In response to “What factors are associated with physical activity in older people, assessed objectively by accelerometry?” (abstract, full article): We have read with interest the recently reported accelerometer study of physical activity in community-living seniors in Oxfordshire (1). Subjects were observed for 7 days, apparently in the winter or the spring, although the only […]

E-letter: Race success in Triple Iron Triathlon associated with running performance
Dear Editors, Knechtle and Kohler have considered the factors relating to overall performance in triple ironman triathlon. There are however several other considerations which must be made when looking at total race time. The mental preparation needed for ultra-endurance events may have a significant impact on total race time. This can limit training time and […]
E-letters: Negating the safety advantage in running shoe design
By Tony H. Reinhardt-Rutland, University of Ulster Richards et al (2009) refer to a popular running shoe design entailing a heightened sole and pronation control. It is claimed to reduce running injuries, but in fact no evidence has been obtained to show that the design actually achieves its purpose. May I add another thought on […]
E-letters: Lower Limbs Stiffness Unit of Measurement
Dear Editor-in-Chief, We are concerned with an important confusion about data unit of measurement presented by Girard et al. when evaluating the changes in Lower Limbs Stiffness (LLS) during prolonged tennis playing (1). Evaluation of LLS is of great interest in a sport like tennis where speed and reactivity takes a great part. LLS is […]
E-letters: Relative age effects in NHL draftees revisited
A response to Hancock, Ste-Marie and Young (2008) by Joseph Baker and A. Jane Logan, York University. We appreciate the thoughtful review of our manuscript by Hancock, Ste -Marie and Young.(1) In this brief response, we reconsider the issues raised in their review and continue the discussion of relative age effects in National Hockey League […]
E-letter: Discrepancies between protocol and trial report
Sir, This is likely to be the definitive trial on the effectiveness of pre-exercise stretching for some time, so it is important that it is carefully reported and analysed in this paper by Jamtvedt et al. I have a few questions. t is stated that “two primary outcomes and 12 secondary outcomes were specified a […]
E-letter: More science please
By Justin A Paoloni I read with interest the Consensus Statement on Concussion, and believe this worthwhile in furthering scientific knowledge on concussion in sport. However, I have concerns about definitive comments in the consensus statement, given the lack of supporting scientific evidence. Whilst this consensus document is only “a guide and is of a […]
E-letter Re: Physical inactivity in the 21st Century
I very much enjoyed reading the ‘warm up’ article by Steven N Blair in the January edition of BJSM. The first study that he quoted on attributable fractions for all cause deaths was a real eye popper! I was very surprised to see that low cardiorespiratory fitness was a greater attributable risk factor (in both […]
E-letter Re: Separating Fatness from Fitness
By Bethany B. Barone and Kerry J. Stewart, Johns Hopkins University The use of absolute versus weight standardized maximal oxygen consumption during fitness testing has been debated, especially in the context of intervention trials that may induce weight change. We recently showed that exercise training-related changes in exercise systolic blood pressure (SBP) were independently predicted […]
E-letter Re: Handedness in Boxers
“Effects of left- or right-hand preference on the success of boxers in Turkey”, is an interesting and important addition to the research literature on the effect of handedness in sport. However, we believe that the explanation of the cause of the advantage of left- handedness is misleading and needs correction. Gursoy attributes the superior performance […]
