot movement is a technical action, it takes a lot of time to exercise.
2. The forefoot has a high requirement for the muscular endurance of the calf muscles, and the requirement for the muscular endurance of the heel on the ground is relatively low.
Ground posture suggestion
If you want to run fitness without running big, pay attention to your running posture to reduce the probability of joint damage.
If you are running a lot every month, marathon several times a year, want to refresh your PB and hope that you can run longer, it is advisable to take time to learn the technology of the forefoot.
