Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Compression of the growing fetus against the IVC can cause supine hypotensive syndrome and fetal danger. However, there is no definite finding about the effects of exercise performed in the supine position. Jefferys et al. reported that the reduction in blood flow at rest is twice that that occurs during exercise and that the level of blood flow should not be a cause for concern in healthy asymptomatic women who choose to exercise in the supine position in late pregnancy. Based on this information, we predict that pelvic floor muscle exercises can change the hemodynamic responses of the IVC and reduce the compression on it.
In order to evaluate the effect of pelvic floor muscle exercises on hemodynamic responses of IVC and compression on it, pregnant and non-pregnant women will be measured by ultrasonography. Women eligible for the study will be seated and rested for 30 minutes before taking the measurement. Then, he will be taken to the supine position, rested for 2 minutes, and the first measurements will be taken at the 3rd minute. pelvic floor muscle exercises will be applied for 5 minutes as stated in the literature. Ultrasonographic measurements will be repeated in the supine position immediately after the pelvic floor exercises and 5 minutes after the exercise. Measurements will be applied to all participants in the same order. During the exercises blood pressure, heart rate and peripheral oxygen saturation will be monitored. Before and after the exercises, the heart rate and blood pressure parameters of the women will be recorded.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Pregnant women
Pregnant women aged 18-40, 20-40 weeks of gestation.
pelvic floor muscle exercises
Before the pelvic floor exercises are taught to all women participating in the study, a brief informational training about the function and structure of the pelvic floor and pelvis will be given using visuals. The application protocol will be given by experienced specialist physiotherapists who have received special training on pelvic floor muscle training. In this study, the training protocol described by Mørkved et al and Bø et al will be used. An exercise series will consist of slow and fast muscle contractions of the pelvic floor muscles. The exercise series will include 10 reps of maximum pelvic floor muscle contraction held for 6 seconds followed by three rapid muscle contractions. A 10-second rest period will be given between each exercise series. A total of 5 minutes, 4 repetitions of pelvic floor muscle contraction series will be applied, including the rest period.
Non-Pregnant
Being a non-pregnant woman who is in the same age range as the experimental group.
