The Claim
Body weight support at 30% reduces both the preferred and energetically optimal walk-run transition speeds in healthy young males, indicating that reduced muscle activation and metabolic demand under partial unloading alter gait transition thresholds.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When healthy young men walk with 30% of their body weight supported, the speed at which they naturally switch from walking to running becomes slower, because less muscle effort and energy use change when they transition between gaits.
See the scientific wording
Body weight support at 30% reduces both the preferred and energetically optimal walk-run transition speeds in healthy young males, suggesting that reduced muscle activation and metabolic demand under partial unloading alter gait transition thresholds.
When less body weight is carried, the leg muscles don't need to push as hard during walking, so the body avoids using fast-tiring muscle fibers until walking is much faster. This lets the person keep walking longer before switching to running, because the muscles stay fresh longer.
What the research says
1 studyWhen people are partially lifted by a harness (30% of their weight), they wait until they’re walking faster before switching to running, because their legs don’t have to work as hard. Less effort means they can keep walking longer before switching.
