Introduction: The sportsmen have been used different medicines and dietary supplements during the trainings and competitions. Theirs
quantity and quality are disputable by point of view of health protection many times. According to our opinion it is necessary systematic
health education and scientific nutrition advices to fend off pressure of consuming supplements induced by the commercial advertisements
and by psychological reasons. Sport background of these acting we should like help on with special data bases. In former researches
we fixed information during long time (7 years) one kind of sport (athletic). In the present case, our aim gain data about medicine
and supplement consumption habit and specification of Hungarian elite athletes of different discipline of sport during one Olympic
year.
Methods: The analyzed information based on the admissions of Doping Control Collection Form of different Hungarian elite athletes in
Hungary in time from January 01 2008 to December 31 2008. The Forms are recording the names of medicines and nutrition supplements
consumed by the competitors ten days prior the control. We have created a database out of these data.
Results: The members of examination were representatives of 32 Olympic-, 12 Paralympics- and 5 non Olympic -disciplines.
The total sum of Doping controls was 1518 (n= 851m, n=667w) out during in the given period of time.
The competitors of Olympic disciplines have been participated 1396 in case n=766m (503 urine samples, 263 blood samples), n=630w
(422 urine s, 208 blood s).
Non Olympic sportsmen were checking 61 in case, n=43m (41 urine s, 2 blood s), n=18w (17 urine s, 1 blood s).
Paralympics had controls 61 in case, n=42m, n=19w all in urine.
In the period of survey only in case 70 (4.6%) hasn’t use any medicines and dietary supplements.
Use of the prohibited medications with license were detected 97 (6.38%) in case. (n=50m, n=47w)
Numbers of articles named by Hungarian elite athletes were investigated grouped to medicines and nutrition supplements by the athlete
gender and disciplines of sports.
Conclusions: It has been discovered from Doping Collecting Forms too many sports men use different non steroid medicines and pain
relieves with together.
After detailed analyzing of consumption of vitamins, the results showed too many competitors used by more types of vitamin complex.
In our opinion there is a high rate of consumption if somebody used five or more dietary supplements in the checking period. We was
detected 66 in case (n=49m and n=17w) when the number of taken supplements are over then 10.
Conclusions of our examination that significant numbers of sportsmen do not used the supplements according to needs.
For optimization of nutrition advices should be a theoretically accept for sports, like the standards RDA, ODI, PDI.

PHYSICAL ACTIVITY AND EXERCISE-INDUCED LYMPHOCYTE APOPTOSIS

Introduction: A decrease in lymphocyte counts and changes in its composition has been described after prolonged and sustained vigorous
exercise. To evaluate the contribution of apoptosis to lymphopenia during early recovery from acute physical exercise in humans, a
systematic review has been carried out.
Methods: From January 1998 to August 2008, 11 studies investigating the incidence of apoptosis in human blood lymphocytes during
early recovery from an acute exercise bout have been published. They comprise of 17 effects from a total sample of 90 volunteers. Exercise
mode differed greatly among studies and included; short duration (70%VO2max) intensity exercise; prolonged (>120’) exercise; eccentric exercise and progressive maximal exercise. In all cases,
venous blood samples were collected before and early after the exercise bout. In some studies, a third sample time-point was allocated
at some time between 1 hour to 24h of recovery.
Lymphocyte apoptosis was analyzed by cytometric procedures or by optic microscopy determination of apoptotic morphological
changes.
Results and Discussion: Results show that an intensity threshold can exist as exertion below 60%VO2max did not induce significant
changes in apoptosis parameters such as annexin-V or CD95 expression, or caspasses activities in lymphocytes. On the other hand,
increases in percentages of lymphocytes expressing annexin-V or CD95, or in caspasse 8 and 9 activity (Mooren, 2002; Tuan, 2008;
Wang, 2005) have been reported immediately after intense exercise. Sixty minutes after exertion values had returned to resting levels,
except for the percentage of NK cells expressing CD95 that were still elevated (Simpson, 2007), and for caspasse 3 activity that increased
at 24 hours of recovery (Wang, 2005).
A duration threshold can also exist seeing that percentages of annexin-V or CD95 lymphocytes were superior after long duration running;
and persisted elevated for a longer time; than after short duration running at a similar speed (Mooren, 2004; Steensberg, 2002).
Navalta (2005) notes an increase in percentage of lymphocytes with morphological signs of apoptosis immediately after a progressive
and maximal exercise test that returned to resting levels in the first hour of recovery.
