To be capable of run fast you have to have what is known as an excellent running economy. This is defined as being as just how much energy is required to run at a certain speed when running. Any energy which is sacrificed on unneeded actions or movements is a poor running economy. Some of these may be things like an ungainly or too much arm swing or a poor running technique. If those failures of the way a runner runs can be enhanced, then more energy will be available for running faster and much more economically. This really is such an very important topic for those serious about the subject of running science that an episode of the livestream, PodChatLive was devoted to the main topic of running economy. running economy is a regular training show for podiatry practitioners that goes live on Facebook and is later added to YouTube along with the audio edition is made available as a podcast. The show is hosted by Ian Griffths from Cngland and Craig Payne from Australia.
In the live on PodChatLive they had on as a guest to discuss running economy, Dr Izzy Moore coming from the Cardiff Metropolitan University in the UK. In the live they discussed how the runner self-optimises by itself for running. The issues of if we should modify the way we run for performance improvement and if these modifications are worth it. There was also the topic of the impacts on overall performance could be if we are modifying running technique in the context of injuries. Additionally, they spoke of running footwear and the affect that they may well have on running economy. Even the situation of the barefoot running gimmick was mentioned. Dr Moore is a Lecturer in Sport and Exercise Medicine, focusing in lower limb biomechanics at Cardiff Metropolitan University in Wales, UK. Izzy's research interests are in how and why we move the way we do. Her primary research presently is focused on running gait retraining for efficiency as well as injury reduction. She is also guiding various corporations on injury reduction and management methods.
