Pedometers are cheap and easy to handle devices that have proven their accuracy to measure the number of steps taken during a time period (day or week). However, at lower walking speeds and if used by obese persons the accuracy of several pedometers decreases significantly. Pedometers are not able to record the intensity of daily physical activity. In addition, the number of steps depends on age, gender, body weight and season. Nevertheless, monitoring of daily physical activity with a pedometer may be an effective method to enhance the daily physical activity of selected subgroups. For instance, subjects with an increased risk of obesity or hypertension, sedentary patients with diabetes mellitus type 2, patients with coronary heart disease and cancer patients can more easily be stimulated to become physically active and meet healthy living standards. Pedometers combined with existing effective counseling methods may be an effective strategy for many health care providers for adoption and enhancement of healthy lifestyles by sedentary patients.

Since 1980, More Exercise for Seniors (MBvO in Dutch) has provided a number of special physical activities for the elderly. The aim is to improve social participation and integration, and to prevent a need for care. Despite the fact that MBvO has been active for more than 25 years, and weekly 300,000 people participate in gymnastics, swimming, dancing, etc, no effect on fitness and health has been proven to date. The study was carried out in two regions: Drenthe and Zuid-Holland. Using the GALM (Groningen Active Living Model) method, 4600 independently living people aged 65 years and older were asked to participate in a motor fitness test. Of the 721 people who participated, 386 (the least fit) were invited to take part in the study. They were than randomly divided into an experimental and a control group. The experimental group did gymnastics once or twice a week. The control group received a health educational program. Assessments were carried out at pretest and posttest (10 weeks). In the groups offered MBvO gymnastics once a week, no effects were found on subjective health, physical performance or quality of life and only minor effects on physical fitness. In the groups offered MBvO gymnastics twice a week, some beneficial quality of life effects were found in the least physically active people at baseline. It is recommended that the frequency and intensity of the regular MBvO gymnastics should be increased, to emphasize the importance of health education, and that relatively inactive and older individuals (70+) should be recruited.

The assessment of fitness is a component of a national project aimed at the enhancement of physical avtivity among sedentary older adults, aged 55-65 year in the Netherlands. Deterioration in physical functioning may be improved through an exercise programme. Research showed that enhancement of physical activity results in improved fitness, increased functional ability and health-related quality of life. Scientific results of the association between exercise and physical fitness in older adults is not sufficiently evidence-based in the Netherlands. In order to support health policy interventions 5.584 fitness tests of sedentary older adults were analyzed. The fitness was assessed by the Groninger Fitnesstest for Elderly (GFE). The analysis of physical fitness in sedentary older adults showed a lower fitness status among the age group 55-65 of age and women. Health risk factors such as overweight and having a chronic disease explained 88% of the variance between a low fitness and a high fitness profile.

Background: In ageing populations fear of falling is an important issue. International studies and collaborations require scales suitable to more cultures. Scales developed in one culture require adaptation and additional investigation of psychometric properties for use in other countries., Objective: To investigate the psychometric properties of a Dutch version of the Activities-specific Balance Confidence scale (ABC-NL) and whether adding questions about complex/dual tasks improves the discriminatory power., Method: Subjects were 106 men and 140 women aged 65-92 years. Measures were the 16-item ABC-NL and seven additional more complex items, fall history, general and physical self-efficacy, a functional reach test and a balance platform test., Results: The ABC-NL had a weak ceiling effect. Internal consistency (Cronbachs alpha) was high. The relationship between ABC-NL and physical self-efficacy was significantly stronger than between the ABC-NL and general self-efficacy. Relationships with performance-based measures of balance were moderate. Differences between fallers and non-fallers and between activity avoiders and non-avoiders were significant. Adding questions about complex tasks hardly improved discriminatory power, reliability and validity., Conclusion: Psychometric properties of the ABC-NL were satisfactory. Further research is needed for use in high-functioning older persons.
