I am ready and open to get the usual gibberish comment and blame,but anyone would also care to answer at least to a very simple question of mine: with all the morpho-biomechanics of the world how does a 8-10 yo’s biceps brachii differ in nature,and function from a 14-16 yo’s one? Don’t they both primarily flex elbows,for Americans,as well as Bulgarians,and for the all-mighty Russians too,however structured or less structured the personality of the individual,and even for the smartest and most sophisticated graphologist and/or marriage consultant out there ?
Honestly,to me this all goes a long way explaining the MASS confusion reigning in today’s world of sports training AT ALL LEVELS.

Svincenz,you have fisrt hand,day to day experience of PRO euro soccer,as I do,so you’ll know how the injury rate in major European competitions has climbed to the roof this year (36% increase). Do you know also what was the conclusion the experts got to as far as the cause of all this based on all these studies,and sciences we all base our OPINIONS upon? Winter temperatures and humidity changes. Global warming.
Aren’t we HUMANS (athletes or not!) designed to function in different environments and adapt ? Isn’t training supposed to make ALL OF US humans more and more proficient at this?

Gibberish,or not,I’ll sit here anyway waiting for what they will come up with next Spring and Summer,do my job,and have a honest laugh in the meantime.
