  • Fundamentally important information
    Per B Mahler

    Having taught medical students about the benefits of PA for the past 20 years and lived through WHO's 2002 World health day on PA, I had the belief that PA was now integrated and implemented in everyday practice. This nice little piece of research reminds us how difficult it is to change "routine" and how uncomfortable some of us feel when encouraging people to change their behaviour. Back to the drawing board...

  • Endurane Running and nutrition
    david lucas

    The article suggests that using fat as an energy source is how to fuel endurance events.

    Why is it that top marathons runners and the SKY/GB team don't do this but have a good balance of mainly carbohydrate and protein?

    Because using fat requires 3% more oxygen for the same amount of energy. Thus energy release is slower and it is why top athletes train specifically to perform glycogen depleted. If you...

  • Can evolution explain the jumper's knee paradox?
    Benjamin JF Dean

    Dear Editor

    I read the excellent study by Halland et al with great interest (1). This study adds further support to the link between higher jumping performance and the development of patellar tendinopathy, as the authors note in the discussion (2). The reasons for this link are unclear but it is worth considering evolutionary theory in any explanation. The 'pleiotropy' theory for the evolution of ageing prop...

  • "Role of Micronutrients, Antioxidants, Vitamin D and Virgin Olive Oil in Promoting Oral Health"
    Mahantayya V Math


    Dear Sir, We have read the nice article "Oral health and impact on performance of athletes participating in the London 2012 Olympic Games: a cross-sectional study" by Dr. Needleman and colleagues in your journal (Br J Sports Med2013;47: 1054-1058)(1). In developing countries, the prevalence of dental and periodontal diseases is very high as people...

  • Combined exercise and mobilisation techniques beneficial in treating lateral epicondylalgia
    Bill. Vicenzino

    As a topic worthy of updating, it is disappointing to note fundamental issues with both the methodology of this review as well as errors in reporting of studies, leading to a limited perspective of the role of exercise therapy and mobilisation techniques in treatment of epicondylalgia. There are two major issues that readers ought to be made aware of regarding this review.

    Issue 1: A major issue is the lack of...

  • Judo, the way of mutual welfare and benefits
    Emerson Franchini

    I would like to congratulate Dr. Nikos Malliaropoulos for the initiative to organize a Judo and Martial Arts issue in this prestigious journal1, a topic with increased number of publications in the last decades.2 However, despite the broad range of topics suggested in the initial call for papers1, only four papers (including the editorial) about judo/martial arts were published, which can be an indicative that the high -l...

  • Physical activity during pregnancy and the risk of gestational diabetes
    B Lauren

    My first question would be: what drug company funded this study? How many studies have there been over this last century showing exercise decreases and cures diabetes? Many.

    I find this type of "so-called" science incredibly dangerous and irresponsible as many women will make it an excuse to not exercise during pregnancy. Exercise during pregnancy most definitely not only reduces risk of diabetes but i have...

  • One off events are great but they don't deliver change
    Barry Horne

    The research into the physical activity response to the Sydney Olympics (and Paralympics) recognises that without a planned and sustainable investment in physical activity programmes over time there is no evidence of improvement.

    This should not surprise us for three reasons:

    1. People may be inspired by elite performance and feel the desire to increase their participation but this will not be sufficie...

  • Misinterpretation of Relative Risks and categorization of risk factors leads to wrong conclusions
    M Belen. Zapata Diomedi

    Dear Editor:

    We are writing to comment on the article by Wendy J Brown and colleagues published 29th May 2014 in this journal titled: "Comparing population attributable risks for heart disease across the adult lifespan in women". We discuss four issues with this article: use of population attributable risk (PAR) terminology, calculations, multiple category attributable fractions, and application of relative ris...

  • The reported comparison is incomplete
    J.S. Ross

    This article shows that activity ABOVE the official recommendation is associated with significantly less weight gain over 11 years than non- activity. It does not report weight gain findings for those AT the recommended level. Therefore the lead conclusion -- that officially recommended levels of activity may be insufficient to prevent weight gain -- may be true, but it is not supported by the evidence reported.
