Disorders in the menstrual cycle are more common in young Finnish athletes than in peers who do not play sports, according to a recent study by the University of Jyväskylä's Faculty of Sports Science.
According to the study, nearly 40 percent of 18- to 20-year-old athletes reported menstrual disorders, compared with only 6 percent of non-athletes.
No such difference was observed in 14–16-year-olds.
Based on studies in other countries, menstrual disorders are known to be relatively common in female athletes.
Based on previous literature, it is known that one of the most common causes of disturbances is too low energy supply in relation to consumption, says doctoral student Suvi Ravi in the press release.
The study also showed that athletes were more satisfied with their body weight than other young people.
However, about 20 percent of athletes and 40 percent of non-athletes said they were dissatisfied with their weight.
The study involved girls and young women who belong to a sports club, train at least four times a week, and do not belong to a sports club.
