PILOT WORK ON EVALUATION OF WOMEN WATER POLO TACTICS PATTERN
Full text linkIn water polo lacks a codified methodology for tactics training, which is thus only left to coach’s discretion.
Nine women water polo matches, during season 2011/2012 (Italian female Serie A1), have been analyzed by a
water polo coach, helped by a statistician and a performance analyst. Purpose of the analysis process was to identify
single events during the matches, to examine the tactical pattern implemented in this events, to obtain by the coach an
evaluation on tactical pattern compliance and then to put this compliance in relation to event’s outcome. Aim of the
work is to verify the efficacy of different attack patterns, when they were well-performed, in order to create a codified
methodology for teaching water polo through tactics.
The research approach is integrated and consists of 3 distinct methods: case study (9 matches of the Italian Serie
A1 Women's Championship, season 2011/2012, played by the Volturno sc) for the analysis of matches, action research
method for coach contribution, and theoretical-argumentative method to deduce a theoretical framework in which
define the data processing.
The research team examined matches with Dartfish TeamPro, isolating single keyframes relative to attack
events, identifying the implemented attack pattern, then the coach expressed an evaluation on attack pattern compliance.
The results showed a general efficacy of tactical patterns (when they are well performed), but showed significant
differences within correlation coefficients of single patterns, confirming the need for developing a common
methodology for teaching waterpolo through tactics
The physical effort required from professional football players in different playing positions
Full text linkThe purpose of this study is to examine the physical effort required at professional football players (Italian Championship) in relation to the examination of a series of friendly matches at different times of the year, compared to their role, using the technology of GPS, for finalizing the training to improve the sport performance. The activities of players were monitored using GPS technology with a sampling rate of 10 Hz. The total distance covered, distances with different speed and accelerations were analyzed in relation to five different roles: (CD) central defenders, (FB) full-backs, (M) midfielders, (AM) advanced midfielders and (A) attackers. Players activities were monitored using GPS technology with a sampling rate of 10 Hz. Total distance covered, distance at different speeds and accelerations were analyzed in relation in five different roles: (CD) central defenders, (FB) full-backs, (M) midfielders, (AM) advanced midfielders and (A) attackers. The maximum covered distance (over 10 km) during a friendly match was reached by the third (FB), midfielders (M) and advanced midfielders (AM); The same ones have covered, too, the greatest distances in high-intensity running (> 16 km/h); instead, the attackers and central defenders covered the distance in high power. The full-backs (FB) and Advanced Midfielders (AM) have producted high acceleration and deceleration compared to other roles, while midfielders (M) have developed greater metabolic power. Finally, the end-of-season results were compared with the data gained at the beginning of the year and important differences between the various roles were noted
Evaluation of incidence of ball-handing on swimming intensity in female water polo
Full text linkThe purpose of the present study is to verify the incidence of ball handling in swimming intensity in water polo,
in order to obtain useful indication in coaching. The research method is integrated and consists of action research for
coach contribution by training and evaluation, and theoretical-argumentative to deduce a framework in which define the
data processing. Eleven well-trained competitive athletes were recruited and asked to swim 5 x 20-m, one time with
ball, and one time without ball. This test was repeated three times.
For each swimmer was calculated the mean and standard error of times per test, both with and without the ball.
Analysis was conducted individually for each athlete, and in total for each test. The results, trough confrontation of
means of times, reveals a high variability, and indicate a non mechanical incidence of ball handling on swimming
intensity. Reading this results in correlation to athletes anamnesis reveals that incidence of ball-handling is significant
only in athletes who have a swimming-oriented athletic history, but there are not significant differences in times for
athletes who have a water polo oriented athletic history.
The results show as this study can help the coach to train the team for improving the analyzed skills in different
mode, creating a methodological system training to enhance the performance.
Coaches are suggested to carefully monitor swimming rhythm during trials, and to increment ball-handling in
every training condition
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
PLuRALE project - Physical LiteRAcy in Lifelong Education
No full textThe concept of physical literacy is rapidly gaining consensus across the globe. Currently, physical literacy is not only seen as the result of physical education but as a concept of health and well-being throughout life, and is therefore gaining importance in educational, medical, psychological and social field. Physical literacy, in other words, seems to define a common denominator and a common sense horizon to a set of studies (and practices) that, in the international context, acquire a wide variety of denominations: sport science, exercise science, human performance, movement science, human kinetics, kinesiology, kinanthropology, athropomotorics, anthropokinetics, anthropokinesiology, health, physical education, physical culture, recreation, leisure studies, coaching, athletic training, adapted physical education, sport management (Čustonja, Milanović, & Sporiš, 2009). The work intends to present a unitary approach to the concept of literacy, developing its various and complementary declinations. The shift from skills to literacy implies further advancement towards a holistic conception of the human being and its interaction in the world as a key to a full and satisfying life (Whitehead, 2010). From this perspective, the paper deals with "old" and new literacies, investigating how the current situation challenges the idea of different "literacies" as a different set of skills in various fields of knowledge in favor of a unitary, but more global and complex, meaning of literacy as the ability to "read" and "write" our own living environment. These are the premises of the PLuRALE project - Physical LiteRAcy project in Lifelong Education, starting at the University of Salerno, presented at the end of the pape
