Introduction: The objective was to evaluate the effects on aerobic endurance of a physical exercise program based on Nordic walking for the improvement of physical condition in older adults. Methodology: The population consisted of 29 subjects, the results of a twelve-week Nordic walking program, with a minimum of two weekly sessions. Two measurements were carried out; a previous and a subsequent one, through an effort test. Results: The population showed improvements in the intensity reached during the stress test. Likewise, significant increases (p<0.05) were observed in the variables oxygen consumption and heart rate. Conclusions: The Nordic walking program has increased the physical condition of our population, finding improvements at the cardiorespiratory level in both men and women.
