  • Low dose physical activity and the elderly
    Roy J. Shephard

    At the age of 86, I am a strong believer in the virtues of moderate physical activity for the elderly, walking some 5 km most mornings, and tending a substantial garden. Moreover, I agree with the proposition that for an elderly population, any physical activity is better than none, and that controlled experiments can be devised to demonstrate some of the short-term benefits of an increase in such activity. However, I w...

  • Non-contact anterior cruciate ligament injuries.
    Henare R Broughton

    It is common practice to refer lower limb injuries as non-contact, in this paper the categories have been clearly defined. The term pressing needs defining which may help the non soccer community. All lower limb injuries in football ought to be categorised as contact or in-direct contact with respect to the ground or an opponent. The principles of the Laws of Motion from Newtonian mechanics and basic physics might add fur...

The purpose of this study was to assess basal level of serum total testosterone in male athletes and to compare it with physically active and sedentary males.

    The study sample was composed of 40 males divided in four groups of different physical acti...

  • Time to bust the myth?
    Roy J. Shephard

    Recent editorials have renewed the debate on the role of physical inactivity in the current obesity epidemic. [1, 2] Malhotra and colleagues cite an opinion piece suggesting "little change of physical activity levels in the past 30 years," while Blair counters that U.S. Dept. of Labor statistics show "mining, agriculture and agricultural jobs declined substantially."

    Both statements have some truth, but they neg...

  • Coke and sports
    Matthew B. Kowalsky

    It is like saying Coca-Cola is the favorite drink of many athletes. The truth is much more complex. Research in this field that is funded by the beverages industry tends to be biased. There will always be people in any field, including scientific research, who will do almost anything to make a buck. I can understand the necessity of balancing the views on any public health issue, but here the balance is tipped over by an ev...

  • Re:12 Reasons why the "Physical Activity Myth" paper should not have been published; Request for retraction or modification based on open external peer-review
    Richard S Cooper

    Kelly et al make a number of useful comments about the unfortunate editirial by Malhotra et al. However they too obscure the main point. They use a 2008 NIH document as the key reference to refute the editorialists' claim that exercise does not lead to weight loss.

    What the NIH document actually says -

    The magnitude of weight loss due to physical activity is additive to caloric restriction, but physi...

    Karim Khan

    It seems very clear that there are two different ways of interpreting the tile of this editorial. BJSM is grateful for the terrific engagement in this important debate - we revel in debate.

    But it's not helpful to have two soliloquys going on so I respectfully suggest there are two basic interpretations of the title.

    Please click through to this Google Community http://ow.ly/PaHbz to see the two inte...

  • Review
    Gary Pearce

    This article speaks to the growing need to ensure all work groups including managers take the time to move around more frequently. It is also interesting to note that while this is based on short term studies it will have large long term gains. I will be very interested to see where this research goes in the future. I personally will be looking at ways to partake of this valuable insight in to the need to move away from...

  • since you asked for my opinion
    Rebecca A. Silverstein

    Since the web site clearly asked for my opinion, I felt I wanted to share how disappointed I am with this article.

    This article looks like it is simply a copy of a systematic review / metaanalysis published a full 13 months earlier, in september 2013, meaning that the search was current in March 2012.

    The review was criticized at the time of its original publication for being overly optimistic (see the...
