    Validity and Reliability of Devices Measuring Countermovement Vertical Jump Performance

    The counter-movement jump (CMJ) test is a standard measure of lower body power and can be related to other aspects of athletic performance. With many tools commercially available, it can be difficult for professionals to distinguish which device provides the most accurate results for the best cost. While these devices have been previously validated individually, no past studies have concurrently examined these specific tools. The purpose of this study was to determine the accuracy of four different CMJ measuring devices when compared to the gold standard of a force plate. Thirty-one physically active university students were recruited for this study. Upon completion of a short dynamic warm-up and instruction on proper jumping technique, each participant performed four maximal CMJs on the force plate. They then performed an additional four maximal CMJs in an area where four other instruments were used to measure CMJ simultaneously: accelerometer-based sensor, a contact mat, a photoelectrical cell system, and a mobile device video app. Analysis of the data was conducted, and results showed that while slightly overestimating measurements, the commercial devices that seem to agree the closest to the gold standard force plate were the contact mat and accelerometer-based sensor

    Bakalárska práca sa zaoberá problematikou Cisco akadémie a programom Packet tracer od firmy Cisco. Teoretická čast zameriava pozornosť na priblíženie učebne Cisco Akadémie. Nasleduje kapitola, ktorá špecifikuje operačný systém Cisco zariadení a kapitola popisujúca smerovací protokolo Open Short Path First (OSPF), ktorý je použitý v praktickej časti práce. Bližšie objasnuje zkladné vlastnosti a fungovanie protokolu v autonómnych systémoch počítačových sietí. Partická časť pozostáva z dvoch projektov vytovrených v programe Packet tracer. Prvý simuluje počítačovú učebnu Cisco akadémie so všetkými zariadeniami. Druhý projekt prestavuje úlohu pre študentov zameranú na smerovací protokol OSPF. V závere práce sú realizované postupy zdokumentované. Súčasťou sú i webové prezentácie popisujúce oba projekty.This bachelor work is concerned with a Cisco academy problem and a Packet tracer from the Cisco company. The theoretical part is orienting it's attention on approach of the Cisco Academy schoolrooms. Follows the chapter, which specifies the operating system of the Cisco equipments and chapter describing the routing protocol Open Short Path First (OSPF), which is used in a practical part of this work. It is making clear the basic characters more closely and protocol functioning in autonomous systems of computer networks. The practical part consists of two projects which are created in Packet tracer. The first one is simulating the computer schoolroom of the Cisco academy with all the equipments. The second project is introducing the homework for students which is oriented on the routing protocol OSPF. There are documented the realized progresses in fine. The part of it are web presentations which are describing both projects.
