Summary: Muscle damage, recurrent and serious infections or exercise-induced fatigue especially to the end of the playing period in team sport or to the end of preparation for competition in endurance or single sport are the most common symptoms in elite sport demolishing optimal training results. Are micronutrient deficiencies responsible for these symptoms in elite sport. Methods: In 111 elite athletes [male: 50 – female: 61 / soccer: 21 – field hockey: 62 – Olympics: 19 – tennis: 5 – motorsports (DTM-Formula1): 4] blood vitamin D, coenzymeQ10, vitamin B1-B2-B6-B12 and folic acid as well as selenium, ferrum and magnesium intraerythrocytary were determined. In all elite athletes the symptoms muscle damage, infections, sleeping disorder and fatigue were correlated. A Spearman-ranking coefficient of correlation, a chi-quadrat-test by Pearson and an independent t-test were used. p<0,05 was supposed to be significant, p<0,01 highly significant. Results: In 51,3% of all elite athletes (N=57/111) a vitaminD-deficiency (< 30 ng/ml), in 57% (N=61/107) a seleniumdeficiency (< 121 µg/l), in 70% (N=77/110) a coenzymeQ10-deficiency (< 750 µg/l) and in 27,1% (N=19/70) a magnesium deficiency intraerythrocytary were established. In cases of young player (< 18) vitaminD and of young national player (U16- U21) ferrum intraerythrocytary compared to national A player were poorly supplied [vitaminD: 25,71 ± 9,58 ng/ml vs 35,87 ± 12,35 ng/ml (p=0,007) – ferrum: 407,13 ± 43,09 mg/l vs 460,29 ± 36,69 mg/l (p=0,018)]. Muscle damages (in 73% of all cases) significantly occurred in vitamin D deficiency [29,13 ± 9,38 ng/dl vs 36,27 ± 12,09 ng/dl, p=0,005] and in coenzymeQ10 deficiency [623,31 ± 226,31 µg/l vs 732,93 ± 408,19 µg/l, p=0,039] more frequently. Comparing the settings of vitaminD <40 ng/ml vs > 40ng/ml [27,50 ± 7,85 ng/ml vs 46,31 ± 6,71 ng/ml, OR=4,53, p=0,007] muscle damage were observed 4,53 times more frequent in the lower group, whereas the settings of vitaminB1-(thiamin) < 50 µg/l vs > 50 µg/l [36,45 ± 7,01 µg/l vs 63,24 ± 24,33 ng/ml, OR=0,38, p=0,045] showed muscle damage in 62% less frequent in the lower group. No significances were observed in infection, sleeping disorder or fatigue. Conclusion: Independantly to the type of sports, except all B-vitamines, deficiencies of essential vitamins and trace elements in elite sports were observed. VitaminD- as well as coenzymeQ10-deficiencies and vitaminB1-excess play an important and significant role developing muscle damages. Further studies preventing muscle damages, recurrent infections and fatigue by treating elite athletes with micronutrients to eradicate those deficiencies are necessary.
