Description
Climbing stairs two at a time feels harder on the thigh muscles, but what does it do to the knee joint itself? Sun and co-authors compare single-step and double-step stair ascent in young men using motion capture and computer models of the body.
The double-step style gave longer strides and deeper bending at the hip and knee. Muscle force estimates, checked against electrical signals from the muscles, showed the quadriceps working much harder early in each step under the double-step mode. Yet the force across the knee joint itself did not rise. The authors suggest double-stepping can train the leg while sparing the joint, while single-stepping stays the safer pick for people with knee problems.
