  • comment on "eight new papers deepen our understanding of the regulation of human exercise performance".
    george d aber

    I am a 67 year-old middle and long-distance running coach (level V). Nearly 6 decades ago I began running, and cut my athletics teeth on the old CAC model proposed by A.V.Hill.

    Today, after over 2 decades of being a student of exercise physiology, I am fascinated by this new concept proposed by Prof. Noakes.

    Many years ago I read that exercise-induced fatigue was a psycho- physiological phenomina that...

  • This is my solution!
    T. Mar

    This article provides the solution to my problem as I have been suffering with back pain half way into my bike rides. I felt that my pelvis was too tilted towards my chest when riding but had no clue on how to correct it. Had I known ages ago that it was as simple as changing the angle of my seat then I would have had even more great rides, so just want to say Thank You for putting this article out there.

  • Re:Subjective measure of monitoring exercise performance: Borg scale
    Flavio O Pires

    I am very grateful with the interest and comments by VIKRAM MOHAN and SRIJIT DAS. I consider that the approach suggested with chronic obstructive pulmonary disease subjects may be helpful to clarify to which extension the capacity in identifying correctly the workload could have been due to the afferent feedback from cardiopulmonary system. I also agree that the rate pressure product would be an interesting variable to b...

  • Life-long TV remote exercise better for the heart than physical exercise
    Rajat Chauhan

    Dear editor,

    It was a very interesting editorial and I must congratulate the authors for that.

    In my humble opinion, even if the studies quoted are right, the title of the editorial is simply wrong. Even though the author tries to be politically correct in the concluding paragraph, most readers wouldn't make it there and would have made up their minds. Does that mean even the guys doing moderate brisk walk...

    Tony H. Reinhardt-Rutland

    Ratzlaff (1) outlines broad categories in assessing societal activity-levels: occupational and household. While the latter was traditionally the greater source of activity, particularly for men, the nature of work has become steadily more sedentary. However, the same may be less true for household tasks. One conclusion it that women today, as the gender likely to undertake most household tasks, may well be more active than th...

  • Missing biochemical pathways suggest benign benefits of beetroot and other NO precursors
    Catherine Collins

    Nitrates boost blood supply and recovery to muscle groups via the iNOS pathway, but only if converted to nitrites via salivary bacteria. The use of mouthwash, a common practice in those consuming diets high in refined carbohydrate, completely negate this possible conversion (1)

    That the authors overlooked the potential risk of nitrosamine formation from the combination of nitrite-precursor nitrates with dietary...

  • Osteoarthritis in sportsmen/women and people in general
    MSc Ihosvany Castellanos Santos

    Osteoarthritis is the most common form of joint disease, sparing no age, race, or geographic area. Symptomatic disease also increases with age. This arthropathy is characterized by degeneration of cartilage and by hypertrophy of bone at the articular margins. Inflammation is usually minimal. Hereditary and mechanical factors may be variably involved in the pathogenesis.

    Degenerative joint disease is traditionall...

  • Response to Valerie Bougault, Louis-Philippe Boulet Br J Sports Med 2012;46:402-406
    Harri Hemil

    Bougault and Boulet write that there is a high incidence of viral respiratory infections in elite swimmers, in particular during heavy training programmes. However, Bougault and Boulet do not mention the evidence indicating that vitamin C may protect against respiratory infections of athletes.

    In five placebo-controlled trials with participants under heavy acute physical stress, vitamin C supplementation halved...

  • Shockwave in MTSS: more questions than answers?
    Bhavesh D. Kumar

    Dear Editor,

    I commend the authors for their efforts in conducting a prospective clinical trial on this therapeutically challenging condition [1]. They developed nice reproducible intervention protocols, and appeared to have access to a good flow of appropriate subjects that could be followed-up relatively easily.

    Reading beyond the abstract, however, there is ample evidence that the headline result...

  • Sickle Cell Trait: what's a sports laboratory clinician to think?
    Giuseppe Lippi

    I read with interest the editorial of O'Connor et al on screening for the presence of sickle cell trait (SCT) in student athletes (1). Although some aspects are indeed agreeable, such as the need of continued research to strengthen the rationale for either continuing or revoking SCT mandatory testing in student athletes, there is however a drawback in their analysis that must be clearly emphasized. The cost-effectiveness...
