Hey i was at a tournament the other day and it was the first place match. I had to forfeit due to injury, because i didn't know how to stretch this muscle or what this muscle is even called. I put quadriceps in the title cause its in that area. When i went up for a jump smash, i kicked my legs out for power and it just locked. Usually my legs would bend back in to soften the landing but it didnt, and i ended up falling. My legs were stuck for 10 seconds and pain shot through the outer sides of my thighs, just above the knee. Does anyone know how to prevent this from happening? I tried many stretches but none targetted the outer thigh area. Does anyone know of stretches to target that area? A friend gave me this knee support but it was below the knee so it didn't really help.
