Data presented as mean±SD. Statistical analysis used repeated measures with bonferroni pairwise comparison between experimental and control groups during three times: before and after five minutes (1-2), before and after one hour (1-3), and after five minutes and after one hour (2-3). Statistical difference between group 2 and 3 vs. group 1
