In very old and/or frail older people living in long-term care facilities, physical inactivity negatively affects activities of daily living. The main reason to assess older adults' perceived fitness is to establish the relation with their beliefs about their ability to perform physical activity adjusted to daily tasks. The Self-Assessment of Physical Fitness scale was developed to address these needs. The aim of this study was to estimate the test-retest reliability and construct validity of the scale. 76 elderly people (M age = 86.0 yr., SD = 6.3) completed the test. Cronbach's a was .71. One-week test-retest reliability ICC's ranged from .66 (SAPF aerobic endurance and SAPF balance) to .70 (SAPF sum score). Concurrent validity with the Groningen Fitness Test for the Elderly was fair to moderate. Despite the limited number of participants (N = 76), results suggest that the scale may be useful as an assessment of perceived fitness in older adults.

OBJECTIVES: In health evaluations, physical activity (PA) and cardiorespiratory fitness (maximal oxygen uptake [VO2max]) are important variables. It is not always possible to assess both of them. If the association between self-reported PA and VO2max was strong, it would be possible to use the information on PA to make assumptions about VO2max and vice versa. However, little is known about this relation, in particular among women at high risk for cardiovascular disease. Our aim was to study the association between self-reported PA (Short QUestionnaire to ASses Health enhancing PA) and fitness (determined using the Siconolfi step test) among sedentary women in a multiethnic population.STUDY DESIGN AND SETTING: Participants were sampled from an exercise program for sedentary women (The Netherlands, 2008-09). Linear regression was performed with VO2max (dependent variable) and self-reported PA (independent variable); covariates were age and body mass index.RESULTS: One hundred ninety-seven women from different ethnic backgrounds were included. No significant association was found between VO2max and PA (R(2) = 0.60).CONCLUSION: A poor association was found between self-reported PA and estimated VO2max. Hence, PA and VO2max represent two different aspects of health in sedentary women and cannot be used interchangeably. This should be taken into account when evaluating health promotion interventions or when making health risks statements in sedentary women in a multiethnic population.
Objective: Health beliefs of overweight adults who did and did not enter an exercise program were compared to identify possible factors that hamper people to increase physical exercise. Method: Participants (n = 116, 78 women and 38 men) were overweight adults without comorbidities. Self-report instruments examined the burden of suffering, beliefs related to physical exercise and obesity, somatic complaints, and obesity-related quality of life of new participants of exercise programs versus sedentary non-exercisers. Results: Mean BMI of exercisers was and of non-exercisers was 34.6 (7.0) and 32.8 (5.8) respectively. The exercisers were more often female, had fathers with less overweight, and considered overweight a more serious health problem. Fear of injury was higher and perceived health benefits were lower in the non-exercisers, who also more often attributed their overweight to physical causes and believed overweight to be irreversible. Body weight, age, education level, somatic complaints, and quality of life of the groups were comparable. Conclusion: With respect to health beliefs, overweight non-exercisers reported more fear of injury and perceived their overweight as more irreversible than exercisers. Considering these factors in intervention and public health promotion may help overweight sedentary people to start physical exercise.
