Streszczenie

A group of 106 mature female recreational runners were studied in the context of their menstrual irregularities due to cycle length, menstrual cycle loss. Influencing factors such as running intensity, years of training, BMI, vitamin D intake were considered. The hormonal fluctuations associated with menstrual irregularities over a woman’s lifetime can lead to the initiation of a health cascade and the onset of many serious diseases such as osteoporosis and cardiovascular episodes. Observing the menstrual cycle in women who train to run provides insight into early indicators of more serious health problems that may affect them. Polymenorrhoea, oligomenorrhoea, secondary amenorrhea as well as amenorrhea of less than 3 months can be observed among mature women running recreationally. The irregularities examined may have important implications for women’s overall health. Influencing factors: BMI – does not correlate with menstrual interruption and secondary amenorrhea; training intensity – does not correlate with secondary amenorrhea, i.e., no relationship with distance run, number of training days, or length of training per day; years of training – correlates with longer menstrual interruption and secondary amenorrhea; vitamin D – correlates with number of cycles per year.
