Coaching advice is commonly based on a theory of why specific actions work, or on facts of how certain actions work. Advice from some personal fitness coaches and trainers can be categorised into two classifications: evidence-based approach and theory-based approach. An example would be that a person who runs with ideal style, technique and form will be more effective and faster than a runner who does not have those. This challenges the trainer, personal fitness expert or runner to pursue their own running style. What is thought to be the ideal running style is arguable and may be based on incomplete information, subjective data and/or expert opinion.
There is increasing information on the subject of what good running should be like. The two of the most developed concepts are the Chi Running and the Pose Technique of Running. These programmes have training programmes on video, books and internet sites.
The Pose technique of running was formulated by Nicholas Romanov. The ideal pose is with the runner poised on his support. This technique is designed to prevent excessive joint strains. Athletes use this technique by landing on the midfoot, and with the use of hamstring muscles, they withdraw the foot from the ground. The technique is simple but it needs the athlete’s dedication in order to train him to perfect the pose running technique. On the other hand, the Chi technique is based on the runner having the correct posture, which is described in a book as a slight forward bend in the ankle joint and with the legs calm, and the foot picked up from the ground.
Both Chi Running and the Pose Technique aim to increase running effectiveness and avoid injury.
