The Claim
During inclined treadmill walking at a 10% gradient, holding handrails while leaning backward results in a metabolic cost of 6.02 ± 2.19 kcal/min, which is not statistically different from the metabolic cost of walking at a 5% incline without handrail support (6.32 ± 1.14 kcal/min), and this posture is associated with lower energy expenditure compared to upright handrail use or steeper inclines without support.
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.
Walking on a 10% incline while holding handrails and leaning back uses the same amount of energy as walking on a 5% incline without holding handrails, and uses less energy than walking upright on steeper slopes without support.
See the scientific wording
During inclined treadmill walking at a 10% gradient, holding handrails while leaning backward is associated with a metabolic cost of 6.02 ± 2.19 kcal/min, which is not significantly different from walking at a 5% incline without handrail support (6.32 ± 1.14 kcal/min), suggesting that this posture may reduce energy expenditure compared to upright handrail use or steeper inclines without support.
When a person leans back and holds handrails while walking uphill, their body weight shifts onto the arms and upper body, which takes pressure off the legs. This means the leg muscles don't have to work as hard to push the body forward and up the slope, so they use less energy.
What the research says
1 studyWhen walking uphill on a treadmill while holding the rails and leaning back, your body uses about the same amount of energy as walking up a gentler hill without holding on — so leaning back helps you save energy without slowing down.
