I write a weekly 4 paper research review summary in sports medicine, science, and performance and you can subscribe at www.drandyfranklynmiller.com/review This week I summarise my thoughts on two papers that feature in the review, the first is an excellent meta analysis by Alex Dallaway et al "Age-related degeneration of the lumbar paravertebral muscles: Systematic review and three-level meta-regression" J.Exp. Gerontol. (2020) Online first The second investigates Exercise induced Asthma in swimmers and highlights issues with chlorine being in the pool environment but not in the testing "Diagnosis of Exercise-induced Bronchoconstriction in Swimmers: Context Matters. " Med. Sci. Sports Exerc. (2020) Pre View Hope you get something from it , and you can link to the written review and the papers by subscribing to the review

I am delighted to talk with Dr Enda King on his recent paper published this year in the American Journal of Sport Medicine "Factors Influencing Return to Play and Second Anterior Cruciate Ligament Injury Rates in Level 1 Athletes After Primary Anterior Cruciate Ligament Reconstruction: 2-Year Follow-up on 1432 Reconstructions at a Single Center." This podcast links to my weekly research review and a full review and link to the paper are in that via the link at the bottom of the page notes. Enda is a chartered physiotherapist and former Gaelic footballer, who is Head of Performance at the Sports Surgery clinic and has just completed his PhD in the Biomechanics of ACL Rehabilitation with Dr Siobhan Strike at University of Roehampton, London and is in current great demand for the rehabilitation of elite athletes around the world using 3D biomechanics as a tool to guide that process. We discuss the paper, including challenges behind the data set, where this might go, the differences in outcome in Return to play and why that might be and the differences in re-injury rate between bone patellar bone and Hamstring grafts.

I am delighted to talk with Dr Eanna Falvey and Enda King on the background behind our series of papers published in British Journal of Sports Medicine. Eanna is a Consultant in Sports and Exercise Medicine at the Sports Surgery Clinic, Dublin and Senior Lecturer in Sports Medicine at University College, Cork. A former Irish Amateur Heavyweight boxer he has been team doctor for the Irish Mens Rugby Team for over 6 years and two World Cups and as doctor to the British and Irish Lions. He has over 29 original publications, a PhD in Sports Medicine and is author of Clinical Sports Anatomy, McGraw Hill. Enda King is a chartered physiotherapist and former Gaelic footballer, who is Head of Performance at the Sports Surgery clinic and has just completed his PhD in the Biomechanics of ACL Rehabilitation with Dr Siobhan Strike at University of Roehampton, London and is in current great demand for the rehabilitation of elite athletes around the world using 3D biomechanics as a tool to guide that process In an evening discussion around the three papers published in the British Journal of Sports Medicine we start with anatomy, move to imaging and terminology and diagnostic sensitivity of tests, before moving onto the role of 3D biomechanics, how clusters have shaped our understanding and where they might go in the future before moving on to the success of the rehabilitation program and the various progression tools and use of HAGOS as a primary outcome measure.

I am delighted to talk with Dr Joe Warne on the background behind his paper published in Journal of Sports Sciences in a discussion around the paper entitled "Kinetic changes during a six-week minimal footwear and gait-retraining intervention in runners" which features in my next Research Review 153 Sign up here to receive a summary of the paper drandyfranklynmiller.com/review. We talk about running, running shoes, minimalist shoes, kinematics, impact, loading and running retraining all of which I will be speaking about this weekend at the New Zealand Physiotherapy Conference in Auckland.

I am delighted to talk with Assoc Prof Jacob Resch on the background behind his paper published in BMJ Open Sports and Exercise Medicine, in a discussion around the paper entitled "The sensitivity and specificity of clinical measures of sport concussion: three tests are better than one" which features in my next Research Review 132. Sign up here www.drandyfranklynmiller.com/review. The paper is Open access and can be accessed here http://bmjopensem.bmj.com/content/2/1/e000012.abstract We talk about the diagnosis of Concussion, the current state of neurocognitive function tests, the statistics behind them, and the basis for multiple tests and the improved sensitivity and specificity and also the future of concussion diagnosis. Dr. Jacob Resch completed his undergraduate degrees and Athletic Training and Health Promotions at South Dakota State University before traveling to study and work in London, England. After returning to the United States, Jacob completed his MS in Exercise and Sport Science at South Dakota State while working clinically for Orthopedic Institute in Sioux Falls, SD. Jacob then pursued his Ph.D. in Exercise Science at the University of Georgia investigating current and novel measures of sport concussion and became increasingly involved with the global efforts to expand the profession of athletic training. Following the completion of his doctorate, Jacob obtained an assistant professor position at the University of Texas at Arlington for four years where he taught within the Athletic Training Education Program and conducted research addressing sport concussion in middle school, high school, and collegiate athletes.He now serves as faculty of the University of Virginia Department of Kinesiology in the Fall of 2014 where he teaches in the Graduate Athletic Training Program and continues to investigate current and novel measures of concussion as part of the Brain Injury and Sport Concussion Institute. Jacob also serves as an active member of the National Athletic Trainers’ Association International Committee and the World Federation of Athletic Training and Therapy. The focus of Dr. Resch’s research is to investigate the measurement properties of current and novel measures of sport concussion in adult and adolescent athletes. Dr. Resch’s previous studies have addressed reliability and validity of computerized neurocognitive and balance measures. Dr. Resch is currently expanding upon his previous research with computerized neurocognitive and balance measures while investigating novel measures such as functional magnetic resonance imaging (fMRI), and other biomarkers.
