 Forty-four individuals will be randomly assigned to one of two aerobic training programs on a treadmill. Both groups will performed three times a week for eight-weeks on alternate days. Half will run 40 minutes of continuous exercise at an intensity between 65-75 of maximum heart rate, and the remaining 22 will complete 21.5 minutes of interval exercise at an intensity between 90-95 of maximum heart rate, with recoveries between 50-55 of maximum heart rate. After each session both groups will complete eight strength exercises mainly including large muscle groups for two sets and 8-12 repetitions at an intensity equivalent to 60-70 of one repetition maximum controlled by perceived effort. Rest between sets will be kept between 60 and 90 seconds.
