The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power …
2021
The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1+2.6 years, 100 m performance: 11.5+0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4]…
An Innovative Power Line Communication solution For Medium Voltage Smart Grids Applications
2018
This paper summarizes the authors research activity concerning the design, modeling and experimental characterization of a new coupling system for medium voltage (MV) narrow band power line communications (NB-PLC). The proposed solution has been patented by authors and it exploits the capacitive divider of voltage detecting systems (VDSs) normally used to reveal the mains voltage presence, thus avoiding the use of dedicated MV couplers. In the following, the modeling of the VDS capacitive divider is presented and the interface card design is described, based on simulation of the whole PLC transmission channel. Laboratory tests are also presented. Finally, the results are shown of an on-fiel…
I Symposium of Elite Performance in Combat Sports
2017
This report presents a summary of the I Symposium of Elite Performance in Combat Sports held in Madrid, May 27, 2017. The symposium, organized by the Faculty of Sport Sciences-INEF of the Polytechnic University of Madrid, aimed to bring science closer to practice. A panel of highly successful athletes involved in karate, fencing, and taekwondo shared their experiences. The speakers presented crucial topics for an optimal preparation and high level performance such as strength training, sport psychology, brain maturation, sports nutrition, competition planning, sport injuries, and perceptual-decision making training.
Prezentācijas lai attīstītu vidusskolas skolēnu publiskās uzstāšanās prasmes
2019
21. gadsimts prasa, lai ikviens būtu komunikabls un pašpārliecināts. Prezentācijas ir labs līdzeklis, uz ko balstīties situācijās, kad skolēni nejūtas pašpārliecināti uzstājoties. Diplomdarba tēma ir prezentācijas lai attīstītu vidusskolu audzēkņu publiskās uzstāšanās prasmes. Teorētiskā daļā ir aprakstīti vidusskolas skolēni 21. gadsimta skolā, viņu uzstāšanās prasmes, uzstāšanās prasmju attīstība prezentāciju laikā un prezentāciju daudzveidība. Praktiskajā daļā autore analizē anketas par prezentācijām kā vidusskolas audzēkņu uzstāšanās prasmju attīstītājām. Rezultāti liecina, ka studenti un angļu valodas skolotāji novērtē prezentācijas kā uzstāšanās prasmju attīstītājas. Pētījums apstipri…
Reasoning of using causation and effectuation logic : implications on start-up performance and internationalization
2018
New start-up companies are the basis for expansive companies. Expansive companies are extremely important for employment and for business growth. For this reason, it is important to know the processes how start-up companies are built up. In this research, the relations between prior entrepreneurial experience, prior international experience, effectuation and causation, financial performance and degree of internationalization were studied among the Finnish knowledge intensive business services (KIBS) start-up companies. The research utilized mixed methods and comprised of two parts, qualitative and quantitative parts. The former part included setting the research propositions based on the li…
Modelo de competencia docente del profesor de medicina en la UNAM
2011
Resumen basado en el de la publicación Título, resumen y palabras clave en español e inglés Disponible la versión en inglés Se presenta un modelo de competencia docente del profesor de medicina. Fue generado a partir de un modelo conceptual preexistente: dicho modelo se sometió al juicio de expertos quienes seleccionaron las competencias de mayor impacto, construyéndose un perfil de competencias. Se generó un instrumento basado en la opinión de los estudiantes y otro de autoevaluación, siendo ambos validados por 18 expertos en evaluación y aplicándose a 2281 estudiantes y 107 profesores. Asimismo, se obtuvo un comportamiento psicométrico adecuado que permitió establecer un modelo acorde a l…
Learning from Implicit Learning Literature: Comment on Shea, Wulf, Whitacre, and Park (2001)
2003
International audience; In their analysis of complex motor skill learning, Shea, Wulf, Whitacre, and Park (2001) have overlooked one of the most robust conclusions of the experimental studies on implicit learning conducted during the last decade--namely that participants usually learn things that are different from those that the experimenter expected them to learn. We show that the available literature on implicit learning strongly suggests that the improved performance in Shea et al.'s Experiments 1 and 2 (and similar earlier experiments, e.g., Wulf & Schmidt, 1997) was due to the exploitation of regularities in the target pattern different from those on which the postexperimental intervi…
Restoration of High Frequency Auditory Perception After Robot-Assisted or Manual Cochlear Implantation in Profoundly Deaf Adults Improves Speech Reco…
2021
Background and Purpose: Robot-assisted cochlear implantation has recently been implemented in clinical practice; however, its effect on hearing outcomes is unknown. The aim of this preliminary study was to evaluate hearing performance 1 year post-implantation whether the electrode array was inserted manually or assisted by a robot.Methods: Forty-two profoundly deaf adults were implanted either manually (n = 21) or assisted by a robot (RobOtol®, Collin, Bagneux, France) with three different electrode array types. Participants were paired by age, and electrode array type. The scalar position of the electrode array in the cochlea was assessed by 3D reconstruction from the pre- and post-implant…
Low-protein vegetarian diet does not have a short-term effect on blood acid¿base status but raises oxygen consumption during submaximal cycling
2012
Background. Acid–base balance refers to the equilibrium between acids and bases in the human body. Nutrition may affect acid–base balance and further physical performance. With the help of PRAL (potential renal acid load), a low-protein vegetarian diet (LPVD) was designed to enhance the production of bases in body. The aim of this study was to investigate if LPVD has an effect on blood acid–base status and performance during submaximal and maximal aerobic cycling. Methods. Nine healthy, recreationally active men (age 23.5 ± 3.4 yr) participated in the study and were randomly divided into two groups in a cross-over study design. Group 1 followed LPVD for 4 days and group 2 ate normally (ND) …
