I've noticed recently if im doing a spinning kick, example tornado kick with speed i feel a sharp pain on my groin area.. I have no idea really why its happening, im thinking its because I possibly did something wrong or maybe doing something incorrect when im trying to improve speed..

If anyone experienced this your advice will be greatly appreciated.

I can think of several things that might be going on.

1. You may have pulled one of the many muscles in the pelvic and hip areas. Depending on which on it might only bother you during certain movements. So the simplier kicks might not affect it but more complex ones would. So the question is do you feel pain/dyscomfort during any of your kicks or just the spin kicks.

2. Proper pivoting is essential for all spin kicks. If your not pivoting in a correct fashion related to the rest of your body. A straining feeling might occur in various parts of the body.

3. Lack of flexibility. Being able to do splits in only one plain of direction does not guarantee that you will have the same motion in other plains. Since spin kicks travel over various plains you need to have increased flexibilty in all plains.

4. A hernia might have occured.

5. As one increases speed the chance of injury increases due to the muscles not being conditioned and techniques tends to suffer when we go outside of our normal speeds.

I agree with everything tigermedic said. Some variables that may cause pain are the height of the kick, height of the jump and stretches/warm up done before hand. If you're not already, you might consider including side splits in your stretch. Another good warm up is to stand in a natural fighting guard and swing your back leg straight up in front, starting low at first and working your way up.

One warm up I've started doing recently might help. Start with your feet shoulder width apart, standing in ready position, with your hands up like a fighting guard. Start with a deep squat, then do a step through side kick to the right (step past your right foot [behind] with your left, and kick to the right side), step back the same way (right in front of left), now you're back in the middle. Squat again, now side kick to the left in the same fashion. When you're back to the middle, squat again, but this time, so a front kick (with proper pivot) with the right leg. Re-chamber, and put your foot back, squat, and kick with the left. Next squat, right leg round kick to the front, re-chamber, back, squat, left round kick. Finally, squat, look over your right shoulder, and execute a right a right leg back kick, repeat on the other side. (For anyone else reading, for a good workout replace the squats with squat thrusts [you can also do a push up and frog jump in each set.])

If my directions are difficult to follow, I would be happy to make you a video guide.
