Introduction. In
sports medicine malnutrition which meet especially in sports per weight
categories, effects the T cell-mediated immunity, disturbs the
complement system, the phagocyte(macrophage) activity, etc. The total
lymphocyte number may represent a marker of malnutrition, only if we
exclude an infection, a disease associated with depression of the
immune system (but the high-performance sports do not depress the
immune system?), or a haematological disease; stress and corticotherapy
(often used of athletes), may also induce immunodepression.
Materials
and methods.
The study was effectuated on volleyball players from team ,,University
of Timisoara” from the first division in the competitional
years 2004-2005 with a number 13 players. The coefficient
limphocytes/leukocytes has been calculated eich threshold value is
0,35, and which has diverse value for quantification the immune system
at athletes. The number lymphocytes per mmc (2500-3500) may represent a
useful marker for the diagnosis of the protein - calorie malnutrition
(PCM); so, a decrease below 1200-1500/mmc represents a light
malnutrition, while a decrease below 800/mmc represents a severe
malnutrition.
Results.
We present in the graphics evolution of the lymphocytes/leukocytes
coefficient in different stages of the study effectuate during a year
competition at athletes volleyball players from team ,,University of
Timisoara”. From the date analysis it can be observed: an
general basal mean values of this coefficient are below the optimal
number 0,35 and along the trainings (august 2004), the coefficient
value decreases slightly, being maintained constantly under the
threshold number. In both
official games the coefficient
decreases significantly after the game and 60 minutes after the game
the mean coefficient values are still below the normal values, perhaps
meaning a stressing action of the sportive effort upon the lymphocytes
immune system.
Conclusions.
The supervision of this coefficient could be used in the
medical-sportive control of volleyball p0layers, participants in
internal or international competitions, with a guiding marker of the
immune reactivity compared to the stress induced by the sportive effort.
