APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The quadriceps are used strongly in stepping activities, for example stair climbing and squats. The rectus femoris will perform its function particularly in the swing phase of walking when the lower limb is being carried forward and the knee is being extended.

Detailed explanation-2: -Stair climbing activates your core muscles in your legs, such as your hamstrings, quads, calves and gluts. As a result, your legs will become stronger and enhances your movement.

Detailed explanation-3: -During stair climbing, the rectus femoris and tibialis anterior showed a higher muscle activity than the medial part of the gastrocnemius, which is the posterior muscle, and the biceps femoris showed the highest activity in the one-legged stance phase during stair walking.

Detailed explanation-4: -If you have tight hamstring muscles (muscles at the back of the thigh) it is difficult to fully straighten your knee as you bring the lower leg up onto the step. Going down stairs you rely on the strength of the quadriceps of the “remaining” leg to take the full weight as you lower the other leg to the next step.

Detailed explanation-5: -Stair climbing increases leg power and may be an important priority in reducing the risk of injury from falls in the elderly. Stair climbing can help you achieve and maintain a healthy body weight. Stair climbing can help you build and maintain healthy bones, muscles and joints.
