PROBABLY WALKING (COMPETITIVE ONE)!

PROBABLY YOUNG, ALTHOUGH STUDIES DO NOT DEMONSTRATE SIGNIFFICANT DROP IN
LATER AGES. THAT IS PARTLY EXPLAINED BY A GRADUAL CONVERSION OF FAST INTO
SLOW-TWITCH FIBERS IN LATER AGE.

BIOMECHANICAL SCALING (SEE MCMACHON'S BOOK "MUSCLES, REFLEXES AND
LOCOMOTION) DEMONSTRATE A DECREASE OF ENERGY EXPENDITURE PER WEIGHT UNIT
WITH INCREASE OF BODY SIZE.

I DON'T KNOW, BUT IT IS OBVIOUS THAT VARIOUS INJURIES, NEUROLOGICAL
PROBLEMS ETC. SHOULD DECREASE EFFICIENCY.

THE QUESTION IS TO GENERAL. ATHLETIC ACTIVITIES OFTEN CAUSE VARIOUS
INJURIES, BUT ALSO PREVEN OTHERS.

I HAVE AN EXTENSIVE COMPETITIVE EXPERIENCE IN KARATE AND I AM POSITIVE THAT
YOUR TEACHERS DO NOT HAVE ANY CHANCE AGAINST YOUNG AND, PROBABLY HEAVIER
COMPETITORS. SORRY TO DISSAPOINT YOU, BUT THEIR ONLY ADVANTAGE IS A
PSYCHOLOGICAL ONE, PARTICULARY DURING "KUMITE" WITH THEIR OWN STUDENTS AND
WITHIN THEIR OWN CLUB.
