Abstract

  Background & Objectives: With regards to the importance of health and Quality of Life improvement in the elderly in relation with physical activity and self esteem, the aim of this study was to determine the effect of programmed exercise on the self esteem of elderly residents in the nursing home of Rasht city in 2008.

  Methods: This study included a pretest and post test on 32 qualified samples. The Rosenberg self esteem scale were filled by them. Then, they attended a programmed exercise for one month. The scale was filled again by participants. The collected pre-test and pot-test data were analyzed using a-t-test SPSS software.

  Results: The average age of the participants was 73.53 (± 8.31). Most of them were widowed, 43.8% had no children, 87.5% were uneducated and the rest (12.5%) had a primary level of education. 37.2 of them had resided in the nursing home for less than one year and their average of residence was 1357±17.11 days. The source of income for 59.4% of participants was through children and relations. 27 persons (84.4%) had frequent visits with relations. 34.4% of them had a disease in history. There were significant correlations between number of children, marriage, education and job and number of previous jobs, gender job and education and number of previous job, visit frequency and education and time of the last visit. The correlation between sums of self esteem scores before and after the exercise was positive and significant and 22.81±4.84 Average of self esteem score before and after programmed exercise was 26.84±4.35.

  Conclusion: Regular exercise is effective in improving the self-esteem among the elderly and it can recommend to the elderly as a safe and cheap method.

Abstract

  Background & Objectives: Numerous studies have been conducted to assess the effects of acute resistance exercises on the structure and the function of heart, but little works done on effects of chronic resistance exercises. So, the objective of current study was to investigate the long term effect of regular exercises on cardiac function and oxidative stress.

  Methods: Forty male Wistar rats in the weight range of 250- 300 g were used in this study. They were divided in 2 following groups: The 3 months exercises test group and control group which remained without exercises. Regular resistive exercise was carried out according to the model proposed by Tamaki et al. Test group rats exercised for three months. Finally the hearts of 10 rats in each group were taken for homogenization, oxidative stress measurement and the other ten were examined for heart function. Malondialdhyde as an index of oxidative stress and superoxide dismutase, glutathione peroxides and catalase as an indicator of antioxidant capacity with special kits were specifically measured.

  Results: Regular resistive exercise didn't significantly affect the rats' weight, but heart weight in exercise group showed a significant increase (p<0.05). There was a significant decrease in heart rate in exercise group (p<0.05). Left ventricle contraction strength and coronary flow had a significant increase in exercise group in comparison with control group (p<0.05). There was not any significant difference in Malondialdhyde and antioxidant enzymes activity.

  Conclusion: This study showed that, heart efficiency had a significant improvement under effect of regular resistive exercise. Meanwhile, regular resistive exercise didn’t have any significant effect on oxidative stress and heart antioxidant defense capacity.
