Alterations in Gait, Strength, and Power After Ruck Marching
A study testing Loaded Walking High, Loaded Walking Mid and Walking in people with Exercise and Fatigue, run by State University of New York at Buffalo at 1 site in United States.
Trial summary
The purpose of this study is to determine change in injury risk and performance variables in males and females after walking unloaded and carrying a load with two different distributions (high-pack placement and mid-pack placement) to identify differences in injury risk Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Loaded Walking HighOther
Walking three miles on a treadmill at a self-selected speed while wearing a backpack with weight carried high on the back
Loaded Walking MidOther
Walking three miles on a treadmill at a self-selected speed while wearing a backpack with weight carried on the mid-back
WalkingOther
Walking three miles on a treadmill at a self-selected speed
| Study group | Role | What they receive |
|---|---|---|
| Unloaded Walking | Active comparator | Walking on a treadmill without wearing a pack Receives: Other: Walking |
| Loaded Walking High | Experimental | Walking on a treadmill while wearing a 30% body mass load with the weight placed at the high-back Receives: Other: Loaded Walking High |
| Loaded Walking Mid | Experimental | Walking on a treadmill while wearing a 30% body mass load with the weight placed at the mid-back Receives: Other: Loaded Walking Mid |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Oxygen Consumption
Oxygen consumption will be measured using indirect calorimetry
Measured: Upon completion of 3 miles of walking, an average of 45 minutes
Increased muscular jerk
Jerk will be measured using accelerometers placed at the torso and ankle
Measured: Upon completion of 3 miles of walking, an average of 45 minutes

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Oxygen Consumption (time frame: Upon completion of 3 miles of walking, an average of 45 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05309603, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
