Abstract
Objective: aging is known as a low bone mass and microarchitectural deterioration of bone tissue, resulting in increased risk of fracture. However, appropriate exercise for the prevention and treatment of osteoporosis has not been determined. The aim of this study was to determine the effects of compare effects of aerobic and resistance exercise training protocols with different intensities on microRNA-133a (mir-133a), Runx2 and Peroxisome proliferator-activated receptors-gamma (PPARγ) in bone marrow Wistar elderly rats. This experimental study was done on 40 Wistar male rats (23-month-old and with an average weight of 441.75 gram). They were randomly divided into five equal groups (n=8) include moderate (60% Maximum voluntary carrying capacity) or high (80% Maximum voluntary carrying capacity) intensity resistance training, moderate (60-110% Maximum speed) or high (80-110% Maximum speed) intensity endurance training and control. The two training groups completed 8 weeks of training program, 5 days a week according to resistance or endurance protocols. After completing training, expression of mir-133a, Runx2 and PPARγ on bone marrow were measured RT-PCR. The statistical analysis was performed using Kruskal-Wallis test with significance level of P
