Why is Steve Nelson not dead?
Duuuuuh Cuz it is the ring.
And this is why I'm dropping my USJA membership and going through USJF. Competing for points sucks at my age and with my schedule, but so be it.
Second, I said "with sufficient power". In both cases the attacker was using arm strength to deliver strikes, and not dropping body weight.
Third, MMA competition have outlawed strikes to the back of the head, the neck, and the spine because these blows can be fatal. Kidney strikes have more leeway because they aren't instantly fatal. The UFC disallows heel kicks to the kidneys.
Forth, did you notice that in both cases, these strikes ended the fight? What if a ref isn't there to stop a fight and the blows keep coming? Then they would die.
A layer of plywood with (guessing) at least a hundred automotive valve springs attached to each 4x8 sheet. Two layers of plywood on top, screwed together.
Two different layers of mats with different thickness and density. A canvass cover stretched over all and tightened through eye bolts.
A true thing of beauty and best shock absorption of any tatami I've experienced. Footing is fantastic, especially those turning and pivot movements that tend to be hard on the knees where some mats can tend to grab the foot.
Only downside is if you burn a foot, knee or whatever on the canvas. Hydrogen peroxide and cotton balls to clean any blood.
Windsong does have possibly the premiere mat in the state.
