Abstract
To study the effects of intensive physical training on menstruation, twenty-eight female RMC cadets filled out a menstrual questionnaire after completion of an eight-week Basic Officer Training Course (BOTC). Average age at onset of training was 18.4 years with menarche (first menstruation) occurring at 12.9 years of age. Sixty-five percent of the females were "responders", i.e., noting changes in their menstrual patterns. These changes consisted of a decrease in the amount and duration of menstrual flow and increase in the length of menstrual cycles. Only one female experienced absence of menstruation (amenorrhea) during the course of training. No effects were detected on the severity of pre-menstrual symptoms or in the degree of dysmenorrhea (painful menstruation). Within six weeks of graduation from BOTC, eighty-five percent had regular menstrual cycles.
