Ponències castelleres

En el marc del 70è aniversari de la Colla dels Castellers de Vilafranca, el proppassat 14 d’abril al Fòrum Ramonet van organitzar-se unes ponències castelleres al voltant de la forma física i la seguretat en els castells. Els tres ponents van ser el Dr. Jordi Porta, el Dr. Alfred Irurtia i el Dr. Jaume Rosset.

Tant l’Escola Catalana de Cineantropometria com el propi GRCE van estar representats per dos dels seus membres, Dr. Jordi Porta i el Dr. Alfred Irurtia. Ambdós professors varen presentar les seves respectives ponències davant d’una bona part de la representació castellera del municipi de Vilafranca així com d’altres indrets de Catalunya. Posteriorment, es va organitzar una taula rodona en que tothom va tenir l’oportunitat d’interactuar i plantejar preguntes o reflexions als ponents.

Els castells del segle XXI: què es necessita per assolir el 3D11FMP i 9 NETS – Dr. Jordi Porta (jordiportamanz.49@gmail.com)

Nens o nenes, nois o noies, homes o dones: quins són més eficients per fer castells. –  Dr. Alfred Irurtia (airutia@gencat.cat)

Sailing science with FNOB – Barcelona World Race

la-fnob-potencia-su-programa-de-investigacion-junto-a-los-principales-actores-cientificos.jpg

The Fundació Navegació Oceànica Barcelona (FNOB) continues to foster scientific research during the Barcelona World Race (BWR) through an initiative provisionally called FNOBLab.

Ocean sailing around-the-world regattas, such as the BWR, are unbeatable test platforms for scientific research projects that can impact society, both in the environmental field and in the mental and physical performance .

The projects have been divided into two areas, the first oriented to the human factor and its physiological, physical and psychological performance in extreme conditions, and the second, focused on the health of the oceans.

At this moment the entities participating in the meetings are: University of Barcelona (UB); Center for Research in Biomedical Engineering (CREB) of the Polytechnic University of Catalonia (UPC); National Institute of Physical Education of Catalonia (INEFC); IQS-Instituto Químico de Sarriá, founding member of the Ramón Llull University; Institut de Ciències del Mar (ICM) of the Higher Council for Scientific Research (CSIC); Leitat Technological Center; Eurecat, Technological Center of Catalonia; Centre d’Alt Rendiment Sant Cugat (CAR); Gastrocultura Mediterrània; and Fundación Estivill Sueño, which have already agreed to carry out a list of desirable projects that may be part of the next edition of the Barcelona World Race.

The GRCE–INEFC will lead and collaborate with CREB–UPC in two projects focused on the bioenergetics, heart neuromodulation, external and internal physical load and data science of ocean sailing during the 2019 BWR regatta, starting on January 12, 2019.

New paper in International Journal of Sport Physiology and Performance

The paper entitled “Dynamics of the metabolic response during a competitive 100-m freestyle in elite male swimmers“, by Philippe Hellard, Robin Pla, Ferran A. Rodríguez, David Simbana and David B. Pyne, has been published in the International Journal of Sports Physiology and Performance (JCR IF: 2.654).

The study compared the dynamics of V̇O2, blood lactate ([La]b), total energy expenditure (Etot), and contributions of anaerobic alactic (Ean,al), anaerobic lactic (Ean,lac), and aerobic (Eaer) metabolic energy pathways over four consecutive 25-m laps (L0-25, L25-50, L50-75, L75-100) of a 100-m maximal swim. Fifty junior and senior elite swimmers performed 100 m at maximal speed, and then three trials (25, 50 and 75 m) at the same pace as that of the 100 m. The estimated energetic contributions (%Etot) for the 100-m trial were: Eaer 44 ± 7%, Ean,al 33 ± 4%, Ean,lac 23 ± 7%. Faster swimmers were characterized by higher peak V̇O2, and less time to reach the highest V̇O2 at ~50 m of the 100-m swim. Anaerobic qualities become more important with age.

This project was carried out in collaboration with the Research Department of the  French Swimming Federation, the Laboratoire for Sport, Expertise, Performance (INSEP),  the Centre d’Études des Transformations des Activités Physiques et Sportives (CETAPS), University of Rouen Normandy, the Research Institute for Sport and Exercise (University of Canberra), and the Physiology department of the Australian Institute of Sport.

New in Entropy

The paper entitled “Assessment of heart rate variability during an endurance mountain trail race by multi-scale entropy analysis“, authored by Montserrat Vallverdú, Aroa Ruiz-Muñoz, Emma Roca, Pere Caminal, Ferran A. Rodríguez, Alfredo Irurtia and Alexandre Perera has been published in Entropy  (JCR IF: 1.821).

The study analyzed the heart rate variability (HRV) response to high-intensity exercise during a 35-km mountain trail race to ascertain whether fitness level could influence the autonomic nervous system modulation. Time-domain, frequency-domain, and multi-scale entropy indexes (MSE) were calculated for 11 mountain-trail runners. Many changes were observed, mostly related to exercise load and fatigue. The time-domain, frequency-domain, and MSE indexes were also able to discriminate faster from slower runners, mainly in the more difficult and in the final stages of the race. These findings suggest the use of HRV analysis to study cardiac function mechanisms in endurance sports.

This project was carried out in collaboration with ESAII, Centre for Biomedical Engineering Research, and Centro de Investigación Biomédica en Red de Bioingeniería, Biomateriales y Nanomedicina (CIBER-BBN), Universitat Politècnica de Catalunya (UPC).
