  • Abduction / Valgus Kinematics of Lower Leg Relative to Femur
    Richard J. Howell

    This outstanding body of research is a watershed in the fight against ACL-injuries. This group should be richly commended for this excellent work.

    The work points to (a priori) how, in the case of alpine skiing, excessive abduction loading / valgus torque of the lower leg structure relative to the upper leg (about the knee) can be truncated by "detaching" the imposing load from the point of load application at t...

  • Anticipatory regulation are cognitive and affective processes involved?
    Henare Broughton
    I read your fascinating article with much interest. Do you think that in simple terms that anticipatory regulation may be an aspect of the decision-making the athlete makes before execution of an action. In the instance of longer duration exercise eg a marathon a decision is made then physiological systems amongst others come into action as you have described. Prior learning and adaptation may be involved as well as genetic and en...

  • A win for the FMARC and Football
    Adedayo Osholowu
    Age cheats are a common problem in Youth Tournaments in Sub Saharan Africa with poor record keeping practices in rural areas. The MRI will help greatly in our quest to stamp out age cheats but more research needs to be done to determine the sensitivity of the MRI in determining ages of African Athletes as current evidence shows that there may be some false positives going by the current grading system. Some scientists ar...

  • No discrepancy between protocol and trial report
    Gro Jamtvedt

    We thank Professor Thornton for raising these issues and are grateful for the opportunity to clarify details of the trial protocol and analysis.

    There is, in fact, no discrepancy between the description of outcomes in the trial protocol published on the trial web site, the protocol that was registered on the Australian New Zealand Clinical Trials Registry, and the report published in the British Journal of Sports...

  • Evolution and pacing strateges
    fergus j dignan

    I read the review article on the anticipatory regulation of performance and pacing strategies by Dr R Tucker in the June edition of BJSM with great interest. The idea that there is a part of the brain, as yet undiscovered,which enables one to judge the optimal work rate for a given task, is an intriguing one. From a Darwinian view point, the idea of there being a template in the brain that one could draw upon in determin...

  • An earlier community study
    Yukitoshi Aoyagi

    Dear Editor

    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 clue to the important question of season is that invitations were sent out over a 20-week period, beginning in September of 2006. In discussing their data, the authors claim (p...

  • To avoid Confusion about Lower Limbs Stiffness Unit of Measurement
    Sylvain Durand

    Dear Editor

    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 an important element of the muscle biomechanical characteristics and the optimal utiliz...

  • Relative age effects in NHL draftees revisited: A response to Hancock, Ste-Marie and Young (2008)
    Joseph Baker

    Dear Editor

    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 (NHL) draftees.


    Hancock et al. proposed that the more appropriate method for examining relative ag...

  • Edward J.C. Dawe

    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 total race time, especially if an individua...

  • Discrepancies between protocol and trial report
    Jim G Thornton

    Dear Editor

    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. I have a few questions.

    It is stated that “two primary outcomes and 12 secondary outcomes were specified a priori in the analysis plan” but only the two primary outcomes and five secondary outcomes appear in the paper. Four secondary...
