Anterior cruciate ligament injuries in Australian football: should women and girls be playing? You're asking the wrong question.

BMJ Open Sport Exerc Med 2020 9;6(1):e000778. Epub 2020 Apr 9.

Centre for Sport Research, School of Exercise and Nutrition Sciences, Deakin University, Geelong, Victoria, Australia.

Anterior cruciate ligament (ACL) injuries have been a rising concern in the early years of the women's Australian Football League (AFLW), eliciting headlines of a 'knee crisis' surrounding the league. There has been a focus on female biology as the primary factor driving the high rate of ACL injuries in the AFLW. Emphasising Australian football (AF) as being dangerous predominantly due to female biology may be misrepresenting a root cause of the ACL injury problem, perpetuating gender stereotypes that can restrict physical development and participation of women and girls in the sport.

Hypogonadism in Exercising Males: Dysfunction or Adaptive-Regulatory Adjustment?

Front Endocrinol (Lausanne) 2020 31;11:11. Epub 2020 Jan 31.

Department of Exercise and Sport Science, Department of Nutrition, Gilling's School of Global Public Health, University of North Carolina, Chapel Hill, NC, United States.

For decades researchers have reported men who engaged in intensive exercise training can develop low resting testosterone levels, alterations in their hypothalamic-pituitary-gonadal (HPG) axis, and display hypogonadism. Recently there is renewed interest in this topic since the International Olympic Committee (IOC) Medical Commission coined the term "Relative Energy Deficiency in Sports" (RED-S) as clinical terminology to address both the female-male occurrences of reproductive system health disruptions associated with exercise. This IOC Commission action attempted to move beyond the sex-specific terminology of the "Female Athlete Triad" (Triad) and heighten awareness/realization that some athletic men do have reproductive related physiologic disturbances such as lowered sex hormone levels, HPG regulatory axis alterations, and low bone mineral density similar to Triad women.
