  1. Data are presented as mean ± SD. N = 10/group. Two-way ANOVA followed by Tukey test. N = 10/group.
  2. Untrained, Non-exercised group; 1xHIIT, High-intensity interval training performed in single daily sessions; 3xHIIT, High-intensity interval training performed in three shorter daily sessions.
  3. *p < 0.05 PRE versus POST.
  4. #p < 0.05 1xHIIT and 3xHIIT versus Untrained at post-training period.
