Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Exercise Endurance Time to Maximum Tolerance
Time Frame: Maximum exercise endurance in minutes, for both treatment arms. Two 4-hr study visits, 1 week apart. Endurance endpoint will be evaluated during a single 4-hr period on Study Visit 2. Each exercise test will be separated by a 1.5 hr rest period.
|
Endurance measured on cycle ergometer at predetermined constant work rate.
Subjects will exercise to their limit of tolerability (max effort).
|
Maximum exercise endurance in minutes, for both treatment arms. Two 4-hr study visits, 1 week apart. Endurance endpoint will be evaluated during a single 4-hr period on Study Visit 2. Each exercise test will be separated by a 1.5 hr rest period.
