Many of us have had a hamstring twinge at one time or another, you know, that big muscle group at the back of the thigh. Well sportspeople are constantly injuring that muscle group at great cost to themselves and the team. David Opar and his team research, collaborate and coordinate the new wave of inquiry into hamstring injury, rehabilitation and management.

Injured athletes like to recover and return to play as quickly as possible, and we need to balance return to play against impaired strength, performance and risk of reinjury. Initial injury rehabilitation often commences with isometric exercises, progressing into concentric/eccentric style exercises when isometric tests are pain-free. Finally high load eccentric exercises such as the Nordic hamstring are introduced for their positive effects of increased strength, fascicle length and reduced injury risk. High level and eccentric exercises are often avoided in the early stages of rehab, for fear of aggravating the injury. What if we could commence higher-level and eccentric exercises safely at an earlier stage? Would this impair or accelerate your patients' recovery? In this podcast with Jack Hickey, currently completing a PhD with the QUT/ACU hamstring injury research group, we explore an accelerated hamstring injury rehabilitation program, and how this can be implemented with your patients. You will discover: The limitations of traditional rehabilitation What is the evidence for only using isometric exercises in the early stages of rehab Why eccentric exercises are commonly thought of as too high a load for initial rehab More modern rehabilitation programs for hamstring strain injuries, including the Askling (2013), Aspetar (2017) and Mendiguchia (2017) programs An accelerated rehab program, introducing higher-level and eccentric exercises at an early stage How often high-level exercises need to be performed Which exercises you can use with your hamstring injury patients How to know when to progress your patient's exercises When you can start your patient's rehabilitation When your patients can return to running How to progress your patience through a return to running program When your patients are suitable for return to sport Download this podcast and subscribe on iTunes   Links associated with this episode: Get your free access to Sports Injuries presentations with Dr Ebonie Rio, Jack Hickey, Dr Adam Weir, Dr Michael Rathleff, Jo Gibson and Prof Bill Vicenzino Jack Hickey David Pope on Twitter Clinical Edge on Facebook Have a free trial Clinical Edge membership ACU open access hamstring journal repository Dr David Opar on Twitter Dr Anthony Shield Dr Morgan Williams Dr Matthew Bourne Nicol van Dyk Rod Whiteley Nirav Maniar Ryan Timmins Dr Steve Duhig Sliding discs to use in hamstring slider exercises in your clinic - available in Australia.

Hamstring injuries are the most common injury in football and AFL, and we can help our patients strengthen their hamstrings while significantly reducing their risk of injury with the right exercise program. What are the best exercises to use to strengthen and lengthen the hamstrings, and to prevent hamstring injury? In this Physio Edge podcast with Dr David Opar, we discuss hamstring injury prevention, which athletes will benefit, which exercises to use, the most important aspects of each exercise and how to incorporate these with your athletes. You will discover: What does the latest research around hamstring exercises and injury reveal? Which players are most at risk of hamstring injury? How can we prevent hamstring injuries? How does hamstring muscle architecture adapt to training, and how does this relate to your exercise selection or prescription? How can we increase hamstring muscle fascicle length? How can we tailor our patients hamstring program based on whether they are preseason, in-season, uninjured or previously injured? Which exercises are important in hamstring rehabilitation and prehabilitation? How can you start and progress a hamstring injury prevention program? How quickly do patients lose their hamstring gains, and how much maintenance do they need to perform? What happens to hamstring muscle strength and flexibility following injury? What neuromuscular inhibition happens following hamstring injuries, and how can we address this in our rehab? There has been a lot of great research performed recently on hamstring injuries, and to share this and help you with your hamstring injury patients, we have invited Dr David Opar to present at the upcoming Sports Injuries virtual conference in December 2017.

Over the last 12 months, Nordics have become a key criterion and point of progression for most of our athletes. In today's episode, we go deep on why we love them,  - why they are better than a deadlift and RDL for brute eccentric hamstring strength  - the mistake we made regarding Corelfits  - why the Nordic isn't quite perfect - why sport doesn't serve the hamstring well  - how eccentrics affect the collagen and titan in your muscles  - and how you can start adding them in without being sore for a week Some resources: This video from David Opar should provide a great summary of all things hamstrings: https://www.youtube.com/watch?v=48MAhno35Lg David Opar and the hamstring injury research group have done a heap of work on the Nordic and its effect on injury risk (this link will take you to a heap of their academic papers which you can read for free) https://scholar.google.com.au/scholar?q=david+opar+hamstring&hl=en&as_sdt=0&as_vis=1&oi=scholart&sa=X&ved=0ahUKEwjXoPXP6rjSAhXDEpQKHefTBAkQgQMIFzAA Also the Nordbord website: https://valdperformance.com/ Fascicle length: http://www.jsams.org/article/S1440-2440(12)00580-4/abstract More on Titin (not Titan): http://jeb.biologists.org/content/217/16/2825.long And collagen content of muscles: http://jap.physiology.org/content/97/1/197.long (a small study but Jacob seems to be onto something)

In episode 73 of the Pacey Performance Podcast I am speaking with hamstring expert, David Opar. With an ever increasing interest in the prevention of hamstring injuries in sport due to their relative frequency, it was great to get the world leading expert to discuss the issue.

Podcast titles are limited to 100 characters; the ideal title would have been…”Working as a multidisciplinary team in elite sport – the role of physiotherapy, strength and conditioning teams, medical folks, soft tissue therapists, exercise rehabilitators etc.”. A leading elite team physiotherapist (Andrew Wallis, PT) and a head of sports science/conditioning (Darren Burgess, PhD) provide you the inside view from within two elite teams. And they have international experience before their current jobs. You'll hear WHO these teams include on the sports medicine payroll. Our hosts (Ebonie Rio, David Opar) ask whose head would be on the chopping block if there was a rash of hamstring strains after a vigorous pre-season training. Is one hamstring injury recurrence among 10 players worth 9 players coming back a week early? What about sending players to the funky treatment' clinician – flying for the miracle cure? Apologies for a bit of shuffling noise in Andrew's first two answers but it disappears. Well worth pushing through that distraction (we are working on trying to get sound quality like in Jack Chew's podcasts!). Confident you'll love this inside view!

Dr David Opar joins us for this BJSM podcast. David is a lecturer at the Australian Catholic University in Melbourne and one of the emerging voices in the field of hamstring strain injuries, having done work on the possible mechanism of injury as well as prospective studies aimed at better understanding eccentric strength as a risk factor for these injuries. His work also investigates the Nordic Hamstring Device, developed by the Queensland University of Technology Hamstring Group, looking into the potential of this device in prevention, treatment and rehabilitation of hamstring injuries. Nicol van Dyk, a physiotherapist in the Rehabilitation Department at Aspetar Sports Medicine & Orthopaedic Hospital in Qatar, leads the discussion around nordic hamstring exercises, the role of eccentric strength in hamstring strain injuries and the seeing the big picture in prevention and rehabilitation. With hamstring strain injuries continuing to receive much attention in the literature and mainstream media, David Opar elucidates some significant features of this common injury.
