Adolescents' physical activity habits--results from a national health survey.

BACKGROUND: The MABAT Youth National Health and Nutrition Survey was conducted in Israel by the Ministry of Health and the Center for Disease Control. This article presents results of physical activity (PA) habits in Israel, in relation to recommendations by world health organizations. METHODS: Participants were 6274 adolescents, grades 7-12, enrolled in a cross-sectional, representative, school-based survey. Sufficient level of PA was defined as any moderate and vigorous level of PA that adds up daily to 60 min/day. Light PA was considered to be an insufficient level of PA. RESULTS: Only 10.5% of the participants reported performing sufficient PA. Large gender differences were found, with 17.7% of boys versus only 4.6% of girls meeting the guidelines. CONCLUSIONS: Results highlight the need to develop programmes for school children in Israel to promote PA. Such programmes have been initiated in many countries that have a large percentage of adolescents with a sedentary lifestyle.

Habitual physical activity is a meaningful predictor of well-being in mid-life women: a longitudinal analysis.

OBJECTIVES: To examine whether physical-activity patterns over a period of 4 years are associated with well-being. DESIGN: A sample of 399 women aged 50-60 years participated in the study. Measures included rate of physical activity and other life style behaviors, well-being, health status, and interpersonal stress. Sufficient and insufficient exercisers were identified, and the association of this dichotomy with well-being, along with the contribution of the other variables, was examined. RESULTS: The distribution of physical-activity patterns remained stable over the 4 years of the study, with 40% of the women exercising leisurely and 15-20% exercising vigorously four to seven times a week. Approximately 50% of the women were considered sufficiently active in terms of public recommendations. Random effects regression analysis revealed that sufficient exercise along with a low frequency of daily hassles, relatively few menopausal symptoms, and a low level of interpersonal stress significantly contributed to the variability of well-being. CONCLUSIONS: These data evoke the need for a better understanding of exercise behavior and its promising potential contribution to the well-being of middle-aged women.

The effect of a single aerobic training session on cognitive flexibility in late middle-aged adults.

Research has shown that aerobic exercise enhances cognitive function, specifically executive functions. This study examines the effect of acute aerobic exercise on cognitive flexibility - an executive function - in late middle-aged individuals. Fourteen men and 45 women aged 50 - 64, were randomly assigned to moderate exercise (60 % of heart rate reserve), moderately-intense (70 % of heart rate reserve) exercise, and movie-watching control groups after a maximal exercise test. Prior to and following the exercise or control sessions participants performed two cognitive tasks: the Alternate Uses assessing cognitive flexibility and the Digit Span Forward subtest from the Wechsler Adult Intelligence Scale - Revised assessing attention span. Results indicated significant improvement in Alternate Uses in the exercise groups but not in the control group. No group differences were indicated on the Digit Span. These results provide partial support for the benefit of acute aerobic exercise on cognitive flexibility.

The menopausal transition: does it induce women's worries about aging?

OBJECTIVE: This study examines whether patterns of worries about aging change in women during the menopausal transition. DESIGN: A population-based sample of 261 Australian-born women aged 45-55 years at baseline participated in a longitudinal study. Data were collected at baseline and in the 5th year of annual follow-up interviews. Measures included the Attitudes to Aging Scale which is based on a scale developed by Kaufert and Syrotuik and contained the six-item version which examines worries about specific losses. Menopausal status was determined by menstrual status as follows: late reproductive, early menopausal transition, late menopausal transition, and postmenopause. RESULTS: Data analysis carried out by cross-tabulation found that 36% of participants did not change their attitudes over the 5-year follow-up period, 30% became more worried and 33% became less worried and there was no significant difference between those who had or had not experienced the menopausal transition. There was no significant association between the scores on the Attitudes to Aging Scale and changes in the self-rated health, work status and marital status. CONCLUSION: The menopausal transition does not induce an overall increase in worries about aging.

Attitudes of middle-aged women to aging: contribution of the Reactions to Aging Questionnaire.

