Eleven older adults (49-66 years) participated in 15 weeks (60 sessions) of endurance walking. A training intensity of approximately 65% maximum heart rate was determined (Karvonen method), for each subject. The training resulted in improved cardiorespiratory fitness as evidenced by a significant 19.2% mean increase in maximal oxygen uptake (ml/ kg-min.), and a significant bradycardial response of heart rate during submaximal walking. An insignificant change in mean absolute body weight was observed, however, subjects lost significant amounts of subcutaneous body fat as demonstrated by a. decrease in percent body fat and sum of six skinfold measurements.The male subjects showed more pronounced improvements in their fitness as evidenced by a greater weight loss, lower resting heart rate, improved oxygen uptake and maximal ventilation. These benefits were possibly due to a greater walking velocity and total mileage attained by the male subjects. This infers that the men were able to exercise at a higher intensity and duration than the females.
