What is the primary function of the knee extensors during stair ascent?

To generate most of the energy to move the body forward (correct)

To facilitate the swing phase by flexing the knee

To generate eccentric force for energy absorption

To halt forward motion during foot placement

Which phase of the sit to stand movement begins just before the buttocks are lifted from the seat?

Weight shift or flexion momentum (correct)

Lift or extension

Transfer of momentum

Stabilization phase

During the controlled descent phase of stair walking, which muscle groups are primarily engaged?

Hamstrings and soleus muscles

Eccentric contractions of the gastrocnemius and quadriceps (correct)
