  • Response to "Is tendinopathy research at a crossroads?"
    Gareth A. Thomas

    I fully agree with comments made by Masci regarding treatment for tendinopathy. I also practice at the coalface, treating tendon pain from elite to recreational athletes. The reality I face when prescribing exercise protocols is both a lack of evidence base as to the optimum program, and the harsh reality that most non-elite athletes will not strictly comply with complex home exercise programs, particularly where there i...

  • Dichotomy in translation raises the need for careful definition in use
    Susan V. Baxter

    Clarification on the definition of use of the term 'intensity' as raised by Steele certainly serves to highlight the continuing variation - and confusion - around use of this term. Due to the ambiguity as to whether intensity is a measured load or is synonymous with perceived level of exertion, Steele recommended abandonment of intensity as a descriptive word.

    However it is my belief that the very dichotomy rai...

  • Economical with the evidence!
    Nick Webborn
    Although good to see researchers putting forward hypotheses for improving rehabilitation protocols I do believe there needs to be a balance of promoting their own work published in another journal (Scandinavian Journal of Medicine & Science in Sports) with incomplete presentation in an editorial article of another. In the original paper there were no differences between groups at 1, 6, and 12 months. There was no mention of t...

  • Stand up for better research - avoiding cherry picking when reporting results
    Ulrike Grittner

    With great interest we read Sj?gren et al.'s contribution that analyzed changes in telomere length in association to the time spent exercising and the time spent sitting in a 6-month randomized controlled trial in 49 older sedentary and overweight men and women. Sj?gren et al. concluded that reduced sitting time was significantly associated with telomere lengthening. These findings are of great potential interest, as hi...

  • Thoracic outlet and pectoralis minor syndromes in sports
    Richard J Sanders

    The article by Dr. Twaij and associates nicely covers the range of thoracic outlet syndromes (TOS) seen in athletes. However, several important points have been overlooked. The chief diagnostic tool for neurogenic TOS is physical examination that includes four provocative maneuvers: Upper limb tension test (ULTT}, elevated arm stress test (EAST), neck rotation, and head tilt. 1(Sanders2007) We agree with the authors...

  • Role of intermittent hypoxic expression of Hypoxia Inducible Factors and NFKB in endurance exercise
    Atif A Baig

    We have read the respective article and we agreed with all great findings. Nevertheless, we wish to emphasize the need to address the role of some molecular and physiological markers that may elaborate and possibly support the findings of the study. Intermittent hypoxia exposure can enhance the generation of red blood cells, which may consequentially increase hemoglobin concentration and hematocrit depending on the model...

  • Angiogenesis towards Adipogenesis: Role of vascular endothelial growth factor
    Atif Baig

    We have read the respective article and we agreed with all great findings. But just need to emphasized on some thing very important and crucial. We are working with adipocytes and adipose tissue is capable of expanding many-fold during adulthood, therefore requiring the formation of new vasculature to supply growing and proliferating adipocytes. The expansion of the vasculature in adipose tissue occurs through angiogenes...

  • Fundamentally important information
    Per B Mahler

    Having taught medical students about the benefits of PA for the past 20 years and lived through WHO's 2002 World health day on PA, I had the belief that PA was now integrated and implemented in everyday practice. This nice little piece of research reminds us how difficult it is to change "routine" and how uncomfortable some of us feel when encouraging people to change their behaviour. Back to the drawing board...

  • Endurane Running and nutrition
    david lucas

    The article suggests that using fat as an energy source is how to fuel endurance events.

    Why is it that top marathons runners and the SKY/GB team don't do this but have a good balance of mainly carbohydrate and protein?

    Because using fat requires 3% more oxygen for the same amount of energy. Thus energy release is slower and it is why top athletes train specifically to perform glycogen depleted. If you...

  • 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...
