Elektronisko vārdnīcu lietojumprogrammu viedtālruņos izmantošana studiju procesā
2017
Pētījuma mērķis bija izpētīt elektronisko vārdnīcu lietotnes un kā to izmantošana var ietekmēt studiju procesu. Mērķa sasniegšanai tika izvēlētas divas pētījuma metodes – kontentanalīze un verbālais protokols. Ar kontentanalīzes palīdzību, tika noskaidrots vārdnīcu lietotņu: Google Translate, Merriam – Webster Dictionary, iTranslate, Oxford Advanced Learner Dictionary, Saruna Tulkotājs izmantošanas iespējas un to funkcijas. Otrajā pētījuma metodē tika pētīta šo lietojumprogrammu lietojamība, piedaloties 3 studentiem. Pētījuma gaitā tika konstatēts, ka lietotnes ir ātrāks, ērtāks veids, kā iztulkot vārdu vai atrast definīciju. Pētījumā iegūtie rezultāti ļāva noskaidrot vārdnīcu lietotņu dažā…

Development of an individualized familiarization method for vertical jumps
2013
OBJETIVO: Propor um método de familiarização individualizado para saltos verticais e verificar o seu efeito na variabilidade intrassujeito. MÉTODOS: Cinquenta e três homes (média ± DP; idade 23,5 ± 3,3 anos; estatura 1,76 ± 0,08 m; massa 72,8 ± 8,6 kg; percentual de gordura 12,9 ± 5,2%) realizaram sucessivos saltos até atingir o nível de estabilidade proposto. Após 48 h este processo era repetido e a estabilidade entre dias era verificada, se necessário, mais sessões eram realizadas. O nível de estabilidade foi determinado por um teste z, com intervalo de confiança de 95%. Após o processo de familiarização, duas sessões experimentais adicionais foram realizadas para determinar a confiabilid…
Hypovitaminosis D in Young Basketball Players: Association with Jumping and Hopping Performance Considering Gender
2021
This study aimed to verify whether a group of young well-trained basketball players presented deficiencies in vitamin D concentration, and to analyze whether there was an association between vitamin D concentration and jumping and hopping performance. Gender differences were considered. Twenty-seven players from an international high-level basketball club (14 female, 16.00 ± 0.55 years
Reliability of measurements during countermovement jump assessments: Analysis of performance across subphases
2020
The aim of this study was to examine the reliability of performance measures in the different phases and sub-phases of the countermovement jump (CMJ). Seventeen male athletes competing at a regional level completed 204 valid trails consisting of the execution of maximal hands-on-waist CMJs performed on a force platform. The vertical ground reaction force (VGRF) data obtained at a sampling frequency of 1000 Hz were used to calculate performance-derived variables and determine key points and jump sub-phases. The relative reliability of 92 variables was assessed using the intraclass correlation coefficient (ICC) from a two-way mixed effects model analyzing the time, force, power, velocity, and…
Concentric force enhancement during human movement
2001
In order to understand the possible mechanisms contributing to enhanced concentric performance in stretch-shortening cycle exercises in vivo the present study examined knee extension torque, EMG activity and fascicle length of the vastus lateralis muscle in maximal and submaximal human movements. Maximal concentric knee extensions (120 s-1) were done after pre-stretch and pre-isometric conditions by nine volunteers. During shortening at the knee angle of 115 (180 = extended) the knee extension torque was found to be greater in pre-stretch condition (272 vs. 248 Nm, p < 0.05) although the torque level prior to shortening was smaller than in pre-isometric condition (268 vs. 314 Nm, p< 0.05…
A systematic review to determine reliability and usefulness of the field-based test batteries for the assessment of physical fitness in adolescents -…
2015
The aim of the present review is to investigate the main field-based tests, used alone or included in sport or fitness batteries, for the assessment of health- and skill-related physical fitness components in adolescents. Different scientific databases were searched through using the selected key words related to physical fitness and its components for adolescence. The search focused on original articles and reviews/meta-analyses using valid, reproducible and feasible tests that fit within the school environment. A total of 100 scientific manuscripts were included in the qualitative synthesis. The present systematic review pointed out 5 fitness tests that well adapt to the evaluation of the…
Futbola sporta kluba informācijas sistēma
2022
Darba mērķis ir dot iespēju futbola kluba līdzjutējiem ērti sekot līdzi savam iecienītākajam klubam, jo visa nepieciešamākā informācija tiks apkopota vienuviet. Lietotāji varēs uzzināt informāciju par spēlēm un ziņām, apskatīt komandas sastāvu un galeriju ar fotogrāfijām, kā arī pasūtīt biļetes uz spēli. Administrators ir atbildīgs par sistēmas saturu.
Effects of an experimental short-time high-intensity warm-up on explosive muscle strength performance in soccer players: A pilot study.
2022
Objective: This study aimed to evaluate the effects of an experimental short-time warm-up consisting of a small number of intermittent high-intensity sprints on explosive muscle strength performance in soccer players and to identify recovery times after performing the sprints. Furthermore, we evaluated the reliability of a smartphone app in jumping performance.Methods: Twenty male soccer players were given the following tests: 1) the counter-movement jump (CMJ) test with the Microgate system, 2) the counter-movement jump (CMJ) test with the MyJump smartphone app, and 3) the handgrip strength test. The experimental short-time high-intensity warm-up was carried out 1 week after test administr…
Iegultās iekārtas un programmatūra veselības datu pārraudzībai rehabilitācijas laikā
2015
Bakalaura darbs apskata sekojošu problēmu: pacientu veselības rādītāju pārraudzība rehabilitācijas iziešanas laikā. Autors apskata menisku bojājumu pēcoperāciju rehabilitācijas procesu ar mērķi definēt pārraudzībai nepieciešamus veselības rādītājus. Pirms risinājuma izstrādes tika veikta veselības speciālistu un bijušo pacientu intervēšana. Tas palīdzēja autoram aplūkot un izanalizēt situāciju no abām pusēm – saprast kādas grūtības pastāv fizioterapeitu darbā un atrast ar kādām problēmām saskarās pacienti pēc ceļa locītavas operācijas. Darba ietvaros tika veikta esošo risinājumu analīze ar mērķi aplūkot izmantotas tehnoloģijas un atrast šo izstrāžu priekšrocības un nepilnības. Apskatot un s…
