The Comparision of two methods of continuous and interval training for eight weeks on Aplin 13 and fibroblast growth factor in elderly rats

This study aimed to compare the two methods of continuous and interval training for eight weeks on Aplin 13 and fibroblast growth factor in elderly rats.

In this study, 30 elderly male rats were randomly divided into three groups of continuous training (n=10), interval training (n=10), and control group (n=10). Interventions were performed for eight weeks. Blood samples (3 cc) were taken from the tails of elderly male rats 72 h before and after the last session of the protocol to evaluate the research variables (Aplin 13 and fibroblast growth factor). One-way analysis of variance was used to analyze the findings, and the Tukey test was utilized for the homogeneity of variance of groups. All statistical tests were performed in SPSS software (version 17) at a significance level of α=0.05.

Aplin 13 had a significant increase in the continuous exercise group (P<0.05). Moreover, the fibroblast growth factor was significantly increased in the continuous exercise group (P<0.05). Aplin 13 had a significant increase in the interval exercise group (P<0.05). Fibroblast growth factor was significantly increased in the interval exercise group (P<0.05). No significant changes were observed in the control group.

The results of this study showed that eight weeks of continuous and interval training caused a significant increase in the levels of Aplin 13 and fibroblast growth factor in elderly male rats. Therefore, these exercises and especially periodic exercises can be used as a suitable way to increase angiogenesis in the elderly.
