  • 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...

  • Striking follow-through (or lack thereof) may explain difference between knee injuries amongst boys and girls
    Matt M. Carver
    I recently read an article in the Wall Street Journal regarding football/soccer injuries amongst boys and girls. It referenced your medical study concerning the prevalence of knee injuries to the strong leg of boys, but to the weak leg of girls. As a former player of 20 years and coach for the past eight, I have a theory on this divergence. If a player strikes strongly through a ball, he lands on his striking leg (which is the str...

    Ryan et al (1) provide empirical evidence that standards for running shoes in relation to foot posture are far from convincing. In particular, a sophisticated and expensive motion-control design intended for highly pronated feet was less effective than more basic shoes in minimizing injuries and pain to all categories of foot. This outcome echoes Richards et al's (2) recent negative review regarding the role of shoe desi...

  • Re: Are there risk factors in alpine skiing? from Hasler et al., Br. J. Sports Med. 2009 43:1020-1025; doi:10.1136/bjsm.2009.064741
    Gerhard Ruedl
    Dear Editor, We read with interest the article from Hasler et al. (2009) "Are there risk factors in alpine skiing? A controlled multicentre survey of 1278 skiers". In general, the answer is: 'yes, there are internal (e.g. gender, age, fitness, skill level, risk taking) and external (equipment, environment) risk factors' according to comprehensive model for injury causation by Bahr and Krosshaug (1). However, we would like to comm...

    I read with appreciation Cook and Purdam's article, as this continuum model is probably quite helpful in determining treatment choices. Where the article falls short though is the unproved presumption that the key initiating factor is over load. In perpetuating this oft quoted presumption the article fails to acknowledge the large population who develop tendon pain without overload/ overuse.

    I suggest that othe...

  • Re: Truth about Vonwilliebrands' disease
    Carolyn Broderick

    von Willebrand's disease is an inherited bleeding disorder which can affect the quantity /- the quality of von Willebrand factor. It is more common than haemophilia and there are 3 main types.

    Type 1 (by far the most common and accounting for > 70% of cases) is usually associated with mild bleeding symptoms (epistaxis, easy bruising, menorrhagia etc) and may be diagnosed later in life.

    Type 2 is...

  • Truth about Vonwilliebrands' disease
    Bruce G DeVenne

    This article is totally wrong. Vonwillebrands' disease is not a mild form of Haemophilia. It is a totally separate and, at my level, life threatening bleeding disorder. Haemophilia is found in the sex linked X chromosomes while Vonwilliebrands' disease is in the autosomes and not sex linked the male or female can be hit with this disease. My great Aunt bled to death from it. It has no comparison to Haemophilis. Haemophilia...

  • Homo Sedens
    Ragnar Viir

    Dear Editor,

    My colleagues and I read with great interest your Editorial proposing a new paradigm of inactivity physiology. This would be useful. In order to properly discuss all aspects of any problem it clearly is necessary to be able to name each precisely.

    There is a clear distinction between not exercising and prolonged sitting, though I would suggest that "seated immobility" as advocated by Bea...
