Peformance enhancing drugs are widely used today in different sport fields, and therefore the successful anti-doping activity should be based not only on regular doping controls, but also it should show the real alternative: how to replace the forbidden doping substances with legal and effective supplements. The paper deals with application proposition of protein concentrates, free AA (amino acids), HMB (hydroxy-methyle-butyrate), creatine and camitine. If the athlete is involved in strength and power sport (e.g. throwing events in track and field, olympic weightlifting etc.), the explosive and maximum strength is of primary importance. For strength athletes, these mentioned substances are those legal preparates, supplements, which can help effectively in performance improvement of sport results. The main reason is that using protein concentrates, AAs, HMB, creatine and camitine, the anabolic (and anticatabolic) effect will enhance the protein biosynthesis of the organism, improve the aerob and anaerob capacity of the athletes, activate and stimulate the own hormonal system. And the final result is creating higher loadability because of the faster recovery, and higher performance level on the competition. Of course, the athletes--as a minimum requirement--need an adequate nutrition (good balanced nourishment), as well, with appropriate application and supplementation of all vitamins and essential minerals. 展开更多

Seismic gap method is one of the effective earthquake prediction methods using seismicity patterns. However, this method has some limitations and uncertainty when using it singly in predicting earthquakes. This paper puts forward the prediction method using the dynamic seismicity pattern with dynamic implications. This method considers the formation and evolution of the seismic gap on the basis of plate movement and structural characteristics. Through analysis of 26 cases of earthquakes of MS≥5.0 occurring in East China and South China, this paper obtains the relationship between the main shock with seismic gap and active fault's location, as well as the relationship between the seismic gap and location and strike of active faults. Meanwhile, this paper provides a dynamic explanation of the differences in the formation and evolution patterns of the seismic gap between the two regions, thus providing the physical basis for and reducing the uncertainty of predicting earthquakes using the seismic gap method. 展开更多
