Patients with Mild Cognitive Impairment (MCI) demonstrate inadequacy in compensatory techniques and lacking motor control while falling; hence it appears that cognitive and motor deficiencies are inter-related. The aim of this study was to investigate the progressive dual-task effects on motor performance, cognitive status and fall risk between older adults.
Subjects and This study is semi experimental with pre– and post-test design. The subjects were selected from community dwelling elderly adults with mean age of 75.65 y (range, 65–90). Both groups (20 with MCI and 20 Healthy) participated in 12 weeks of intervention with progressive dual-task training, which entailed sitting, standing and transforming practices.
Examinations after 12 weeks showed that intervention caused improvements in cognitive status, postural control, and fall risk in both older adults with and without MCI. The MCI group experienced more positive changes in cognition, while the normal group had the most evident effects in fall risk and performance in Functional Reach (FR) test.
This finding supports the previous results which implied the positive effects of dual-task training on cognitive variables are associated to biological variations which arise during exercise training. We also suggest that the physical benefits of progressive dual-task training (e.g. flexibility) are overriding the cognitive changes. In future research, the pathophysiology and further clinical implications should be investigated.

The aim of this study was comparing the mental health and its subscales between elderly men in athletes, active and passive groups. Therefore we have taken 150 elderly men in three groups of athletes active and passive and proceed to complete questionnaires. This is a correlation study and for comparing the mental health we have chosen the GHQ-28 questionnaire. Also to assign aging people in two groups of active and passive, we have used the Yale physical activity questionnaire and beacke questionnaire and also the athletes aged group has been separately selected from the veteran's soccer teams above 60 years. For comparing the group's mean we have used ANOVA. The results of this study revealed that there is a significant difference between three groups in physical activity levels, mental health and it's two subscales as depression symptoms, and social function (P<0.01), Also there was a significant difference between active and passive groups and between athletes and passive groups in physical symptoms, and anxiety and sleep disorder subscales (P<0.01), but the difference was not significant between the athletes and active groups. CONCLUTION: The results of the study suggest that adapted physical activity programs to the structural and psychological characteristics of elderly men can improve their mental health and lifestyle as much as their physical health.

This study aimed to assess relationship between fundamental movement skills (locomotor and object control) and level of physical activities (organized and sedentary). Role of body mass index (BMI) was also examined as a moderator variable. The population of study consisted of 6 – 12 years old schools students in Qazvin city، which 116 of them were selected randomly as sample of study. Fundamental movement skills were tested by gross motor development test (TGMD-2) and daily activities were assessed by last year activities inventory. For examining body mass index (BMI)، height and mass of participants tested. Spearman correlation used to identify relation between fundamental movement skills and daily activities. Based on study results، total fundamental movement skills correlated positively to organized activities (r=0/560) but no correlation with sedentary activities was shown (r=0/380). Study revealed that children with higher levels of organized activities have higher proficiency at fundamental movement skill but high levels of sedentary activities have no significant effect on these skills. Moreover، over-weight and higher than normal levels of BMI in children restricts their participation in physical activities. Since participation in PE class and programs play an important role in motor skills development of children، organized activities setting by parents and physical educators have excellent importance.

This study aimed to investigate the effects of these methods on quality of life among demented elderly men. In the present study which used a semi-experimental method، 80 elderly men aged from 60-88 years old were selected randomly (mean age=70/94) and divided into three experimental (Group yoga، multi-sensory stimulation and combined) and on control group. The results showed that there were significant differences in quality of life and its four domains in pre-posttests between three experimental groups. The combined group which exploited from both types of intervention had most improvements in scores of quality of life. Furthermore، yoga was more effective than multi-sensory stimulation in physical domain، while multi-sensory stimulation had more positive effects in environmental domain between demented elderly men. Overall، engaging demented elderly people in environments and activities which are high in diversity and frequency of stimuli can significantly help them from psychological، physical and social perspectives. The findings of this study can be applied in designing and practicing the health promotion programs for demented elderly people.
