Abstract
INTRODUCTION
Physical fitness is strongly associated with daily physical function, health, and longevity in older adults. Field-based tests may provide a reasonable alternative compared to advanced laboratory testing. Separating post-exercise test-scores from reactivity measurements requires sufficient test-retest reliability. Post-exercise test-scores with reliability-analyses of field-based fitness-tests in older adults are lacking. The present study aimed to examine the test-retest-reliability of some novel easily accommodated fitness-test-measurements and compare pre-test scores with post-exercise results in these tests along with other field-based fitness tests in older adults.
METHODS
Totally 1,407 community-dwelling-older-adults (69%-female), x̄=71.5±5.0 (65-84 years), performed twelve field-based-fitness-tests at pre-test-1, pre-test-2 and a post-test after an 8-week-exercise-period (twice weekly 1 hour of combined strength and aerobic training). T-tests, intra-class correlation, limits of agreement, standard error of measurement and coefficient of variance were performed between pre-1-and-pre-2-tests, and Repeated-Measures-ANOVA and partial eta squared effect size for post-exercise differences, for men and women in five-year age groups ranging from 65 to 84 years.
RESULTS
Between pre-1 and pre-2-tests a significant difference was noted in some of the novel fitness-test-measurements, but generally not e.g., in isometric trunk-flexion and step-up-height on either leg among all sex and age groups. In most of these novel fitness-test-measurements, no significant differences occurred between the two pre-tests. Examples of results from the pre-2-test to the post-test were: isometric-trunk-flexion-45°-endurance and isometric-trunk-extension-endurance improved significantly for both sexes in age groups 65-74 years. Women, but not men, improved the maximal step-up-height for both legs in most age-groups. The speed in the 50 sit-to-stand improved significantly for most age-groups in both sexes. Six-min-walk-distance improved significantly for most age-groups in women but among men only in 65-69 years. In the timed-up-and-go-test, significant improvements were seen for all age-groups in women and in men 70-79 years. No post-exercise improvements were generally observed for grip-strength or balance.
CONCLUSIONS
In most of the novel fitness-test measures no significant difference was noted between the two pre-tests in the assessed sex and age groups. Results after the-8-week-exercise-period varied between sex and age-groups, with significant improvements in several of the twelve studied fitness-tests. These findings may be valuable for future projects utilizing easily accommodated physical fitness tests in older adults.
期刊介绍:
In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
