The investigators proposed research will establish whether combining aerobic exercise with cognitive challenges is feasible and effective in community dwelling older adults with early signs of cognitive impairment.
To determine the effects of dual-task aerobic exercise training on community dwelling older adults with early signs of cognitive impairment. We will compare an exercise intervention (E-I) versus an exercise control (E-C) group. Each week, both groups will accumulate a minimum of 120 minutes of exercise (target 150 minutes) from community-based group classes (50 minutes of aerobic exercise) and also complete 45 minutes of beginner-level Square Stepping Exercise (SSE). The E-I group will also answer cognitively challenging questions while doing SSE (dual-task training). This study will determine whether a combined multiple modality (primary component being aerobic exercise) and dual-task exercise program is both feasible and effective for improving cognitive and mobility status, as well as vascular compliance, in older adults who may be at risk for cognitive and mobility decline.

Exclusion Criteria:
For 26 weeks, attend Canadian Centre for Activity and Aging combined classes (75-minute or 60-minute classes, 2 to 3 days/week) and also complete 45 minutes of dual-task gait training (15 minutes for 3 days/week or 22.5 minutes for 2 days/week)
Behavioral: Exercise Intervention
For 26 weeks, attend Canadian Centre for Activity and Aging combined classes (75-minute or 60-minute classes, 2 to 3 days/week) and also complete 45 minutes of gait training (15 minutes for 3 days/week or 22.5 minutes for 2 days/week). Note: no dual-task challenges during gait training
Behavioral: Exercise Control
Goal of 150 minutes of structured exercise/week; minimum of 120 minutes from CCAA classes/week. The 75-minute class includes: 5-minute warm-up; 25 minutes of AE (70-85% maximum heart rate); 5-minute cool-down; 20 minutes of strength training; 5 minutes of core strengthening; 5 minutes of balance training; and 10 minutes of stretching. The 60-minute program is identical except: 15 minutes total for all strength training (including core) and 5 minutes of stretching. Following CCAA classes, participants continue with dual-task gait training where they are required to walk on a special mat with a designated walking pattern (beginner level Square Stepping Exercise) while answering cognitively challenging questions.

Double support (seconds and % gait cycle time) under dual-task conditions
Initial double support occurs from heel contact of one footfall to toe-off of the opposite footfall. Terminal double support occurs from opposite footfall heel strike to support footfall toe-off.Total double support is the sum of the initial double support added to the terminal double support. It is measured in seconds (sec) and also expressed as a percent of the Gait Cycle time for the same foot. Measured with GAITRite system
Time frame: 12, 26 and 52 weeks
