Reliability of systolic time intervals as a measure of tension time index in athlete undergoing training
Author(s): Mrunalini Kanvinde, Vivek Nalgirkar and Sadhana Mendhurwar
Abstract:
The goal of this study was to find how systolic time interval is a reliable measure of tension time index in athlete undergoing training tension time index and systolic time interval as a evaluator of cardiovascular fitness in athletes. Depending on the need of oxygen to tissues V̇O2max increases with a increase in cardiac output, stroke volume, left ventricular ejection fraction and myocardial activity as a athlete does treadmill from moderate to maximal.
Data collection was done at Stress test lab. At Nerul, Navi Mumbai after taking permission from medical ethic committee. For proper results, athletes were asked to do treadmill for 2 weeks. Their systolic time intervals were assessed through 3D Echocardiography. Tension time index was calculated by using specific standardized formula.
In athletes, with a gradual increase in systolic time interval as left ventricular ejection phase and duration of systole (p<0.001) left ventricular ejection fraction was somewhat increased (p<0.005) without any change in pre-ejection phase with increase in tension time index (p<0.001).as athlete perform treadmill. Thus in athletes, tension time index is much more correlated with systolic time intervals (p<0.001).
Conclusion: Thus it was concluded that after doing treadmill, systolic time intervals is a best reliable measure of tension time index in athlete undergoing training. Thus there is a close relation between tension time index and systolic time intervals.
