Defensive pressure affects basketball technical actions but not the time-motion variables

Abstract

BackgroundNovel player tracking technologies can change the understanding of performance determinants in team sports by allowing to accurately measuring the activity demands. The aim of this study was to identify how the defensive pressure affects the time-motion variables and the technical actions in basketball.MethodsTwenty international male players (age: 16.05 ± 2.09 years, weight: 73.13 ± 8.10 kg, height: 183.10 ± 5.88 cm) played two 10 min basketball quarters, where they used a man-to-man 1/4-court defense until the 4th min (F1/4), changed to man-to-man full court (FULL) for 3 min and, from the 7th to the 10th min returned to 1/4-court defense (S1/4). A computerized notational analysis was performed using Simi Scout and positional data were captured with the Ubisense Real Time Location System (mean sampling rate 3.74 ± 0.45 Hz per transmitter/player).ResultsThe time-motion variables presented similar results between defensive conditions, showing a total distance covered around 90 m/min. However, results suggested possible vertical jump impairments in S1/4 periods. There was more distance covered while jogging in the offensive court (38.15 ± 12.17 m/min offensive court vs. 32.94 ± 10.84 m/min defensive court, p < 0.05) and more distance covered while running in the defensive court (16.41 ± 10.27 m/min offensive court vs. 19.56 ± 10.29 m/min defensive court, p < 0.05).ConclusionThese results suggest how to improve task representativeness during specific conditioning or game-based training situations and also to help coaches' strategic decisions during the games.

Model of Defending Tactics For Students Aged 14-16 Years Old

“…Each team member needs to apply team tactics by making decisions during the game. The findings of this study is supported by a study conducted by Sampaio who stated that defending exercises can improve cohesion, communication, responsibility and self confidence [7].…”

Training and Competition Load Monitoring and Analysis of Women's Amateur Basketball by Playing Position: Approach Study

“…The tactical instructions were the same as those performed in matches and fluctuated depending on the opponent (Abdelkrim et al, 2010). It has been stated that time-motion variables do not vary according to different defensive tactics (Sampaio et al, 2016). The tasks of 5 vs. 5 respected the rules of the competition and the scoreboard was used to control time, fouls, free-throws.…”

The effect of repeated sprint ability on physiological and physical profiles of young basketball players. [El efecto de esprines repetidos en los perfiles fisiológicos y físicos de jóvenes jugadores de baloncesto].

“…For players we used cycling instead running, which is their regular exercising activity. Further research can follow up these results by using data collected in game-specific simulated basketball activities (Sampaio, Leser, Baca, Calleja-Gonzalez, Coutinho, Gonçalves, & Leite, 2016) and in formal competitions, using novel player tracking technologies (Scanlan, Fox, Borges, Tucker, & Dalbo, 2016).…”
