The aimed to evaluate the effects of low and moderate-intensity aerobic exercise on psychological well-being (PWB) and quality of life (QoL) among older people. Forty-five male Iranian adults aged 65–80 years were selected according to the eligibility criteria and randomly assigned to a low-intensity group (LIG) (40–50% of maximum heart rate), moderate-intensity group (MIG) (60–70% of maximum heart rate) and control group (CG). The exercise protocols consisted of 12 weeks of aerobic exercise (two sessions per week). Psychological well-being and QoL were assessed through the Ryff's Psychological Well-being Scale and the World Health Organization QoL Questionnaire. The statistical analysis for psychological well-being indicated that a significant main group (between-group) (F = 11.777, p < 0.001, ηp2 = 0.359), time (within-group) (F = 58.983, p < 0.001, ηp2 = 0.584) and interaction effect (group × time) (F = 20.146, p < 0.001, ηp2 = 0.490) for PWB total score. Bonferroni post-hoc tests revealed that the PWB total score in the MIG group was more significant than both LIG (p = 0.003) and CG (p < 0.001). Results for PWB components including self-acceptance, positive relationships with others, autonomy, purposeful life, and environmental mastery revealed no significant differences (p > 0.05). While there was a significant difference between the groups for personal growth component. Bonferroni post-hoc tests revealed that the personal growth in the MIG group was more significant than both LIG (p = 0.028) and CG (p < 0.001). Result for QoL indicated significant differences for the main group (F = 13.277, p < 0.001, ηp2 = 0.387), time (F = 25.533, p < 0.001, ηp2 = 0.378) and interaction effect (F = 9.992, p < 0.001, ηp2 = 0.332) for QoL total scale. Bonferroni post-hoc tests revealed that the QoL total scale in the MIG group was more significant than both LIG (p = 0.003) and CG (p < 0.001). Results for QoL components including Physical health, Social relationships, Health environment revealed no significant differences (p > 0.05), while there was a significant difference between the groups for the Psychological health component. Bonferroni post-hoc tests revealed that the Psychological health in the MIG group was more significant than both LIG (p = 0.009) and CG (p = 0.002). Therefore, aerobic exercise improves PWB and QoL in older adults, moderate-intensity exercise seems to produce higher benefits than low-intensity, demonstrating a positive dose-response relationship.

Abstract:The purpose of present research was to investigate the effect of low and moderate intensity aerobic exercises on sleep quality in older adults. The statistical sample included 45 volunteer elderly men with age range of 60-70 years old that divided randomly in two experimental groups (aerobic exercise with low and moderate intensity) and one control group. The maximum heart rate (MaxHR) of subjects was obtained by subtracting one's age from 220. Furthermore, based on aerobic exercise type (40-50% MaxHR for low intensity group and 60-70% MaxHR for moderate intensity group) the target MaxHR was calculated for each subject. The exercise protocol consisted of 8 weeks aerobic exercises (2 sessions in per-week) based on Rockport one-mile walking/running test and the control group continued their daily activities. All subjects in per-test and post-test stages were completed the Petersburg Sleep Quality Index (PSQI). Results in post-test stage showed that there were signi cant differences between control and experimental groups in sleep quality and its components (P<0.05). Also, the Tukey Post Hoc showed that the moderate intensity group scores in sleep quality and its components were better than other groups (P<0.05). Finally, the low intensity group scores were better than control group (P<0.05). Generally, the present research showed that the aerobic exercises with moderate intensity have a positive and signi cant effect on sleep quality and its components. Thus, based 10MEDICINSKI GLASNIK / str. 9-17 on these  ndings, the moderate intensity aerobic exercises as a useful and medical method for improve the sleep quality among community older adults was recommended.

Background/aims Basic movements of Azeri dance as an intervention may have an impact on the physical and mental status of people with Parkinson's disease. The aim of this study was to assess the feasibility and efficacy of basic movements of Azeri dance on the balance and static posture of a person with Parkinson's disease. The effects of basic movements of Azeri dance on quality of life, quality of sleep and the performance in activities of daily living were reported before and after the intervention. Methods In this single-subject experimental ABA design, a 64-year-old man with a 4-year history of Parkinson's disease was selected. The outcome measures consisted of the Functional Reach Test, Timed Up and Go Test, qualitative static posture analysis, Short Form Health Survey, Modified Barthel Index and Pittsburgh Sleep Quality Index. Results An increasing trend in balance from the initial baseline stage through to the end of the intervention stage was found. Static posture analysis showed that the patient's posture improved qualitatively. His quality of life score changed after the intervention; however, his sleep quality and activites of daily living scores did not change. Conclusions Basic movements of Azeri dance are useful in the rehabilitation of patients with Parkinson's disease who have balance issues and postural instability, but further research is warranted.
