The aims of the study were to examine: how many and which steps are needed to initiate and complete accelerations and turnings at different angles at different approach speeds; and how an intended ...turning angle and approach speed inf luence the magnitude of the actual turning angle in each step. Eight soccer players participated in the study. They performed acceleration and turnings: 1) from a standstill; 2) while already jogging; and 3) while already running on an outdoor soccer field. The speeds and angles were calculated from the data obtained from the high-end Global Navigation Satellite System. The high correlation between the intended turning angle and actual turning angle indicated the major turning steps during a turn. The intended turning angle revealed a large effect on the magnitude of the turning angle during the side-step (r = 0.995, p 0.01) and the following step (r = 0.950, p 0.01) for acceleration and turning from a standstill, and during the first two steps following the side-step for starts made while already jogging (r= 0.919, p 0.01; r = 0.952, p 0.01) and running (r = 0.897, p 0.01; r = 0.881, p 0.01). Further, a major part of the turning began earlier at a lower approach speed, which allowed the turning to be more quickly completed. In conclusion, the effect of acceleration with turning on the turning angle could already be seen two steps before and up to two steps after the major turning steps during a turn.
Progressivity of Basic Elements of the Slovenian National Alpine Ski School Ski school programmes in different countries are adapted to the local conditions and skiing trends. The aim of the study ...was to establish the progressivity of the three basic elements of the Slovenian ski school in terms of the duration of individual turns and their phases. Eight participants were recorded as they performed three basic elements of the Slovenian national ski school: wedge curves – E1, turns with a wedge push-off – E2 and basic swinging – E3. According to the ski school, the elements were divided into phases. The results of the computer-aided video analysis showed that in the beginning types of skiing in the same conditions on the same length of terrain, the average durations of turns and the times of comparable initiation and steering phases of the elements shortened on the methodical upward scale (from E1 to E3). The number of turns executed on the same length of terrain from E1 to E3 increased. A larger step in motor task complexity was indicated when a pole plant was included in skiing elements. Further, relatively large differences were observed in time durations among subjects executing the same elements. In conclusion, it can be assessed that the basic elements of the ski school are placed gradually in terms of progressivity in time durations. Progresivita základních elementů slovinské národní školy alpského lyžování Programy lyžařských škol v různých zemích jsou přizpůsobeny místním podmínkám a lyžařským trendům. Cílem této studie bylo stanovit progresivitu tří základních prvků slovinské lyžařské školy, pokud jde o dobu trvání jednotlivých zatočení a jejich fází. U osmi účastníků bylo zaznamenáno, jak provádějí tři základní prvky ze slovinské národní lyžařské školy: E1 – oblouk z pluhu; E2 – oblouk z přívratu vyšší lyží E3 – paralelní oblouk. Podle lyžařské školy byly prvky rozděleny do fází. Výsledky počítačové video- analýzy ukázaly, že na začátku lyžování za stejných podmínek a stejné délky terénu, je průměrná doba zatáčení a časů srovnatelného zahájení a řízení fází, jsou tyto prvky dle metodické vzestupné škály zkráceny (od E1 po E3). Počet zatočení provedených na stejné délce terénu se zvýšil; od E1 po E3. Delší pokrok byl v motorické komplexnosti úlohy, indikován při jejich začleněného do lyžařských prvků. Poměrně velké rozdíly mezi subjekty, které prováděli stejné prvky, byly zaznamenány v době jejich trvání. Na závěr lze usuzovat, že základní prvky lyžařské školy jsou postupně z hlediska progresivity podle času jejich trvání, implementovány.

The systems range from being less than fully mobile to kinematically redundant to overconstrained. In addition to recognized areas, this book also presents recent advances in emerging areas such as the design and control of humanoids and humanoid subsystems, and the analysis, modeling and simulation of human body motions, as well as the mobility analysis of protein molecules and the development of machines which incorporate man.
Nespecifična križobolja (NK) predstavlja značajni zdravstveni i socijalno-ekonomski problem zbog svoje velike učestalosti, dugotrajnosti smetnji, rekurentnosti te funkcionalne i radne ograničenosti ...oboljelih. Čest izostanak određivanja uzroka križobolje i slaba korelacija kliničke slike i dijagnostike pomoću slikovnih prikaza, prvenstveno magnetske rezonancije i rendgena ukazuju na potrebu funkcionalnih mjerenja u pacijenata s NK-om. Funkcionalna mjerenja omogućavaju kvantitativno mjerenje funkcionalnih promjena koje mogu biti uzrokom i posljedicom NK-a te razlogom rekurentnosti i radne ograničenosti. Na temelju podataka funkcionalne procjene mogu se programirati i planirati postupci prevencije NK-a te individualizirati terapijski i rehabilitacijski postupci. Isto tako, funkcionalna mjerenja tijekom liječenja i rehabilitacije omogućavaju praćenje učinkovitosti pojedinih postupaka, a po završetku rehabilitacije i procjenu radne sposobnosti. Premda je značaj funkcionalnih mjerenja za uspješnost rehabilitacije pacijenata s NK-om nedvojben, ne postoji konsenzus o standardizaciji protokola funkcionalnih mjerenja. Definiranje valjanih protokola predstavlja nužnost i važna je pretpostavka uspješnog izlječenja, prevencije rekurentnosti i razvoja kroniciteta nespecifične križobolje.
