The temporal structure of judo bouts in visually impaired men and women

Abstract

The aim of this study was to determine the temporal structure of judo bouts in visually impaired men and women (n = 117 judokas in the senior category; 92 men and 25 women). We developed a data recording system based on the temporal parameters of judo and applied it to a broad sample of international bouts (n = 219; 184 between men and 35 between women). The descriptive analysis of frequency of occurrence revealed that most of the bouts ended before the time-up bell sounded (81% men/74% women). Other defining features are shown in the following mean values (for men/women): the total bout time was 266/242 s; the total time paused was 158/172 s; the total time spent in standing combat was 82/54 s (P = 0.008), while that of floor combat was 60/84 s (P = 0.021); each bout had 6.9/5.7 paused sequences with a duration of 19.6/21.1 s, and 12.4/11.7 active sequences with a duration of 22/19.7 s. The sequential analysis by means of T-patterns (THEME) confirmed that the temporal structure of judo is not the same for men and women, thereby highlighting the need for a range of training methods matched to the needs of visually impaired competitors.

The Specificity of Observational Studies in Physical Activity and Sports Sciences: Moving Forward in Mixed Methods Research and Proposals for Achieving Quantitative and Qualitative Symmetry

“…Numerous examples have been described in the literature, particularly in recent years, and have been applied to a wide range of sporting contexts, including motor skill analysis (Castañer et al, 2009), physical activity (Castañer et al, 2016b), middle- and long-distance races (Aragón et al, 2015, 2017), basketball (Fernández et al, 2009), soccer (Jonsson et al, 2006; Castañer et al, 2016a, 2017a; Casal et al, 2017; Diana et al, 2017), judo (Gutiérrez-Santiago et al, 2011), hockey (Hernández-Mendo and Anguera, 2002), futsal (Lapresa et al, 2013b), and kinesics (Castañer et al, 2013). Ad-hoc instruments have been shown to be equally effective in amateur (Arana et al, 2013) and elite (Barreira et al, 2014) sport.…”

Olympic and Paralympic Games Rio 2016

“…In the Olympic judo matches, the ratio effort: pause is close to 2:1 or 3:1 (Miarka, Julio, Del Vecchio, Calmet & Franchini, 2010;Miarka, et al, 2012;, while in the Paralympic matches shorter work sequences (13 seconds) and longer breaks (20 seconds) have been observed (effort: pause ratio of 1:2) (Gutiérrez-Santiago, Prieto, Camerino & Anguera, 2011; Gutiérrez-Santiago, Cancela, Zubiaur & Ayán, 2012). This difference is possibly because in the Paralympic combat the athlete initiates the match with his/ her hands positioned in the judogi of the opponent (kumi-kata) and this procedure is repeated every time the combat has been interrupted (Gutiérrez-Santiago, et al, 2011).…”

“…Thus, the first aim of this study was to compare the scores, penalties and efficiency indexes in male and female judo athletes between the Olympic and Paralympic Games Rio 2016 (general and medal-lists); the second aim was to identify which variable (score or penalties) determined the outcome (winner) of the matches in both the Olympic and Paralympic Games. We hypothesized that: i) the Olympic medallist athletes in both male and female teams will have better scores and efficiency indexes, as well as a higher number of penalties, compared to the Paralympic medallist athletes, due to technical-tactical differences during competition (e.g., work rate and breaks during the matches) (Gutiérrez-Santiago, et al, 2011; ii) scores (ippon, waza ari/yuko) will determine the outcome of the matches instead of the penalties in the Olympic and Paralympic Games.…”

“…T-pattern detection has been used in many sports (Jonsson et al, 2010), including, in recent years, fencing (Tarragó et al, 2015;Tarragó et al, 2016) and other combat sports (Camerino, Prieto, Lapresa, Gutiérrez, & Hileno, 2014;Gutiérrez-Santiago, Prieto, Camerino, & Anguera, 2011a, 2011bLapresa, Ibáñez, Arana, Amatria, & Garzón, 2011;.…”
