The aim of this study was to examine the hormonal and strength responses to different periodization models of resistance training in male athletes. Eighteen experienced resistance trained males were randomly assigned to either a block (BP; n=10; age: 23.7±2.9 yr; body mass: 78.5±11.3 kg; height: 1.77±0.05 m) or weekly undulating (WUP; n=8; age: 26.0±5.7 y; body mass: 78.9±12.4 kg; height: 1.79±...

A new mixer for a diesel engine after-treatment system is developed to meet the requirements of China VI emission regulation. As structure mixer, it surrounded by spiral blades, and center staggered with small which conducive crushing urea droplets can make fully mixed air, improve conversion efficiency nitrogen oxides (NOx) reduce ammonia leakage. The numerical analysis, bench test, vehicle ro...

The aim of this study was to find a trend of changes for selected anthropometric characteristics and motor abilities of young male and female tennis players of three different age groups. Trends were observed in the periods between 1992, 2000 and 2008. In addition, a comparison of results of tennis players and school pupils was included. The sample of subjects were selections of young tennis pl...

This study deals with performance issues for connecting points to a network in geographic accessibility studies. The problem is analysed by the development of a test bench where the spatial indexation methods kD-tree, Morton code and fixed grid are implemented. Using the test bench scenarios of networks, point datasets, spatial indexation methods, and methods for computing distances between poi...

Selbst mit den neuesten Modellierungswerkzeugen und dem Einzug von Objektorientierung und Abstraktion in die Hardware-Entwicklung ist der Aufwand für die Verifikation immer noch bestimmend für den gesamten Entwurfsprozess. Wiederverwendbarkeit und Flexibilität sind deshalb aus ökonomischer Sicht unabdingbar. Es wird eine SystemC-Verifikationsumgebung vorgestellt, die sich besonders für paketver...

The sport of strongman is relatively new; hence, specific research investigating this sport is currently very limited. The purpose of this study was to determine the relationships between anthropometric dimensions and maximal isoinertial strength to strongman performance in novice strongman athletes. Twenty-three semiprofessional rugby union players with considerable resistance training and som...

The aim of the present study was to identify different cluster groups of handball players according to their physical performance level assessed in a series of physical assessments, which could then be used to design a training program based on individual strengths and weaknesses, and to determine which of these variables best identified elite performance in a group of under-19 [U19] national l...
