 How does a ‘heart patient’ build a sports club? Patient empowerment for health. #378 | File Type: audio/mpeg | Duration: 25:17

Farooq Mohammed was a football fan who discovered that he has heart disease. In this BJSM podcast, we focus on the patient voice and hear from Farooq who shares his own lived experience with the disease and, importantly, how football became part of his rehabilitation. Farooq shows that by empowering patients to take control of their own health, rehabilitation can become a fun activity, not a boring ‘must do’ where the individual is counting down the minutes until it’s over. If you want to learn more about the “friendly group of ‘Heart Patients’ from #EastLondon” who make up Two Touch Athletic Football Club, connect with them on Twitter (@TwoTouchAFC) or Linked In (TwoTouchAthleticAFC). The conference that Farooq refers to was the 2019 Football is Medicine conference, University of Southern Denmark, Odense. It was led by Professor Peter Krustrup: http://ow.ly/7Xxn30oxFFR You can find another BJSM patient podcast here: http://ow.ly/rXis30oxFMJ Christina Le shares her lived experience of suffering an ACL injury in 2017.

 Physical Activity and Cancer, an update with Dr Rebecca Robinson. Episode #377 | File Type: audio/mpeg | Duration: 17:45

In this podcast Dr Katie Marino interviews Dr Rebecca Robinson about physical activity & cancer. Dr Robinson is a Sport and Exercise Medicine Consultant in Sheffield who has clinics at Weston Park Hospital in Sheffield working directly with cancer patients. During the podcast she gives a great insight into our current understanding of the use of physical activity in cancer patients. As Macmillan quote that by 2020 almost half the population will develop some form of cancer in their lifetime, it is important that we increase our understanding of how physical activity can be used to improve quality of life in this patient group.

 How many push-ups can you do? Assessing cardiovascular risk with Dr Alex Hutchinson PhD. #376 | File Type: audio/mpeg | Duration: 16:41

Drop and give us 20. On this week’s BJSM podcast, Dr Alex Hutchinson PhD (T:@sweatscience) joins BJSM’s Daniel Friedman (T: @ddfriedman) to make sense of all of the click-bait headlines and explore whether push-up prowess is the secret to long life. Alex writes Outside’s Sweat Science column, about the science of endurance and adventure. He started out as a Cambridge-trained physicist and long-distance runner on the Canadian national team. As a journalist, he earned a National Magazine Award for his energy reporting with Popular Mechanics, covered adventure travel for The New York Times, and wrote a training column for Runner’s World. His latest book, out in February 2018, is ENDURE: Mind, Body, and the Curiously Elastic Limits of Human Performance. He lives in Toronto, where he runs fast, climbs poorly, and gets outside as much as possible with his wife and daughters. In this 17-minute conversation, Alex discusses: · If push-ups can predict your likelihood of future cardiovascular events · What we can learn from functional tests that aim to assess different health outcomes · New data on the cardio vs weights debate Further reading: Yang J, Christophi CA, Farioli A, Baur DM, Moffatt S, Zollinger TW, Kales SN.

 Upper extremity issues in the adolescent overhead throwing athlete. Episode #373 | File Type: audio/mpeg | Duration: 30:21

What common injury patterns do adolescent overhead throwing athletes face? What are the current pitch count recommendations and evidence for their use? How can we best monitor and encourage compliance with these recommendations? Host Dr. Devin McFadden, MD is joined by Dr. Jason Zaremski to explore these topics and more on the AMSSM Sports Medcast. Dr. Zaremski is an assistant professor from the Division of Physical Medicine and Research, Department of Orthopaedics and Rehabilitation and Co-Medical Director of the Adolescent and High School Outreach Program at the University of Florida College of Medicine in Gainesville, Florida. He is also a past participant in the AMSSM International Travelling Fellowship program, having recently travelled to Scandinavia where he shared insights on the above topics and learned how the Scandinavians deal with similar injuries. In this 30 minute conversation Dr. Zaremski addressed the following topics: What are common injury patterns in adolescent overhead throwing athletes? What injury prevention strategies have been enacted and what is the evidence for their use? When to consider operative rather than conservative treatments.

 In the driver's seat with Formula One physio Kim Keedle. Episode #372 | File Type: audio/mpeg | Duration: 17:31

Breakneck speeds. Scorching heat. Extreme g-forces. Motor racing is one of the most challenging of all sports - not only for drivers themselves, but also for the teams that play an integral role in the performance of the driver and car. As the 2019 Formula One World Championship Season launches into action this weekend in Melbourne, F1 physiotherapist Kim Keedle takes a pit stop with BJSM’s Daniel Friedman (T: @ddfriedman) to share insights into the physically and mentally demanding world of motor racing. Kim graduated from Melbourne University in 2012 with a Bachelors of Physiotherapy, and completed a Masters in Strength & Conditioning at Edith Cowan University in 2016. He is currently working full time as a physiotherapist and high performance coach for the Haas F1 Team, based in Geneva. In this 17 minute conversation, Kim explains: · His pathway into F1 · The role of the physiotherapist within the broader F1 medical team · The physical and mental demands of F1 racing · The importance of neck and trunk strength for drivers · Cervical loading programs and conditioning during the off season Further reading: https://blogs.bmj.com/bjsm/2013/03/26/the-fast-and-the-furiousand-physiotherapy-training-for-extreme-g-force-loads-on-the-neck/ Contact Kim: kkeedle@gmail.com
