Risk-benefit paradox of exercise revisited: Male sexual libido

Issue: BCMJ, vol. 59 , No. 4 , May 2017 , Pages 212-214 Letters

In 2016 the BCMJ published content on the risk-benefit paradox of exercise[1] in cardiac adverse complication/prevention and cancer risk.[2]

An article published ahead of print on 13 February 2017 in Medicine & Science in Sports & Exercise reveals a study from University of North Carolina on 1077 subjects on endurance exercise training and male sexual libido. The authors conclude that exposure to higher levels of chronic intense and greater durations of endurance training on a regular basis are significantly associated with decreased libido scores in men. In this study, both moderate and light physical activity is associated with relatively high libidos.[3]

This is another example of the risk-benefit paradox of exercise.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
