The Claim
In healthy young adults aged 22–27, walking for 60 minutes at a normalized speed of Fr=0.25 produces a maximal compressive strain of 5.0% in tibial cartilage, with strain increasing monotonically during the first 40 minutes and plateauing thereafter, indicating in vivo creep behavior that provides a physiological benchmark for cartilage mechanical response to daily activity.
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 adults walk for 60 minutes at a normalized speed of Fr=0.25, their tibial cartilage experiences a maximum compressive strain of 5.0%, with strain rising steadily for the first 40 minutes and then stabilizing, demonstrating a measurable mechanical response to walking.

When you walk, the weight on your knee pushes down on the cartilage, squeezing out fluid inside it. This fluid moves slowly through the cartilage’s sponge-like structure, causing the cartilage to get thinner over time. After about 40 minutes, the fluid stops moving out because it has spread out evenly, so the cartilage stops getting thinner even though you keep walking.
What the research says
1 studyStudy: A New Stress Test for Knee Joint Cartilage
When healthy young adults walk for an hour at a normal pace, their knee cartilage gets about 5% squished — and it keeps getting squished for the first 40 minutes, then stops getting squished more. This study directly measured that exact behavior for the first time in real people.
