TY - JOUR T1 - A Comparison of the Effects of Two Methods of Aerobic and Combined Exercises on the Changes of Angiogenesis Factor TGF-β1 and Cortisol Hormone in Healthy Elderly Men TT - مقایسه اثر دو شیوه تمرینی هوازی وترکیبی بر تغییرات فاکتور آنژیوژنزی TGF-β1 و هورمون کورتیزول در مردان سالمند سالم JF - Yafteh JO - Yafteh VL - 21 IS - 4 UR - http://yafte.lums.ac.ir/article-1-2905-en.html Y1 - 2020 SP - 32 EP - 43 KW - TGF-B1 KW - cortisol KW - aerobic training KW - combined training KW - age N2 - Materials and Methods: In this semi-experimental study, 30 healthy elderly men were divided into 3 groups of aerobic exercise, combined exercise and control group. The exercise sessions were held 3 days a week for 8 consecutive weeks. Aerobic training with an intensity of 60-75% of maximal heart rate reserve was performed. Combined exercises at the same percentage of maximum heart rate and resistance trainings consisted of 5 movements with 60% 1RM intensity which had reached to 75% during the training weeks. ANCOVA and t-test were used to compare the inner and inter group averages at the significant level of P≤0.05. Results: Compared to the control group, the results of the present study showed significant changes in TGF-β1 level (P = 0.015) and cortisol (P = 0.016) in the training groups because of aerobic and parallel trainings. According to the post-test measures, TGF-B1 increased in the combined and aerobic groups, and cortisol significantly decreased in the combined group compared to the pre-test results. M3 ER -
