first off, this is a great discussion.
When I distinguish between organism and human I am referring to the difference between the biological systems and morpho-biomechanical structure that are, fundamentally (in terms of the common principles associated with how the systems and structures function) , shared between all athletes and the actual peculiarities which differentiates each individual.
Perhaps I should have used the terms organism and athlete X
So I plan training by considering the biodynamic/bioenergetic structure of sport- then weigh these variables against what I know about the organism and how it operates- THEN individualize the program for the needs of the actual individual athletes who, hopefully, have been properly selected.
Preface, knowing implies certainty while belief implies hope.
That said, I know that optimal training preparation requires that when we sit down to program and organize the training for our athletes we must begin by conceptualizing the biodynamic and bioenergetic structure of the sport/discipline in which they compete.
From this, we acknowledge the true taxonomy of the sport requirements and from this we are able to ascertain just how well selected the athletes are for these requirements.
As you pointed out Svincenz, I am speaking from a higher performance level as I am a staunch advocate of competitive sport being comprised only of athletes who are predisposed to accel at them.
One of the many principles I adopted from the Soviets is that competition shouldn’t even take place until the participants are able to truly compete at a level high enough to challenge other individuals and teams of a national/international, collegiate, professional, Olympic, level. Granted, this is my opinion only; and my opinion renders me in an extreme minority in my country.
Having said that, it is easy to surmise that my feelings on physical preparation for youths MUST be void of concern for various sport demands until it is clear from a morpho-biomechanical standpoint that the young athlete is predisposed for high results in certain sports only. Meaning, the field must be narrowed before specialized training occurs.
As we know, due to the biodynamic and bioenergetic requirements of various sports, the age of specialization varies.
In the US, I see the gross mistakes that are made in the technical-tactical sport training.
Thus, it is necessary that I assume some of this vital responsibility as a physical preparation coach and has thus required that I broaden my skill set beyond the mundane tasks of the bigger, stronger, faster status quo in my industry.
To do this, my efforts must extend beyond general preparation only, and include specialized training.
It then follows that this is only possible if I am qualified to dissect the biodynamic and bioenergetic structure of the sport- something which, surprisingly, many western technical-tactical and S&C coaches are unable to accomplish with high accuracy; rendering a certain percentage of both sport practice and physical preparation unwisely used.
