Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this crossover clinical trial is to investigate the acute physiological effect of exercise on the uterine and fetal blood flow in pregnancy. The main questions it aims to answer are:

* What is the acute physiological effect of exercise on the uterine and fetal blood flow in pregnancy?
* What is the acute physiological effect of continuous aerobic exercise versus resistance exercise on the uterine and fetal blood flow in pregnancy?
* What is the effect of physical activity levels on the uterine and fetal blood flow in pregnancy?

Researchers will compare the continuous aerobic exercise to the resistance exercise with a 3-6-week interval to examine the acute physiological effect on the uterine and fetal blood flow.

Participants will:

* Fill in a physical activity level questionnaire at baseline.
* Complete either continuous aerobic exercise or resistance exercise and take blood flow measurements.
* Complete the remaining type of exercise after a 3-6-week interval and take blood flow measurements.

Study Groups

Continuous aerobic exercise

The continuous aerobic intervention was performed on a bicycle in a seated position at a moderate exercise intensity. Heart rate and RPE was implemented to ensure moderate intensity level. The participants were allowed to warm up for 5 minutes before starting to cycle at the predetermined HR ranges for 25 minutes. The total duration of exercise was 30 minutes.

Group Type EXPERIMENTAL

Exercise

Intervention Type OTHER

The intervention consists of two different types of moderate intensity exercise: Continuous aerobic and resistance exercise.

Resistance exercise

The acute resistance intervention consisted of four exercises performed using Technogym equipment at a moderate intensity. Every exercise consisted of 3 sets of 20 repetitions, with 1 minute rest in between sets, equaling 30 minutes of exercise in total. The four exercises were performed using the following Technogym devices: vertical traction, chest press, low row, leg press. Prior to the start of each exercise, a short maximal resistance test provided by the Technogym equipment was executed to determine moderate intensity.
