Improvements of athletic capacity in high-performance sport are mainly achieved through an increase of the quality of training. In physical preparation, the quality of training can be improved by developing highly specific means of training. The aim of this paper is to present three examples of how highly specific means of fitness training of world class athletes can be developed. The first exa...

Introduction: Oscillation based test (OBT) method [1] has been applied to testing different types of analogue circuits [2-5]. In this approach, the circuit is transformed into an oscillator during the test mode and the frequency of oscillation is measured and compared to the reference value obtained on a known-good circuit operating in the same conditions. Circuit modification for the purpose o...

Throwers, jumpers, and combined events athletes require speed, strength, power, and a wide variety of technical skills to be successful in their events. Only a handful of studies have assessed the nutritional needs of such athletes. Because of this, recommendations for nutritional requirements to support and enhance training and competition performances for these athletes are made using researc...
