Objective: To observe the effects of 12 weeks of yoga on blood pressure level and vascular endothelialfunction in healthy young women. Methods: Healthy young women were selected as the study subjects and dividedinto training groups, with 12 people in each control group, and the training group underwent yoga training for 3hours/day and 5 days/week, a total of 12 weeks. The control group did not engage in any physical activity. Beforetraining and after 12 weeks of training, factors related to blood pressure (systolic, diastolic, heart rate and pulsepressure) were performed; Vascular endothelial function related indexes (endothelin 1, nitric oxide, endothelial nitricoxide synthase) levels; Other body composition indicators (weight, body fat, BMI, muscle content) testing. Results:After 12 weeks of yoga training, the level of diastolic blood pressure decreased significantly (p<0.05), the level ofendothelin 1 decreased significantly (p<0.05), the contents of NO and eNOS increased significantly (p<0.05), thebody fat percentage and BMI index decreased significantly (p<0.05), as far as we can get that there was no obvious difference in the matched group (p>0.05). Conclusion: 12 weeks of yoga training can effectively reduce diastolicblood pressure and ET1 levels, increase the content of NO and eNOS, reduce body fat percentage and BMI index inhealthy young women, and have a certain effect on blood pressure level and vascular endothelial function in healthyyoung women.
