Modulation of the ageing process in the rat

Abstract
Extended studies on the modulation of the ageing processes in the rat by physical exercise and food restriction - Monika Skalicky (University of Veterinary Medicine, Vienna)
The elderly part of the population grows both in numbers and age, which increases the prevalence of chronic degenerative diseases. Life-long keeping of physical fitness and avoidance of overweight are important for preventing a number of age-related diseases. An active life-style also increases life expectancy. Results from studies on animals agree with these findings from population studies. The mechanisms behind the beneficial effects of physical activity and avoidance of overweight are, however, largely unknown.
This project aims at extending from previous projects the analysis of the effects of life-long physical exercise and food restriction on the physiological ageing processes in the male rat from the age of 5 to that of 23 months. Since rats with free access to food grow obese with ageing, food restriction will be used as a model for avoidance of overweight.
In the previous studies we found that physical exercise preserved certain nerve cells in the brain and kept spontaneous activity in an open field setting at a more active level. For this activity also food restriction was beneficial. Now these studies are extended with tests on learning and memory.
