San Shou -vs- Muay Thai Leg Kicks
It depends on what the goals of your training are and who you intend to fight (ie. san shou, mauy thai, street defense, etc..).
Use whatever works best for YOU…now for you to find out that answer, you’ll need to mix it up full contact with some good fighters from various styles and understand how you may use it in a self defence situation.
Personally, I like the san shou version and think it may have some advantages, but then again i’m biased and others experiences will inevitably vary. These observations are based on my own experiences and also on my interpretation of the coaching I’ve had.
The MT leg kicks are done with the body in more towards the opponent and locked more with the kick, which is a straighter leg and generates power a bit differently than the san shou leg kicks, more like a Chinese ‘iron broom’ type technique. This puts the fighter inside in a position to follow up with a short range technique like a punch or elbow…This is just my observation on the MT kicks, i’ve never studied MT, but have seen footage of the China against Thailand SS vs MT team fights and could see this difference. Also i’ve gone many rounds with some pretty good MT fighters, several come to our gym and cross-train and spar with us on a regular basis. I can not discern any advantage to the MT kicks, they don’t hurt any more than SS kicks and are probably easier to trap/catch and throw…but then again they don’t have as much experience with people trying to catch those kicks.
Since the throws and takedowns are such a big part of san shou, and some of the techniques are longer range (like side kick which isnt used in MT, as far as i know), the san shou leg kicks are performed with the body back a bit, turning and the leg whipped out, but make no mistake, it is a penetrating kick with the entire body and not just a snap kick. It is not a ‘chambered’ kick but has a bend to it that then whips out…It is fluid and not ‘baseball bat-like’, making it adjustable. It is not a tentative kick though, there is commitment and follow-thru once its fired and if missed should be planted straight down or could be chambered into a follow-up side kick or something else that goes with the momentum. The SS kick doesnt automatically bring the body in with it into close range, but can still be used to do so, and there are a lot of other ways to get inside besides always following in the leg kick in the same way, which might be vulnerable to a counter or throw. It can be adjusted to work much like the MT leg kick, depends on what you’re using it to do.
If your legs and body are properly tempered/conditioned and trained, the kicks arent that big a deal to catch or even flat out take. Once in a while you really feel a good clean one though. The most painful kicks i have felt are by san shou guys, but i know there are some devestating muay thai fighters out there. Again, experiement with both and see which one works best for you.
