Abstract

The purpose of this study was to examine the effects of 8 weeks of resistance exercise on gait-related abilities and the differences in age groups to provide reference materials for application of training by age group. Subjects in their 30s, 40s, and 50s were recruited and subjected to a lower extremity exercise, in which the intensity gradually increased three times a week for eight weeks. The gait-related variables, torque at 0.18 sec, acceleration time, and torque at 30°, were assessed through isokinetic tests before and after the 8-week training. The torque at 0.18 sec showed a significant increase in the 50s group. There was no significant difference in acceleration time according to time and group. The torque at 30° showed a significant increase in the 30s group. In conclusion, 8 weeks resistance training can increase neuromuscular activity in adults in their 50s group, and changes in training variables are needed to increase torque at 30° that affects knee stabilization in adults over 40s group.
