An old article I found in my text books:
Biomechanical Study of Full-Contact Karate Contrasted with Boxing"
Schwartz, ML; Hudson AR; Fernie GR; Hayashi K; Coleclough AA
Journal of Neurosurgery
Volume 64, Issue 2, Pages 248-252 (1986)
It is known that boxers suffer a characteristic cumulative brain injury from repeated blows to the head that correlates well with the number of bouts fought. Much less is known about full-contact karate (kickboxing), which is relatively new. In full-contact karate, punches and kicks are actually landed, rather than being focussed to culminate just short of an opponent, as practised in traditional karate. Although a combatant can win on points, the surest means of victory is a knockout. Consequently, fighters strive to land blows to the head. To investigate the relative force of kicks and punches, a dummy head was mounted 175 cm above the floor (to simulate a 50th-percentile man standing erect) and 125 cm above the floor (to simulate the man in a crouched position) on a universal joint permitting motion about three axes. The mechanism was contrived to provide constant rotational stiffness, and springs provided constant restorative moments about the three axes. The texture of soft tissue was simulated by a mask of visco-elastic foamed materials. Fourteen karate experts punched and kicked the dummy. Accelerometer measurements in the 90- to 120-G range indicated that safety-chops (hand protectors) and safety-kicks (foot padding) did not reduce acceleration of the dummy. Ten-ounce boxing gloves mitigated peak acceleration to some extent. Kicks and punches produced accelerations in the same range. Violent acceleration of the head by any means produces injury. The authors conclude that, if full-contact karate is widely practised, cases of kickboxer's encephalopathy will soon be reported.

"Accelerometer measurements in the 90- to 120-G range indicated that safety-chops (hand protectors) and safety-kicks (foot padding) did not reduce acceleration of the dummy."
The main advantage of these pieces of equipment is the protection of the hands and feet. In bare-knuckle boxing days, the pain to the fists somewhat limited the amount of punches thrown.
Padded gloves such as those in boxing might help reduce cuts, but that's a "double edged sword" type of situation. Fight goes on longer, which means more opportunities to get popped in the head.
BTW, is the baby in the photo your child? He/she looks very cute!

I though the g rating on the head impacts were kind of cool to see again.
1% Shark is better than you.

What are comparable G ratings for boxing?
Posted On:12/15/2003 2:44pm
Pretty much the same

You wouldn't happen to know who the karate experts were by any chance, would you Ronin? Was it mentioned?

I thought the reason NHB or whatever you want to call it was much safer because the ref stops the fight as soon as a guy goes limp from strikes, rather than issuing an 8-count or 10-count. Boxing is designed to go on as long as possible.
