Survey study, 2018 # How does intense karate training affect the menstrual cycle in young female athletes? Most young karate athletes had menstrual disruptions like PMS or painful periods, likely caused by intense training. Early or limited evidence Young female karate athletes in puberty and adolescence ## What they did Researchers studied the menstrual cycles of karate athletes in puberty and adolescence. They interviewed and measured athletes and recorded their menstrual cycle patterns and symptoms. ## What they found Among athletes in the puberty age group, 6 athletes (26.09%) had clinical PMS and 9 athletes (39.13%) had painful menstruation. Menstrual disruptions were most common in athletes who had started training before their first period and had a muscular body type. Intense training and competition stress were identified as the main cause. ## What it means for you High-intensity training may disrupt menstrual cycles in young athletes. A major limitation is that the study does not clearly report the total number of athletes studied overall, making it difficult to understand the overall prevalence of menstrual problems in this population. 6 athletes with PMS (26.09%) 9 athletes with painful periods (39.13%) most experienced some menstrual disruption ## About the study Original title Analysis Of The Menstrual Cycle In Athletes Of Different Age Groups In Kyokushinkai-Karate Authors K.

Bugaevsky K. A., Cherepok A. A. Analysis of the menstrual cycle in athletes of different age groups in kyokushinkai-karate. Purpose: to present the comparative results of the conducted study on the study of the features of the dynamics of the ovarian-menstrual cycle in athletes of puberty and adolescence engaged in kyokushinkai-karate. Material and methods analysis of scientific and methodological literature; anthropometry, questioning and interviewing; Methods for determining morphological index values and mathematical statistics. Results: the data on the revealed individual somatic changes in sexual somatotypes, as well as individual violations of the ovarian-menstrual cycle in the revealed sex somatotypes, conducted in the process of medical and pedagogical observations of athletes engaged in kokushinkai-karate. Conclusions: it was found that most of the athletes of both age groups involved in this sport are experiencing various, often combined violations of the ovarian-menstrual cycle, as a result of individual adaptive changes in their body to physical and psycho-emotional stress. The analysis of the dynamics of the process of formation and flow of CMC in athletes of pubertal age testifies to the prevalence of violations of the ovarian-menstrual cycle in the group of athletes who started exercising to menarche and referred to the mesomorphic sex somatotype - 6 (26.09%) athletes of the pubertal age group defined clinical manifestations of premenstrual Syndrome (PMS) and in 9 (39.13%) - the phenomenon of algodismenorea.It has been established that the intensity of the training and competition process is the dominant cause of the infringements of the reproductive system of young athletes and the changes in anatomical and morphological indicators determined in the study, with the formation of various types of somatic disorders in the overwhelming number of girls, especially mesomorphic and andromorphic sex somatotypes. Based on the analysis of the obtained data on the dynamics of ОMCs in sexual somatotypes, it can be considered that all the revealed changes in ОMC are related to the phenomena of the process of adaptation of the organism of athletes of both age groups to intense physical and psycho-emotional loads.
