Muscles have two types of fibers:  fast-twitch and slow-twitch.  Fast-twitch are used for high-intensity, vigorous, fast motions such as jumping and sprinting; slow-twitch for just the opposite, like walking and most other low-intensity activities.  Generally, heavy-weight lifting uses fast-twitch fibers more and hiking uses slow-twitch more.  That said, developing strong muscles and tendons, even if your exercises emphasize fast-twitch fibers, will be good for joint stability and will decrease the risk of injury on and off the trail.
