3 health questions about my karate class

I am considering renewing my CPR certification. I would feel better having it.

In Australia, just about anyone can open a school, but for those that are certified instructors, basic first aid is mandatory. For us, both of our instructors are occupational first aiders, which is the highest level available for the public.

First aid training should be a requirement for any sports coach, but not conventional first aid because most first aid courses do not cover many issues that will come up as a matter of sport. A sport specific course would be more appropriate. Any instructor/coach that has no training at all is dangerous.

As for the overweight instructors, I agree that they should at minimum be able to perform the requirements of the lower grades.

As for the knuckle push-ups, for juniors, these are a no-no. Their bones are still forming and it will have negative effects. For adults though, no problem. It's not so much that these will increase the density of the bones or anything, it won't. It's more of a mind training excersize than anything and also helps to strengthen the wrist.

As for the knuckle push-ups, for juniors, these are a no-no.

This is true. A person's bones and cartilage is not fully developed until they are about 15-17, depending on the person. If younger children do knuckle push-ups, they can injure or halt the development of these bones, which is obviously not good.

As Jiffy said, for kids it's a no-no. For adults, it's physically fine.
