Exercise during labor significantly reduces pain perception and increases beta-endorphin levels in women. This moderate-intensity cycling intervention appears safe for the fetus and stimulates uterine contractions, offering a natural analgesic effect.
Area of Science:
- Obstetrics and Gynecology
- Sports Medicine
- Pain Management
Background:
- Labor pain management is a critical aspect of childbirth.
- Non-pharmacological pain relief methods are increasingly sought after.
- Endogenous opioid systems may play a role in pain modulation during labor.
Purpose of the Study:
- To investigate the analgesic effects of moderate-intensity exercise during labor.
- To assess the safety and physiological impact of exercise on mother and fetus during labor.
- To explore the relationship between exercise, pain perception, and beta-endorphin levels.
Main Methods:
- Fifty women in labor participated in the study.
- Continuous moderate-intensity cycling on an ergometer for 20 minutes.
- Pain was assessed using a visual analogue scale (VAS) during rest and exercise.
- Blood samples were collected to measure beta-endorphin, cortisol, and catecholamines.
Main Results:
- 84% of women reported reduced pain during exercise compared to rest.
- 76.2% showed a significant reduction in VAS pain scores.
- Beta-endorphin levels increased significantly post-exercise (P < 0.001).
- Fetal heart rate remained within normal limits; uterine contractions increased (P < 0.05).
Conclusions:
- Bicycle ergometer exercise during labor is a safe intervention for the fetus.
- Exercise acts as a stimulus for uterine contractions.
- Labor exercise provides analgesia, potentially mediated by beta-endorphin release.

Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
