What this trial measures
- Maximal Exercise: Maximal oxygen consumption will be evaluated using cycle ergometry or treadmill to exhaustion as described in the Integrative Physiology Laboratory at each testing visit.T1 (baseline), T2 (18-24 weeks), and T3 (12 months)
Investigators will use a graded protocol, starting at 50 watts followed by 30 watt increments every 2 minutes. Subjects will be connected to a breath-by-breath metabolic system (Cosmed, Italy) for measurement of VO2peak. A maximal effort will be defined as fulfillment of three of the following criteria: 1) A plateau in VO2 with an increase in work rate defined as an increase in VO2 of less than 50 ml/min; 2) A maximal HR within 10 beats of predicted maximal heart rate; 3) A respiratory exchange ratio of greater than 1.15; 4) No increase in heart rate with an increase in work rate (less than 3 beats); or 5) A rating of perceived exertion of 18 or greater on the Borg scale. These criteria are according to and consistent with the AHA exercise testing guidelines and performed regularly in Dr. Phillips' and Dr. Durand's laboratory groups59, 62-66.
