  • Re: Stretching before and after exercise
    Ian Shrier

    Editor,

    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...

  • 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...

  • PERFORMANCE ANOMALIES IN RUNNING-SHOE DESIGN: PSYCHOLOGICAL FACTORS?
    Tony H. Reinhardt-Rutland

    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...

  • CONSIDER HYPOXIA NOT OVERLOAD
    Jennifer M Robinson

    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...
