    How soon after completion of the exercise regime were the cognitive measures taken, and what was the average length of the followup?

  • A simple approach to a healthy lifestyle

    Dear Editor,

    Saturated fat is an essential element in our diet. Our body uses saturated far for energy, hormone production, facilitating vitamin absorption and most importantly, for coating and padding to protect our cellular membranes and organs. In the last two decades, saturated fat has been demonised as the main culprit leading to fatty deposits in the coronary artery and causing heart attacks (myocardio-infarction) when the deposits block up the artery. The truth is that myocardio-infarction is not directly caused by deposition of saturated fat called ‘plaque’ in our coronary arteries. The main cause of myocardio-infarction is the rupture of the plaque [1]. The main cause of rupture is inflammation [2-4]. There are many factors which will trigger an inflammation response in our body. These include: infection, stress, allergy, and injury…etc. Other genetic factors and social and environment factors also play an important role. I salute the authors of this paper for their strong spirit of science, identifying new evidence which challenges previous views. “The important thing is not to stop questioning. Curiosity has its own reason for existing”. - Albert Einstein As an epidemiologist, public health practitioner and an educator, I concur with the author’s suggestion of the non-pharmaceutical approach to maintain good health. This simple approach involves an easy short daily walking exercise and eating a good balanced diet with...

  • The type of fat matters
    Vidur Kapur

    Dear Editor,

    I read with interest the narrative review by Timothy David Noakes and Johann Windt

    However, the very name of this diet, 'low-carb, high-fat' can be misleading, because it does not tell us which type(s) of fat such a diet is high in. To the extent that low-carb, high-fat (LCHF) diets are low in carbohydrates and high in monounsaturated and polyunsaturated fats (MUFAs and PUFAs, respectively), p...

  • Associations and causality
    M John Cooper

    Dear Editor,

    The article identifies "associations" between various sports and longevity. Associations do not deal with the issue of causality. Yet articles like this seem to imply that there is a causal relationship. I'm sure the authors would acknowledge that "correlation does not imply causation". Yet articles like this seem to imply that "yes, we know we haven't proved causality, but (nudge nudge, wink wink) we...

    As for Fifa standards this is very lovely explained as well. The benefit of activity is in common interest of health professionals and the state.

  • Response to: "Does sports participation (including level of performance and previous injury) increase risk of osteoarthritis? A systematic review and meta-analysis"
    Kate A. Timmins

    Dear Editor,

    We read with interest the systematic review by Tran and colleagues recently published online(1). The findings build on our own observations in a systematic review of running and knee osteoarthritis (OA)(2). Although the focus of our review was narrower than that of Tran et al, which investigated evidence relating to OA of all joints across a variety of sports, we would like to comment on some of the si...

  • Oral Health Screening in Pre-Participation Medicals
    Marcos A. Miranda

    For over 40 years oral health screening is part of all pre- participation medical examinatios at the Portuguese Sports Medicine Centers in The National Institute of Sports. Preparticipation medicals are compulsory for all athletes who wish to play competitive sports and none gets full clearance without a full treatment of any oral/dental pathology. We are aware that oral health is fundamental to maintain sports performance...

  • This editorial is misleading
    Modi K Mwatsama

    Dear Editor,

    This editorial is misleading. Claiming that the Eatwell Guide is not evidence based is factually wrong. The Guide is based on comprehensive expert reviews of the evidence undertaken by the independent Scientific Advisory Committee on Nutrition (SACN) which advises government, and its predecessor, the Committee on Medical Aspects of Food Policy.

    The latest revisions to the Eatwell Guide were i...

  • Two forward, one back in concussion
    William Stewart

    Dear Editor,

    I commend Raftery et al in their recent editorial on concussion assessment in sport, in particular rugby's response on this matter (1). Undoubtedly one of the major issues facing sport is the lack of clarity and consistency in identifying concussions on the field; a symptom of the deficiencies in the last output from the Concussion in Sport Group (the 'Zurich Consensus')(2)

    However, while a c...

  • Efficacy versus effectiveness
    Gareth A. Thomas

    Dear Editor,

    As a rural and purely clinical sports medicine practitioner, I fully agree with the premise of this article. Whilst applauding the wonderful data being produced from around the world, so little of it has any relevance in my practice. There appears to be much back slapping happening in the research centres, though so little work on effectiveness of exercise regimes. I agree that the focus on rigorous meth...
