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.

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.

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.

In a discussion around the paper entitled "Athletic groin pain: a systematic review and meta-analysis of surgical versus physical therapy rehabilitation outcomes " which features in my Research Review 107. I am delighted to talk with Enda King on the background behind his paper published in the British Journal of Sports Medicine in 2015.
We talk about the diagnosis of Athletic groin pain, the recent Doha Consensus statement and underlying anatomical diagnoses. We divide the literature in surgical versus rehabilitation for each of these diagnosis and the surprising lack of evidence in some of them.
We focus on some emerging work on return to play time and rate comparing pubic surgical and rehabilitation approaches and discuss the literature regarding interventions to date.
We expand to debate the direction of future research, and lack of true multi directional return to play tests and Enda highlights some work being carried out at the Sports Surgery Clinic using 3D Biomechanics of high speed movement.
Enda King is a Chartered Physiotherapist currently undertaking a PhD in Biomechanics at Roehampton University, London and is Head of Performance Rehabilitation at the Sports Surgery Clinic, Dublin.

I talk with Vern Gambetta on the pool deck in Portland, Oregon about strength and power training, periodisation and timing of dry land training for swimming. We cover 'go to' exercises, the role of multi chain single arm symmetry lifts, the need to prepare to swim, not swim to prepare and also touch on the performance benefits of rate of force development in starts and turns alongside the timing of training sessions.
A founding father of athletic development, movement skills and coaching of multi sport athletes for over 40 years he is the go to guy for me on coaching. I would describe Vern as the 'Coaches Coach'. A physical educationalist and teacher at heart he has been strength and conditioning coach for professional sports from baseball to soccer, swimming to track and field. Currently working with multiple cross code athletes and swim teams his view are always stimulating.
