Introduction: This study was designed to investigate the effect of polarized exercises on the duration of important electrocardiographic indicators in active young girls. The indicators of interest include 1) P wave amplitude, 2) T wave amplitude, 3) QRS complex duration, 4) RR segment interval duration, 5) QT interval duration, 6) PR segment duration, and 7) ST segment duration.
Materials and Methods: twenty healthy young women (Age 22.8±1.57 years; BMI 22.26±2.8kg/m²) were recruited for this study using a purposive sampling technique. All participants were characterized as physically active, reporting a sustained history of participation in competitive endurance sports, including volleyball, and ..., in addition to regular experience with resistance trainings . Following baseline assessments, the subjects were randomly divided into two experimental groups (n=10 n=10 per group) for the subsequent intervention phase. control and polarized exercise. Participants in the POL training performed 3:1 POL training (3 minutes at 70% and 1 minute at 90% of maximum heart rate) for 8 weeks, 3 times a week, and each session lasting 12 minutes. The subjects' ECGs were taken one day before the start of the test and after the end of the test and analyzed using a paired t-test to compare the means of the training protocols. The significance level in all analyses was considered to be 0.05.
Results: Indicators significantly improved/increased following polarized training(P<0.05).
Conclusion: These results suggest that the (POL) model, as implemented over the 8-weeks protocol, successfully induced positive and statistically significant improvements in the measured cardiovascular health parameters.
