Study summary

Labor itself can occur spontaneously vaginally, with the help of extraction methods, or via cesarean section. It can also be planned or awaited for the spontaneous onset of uterine contractions. Each method has its advantages and disadvantages regarding potential damage to the pelvic floor and its stability in vaginal delivery or extraction methods, or concerning the stability of the abdominal wall with subsequent wound healing after a cesarean section.

The aim of the study is to retrospectively and prospectively determine the impact of the method of delivery on the performance of female athletes through a questionnaire study. Investigators would like to answer the question of whether cesarean delivery means a later return to training for athletes, whether pregnancy is problematic for female athletes in relation to their BMI, and whether pregnancy often signifies the end of a sports career for female athletes. The questionnaire also includes questions regarding overall women's health-menstrual cycle, incontinence, and mental health of female athletes. Prospectively, the questionnaire will be sent to all female athletes who meet representation limits once a year and for two years after retiring from the national team.

Read the detailed description

Childbirth and pregnancy are among the most significant moments in a woman's life. The method of delivery is currently a highly debated topic with potential impacts on a woman's future physical and mental health. For elite female athletes, this issue is amplified, as pregnancy and childbirth significantly affect their performance and careers, and it is often necessary to plan pregnancies in consideration of current sporting events and ongoing physical training.

Each method has its advantages and disadvantages regarding potential damage to the pelvic floor and its stability in vaginal delivery or extraction methods, or concerning the stability of the abdominal wall with subsequent wound healing after a cesarean section.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 18, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
