  • 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.

  • Incredulous
    Rand McClain

    I am a D.O. in the U.S. who practices Sports Med. However, even if I were a weekend athlete, I would/should know that tracking "weight" (often, BMI) is nearly useless and not that with which I am truly concerned. It's 2014, and the subject of "weight loss" has been written about and studied ad nauseum and the study leaders still track weight when - unless they are concerned about, e.g., knee pain 2/2 osteoarthritis - they...

  • Real life confounding factors
    Richard A. Mathews

    There appear to be a number of variables affecting the results of this study that have not been fully identified and hence not adequately considered in the discussion; 1. the snorkel device would appear to allow much greater time for inhalation than normally occurs during swimming. This would automatically increase the VO2 max of all subjects compared with free swimming. 2. Triathletes swim legs are typically 1500m. Thus...
