BJSM Podcast

Jeremy Lewis, consultant physiotherapist and visiting professor of Physiotherapy at Chelsea and Westminister NHS Foundation Trust, talks to Prof Jill Cook about management of rotator cuff tendinopathy. They cover the role of the subacromial bursa in the condition, new treatment paradigms, hopes for future developments. Bursa: 3.40 Changing treatment paradigms: 6.00 Future developments: 13.30

In the second part of this two-part podcast, Ross Tucker, one of the authors on The Science of Sport (http://www.sportsscientists.com/) explains how a understanding what limits performance can help an athlete achieve their best. He covers the use of GPS data and other measures of training volume, the difficulty that massive volumes of data creates, and how teams can use advanced sport science programs to gain a competitive advantage. He illuminates recent discoveries that ‘central’ processes - ‘the central governor’ - regulate performance; this contrasts with older views that suggested anaerobiosis (lack of oxygen) in skeletal muscle limited performance.

In the first part of this two-part podcast, Dr Ross Tucker, one of the authors of the hugely popular blog - The Science of Sport (http://www.sportsscientists.com/) - talks about what makes an Olympic champion. Dr Tucker assesses the role of genetics, training and the validity of the ‘10,000 hour’ concept. He rationally, and with evidence, discusses the eligibility of Oscar Pistorius and Caster Semenya in the Olympics. Dr Tucker is an exercise physiologist, conditioning coach, and team coach. He is based at the University of Cape Town in the Exercise Science and Sports Medicine Department and the Sports Science Institute of South Africa.

Sudden cardiac death in footballers has been headline news, so how should those involved in the sport be looking out for players? FIFA’s chief medical officer Jiri Dvorak explains what the organisation is doing, and Bolton Wanderers’ club doctor Jonathan Tobin gives us a pitch-side view. BJSM editor Karim Khan asks the questions. 0.45 FIFA’s pre-competition medical assessment 3.53 Organisation pitch-side 5.32 Researching the aetiology of sudden cardiac death – FIFA’s Medical and Research Centre 6.40 Putting plans in place 10.09 Getting the message and resources out worldwide 12.16 What to do if you want your club to be more prepared for cardiac events 15.27 Checklists for all involved 17.18 Automatic external defibrillators See also: FIFA’s Medical and Research Centre http://bit.ly/PDKLt5 Jon Drezner and the 2012 sudden cardiac death update: two new key messages http://bit.ly/M5Tjan

Per Holmich, head of the Arthroscopic Centre at Amager University Hospital, has been working for many years on overuse problems especially hamstring, groin and hip problems focusing on exercise treatment and hip arthroscopy. In this podcast he talks to Karim Khan about groin injuries, what to watch out for in diagnosis, and how to treat.

Karim Khan talks to Andy Murray, Scotland’s official Physical Activity Champion. After completing a gruelling 2659 mile run from John O’Grotes in Scotland to the Sahara Desert, Andy is now working to promote physical activity in the rest of the population. He talks about the programmes that the Scottish government is putting in place to improve the health of the nation through exercise.

Professor Jon Drezner emphasises the need for careful planning and practice of emergency protocols in the sports medicine setting. He also shares the new criteria for ECG screening - these lead to a much lower false positive rate than was previously reported. He makes a compelling case to include a resting 12-lead ECG in the periodic health examination of athletes. In this podcast he previews the international collaboration to improve the criteria for interpreting ECGs in athletes. These ‘Seattle criteria’ will be shared for free world-wide via BMJ Learning though sponsorship by numerous stakeholders including FIFA, AMSSM, PACES and ESC. 0.47 Has there been an increase in the rate of sudden cardiac death in sportspeople aged over 35 years? 1.42 What can clinicians do to minimize the risk of sudden cardiac death? 5.14 Screening and periodic health examination 8.56 Efforts to increase the accuracy of ECG interpretation - the Seattle meeting 21.04 AMSSM - a great member society for primary care physicians 23.33 Summary See also: BJSM blog: ECG Summit in Seattle: Successes and Next Steps http://bit.ly/wCELeS You can read how a two page tool with criteria for assisting interpreting ECGs in athletes led to improved accuracy in ECG reading by sports medicine attendings, primary care attending and primary care residents http://bit.ly/12EJwz4 Jon’s previous BJSM podcast: Preventing sudden cardiac death with Jon Drezner http://bit.ly/occXQj The two page tool http://bit.ly/14LIF2Y Recommendations for interpretation of 12-lead electrocardiogram in the athlete http://bit.ly/Y1iUbO Detailed criteria for the interpretation of the electrocardiogram in young athletes http://bit.ly/ZJOMgi

Babette Pluim (BJSM deputy editor) talks to Ann Cools (professor in the Department of Rehabilitation Sciences and Physiotherapy, Ghent University, Belgium) about her varied research into shoulder injuries. 0.21 Scapular involvement in shoulder pain in overhead athletes 1.32 Treatment strategy of internal impingement in the overhead athlete 3.11 The Scapular Summit 2012 4.49 Eccentric training for shoulder injuries 6.27 Scapula Dyskinesis 8.56 Age related change in the shoulder in tennis players 11.15 Adaptations in scapular movement, subacromial space, and range of movement and strength in elite handball players 15.47 The European Society for Shoulder and Elbow Rehabilitation (EUSSER) See also: Descriptive profile of scapulothoracic position, strength and flexibility variables in adolescent elite tennis players http://bit.ly/ZJOhTI Rehabilitation of shoulder impingement syndrome and rotator cuff injuries: an evidence-based review http://bit.ly/ZJOkyC Screening the athlete’s shoulder for impingement symptoms: a clinical reasoning algorithm for early detection of shoulder pathology http://bit.ly/15DCSMn Internal impingement in the tennis player: rehabilitation guidelines http://bit.ly/Y1iEtt Evaluation of isokinetic force production and associated muscle activity in the scapular rotators during a protraction-retraction movement in overhead athletes with impingement symptoms http://bit.ly/129KBxq EUSSER www.eusser.org

Babette Pluim (BJSM’s deputy editor) talks to Alan Vernec of the World Anti-Doping Agency (WADA). They discuss the work of the organisation and the new posibilities blood passports are offering doping detection.

Karim Khan talks to Steven Blair, professor at the Arnold School of Public Health, South Carolina. Professor Blair discusses the wealth of evidence he’s built up on the benefits of exercise, why physical inactivity is a bigger problem than obesity, and how much and of what we should all be doing. 0.51 Why physical inactivity is a greater health problem than obesity 3.20 Why physical inactivity is an important factor in causing the obesity epidemic 6.18 How the World Health Organisation is waking up to the fact physical inactivity is a major health problem 8.47 The impact of genetic makeup on the benefits gained from physical activity 10.44 The benefits of physical activity in those over 60 11.52 How much and of what sort of exercise should we be doing to get the benefits?
