Prediction of Kick Count in Triathletes during Freestyle Swimming Session Using Inertial Sensor Technology
Monitoring sports training performances with automatic, low cost, low power, and ergonomic solutions is a topic of increasing importance in the research of the last years. A parameter of particular interest, which has not been extensively dealt with in a state-of-the-art way, is the count of kicks during swimming training sessions. Coaches and athletes set the training sessions to optimize the kick count and swim stroke rate to acquire velocity and acceleration during swimming. In regard to race distances, counting kicks can influence the athlete’s performance. However, it is difficult to record the kick count without facing some issues about subjective interpretation. In this paper, a new method for kick count is proposed, based on only one triaxial accelerometer worn on the athlete’s ankle. The algorithm was validated on data recorded during freestyle training sessions. An accuracy of 97.5% with a sensitivity of 99.3% was achieved. The proposed method shows good linearity and a slope of 1.01. These results overcome other state-of-the-art methods, proving that this method is a good candidate for a reliable, embedded kick count
Notational Analysis of Wheelchair Paralympic Table Tennis Matches
Paralympic table tennis is the third largest paralympic sport for the number of players.
Performance analysis was conducted for the rally duration and interval and impact of serve, whilst
none investigated the shots distribution among classes of physical impairment. Therefore, the
purpose of this study was to conduct a notational analysis of international competitions in relation to
the wheelchair classes. Five matches for each wheelchair class (C1-to-C5) were evaluated from 20 elite
male right-handed players. Both players for each match were analyzed for the following performance
indicators: strokes type, the area of ball bouncing, and the shots outcome. Backhand shots were
the most used technique for all classes. The most used strokes for C1 players were backhand and
forehand drive and backhand lob, while for C5 players they were backhand and forehand push and
backhand topspin. Similar shots distribution was registered for C2-to-C5 players. The central and
far-from-the-net zone was mainly reached by the serve for all classes. Errors shots were similar in all
classes, whilst winning shots were more frequent in C1. The current notational analysis provided a
meaningful performance modelling of indicators for coaches and athletes that can be used to design
training programs for each class
Evolution led humans to bipedalism, but we live in a sedentary society: Will “Sunday running” protect us from NCDs at no cost?
Evolution led humans to bipedal stance and movement. However, we live in a sedentary society that strongly challenges our willingness to be physically active. We (mis)understand that being at least a Sunday runner could protect us from sedentary-related diseases, but what if this compromises the healthier life expectancy anyway? Citing Paul Gauguin, we know where we come from and what we are, the question arises about where we are going. And also, how
El rock y el hombre : La construcción del estereotipo masculino en el campo visual
El eje de investigación del presente proyecto contempla los discursos estereotipados en la publicidad audiovisual. Tomando como caso de estudio la publicidad “Rock The Pasta” de Matarazzo, se analiza la imagen de masculinidad presentada, teniendo en cuenta el rol que cumplen los medios de comunicación en la construcción y reproducción de estereotipos.
El estudio realizado abarca la Provincia de Buenos Aires, Argentina, años 2014 y 2015. A través de la recopilación y análisis de aportes de distintos referentes teóricos, con una mirada transdisciplinar que involucra nociones psicológicas, sociológicas y relacionadas al estudio de la comunicación, y a partir del empleo de herramientas de comprobación -encuesta vía web dirigida a hombres-; este proyecto analiza cómo afecta a la sociedad el estereotipo de masculinidad utilizado en los medios de comunicación, su relación con la música de rock, y en qué medida representa al hombre actual.
El proyecto busca dejar en claro que, si bien la utilización de estereotipos es inevitable en la construcción discursiva en el campo de la comunicación, se debe realizar un uso responsable de ellos en el ámbito disciplinar, evitando connotaciones negativas.Mesa F.Facultad de Bellas Arte

Physical Activity and Redox Balance in the Elderly: Signal Transduction Mechanisms
Reactive Oxygen Species (ROS) are molecules naturally produced by cells. If their levels are
too high, the cellular antioxidant machinery intervenes to bring back their quantity to physiological
conditions. Since aging often induces malfunctioning in this machinery, ROS are considered an
effective cause of age-associated diseases. Exercise stimulates ROS production on one side, and the
antioxidant systems on the other side. The effects of exercise on oxidative stress markers have been
shown in blood, vascular tissue, brain, cardiac and skeletal muscle, both in young and aged people.
However, the intensity and volume of exercise and the individual subject characteristics are important
to envisage future strategies to adequately personalize the balance of the oxidant/antioxidant
environment. Here, we reviewed the literature that deals with the effects of physical activity on
redox balance in young and aged people, with insights into the molecular mechanisms involved.
Although many molecular pathways are involved, we are still far from a comprehensive view of the
mechanisms that stand behind the effects of physical activity during aging. Although we believe that
future precision medicine will be able to transform exercise administration from wellness to targeted
prevention, as yet we admit that the topic is still in its infancy
