N/A gait and balance in older adults. Intervention 1: Intervention group 1: single-task gait and balance training This group will receive 6 weeks of balance training, 3 sessions per week. Each session will take 40-60 minutes and each exercise will repeat 5-8 times. Each exercise takes 30 seconds, with a 15-second rest between exercises. Intervention 2: Intervention group 2: dual-task gait and balance training This group will receive 6 weeks of balance training concomitant with a cognitive task (including naming, remembering and backward counting) , 3 sessions per week. Each session will take 40-60 minutes and each exercise will repeat 5-8 times. Each exercise takes 30 seconds, with a 15-second rest between exercises. Intervention 3: Control group: without intervention This group will receive no intervention during the 6-week period of the trial.
