  • 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...

  • Quantitative Assessment of Cognitive Molecules Supplementary to Doping Test
    Atif A Baig

    Dear Editor,

    We have read the respective article, and we agreed to all stated observations and recommendations. This is a very useful article for many researchers and especially for the scientists working with addiction sciences.

    We would just like to emphasise on the use of quantitative assays for the cognitive molecules (Lee et al., 2009) beside doping test. Mental performance is the attribute of three...

  • Time loss injuries compromise team success in Elite Rugby Union
    Henare R Broughton

    Dear Editor,

    Injury data from the RWC 2011, 89.1 per 1000 player-hours2011 and the earlier tournament of 2007, 83.9 per 1000 player-hours may have had an effect on all teams.

    But success could only be accorded to the winner in the final match. The All Blacks had a long history of not even making the semi-finals. However the RWC 2011 success was not due to the negative effect of injury on the team but rath...

  • Re:The Devil Is In The Detail
    Jonas B. Thorlund

    Dear Editor,

    We thank Dr. Bollen for his interest in our paper on knee arthroscopy for the middle-aged and older patient with a painful knee (Thorlund et al. 2015a,b).

    The consistent high-level evidence (Thorlund et al. 2015a,b; Khan et al. 2015) questioning the benefit of arthroscopic surgery has so far had a very limited effect on the practice of arthroscopic surgery in middle-aged and older patients with a...

  • New and old: enjoyment of free air
    Martin Hofmeister

    The German physician Christopher William Hufeland (1762 - 1836) wrote in his famous work 'Art of Prolonging Life' in 1797: "Harmony in the movements is the grand foundation on which health, uniformity of restoration, and the duration of the body, depend; and these certainly cannot take place if we merely sit and think. The propensity to bodily movement is, in man, as great as the propensity to eating and drinking. Let us...

  • The Devil Is In The Detail
    Steve R Bollen

    I would like to comment on the conclusions of the recent published meta-analysis by Thorlund et al in the BMJ and the subsequent sensationalist editorial. The conclusions are at odds with my own personal experience and that of my peer group.

    Although the methodology of the study is valid I would take issue with the conclusions reached.

    The meta-analysis on benefit started with nearly 1800 studies and wa...

  • 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...

  • Serum Testosterone In Sedentary, Active And Athletic Males From Kosovo
    Gezim Murseli

    Testosterone is one of the anabolic androgen steroids (AAS) that has been abused to improve higher athletic performance by enhancing muscle development and recovery. 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...
