The effect of four weeks high intensity interval training (HIIT) and aerobic training on troponin T content in healthy male Wistar rats myocardial tissue

Background Cardiac troponin as a marker of heart, play a vital role in the diagnosis of heart disease. The purpose of this study was to assess the effect of four weeks high intensity interval training (HIIT) and aerobic training on troponin T content in healthy male rats’ myocardial tissue.
In this study, 36 Wistar rats 2 months with an average weight 180±20 were selected and randomly assigned divided into three groups, control (n=12), HIIT (n=12), and aerobic (n=12) groups; experimental group 5 days a week in accordance with their training program for 4 weeks to exercise. After 4 weeks, ANOVA test and Bonferroni post hoc test were used for analysis.
The results showed a no significant difference between the mean troponin T HIIT exercise and control groups. Troponin T is also a no significant difference between the Aerobic training and control groups.
Based on the findings of troponin T in none of the groups had no significant change, It seems that exercise HIIT and Aerobic training with duration of 4 weeks do not damage the heart tissue.
