Can flip turns make your knees hurt?

Question

I just learned how to do a flip turn yesterday and i swam laps all day. When i came home my knees were mad sore. is this normal?

Answer 1

yes you we exersizing  "i swam all day" so YES your knees will hurt if you do

Answer 2

you are hyper extending your knees, kinda like tennis elbow. that is why they hurt. ask your instructor to show you in slow motion how to flip and you will see that his legs do not forcibly go straight at the turn. they straighten second(s) later to kick. the instructor will probably do the first stroke with his? arms to facilitate the straightening of his legs. hope this helps.
