Background: Valid and reliable field tests for measuring physical fitness and different health parameters is an important matter for evaluating effects of exercise interventions.
Purpose: The aim was to study different test parameters such as aerobic capacity, strength, perceived health and life style habits, such as physical activity, in a physical activity intervention for elderly people.
Method: 117 old-age pensioners (99 women and 18 men). Their mean age (yrs) and BMI (kg/m2 ) was 74 and 26 for the women and 73 and 25 for the men, respectively. Different aerobic, strength and balance tests were measured. Guided physical activity (nordic walking, strength training, aqua gymnastics), were given 45-60 min, 2 times/week for 8-12 weeks. Perceived exertion ratings during the exercises were moderate and/or strong.
Results: Significant changes (p< 0,05) were seen between pre- and post tests regarding all physical tests except the balance test for men. Even the perceived physical and mental health significantly improved. The mean values for questions concerning self reported inactive/active life style, including sedentary time, were changed to a more active life style.
Conclusion: 8-12 weeks of guided physical activity can improve several physiological parameters which are positively correlated to decreased risk of numerous diseases. More research is needed to develop reliable and valid field tests for physical capacity and different health parameters.
