Arm && Interventions

Group	Intervention	Description
Loaded Walking High	Loaded Walking High	Walking on a treadmill while wearing a 30% body mass load with the weight placed at the high-back
Unloaded Walking	Walking	Walking on a treadmill without wearing a pack
Loaded Walking Mid	Loaded Walking Mid	Walking on a treadmill while wearing a 30% body mass load with the weight placed at the mid-back

Primary Outcome Measures

Name	Time	Method
Increased muscular jerk	Upon completion of 3 miles of walking, an average of 45 minutes	Jerk will be measured using accelerometers placed at the torso and ankle
Change in Oxygen Consumption	Upon completion of 3 miles of walking, an average of 45 minutes	Oxygen consumption will be measured using indirect calorimetry
