Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Exercise Session
Subjects will exercise on a treadmill for 1 hour at moderate intensity (i.e., 90% of the exercise intensity found to elicit their ventilatory threshold during the preliminary testing, which is equivalent to approximately 60% of their maximal predicted heart rate).
