Injury prevention : What is the basis of our recommendations ?
80% of injuries are caused by mechanical overload from a change of habit . The best way to prevent injuries is the quantification of mechanical stress : the body adapt to mechanical stress . Footwear and biomechanics are only a small part of the puzzle . Sorry, french only !
Debate on injury prevention
Running Shoes : definition and state of knowledge
Pronation control technologies are ineffective. Absorption into the shoes do not reduce the stress on the backbone. Over the shoe is minimalist, the more stress on the knees, hips and back and reduces the stress on the Achilles tendon and the foot increases. It is the reverse with the maximalist shoe. No technology promoted by the companies did reduces injuries. We are in a market driven by marketing and non-clinical logical or scientific research. The research and development departments of the companies only offer the glitz. And most importantly, no clinical studies to justify the use of these technologies is proposed annually. I simplify the concept of the shoe by "how minimalist or maximalist the shoe is" (in relation to "how the shoe will influence the kinematics and running kinetics") and proposes a formula to quantify by specific characteristics (dimension CRT will be explained). Sorry, french only !
Discussion on Running Shoe
Running shoe foot injury prevention : What is the basis of our recommendations ?
In summary, minimalism for beginners and children and no change habits if you are suitable for shoe 're not hurt and do not wish performer .
I recommend that 90% of runners to run in minimalist shoes ( TRC score 70% and above). Retailers also moving walkers will all ranges and often sales of 50-50 %. Sorry, french only !
Debate: The running shoe she prevents injury ?
Running shoe and performance : What is the basis of our recommendations ?
The most powerful is that shoe is the lightest and minimally protects the foot from the environment to which it is not suitable. Train barefoot (or minimal) increase running economy over the long term. Sorry, french only !
Debate: What shoes to wear for a marathon ?
Running Biomechanics : What is the basis of our recommendations ?
I do not think the complex and detailed teachings . Interventions should be unconscious as possible (before voluntary reflex mechanism ). Different corrections are taught according to each response, to increase the impact moderating behavior and running efficiency. In order of frequency : the more minimalist shoe , cadence between 170 and 180, less noise, and only when necessary, specific interventions as a floor installation "mid Foot ", a more upright posture, etc. Sorry, french only !
Debate: Running biomechanics
Conclusion and end of the debate
For financial gain, companies recover fashionable concepts (like minimalism ) and / or get stuck in a mad dash to the technology " common sense " and " markettable " no real scientific validation as too costly. The marketing department has a lot more power and budget of the research and development section that is ultimately qu'orientée on materials.
Research does not support the prevention of injuries, but indirectly promoted as such. Actual changes in practice will the consumer informed and awakened by retailers and professionals (knowledge transfer) . Even those who will be detached from commercial influences and listen biased scientists not really studying the shoe. Sorry, french only !
