تأثیر تمرینات ترکیبی (قدرتی و کششی) بر قدرت و دامنه حرکتی اندام تحتانی سالمندان

Objectives: Increasing age lead to many changes in motor assignments. Impairment of motor functions in elderly ceases the individual's inability in performing everyday tasks and activities. The aim of this study was to evaluate the effect of the combined training program on strength and range of motion of the elderly men. Methods & Materials: This study was quasi-experimental and participants included healthy elderly men (age 65/64 ± 4/95) in the Rasht. This study was conducted on 22 healthy men that have inclusion criteria and were selected by using convenience sampling. The maximum isometric force of the muscle groups in the lower extremities and range of motion was measured by a hand held dynamometer and a goniometer, respectively. The tests were conducted before and after training. The data were analyzed using descriptive and analytic statistics by spss version 16 software (At a significance level of p≤0.005). Result: The results showed that combined training for 8 weeks in compare to the control group have a significant effect on the strength of dorsi flexors (p = 0.001), plantar flexors (p = 0.002), hip flexors (p = 0.001), hip extensors (p = 0.013), hip adductors (p = 0.002), hip abductors (p = 0.001) and hamstring strength (p = 0.029) but has no significant effect on the strength of the quadriceps (p = 0.375). They also have a significant effect on the range of motion of the dorsiflexion (p = 0.002), plantar flexion (p = 0.019), hip abduction (p = 0.001), the hip adduction (p = 0.001), and hip extension (p = 0.012) in elderly men but does not have a significant effect on range of motion of the hip flexor (p = 0.086) and range of motion of the knee flexor (p = 0.336). Conclusion: It seems that combined exercises (stretching and strengthening) could effect on some range of motion and muscle strength of elderly.
