Hollman and T. Hettinger (5) have determined the common to all, innate potential of the human organism (inclusive of the nervous system and muscles). The have divided them into four parts: · reserves employed in reactive movements (15%); · "physiological" reserves employed under conditions of elevated motor activity (20%); · "special" reserves mobilized only under conditions of muscle performance of great intensity or long duration (35%); · "innately defended" reserves mobilized only in extreme, life- threatening situations (30%). The third and fourth segments of the reserve potential are distinguished by their mobilization barrier, inhibited by the central nervous system. Overcoming this barrier under normal living conditions is precluded by a protective inhibition, which forces the body to reduce the intensity of the work, or cease it. To overcome of this barrier with doping can cause irreparable harm to health and can even be lethal. Based on the W. Hollman and T. Hettinger scheme, it is possible that systematic sport training draws upon the "physiological" reserves of the body; and that high class sportsman utilize "special" reserves (20,29). ============= Jamie Carruthers Wakefield, UK
