Supervised combined endurance and resistance training (CERT)
Subjects will undergo up to 18 supervised sessions of a structured exercise program of combined endurance and resistance training (CERT). Supervised CERT will occur for 3 days/week, approx. 1 hr per session. Endurance training will start at 15 minutes and progress to 30 minutes of cycling on a stationary recumbent bicycle at 65-85% of heart rate reserve by week 3. Resistance training volume and intensity (baseline determined from strength tests) will progress over the first four sessions to 3 sets of 8-12 repetitions to volitional fatigue for 8 movements, with alternating upper-body and lower-body movements during the session. Progression will be incorporated throughout the trial for both endurance and resistance training to maintain relative intensity.
Delayed supervised combined endurance and resistance training (CERT)
After a 6-week delay period (no-exercise control), subjects will undergo up to 18 supervised sessions of a structured exercise program of combined endurance and resistance training (CERT). Supervised CERT will occur for 3 days/week, approx. 1 hr per session. Endurance training will start at 15 minutes and progress to 30 minutes of cycling on a stationary recumbent bicycle at 65-85% of heart rate reserve by week 3. Resistance training volume and intensity (baseline determined from strength tests) will progress over the first four sessions to 3 sets of 8-12 repetitions to volitional fatigue for 8 movements, with alternating upper-body and lower-body movements during the session. Progression will be incorporated throughout the trial for both endurance and resistance training to maintain relative intensity.
