Time-motion analysis and Decision Making in Female Judo Athletes during Victory or Defeat at Olympic and Non-Olympic Events: Are Combat Actions Really Unpredictable?

Olympic and Paralympic Games Rio 2016

“…These findings can be attributed to several factors, such as a high technical variety, tactical attitude or even physiological aspects, since the competitive level is very similar among them. Miarka et al (2016b) found that female winners have higher attack activities compared to losers, but these attack activities did not always result in scores in the Olympic Games. This confirms that the performance levels of the medallists are very similar.…”

“…The Olympic athletes produced greater scores in the matches (Table 2). This difference can probably be explained by the observation that the Olympic athletes have shown a longer timesequence of attacks (Castarlenas, & Planas, 1997;Miarka, et al, 2016b) and a higher technical variation than the Paralympic athletes (Adam, et al, 201;Franchini, Sterkowicz, Meira Jr., Gomes, & Tani, 2008;Gutiérrez-Santiago, et al, 2012;Sterkowicz, & Franchini, 2000). Similarly to the previous finding regarding the all-female team, the Paralympic medallists presented fewer shidos per match compared to the Olympic athletes, probably because of different combat features, which were mainly due to the necessity of kumi-kata during the match in the Paralympic athletes.…”

“…However, the Olympic athletes lost more matches to the shido than the Paralympians. This can be explained by the temporal difference between the two scenarios; in the Paralympic matches the time of pause represents 54% of the total time of the combat and the effort time is only 45.1% (Gutiérrez-Santiago, et al, 2012), while in the Olympic matches, the time of pause is close to 31% and the effort time (combat time) is 67% (Miarka, et al, 2016b). Therefore, it has been suggested that the Olympic judokas are more active during the combat with fewer pauses than the Paralympians, possibly resulting in a higher number of scores and penalties.…”

“…During the match competition, judo athletes are constantly searching to throw or finalize the opponents (Franchini, et al 2013a;Miarka, et al, 2016b;Sterkowicz, Sacripanti & Sterkowicz-Przybycien, 2013). Different scores can be attributed regarding the type of the opponent's throwing to the ground, immobilization time or finalization.…”

Making Decisions and Motor Actions with Technical Biomechanical Classifications in Male Judo Weight Categories

“…Following time motion analysis, judo combats present irregular activity and pause patterns (Lech et al, 2015;Miarka et al, 2015;Santos et al, 2018;Maszczyk et al, 2018Maszczyk et al, , 2020. Previous studies have revealed variables which influence motor actions in judo combats, including expertise (Drid et al, Journal of Human Kinetics -volume 72/2020 http://www.johk.pl 2015), the competitive outcome (Escobar-Molina et al, 2014;Maszczyk et al, 2018Maszczyk et al, , 2020, the competitive level (Miarka et al, 2016(Miarka et al, , 2016a, weight categories (Brabec et al, 2019;Sterkowicz et al, 2013;Sterkowicz-Przybycien et al, 2017), the judging system and the effect of home advantage (Brito et al, 2017). Furthermore, age effects have been observed in the time dedicated to the approach, gripping, attack, groundwork and pause phases during judo competition (Miarka et al, 2014;Santos et al, 2018).…”
