Change of muscle contraction rate before and after the application of sports massage

Title: Change of muscle contraction rate before and after the application of sports massage Objectives: The aim of this work is to find out if sports massage of leg effects the muscle contraction rate of musculus vastus medialis and musculus vastus lateralis. Part of that aim is to compare differences of muscle contraction rate between men and women. Methods: The research was realized in a form of quaziexperiment and 8 probands took part in the research. Results were obtained from the TMG machine in the lab in department of physiology and biochemistry UK FTVS. First of all we measured proband's height and weight, after that we measured muscle contraction of musculus vastus medialis and musculus vastus lateralis on left leg. After the first measurement the proband had a sports massage of left leg. After the massage was the second measurement of muscle contraction of musculus vastus medialis and musculus vastus lateralis. Results: The muscle contraction rate of musculus vastus medialis of all probands before massage was 24,11 ± 1,87 ms and 24,35 ± 1,96 ms after massage, the muscle contraction rate of men before massage was 25,11 ± 1,5 ms and 25,59 ± 1,47 ms after massage, the muscle contraction rate of women before massage was 23,11 ± 1,65 and 23,1 ± 1,55 ms after massage. The muscle contraction rate...Název: Změna rychlosti kontrakce svalu před a po aplikaci sportovní masáže Cíle: Cílem práce je zjistit, zda kondiční sportovní masáž stehenní oblasti ovlivní rychlost kontrakce musculus vastus medialis a musculus vastus lateralis. Dílčím cílem pak je porovnání těchto změn mezi ženským a mužským pohlavím. Metody: Výzkum byl proveden formou kvaziexperimentu, kterého se zúčastnilo celkem 8 probandů. Výsledky byly získány z TMG přístroje v laboratoři na katedře fyziologie a biochemie UK FTVS. Proband byl nejprve změřen a zvážen, poté se změřila kontrakce musculus vastus medialis a musculus vastus medialis na levé noze. Po změření kontrakce byla provedena masáž levé nohy. Po absolvování masáže si proband lehl na lehátko a byla mu podruhé změřena kontrakce musculus vastus medialis a musculus vastus lateralis. Výsledky: Svalová kontrakce musculus vastus medialis celé zkoumané skupiny před masáží byla 24,11 ± 1,87 ms a po masáži 24,35 ± 1,96 ms, muži měli rychlost kontrakce před masáží 25,11 ± 1,5 ms a po masáži 25,59 ± 1,47 ms, ženy měly rychlost kontrakce před masáží 23,11 ± 1,65 ms a po masáži 23,1 ± 1,55 ms. Svalová kontrakce musculus vastus lateralis celé zkoumané skupiny byla před masáží 25,96 ± 4,27 ms a po masáži ± 27,23 ± 5,04 ms, muži měli rychlost kontrakce před masáží 27,60 ± 4,70 ms a po...Zdravotní TV a tělovýchovné lékařstvíFakulta tělesné výchovy a sportuFaculty of Physical Education and Spor

Efficient Transport Logistics, An Approach for Urban Freight Transport in Austria

To alleviate traffic congestion that results from the growth of e-commerce we propose an approach in the city of Linz, Austria by relying on shared distribution centers from different companies. We develop two algorithms to find out the optimal location for the hubs and calculate the shortest path between locations. Results showed that in an urban environment, the implementation of hubs results in a reduction of the number of delivery vehicles. It reduces driving distances from hub to the customers, and also benefits the drivers that need to return home every day.Comment: 6 pages, 5 figures, 2 Tables, accepted for publication in the proceedings of the CISTI'2020 - 15th Iberian Conference on Information Systems and Technologie

The effect of sports massage on changes of muscle contraction after applied load

Title: The effect of sports massage on changes of muscle contraction after applied load Objectives: The aim of this work was to find out the scale of effect of sports massage on speed of muscle contraction of musculus vastus medialis and musculus vastus lateralis after previous exercise in form of squats and forward lunges. Methods: The research was realized in a form of Crossover design experiment and 7 probands took part in the research. Results were obtained by measuring muscle contraction velocity with tensiomyography method in the lab in department of physiology and biochemistry UK FTVS. We measured height and weight of every proband, after that they were randomly assigned either to control group or experimental group. In the control group we measured the speed of muscle contraction, after that the proband went through exercise in form of squats and forward lunges under certified supervision, then they had 5 minutes of passive rest and after the muscle contraction was measured again. The experimental group had a sports massage instead of 5 minutes rest. Results: The average muscle contraction velocity of musculus vastus lateralis of the control group in the second measurement was 25,47 ± 4,22 ms and the average muscle contraction velocity of the experimental group in the second measurement was...Název: Účinky sportovní masáže na změnu rychlosti kontrakce svalu po aplikované zátěži Cíle: Cílem práce bylo zjistit míru účinku sportovní masáže na rychlost kontrakce svalů musculus vastus medialis a musculus vastus lateralis po předchozí zátěži ve formě dřepů a výpadů vpřed. Metody: Výzkum byl proveden formou Crossover design experimentu, kterého se zúčastnilo 7 probandů. Výsledky byly získány měřením rychlosti kontrakce svalu metodou tensiomyografie v laboratoři na katedře fyziologie a biochemie UK FTVS. Každý proband byl změřen a zvážen, poté náhodně rozdělen buď do kontrolní skupiny, nebo experimentální skupiny. Kontrolní skupině byla změřena rychlost kontrakce svalů, poté provedli pod odborným dohledem zátěž, následovalo 5 minut pasivního odpočinku, po kterém proběhlo druhé měření rychlosti kontrakce. Experimentální skupina absolvovala to stejné s tím rozdílem, že místo 5 minutového odpočinku jim byla provedena kondiční masáž stehna. Výsledky: Průměrná rychlost kontrakce musculus vastus lateralis kontrolní skupiny ve 2. měření byla 25,47 ± 4,22 ms a průměrná rychlost kontrakce 2. měření experimentální skupiny byla 26,88 ± 2,92 ms. Experimentální skupina měla o 1,41 ± 3,66 ms pomalejší kontrakci s významností p = 0,389 (38 %). Průměrná rychlost kontrakce musculus vastus medialis kontrolní...Zdravotní TV a tělovýchovné lékařstvíFaculty of Physical Education and SportFakulta tělesné výchovy a sport

Mobile application able to analyse the Internet connections

The wide use of wireless networks in every aspect of our life has risen new challenges andsituations that affect the majority of the population around the globe. Issues such asinterferences between each network, fading or security attacks have to be bearded in mindwhen a wireless network is set up or when a user wants to establish connection with one.Therefore the goal of this study is the use and development of a mobile application that is ableto analyse the wireless networks that the device, a smartphone in this case. With theinformation obtained from the application the user should be able to find possible solution tothe challenges that may arise and to improve the quality of the service that he or she is usingin different environments with different characteristics. The testing of the application involvedthe obtainment of information in three different scenarios, the results of the three scenarioswere satisfactory. In all three scenarios the environment could be analysed successfully andsolutions could be given to improve the connectivity to each of the access points. <br /
