ABSTRACT
The importance of exercise in the elderly is widely recognized, but data on performances and drop-out in short running contests are lacking. This hinders stimulation and coaching of elderly persons in active aging. The aim of the study was to determine age-related changes in running performance in the most popular Dutch road run, and how this is influenced by gender, training, and increased participation rate over the last decade. This is a retrospective analysis of 194,560 participants of a 15-km run from 1995 to 2007. Multiple regression analysis of running time by age, gender, and training was performed. Trends in participation were examined by chi-square tests and ANOVA. Trends in running time and speed were examined by t tests. With aging, running time increased with 0.20% per year (P < 0.001). Running time was on average 13% (P < 0.001) shorter in men than in women and was 15.7% (P < 0.001) shorter in participants who trained on a regular basis. Decline in performance with age was 5.9% larger for men than women (P < 0.01) and 4.5% larger for trained than untrained participants (P < 0.01). Over the last decade, participation numbers increased most for elderly (≥60 years) and female participants, mean running performance declined with 9.9% (P < 0.001). Drop-out number was low at all ages (0.13-0.29%). It appears that aging has only minor negative influences on running performance, which can even be attenuated by training. Our data suggest that exercise by means of running is a safe and rewarding option for improvement of healthy and active aging.
