Organised by La Trobe Sports and Exercise Medicine, the Running Science symposium in July saw a multidisciplinary line up of speakers discussing management of the running athlete. There was a wealth of information covered over the two days, and here’s a taste of what was offered!
Rich Willy @rwilly2003 kicked off proceedings with “Restoring load capacity in the injured runner”. Running participation has increased almost 300% since 1990 , with female participation seeing the greatest growth (25% of race finishers in 1990, 57% in 2013). Injuries in running are high with incidence in the literature varying from 19.4%-79.3% .
Management of the runner is a matter of balancing tissue tolerance & the ability to adapt (ie, strength, fitness, psychosocial factors, previous injury history, sleep) with biomechanical loading factors (ie, training loads, proximal & distal mechanisms) [3-7]. Often neglected factors in the treatment of the runner are psychosocial factors: patient education and an understanding of how important running is to the injured runner’s life are a must! [8-12]
The overarching theme throughout the two days was modifying load in the runner. We probably under load our runners in rehabilitation. Unlike what many think, running is not all about the gluteals! The soleus is the powerhouse for runners; it takes 6.5-8.0x body weight of force during running. Therefore during rehab, body weight exercises just don’t get it done when trying to improve achilles tendon stiffness and triceps surae capacity. Loads during running are MUCH higher than what bodyweight exercises can replicate. Heavy load resistance training is a must for runners and Willy concluded that we must load runners more to improve their overall load tolerance.
Next up was sports physician Dr Danielle Hope on: “Managing the Female Runner”. Dr Hope began by discussing energy availability and its relationship to bone health, general health and athletic performance. Dr Hope discussed Relative Energy Deficiency in Sport (RED-S) and causes of low energy availability focusing on its impact on menstrual dysfunction and bone health, with relative risk of stress fracture being 2-4 x greater in amenorrhoeic athletes. It is important to realize that low energy availability can be present with normal body weight, but this occurs at the expense of health. Also, covered in this presentation was: management of the uncomplicated pregnant runner, optimal loading for bone strength, urinary incontinence and breast pain/support during running.
Sports and Exercise physician, Dr Peter Brukner @PeterBrukner then discussed his current passion educating people about the perils of high carb low saturated fat diets, and the health benefits of adopting a ketogenic diet. He spoke of the unhealthy society that we live in with high rates of obesity, type 2 diabetes and many other ‘modern’ illnesses and talked about the lack of scientific basis of the dietary guidelines and food pyramid that we followed for over 40 years.
Dr Brukner also looked at the importance of diet in the running athlete. Some of his key points were:
- The jury is still out on carbs vs ketogenic on athletic performance
- It likely takes up to 6 months to adapt to a keto diet
- There is considerable individual variation with different diets
Dr Brukner’s key tips to a healthy diet:
- Basic diet should be low-carb, healthy fat, real food, avoiding sugar, processed foods & seed oils
- Give yourself plenty of time to adapt to the change of eating patterns
- You may find that you need to top up with some carbs before &/or during higher intensity activity
- Everyone is different, find what works for you!
With too many clinical pearls to fit into one blog, we just had to make this a two-part series!
In part 2, we discuss management of the older runner, achilles tendons, foot strength and running shoes PLUS a link to all the presentation slides! Stay tuned!
