Baseline measures were taken for all participants. The control groups were told to resume normal activities. The strength-training group was taught three strength-training exercises by a physiotherapist (physical therapist). The exercises chosen were bilateral heel raises, bilateral half squats, and step-ups. Participants completed 8 to 12 repetitions of the exercise with good form until fatigue occurred (ACSM, 2002) to determine training loads. A training load was determined for each participant who then wore a backpack containing free weights while performing the exercises. Participants completed three sets of 8 to 10 repetitions of each exercise three times a week for 20 to 30 minutes each session for 6 weeks. The therapist visited the participants at home at the second and fourth week to evaluate the exercise techniques and to adjust the training load. Each participant received an exercise diary to record the weight used and the number of sets and repetitions of each exercise performed for each session. After the 6 weeks of training, both groups were told to resume normal daily activities for 12 weeks. Participants in both groups were assessed at 6 weeks and 18 weeks.
