Ysis was performed on 17 men's water polo matches during the 2005-2006 season to evaluate the following technical and tactical parameters of the offensive play: frequency of occurrence of the actions; mean clock-time duration; mean number of players involved and passes; frequency of occurrence of the turnovers; and frequency of occurrence of the number, outcome, position, and type of the shots. All the indicators were analyzed in relation to even (i.e., equal number of offensive and defensive players), counterattack (i.e., higher number of offensive players than that of the defense), and power play (i.e., a team defending for 20 seconds without a player because of an exclusion foul) situations. A multivariate approach (multivariate analysis of variance) was applied to the playing situations (even, counterattack, and power play) as dependent variables and competition levels (Final Four of Euro League Championship, Serie A1 Championship, and Serie B Championship) as between factor (p < 0.05). Significant differences among competition levels emerged in (a) the frequency of occurrence of counterattack and power play actions, (b) the duration of even situations, (c) the mean number of players directly involved during power play actions, (d) the mean number of the passes during even and power play actions, (e) the frequency of occurrence of the shots during counterattack and power play actions, (f) the frequency of occurrence of goals during even actions, (g) the frequency of occurrence of shots originating from different zones of the court, and (h) the type of shots performed. The present results showed that the competition level has a relevant impact on the occurrence of technical and tactical indicators especially in relation to even, counterattack, and power play situations. Thus, notational analysis proved to be a valuable tool for better coaching through the interpretation of technical and tactical aspects of water polo in relation to its competition level....

Wondo competitions. Fifty-nine youth taekwondo athletes (43 boys and 16 girls; age range: 10–12 years; weight category range: 59 kg) with at least 2 years of taekwondo training consisting of three 90-minute training sessions for 3 d·wk−1 participated in this study. Thirty-seven matches (three 1-minute rounds, with 1-minute rest in between) were analyzed to verify the differences (p ≤ 0.05) in offensive and defensive actions in relation to gender (male, female), match outcome (winners, nonwinners), kicking leg (front, rear), and round (first, second, third). No difference emerged for gender and match outcome. With respect to defensive actions (8.4 ± 12.0%), youth athletes engaged more frequently (p < 0.0001) in offensive actions (91.6 ± 12.0%), which showed a significant decrease (p < 0.016) from the first round (42.3 ± 21.8%) to the second (33.1 ± 14.8%) and third (24.5 ± 16.0%) ones. Kicks performed with the rear leg (94.4 ± 7.8%) occurred more frequently (p < 0.0001) than those performed with the front leg (5.6 ± 7.8%). In considering that a high level of coordination is required to perform front-leg kicks and defensive actions necessitate a high level of tactical skills, these findings might indicate a not-yet complete attainment of fundamental coordinative capabilities in 10- to 12-year-old athletes, independently of match outcome. To enhance coordination capabilities in youth athletes, coaches are recommended to structure their training including skill-ability and sport-ability drills....

Purpose: To anticipate outstanding athletic outcomes, the selection process of elite athletes simultaneously considers psychophysiological and technical parameters. This study aimed to investigate whether selected and nonselected athletes for the Italian national taekwondo team could be discriminated by means of sportspecific performances and psychophysiological responses to training.Participants: 5 established Italian national athletes and 20 elite Italian taekwondo black belt athletes (9 women, 16 men; age 23.0 ± 3.1 y; body mass 67.0 ± 12.1 kg).Methods: To update the Italian national-team roster, the 20 elite athletes participated in a 1-wk selection camp (7 training sessions). Selected athletes (n = 10) joined established national athletes during the following 3-wk national training period (7 training sessions/wk). During the 1-wk selection camp, differences (P < .05) between selected and nonselected athletes in performances, heart-rate responses, blood lactate accumulation [La], subjective ratings of perceived exertion (session RPE), and mood were examined. During the 3-wk national training period, differences (P < .05) in mood between selected and established national athletes were investigated.Results: With respect to nonselected athletes, selected athletes responded better to training in terms of session RPE (P = .047) and [La] (P = .046). No difference in performance and mood between subgroups emerged. After the 3-wk national training period, differences (P = .035) emerged for confusion, with decreases in the established national athletes and increases for recently selected athletes.Conclusions: Session RPE and [La] seem to be more effective than psychological measures in discriminating between elite taekwondo athletes. Evaluation of mood could be effective in monitoring athletes’ response to national training.

G semifinal and final matches (three 1.5-minute rounds, with 1-minute rest in between) of the 2010 Italian Taekwondo Cadet (age 13–14 years) Championship (adolescent boys, n = 40; adolescent girls, n = 28) in relation to gender (adolescent boys and girls) and grouped weight division (light, middle, and heavy) of athletes. Regardless of gender, grouped weight division, round, and tournament stage, differences (p < 0.001, effect size range: 1.92–3.02) emerged for frequency of occurrence of combat phases (F: 42.4 ± 0.5%; NF: 44.5 ± 0.7%; ST: 13.1 ± 0.9%) and their mean duration (F: 2.8 ± 1.0 seconds; NF: 6.5 ± 1.8 seconds; ST: 13.7 ± 5.0 seconds). A 1:2 F to NF ratio was found, whereas a 1:3 ratio emerged when F was considered in relation to the sum of NF and ST. During F phase, 5 ± 1 tactical movements and 4 ± 1 technical exchanges were performed, lasting 0.6 ± 0.1 seconds and 0.7 ± 0.1 seconds, respectively. These findings mirrored the intermittent nature of youth combat, characterized by a high occurrence of tactical movements and technical exchanges during F phase. The lack of differences for round and tournament stages indicates a limited tactical capability of young athletes in adopting specific match strategies, independently from gender and weight divisions of the athletes. To prepare young athletes to handle the technical-tactical demands of the match, coaches could include 7–9 circuit stations of specific taekwondo sequences of attack and counter attack techniques....

The purpose of this study was to define the technical and tactical profiles of official youth taekwondo competitions played under the most recent rules of the International Taekwondo Federation. Tactical actions (i.e., attack, defense, and block), technical executions (from 1- to 4-point scores), kicking legs (i.e., front/rear and right/left), and overall technical effectiveness were investigated in relation to match outcome of semifinal and final competitions (n = 50) of youth (aged 13-14 years) black belt athletes during the Italian Taekwondo Cadet Championship. Differences (p < 0.001) were found among all action typologies (Attack: 50.9 ± 2.2%; Defense: 27.7 ± 1.5%; Block: 21.3 ± 1.6%), with winners showing fewer (p = 0.005) offensive actions and more (p = 0.001) defensive actions with respect to non-winners. Independently from match outcome, technical exchanges showed differences (p < 0.001) for technical executions. Winners resulted more efficient (p < 0.001) for both technical and tactical variables. In general, these findings showed that Cadets tend to adopt an offensive strategy. In considering that the adoption of the new electronic system requires athletes to execute correct technical actions to have a score assigned, coaches should emphasize the effectiveness of scoring techniques and help athletes to effectively improve their defense and counterattack capabilities.
