  • The lack of clinical research on PRP
    Lars Engebretsen

    I fully agree with the comment from Dr Creaney regarding PRP. Unfortunately, there is little sound clinical science supporting the use at the moment. The design of studies published so far has been far from perfect. The studies with poor design have tended to produce good results, whereas the RCTs with proper design have shown less of an effect. Another challenge is the multitude of unknown clinical variables such as amou...

  • PRP within the wider context of regenerative medicine
    Leon Creaney

    Dear Sir,

    I congratulate the IOC Consensus panel on having produced as clear a summary of the current understanding of the basic and clinical science relating to PRP as the body of published literature allows. While there was initially great hope in Sport Medicine circles that PRP would become the magic bullet for injuries, recent trials such as de Vos [1], have failed to provide that conclusive evidence so de...

    Dear Editor,

    We read with interest the recent statement released by BASEM on 26th November 2010 which criticises the way physical education (PE) is being taught in the United Kingdom. Previous authors suggest that...

  • Response to Ian Shrier
    Robert D. Herbert

    We agree with Ian Shrier that the finding of an effect of stretching on risk of muscle, ligament and tendon injuries should be interpreted with caution. That is why we wrote "The finding of an effect of stretching on muscle, ligament and tendon injury risk needs to be considered cautiously because muscle, ligament and tendon injury risk was a secondary outcome, and there was no evidence of an effect of stretching on the p...

  • Re: Stretching before and after exercise
    Ian Shrier


    I recently read the article Jamtvedt et al on whether pre and post stretching prevents injury 1 with interest. I commend the authors for their well-conducted study and would like to comment on two particular issues.

    First, the authors correctly point out that there was no difference in the primary outcome of all injuries, and that the analysis showing an absolute 22% reduction in muscle, ligament a...

  • Are we ready for GGPAQ?
    Natasha S Jones

    In response to the editorial- Physical activity in the UK: a unique crossroad.Br J Sports Med 2010 vol44 no 13

    I was delighted to read Dr Weilers editorial which eloquently presents many of the issues currently faced in exercise medicine. It is so important to debate this subject-particularly as we are in a unique position in the U.K to effect permanent change. I was interested in Dr Weilers' view that the intro...

  • The challenge of quality physical education
    Richard Larouche

    An article entitled "The challenge of low physical activity during the school day: at recess, lunch and in physical education" was recently published in the British Journal of Sport Medicine.[1] Briefly, Nettlefold and colleagues used uniaxial accelerometers (Actigraph GT1M) to estimate the level of physical activity (PA) over the school day in Canadian children aged 8-11 years. One of their most striking findings was th...

  • Are we genetically literate enough for gender verification in Sport?
    Ambroise Wonkam
    Dear Editor

    In the midst of the genetic/genomic medicine revolution, the Caster's controversy illustrates how human society is lacking in its ability to deal with Disorders of Sex Development (DSD) at either a social, competitive, legal or ethical level. Political fractionalization, by way of "protecting human rights" added fuel to the fire rather than defusing the situation. "We can't afford any mistakes, particularly as we...

  • Modulation of heart rate variability by cold water immersion
    Jamie Stanley
    Letter to the Editors,

    We read with interest the recent review by Bleakley and Davison (BJSM vol 44: 179-187)[1], which described the physiological and biochemical responses to cold water immersion (CWI) after exercise. The authors examined some of the acute cardiovascular responses that occur with CWI, such as changes in heart rate, blood pressure and cerebral blood flow. We noted, however, that they did not address the effec...

  • Injuries in Minor Hockey-Study by Researchers from the University of Buffalo
    Emile J. Therien

    A study recently published in the British Journal of Sports Medicine suggests that accidents are more commonly to blame for on-ice amateur- hockey injuries than bodychecking. The findings were based on a five-year study of 3,000 boys aged four to 18 in a youth hockey program in Burlington, Ontario. The study, conducted by researchers from the University of Buffalo, found that 66 per cent of overall injuries were the resul...
