The typological peculiarities of the higher nervous activity were studied in 98 high class sportsmen and were compared later with myocardium hypertrophy (MH) as well as blood serotonine and histamine content. The sanguine-type sportsmen with an average level of reactive and personal alarmness achieved maximal sport progress. Blood serotonine content increased progressively according to the sports skill growth and MH development. The author concludes that sportsmen with a high level of the reactive and personal alarmness together with a high blood histamine content have to be subjected to more frequent medical examinations as well as rehabilitation courses.