Attitudes to aging in mid-life have been found to be a predictor of health and well-being. The main purpose of the study was to assess the contribution of the Reactions to Aging Questionnaire (RAQ) to the understanding of middle-aged women's attitudes towards their aging. An additional purpose was to expand the existing information regarding the dimensions of the new version of the RAQ. Middle-aged Melbourne women (n = 381) were asked to complete the RAQ, in addition to another attitudes-to-aging scale (Worries About Aging). Factor analysis of the RAQ was used to explore its dimensionality, and frequencies of responses were used to assess the spread of response of both instruments. The factors extracted in the factor analysis of the RAQ were interpretable and meaningful in terms of emotions related to aging. They were also similar to the factors described by previous data. The RAQ was more effective in its distribution ability than the Worries About Aging Scale. With some modifications, the RAQ may be more informative than was the Worries About Aging Scale in its ability to assess emotions, opinions and beliefs associated with aging in middle-aged women.

Assessment of functional fitness among independent older adults: a preliminary report.

The goal of the present study was to develop a field test for assessing various components of daily activities among independent older adults. The test has 8 subtests of Coordination, Balance, Arms Strength, Upper Extremities Flexibility, Lower Extremities Flexibility, Agility, Legs Strength, and Walking Ability. Subjects were 252 volunteers whose mean age was 72.4 (+/-6.3) yr. A self-report daily functioning scale and a global health scale were also administered to a group. Analysis indicated test-retest reliability of approximately .8, and factor analysis yielded three factors interpretable and meaningful as domains of motor function, i.e., neuromuscular function, strength, and flexibility. Correlations of scores on the test with scores on the two self-rated scales of daily functioning and health, while controlling for age, were significant, suggesting the test measures skills that represent the main activities of daily functioning.

Primary visual memory of stroke patients.

This matched control group study assesses primary visual memory of stroke patients using the GEMAT visual-memory test. Primary visual memory of 29 stroke patients who scored 24 or more on the MMSE was compared with that of 33 age and sex-matched controls. Patients were recruited from physiotherapy outpatient clinics. Measured variables were the total time needed to complete the test (GTT) and the number of correct answers (GCA). Patients were slower (p < 0.01) and made more mistakes (p < 0.01) than controls. 'Young' (60-71) subjects made fewer mistakes (p < 0.01) than old subjects (72-89) and patients who scored 24-26 on MMSE were slower than patients who scored 27-30. It should be taken into consideration that stroke patients whose cognitive function is within a normal range of the MMSE might have impaired primary visual memory.

Exercise and the psychological state of institutionalized elderly: a review.

The present review examined the hypothesis that exercise facilitates psychological processes among institutionalized geriatric and psychogeriatric elderly persons. Studies of long-term psychogeriatric patients showed significant cognitive change following a period of moderate aerobic exercise. However, no lasting cognitive effect of long-term exercise was observed for those who became mentally or physically impaired in old age or who could not tolerate strenuous exercise. On the other hand, improvement in cognitive function was reported immediately following an exercise session among geriatric institutionalized patients. Neither long-term nor short-term exercise brought about changes in affect. Although most studies suffer serious methodological shortcomings, the common finding of improved cognitive function immediately following exercise suggests that physical activity does have some arousal effect on cognition in institutionalized elderly persons. More studies are needed to clarify the immediate versus long-term effect of exercise on psychological variables among institutionalized elderly as well as the relationship between physical fitness and cognitive change.

Pattern of psychological fitness as related to pattern of physical fitness among older adults.

The purpose of the present study was to investigate psychological fitness as well as physical fitness among late middle-aged normal men and women before, during, and after a 12-wk. physical activity program. Heart-rate of each subject was measured on a graded treadmill four times, and four psychological measures were taken: self-esteem, body-image, trait-anxiety, and well-being. Improvement of fitness was gradual and significant for both sexes, whereas no effects of time or sex were found on the first three psychological measures. Significant differences in pattern of change between women and men on well-being confirm previous findings that women report more depression and less satisfaction than men and thus are more sensitive to change.
