Answer only to the most mainstream styles of Muay Thai and extreme karate.
Basically, it is inevitable, the farther the distance, the more inclined the action is to the long power chain, and the closer the distance, the more the action is biased towards the angle change. The difference in competition style has created a huge difference in technique between the two sides: Muay Thai is far away from the leg output, because it is close to hug; Karate is infinitely close because the hand is not on the head, so the leg is important at close range.
Later, the masters on both sides used not only the method, but also the thinking was different. We can understand it this way, Muay Thai chooses the movement, and karate chooses the landing point.
If you use one movement to represent Muay Thai, it is basically a mid-leg kick, which undoubtedly accounts for the largest proportion of Muay Thai fighters' training, and the high use rate is terrifying. A strong Muay Thai fighter can finish a fight with a mid-kick alone, you push forward and I sweep you back, if you go backward I press with a mid-kick, if you run in both directions I sweep you back... In order to achieve this effect, you have to pursue two points, one is the ultimate power, and the other is the ability to hold down people, so that people will not take advantage of the empty leg to get close - this is the advantage of Muay Thai legs.
Karate, on the other hand, is much faster paced than Muay Thai, which allows for finer control over angles and routes. Karate's leg moves are more complex than Muay Thai fighters, or even other schools of thought besides taekwondo. will focus more on damage accumulation. If I want to represent a karate player with a technique, then I choose the lower kick, but the lower kick is not one movement, but an infinite number of movements. Speaking of which, the lower kick is very much a reflection of the Japanese national character, because it is the technique that the Japanese find to be very effective in the Thais, and the Thais pay the least attention to it, and the Japanese successfully overtake in the corner. Karate players will be as detailed as possible, the Thai low kick is a low kick, karate will take into account the kick of the upper thigh, lower thigh, inner thigh, outside, front, knee socket, inner knee, upper and lower calf, calf inner test, the landing point is precisely considered to maximize the effect. Karate likes to continue to accumulate damage at a landing point, and when I choose this point, I hit this point in various ways, which is the choice of the landing point. So if there is an advantage of karate leg method, it is "thin".
There are advantages and disadvantages, Muay Thai is not fine enough, and karate is not so universal.
