Background and Aim: Much reserch has been done in recent years on the impact of resistance training on the physical function of the elderly people. In this study, the effect of  a 12 weeks combined exercise on P3NP, CAF and physical activity of elderly people was investigated.
Materials and Methods: The present study was experimental with a pre-test  post-test design. Twenty one elderly people were selected in a purposeful manner and randomly divided into two groups. The control group consisted of ten subjects and a combined training group (n = 11). Combined exercises consisted of three sets of resistance- speed training with intensity 60-50% of 1RM and 10-8 repetitions (10-13 seconds) with four-way walking in different intensities. Before and after the exercise, BMI, physical performance tests, and serum levels of P3NP and CAF indices were evaluated in all groups by ELISA method. ANOVAs tests with repeated measurements were used to determine variables changes within groups.
Results: The results showed that functional performance improved in the training group compared with the control group (p <0.05). Also, the combined exercise program did not have a significant effect on serum levels of P3NP and CAF (ρ = 0.146 and ρ =0.124).
Conclusion: The results of this study showed that performing resistance- speed exercise with walking in different directions could improves physical performance and might have showed down the process of decreasing neuromuscular quality in elderly people.
