RESUMO
The purpose of this study was to propose useful ADLs (activities of daily living) and scales to estimate ADL ability on community older people from the viewpoints of aging, physical fitness level, and interrelationship among ADL. The survey constructing of 15 ADL items and physical fitness test of Ministry of Education, Science and Culture were carried out on 458 older people. Each ADL item was constructed with 3 level scales.<BR>As the results of this study, the following 12 ADLs were proposed as useful ADL items; in the locomotion domain, jumping across a ditch, walking, running, up and down stairs, and transfer; in the manipulation domain, taking bedding in and out, buttoning a shirt; in stability domain, standing in the bus or train, dressing while standing (trousers), standing on one foot with eyes open; in the posture-change domain, sitting up, standing up from the floor. These items were significantly related to age and physical fitness elements contributed largely to achievement of each ADL. Since significant high correlation was found between the index using 12 ADL items and that using 15 items, it is considered that the 12 items scale can account for the variance corresponded enough to that of 15 items scale, and that the new index is practical and simple.<BR>In further research, it will be required to examine validity of each ADL item and index by using more large sample, and to clarify the relation to various factors influenced to ADL ability level.
RESUMO
The purpose of this study was to examine sex differences in subjective symptoms of fatigue (SSF) in high school and college students by considering the relationship between subjective feeling of fatigue and life habits.<BR>A questionnaire on SSF (54 items), dealing with subjective feeling of fatigue and life habits (frequency of exercise, going to sleep, waking in the morning and physical condition) was administered to 5622 healthy students aged 15-20 yr, and data of 5335 properly completed questionnaires was analyzed.<BR>The following was determined :<BR>1) Sex differences were confirmed in most SSF items. SSF complaints for females was generally higher than that of males.<BR>2) The relationship between SSF and the age was low in both sexes.<BR>3) Subjective feeling of fatigue is somewhat related to SSF.<BR>4) The going to sleep last night influence on SSF was different in both sexes and related largely to the next day SSF in males.<BR>5) Waking this morning and today's physical condition are related to SSF in both sexes.<BR>6) In males, the influence of exercise habits on SSF regarding drowsiness is relatively large.
RESUMO
A study was performed to examine sex and age differences in physique and physical fitness and the sex differences in the change of these parameters with age, and to clarify the relationship between the amount of exercise and fundamental physical fitness in 326 healthy elderly individuals over 60 years of age.<BR>A total of 22 variables consisting of 9 items concerning body linearity, quantitative growth, circumference growth and posture, and 13 items representing 4 domains (muscular, joint, neural, and cardiorespiratory functions) were selected. The exercise performance index (EPI) was calculated as the product of frequency and duration (yr) of exercise. The sex and age differences in physique and physical fitness were examined using two-way ANOVA (sex × age group) . Post hoc tests using Ryan's procedure were carried out when the main effect of these factors proved significant. To examine the characteristics of changes in physique and physical fitness with age, Pearson's correlation coefficient was calculated, and linear regression analysis [test item was the dependent variable (X) and age was the independent variable (Y) ] was applied. Then significant differences in the regression coefficient and intercept between males and females were examined. Furthermore, curved-line regression analysis was executed for the above variables. Applying principal component analysis for 13 physical fitness items, the first principal component was interpreted as fundamental physical fitness for performance, and the above analysis was applied to the fundamental physical fitness score (FPS) . To examine the relationship between EPI and FPS, the difference in FPS among the three EPI groups was examined using analysis of co-variance (ANCOVA) with age as the co-variable.<BR>The main findings of this study can be summarized as follows.<BR>1. With regard to physique, males showed greater body linearity, and females had more skinfold. Sex differences in circumference growth were not as significant as those in body linearity and quantitative growth. Changes in physique with age were greater in females than in males, the change becoming obvious in individuals over 80 years of age.<BR>2. With regard to physical fitness, males had superior muscular function and vital capacity, while females outperformed males in standing-reach. However, there was little sex difference in neural function. The trend for deterioration in physical fitness with age differed between the sexes among 4 domains of physical fitness. For example, in males muscular, neural, and joint functions deterioration significantly with age, while in females, all physical fitness variable did so. In addition, the age-related trends of deterioration in muscular function (grip strength and vertical jump), cardiorespiratory function (duration of breath-holding and vital capacity), and neural function (stepping) were differed between the sexes.<BR>3. The FPS was higher in males than in females. However, FPS decreased significantly with age in both sexes.<BR>4. It was inferred that among active and healthy elderly males and females who exercised regularly, FPS was not influenced by EPI.
RESUMO
A study was conducted to examine sex differences in subjective symptoms of fatigue in men and women with reference to the experience of awareness and cognitive appraisal based on symptom of fatigue content. A total of 54 questionnaire items were administered to 730 people (290 men and 440 women) . The subjects indicated whether or not they were aware of the content, and to what degree the content of the question for each item was important. Sex differences in the response to the ratio of awareness and the degree of importance were then. The mean importance scores for subjective symptoms of fatigue in men and women were 3.9-5.4 and 4.5-5.6, respectively. It was found that a majority of the men and women showed awareness of each item. A significant difference was recognized in the factor of awareness in all items as a result of two-way ANOVA of the degree of importance by which the presence of awareness and its sex difference were assumed to be factors, and those who were aware deemed the degree of importance high. On the other hand, the 28 items for which a significant sex difference was recognized showed a high value, and there was a marked content of Languor, Loss of Vigor, and A Feeling of Impatience and Physical Disintegration in women. In the same items, it was inferred that persons who were more aware than the persons who were not aware regarded subjective symptoms of fatigue as important. Most items in which a main effect of sex was recognized were content of Loss of Vigor and a Feeling of Impatience and Physical Disintegration. It was thought that women considered these symptoms more important than men. The sex difference in symptoms of fatigue was inferred to be due to the difference in the level of acknowledgment based on experienced knowledge.
RESUMO
The purpose of this study was to investigate the relationships of fundamental physical fitness (FPF) and health-conditions, activities of daily living, and food habits in elderly women.<BR>A total of 338 women aged 60 to 89 years were the subjects for this study. Fourteen tests were selected from 4 physical fitness domains of muscle function, joint function (flexibility), neuromuscular function and lung function, considering the validity, safety and convenience of tests. To measure the above-stated living conditions, a questionnaire consisting of 30 items was constructed. Principal component analysis was applied to the correlation matrix, which was calculated from physical fitness variables. The first principal component could be interpreted as the FPF factor, since it correlated significantly with all physical fitness variables and showed the greatest contribution (about 36%) to total variance. Statistical techniques of contingency coefficient and theory of quantification I were used to determine the influence of the above-stated living conditions to FPF.<BR>It was inferred that each living condition influences FPF as a composite factor, and the elements of exercise habit, the existence of the trouble caused by past disease and injury, bedtime and age have greater influence on the decline of FPF. Fundamental physical fitness showed a decreasing trend with age, but the continuous exercise enforcement on one day or more a week, seemed to be effective in postponing the decline of FPF related to age. Further, it was inferred that influence of each living condition to FPF differs in the 60 and 70 age levels.
