The day after the Boy Scout troops first hiking trip all of the little boys complain of sore legs. Which muscle groups are most likely to become sore, and why?
What will be an ideal response?
Hiking requires a person to walk on rough terrain with repeated flexion of the hip and extension of the knees. Also, the ankle needs to be kept stabilized on this rough terrain. It is likely that all of the hip flexor muscles and knee extensors are sore, and also that the muscles acting at the ankle are sore.
