Is walking downhill a concentric or eccentric contraction of your quadriceps muscle?
Every step, whether going uphill, downhill, or on flat land, involves both an eccentric and concentric contraction.The eccentric contraction occurs when the quadriceps muscles lengthen as they load. In order for your quadriceps to lengthen, the knee must bend. Thus, the eccentric contraction in the walking motion occurs just after you step. This is perhaps more obvious with running than walking. After the foot touches the ground, the quadriceps is loaded eccentrically by the weight of the body as the knee bends.The concentric contraction of the quadriceps occurs then when the muscle shortens, as you push off from your foot. Again, this is probably more obvious with a running motion than walking motion. After the weight of your body has shifted onto the foot that is currently in contact with the ground (with your knee bent), your quadriceps contracts concentrically as the knee unbends and you lift your own body weight.So walking, even downhill, still involves both eccentric and concentric contractions. Walking (and running) downhill can lead to fatigue in your quadriceps due to the greater eccentric loading that occurs when going downhill. The range of muscle motion can be greater and your body is coming from "higher" up (its previous elevation on the hill), which can increase the load as well. As compared with concentric contractions, eccentric contractions can cause more damage to the muscle.

Could anyone tell me what knee injury I have?
I'm 20 years old and pretty athletic, but i've never really had a big injury before. I was walking downhill when i slipped on a loose rock, but caught myself on my left leg and it hurt my knee. It's not an intense pain because I can walk without even feeling it, but when I bend it and then put weight on it (crouching then standing) is when it hurts. Again, not an immense pain but sort of an annoying pain, almost like I pulled a muscle in my knee.
What are the symptoms of patellofemoral pain syndrome?
The main one is pain behind your kneecap. That really is the giveaway that something is wrong. You might have some pain from sitting, walking, or running for a long time. The pain is sometimes worse walking downhill or down a flight of stairs. You might feel or hear snapping, popping, or grinding in the knee. Your knee may swell at times.
My knee hurts to walk on and stand on but there is no swelling?

Can walking uphill but slowly burn as many calories as walking quikly down a hill?
Walking on level ground is moving balance weight. This requires far less energy than walking uphill or downhill. Walking uphill burns almost twice as many calories as walking in flat land. Walking downhill burns more than walking on flat land simple because you are transferring weight down and in doing so you move your total weight down on one leg at a time. Walking downhill uses about half the extra energy walking uphill compared to walking on flat land. If your knees will permit you to walk up and downhill, you will not only burn more calories, but the muscles in your legs will strength and you will have far less body fat on your legs. I have a pretty steep hill I walk daily. It is the main factor for me being able to control my weight. Invest thirty days and experiment with this. You will be pleasantly surprised and will be able to control your weight in the future. I wish there was a way for people desiring to lose weight to find out about it. There is more of a chance for a knee injury. Be careful.
