To be capable of run fast you need to have what is called an effective running economy. This can be thought as being as just how much energy is required to run at a particular speed when moving forward. Any energy that is burned on unneeded actions or movements may be a poor running economy. Some of these may be things like an ungainly or unnecessary arm swing or possibly a poor running technique. If those complications with the technique a runner runs can be improved upon, after that more energy will likely be obtainable for running faster and more economically. This is such an fundamental theme for anyone serious about the subject of running science that an episode of the live, PodChatLive was focused on the topic of running economy. PodChatLive is a weekly continuing education live for podiatrists which goes live on Facebook and is later added to YouTube along with the audio edition is made available as a podcast. It is hosted by Ian Griffths from the United Kingdom and Craig Payne from Melbourne, Australia.
In the show on running economy they had on as a guest to discuss running economy, Dr Izzy Moore out of the Cardiff Metropolitan University in the UK. In the show they talked about the way the runner self-optimises itself for running. The problems of whether we ought to alter the approach we take to run for performance gains and when those adjustments are worth it. There was also the problem of what effects on efficiency could be if we are altering running technique in the context of injury. Additionally, they discussed running shoes and the impact that they may possibly have on running economy. Even the dilemma of the barefoot running fad was spoken about. Dr Moore is a Lecturer in Sport and Exercise Medicine, focusing in lower limb biomechanics at Cardiff Metropolitan University in Wales, UK. Her research interests have been in why and how we move the way we do. Her major research currently concentrates on running gait retraining for performance and injury avoidance. She is also guiding a number of corporations on injury avoidance and management strategies.
