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. These indicators can well show changes in heart function in response to physical exercise and help us measure the effect of these exercises more accurately.
Materials and Methods: 20 young girls (20 to 26 years old) who were physically active were selected in a purposive design and randomly divided into two groups of 10: control and polarized exercise. Participants in the polarization training performed 3:1 polarization training (3 minutes at 70% and 1 minute at 90% of maximum heart rate) for eight weeks, three 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 two training protocols. The significance level in all analyses was considered to be 0.05.
Results: The results showed that the length of the indicators in question significantly increased after polarized training (P<0.05).
Conclusion: These findings suggest that practicing polarized exercises can have a significant effect on cardiovascular health in a short period of time.
