Intervention: Combined Resistance and High-Intensity Interval training
Description: Completed 3 d/wk for 4 wks (2 d of Resistance Training (RT) and 1 d of High-Intensity Interval Training (HITT)). RT exercises were chest press, seated row,leg press, shoulder press, leg extension, and leg curl (3 total sets: 2 sets of 10 repetitions and a 3rd set to muscular exhaustion with a load equaling 75-85% of 1-Repetition Maximum(RM)). All exercises and sets were separated by 90-120 sec of rest. HIIT training was completed on commerical cardiovascular equipment and requires subjects to rate their perceived exertion on a scale from 1 to 10 (1= resting quietly, 5= a warm-up level, 10= an all-out exertion). Subjects warmed-up for 2 min at level 5 and increased their exertion each min for 3 min until level 9 is perceived and then recover at level 6 for 1 min. This pattern was repeated 4 times, where the 4th cycle subjects increased their last min of exertion to level 10, followed by 1-min recovery at the initial warm-up level 5.
