Abstract

In fast-paced team sports, anticipation is one important element in defense strategies. The primary objective of this study was to examine the recommendation for action and use of defensive gaze strategies by defensive players in basketball. Four national-level expert-basketball coaches were interviewed and a field study with mobile eye-tracking devices was conducted on 16 expert and 16 novice players defending in a one-on-one situation. Differences in relative fixation times between experts and novices were elaborated for the predetermined gaze zones-head, ball, torso, and feet-as given by the expert coaches. This was done for three phases of the movement sequence: receiving, dribbling, and shooting. The results of the interviews with expert coaches indicated that the existing coaching doctrine instructs players to look at the torso of an opponent to avoid being vulnerable to fakes. Surprisingly, our findings with the players showed a discrepancy in the evaluated gaze behavior of the experts and novices. For the receiving and dribbling phase, experts mainly fixated their gaze on the head while novices focused on the ball. For the final shooting phase, both the groups mainly fixated their gaze on the ball. Fixating the gaze on the ball or head makes the player potentially vulnerable to deceptive movements, as video-based research has shown. Expert coaches also indicated that peripheral vision is of importance to defenders, contradicting the existing assumption in the literature that focusing on the task-relevant areas is key for anticipation performance.

篮球一对一防守者的视觉-凝视行为。

在快节奏的团队运动中，预判是防守策略中的一个重要元素。本研究的主要目的是研究防守球员在篮球比赛中防守凝视策略的建议和使用。对4名国家级篮球专家教练进行访谈，并采用移动眼动仪对16名专家级球员和16名新手球员进行一对一防守的实地研究。在专家教练给出的预定注视区域——头部、球、躯干和脚上，专家和新手在相对注视时间上的差异得到了详细阐述。这是完成了三个阶段的运动序列:接球，运球和投篮。对专家教练的采访结果表明，现有的教练原则指导球员看对手的躯干，以避免容易被假。令人惊讶的是，我们对玩家的研究结果显示，专家和新手在评估的凝视行为上存在差异。在接球和运球阶段，专家的注意力主要集中在头部，而新手的注意力则集中在球上。在最后的投篮阶段，两组人的目光都集中在球上。基于视频的研究表明，将目光固定在球或头部上可能会使球员容易受到欺骗性动作的影响。专家教练还指出，外围视觉对后卫来说很重要，这与现有文献中关于专注于任务相关区域是预期表现关键的假设相矛盾。

期刊介绍： The Journal of Sport & Exercise Psychology (JSEP) is a peer-reviewed publication designed to stimulate and communicate research theory in all areas of sport and exercise psychology. JSEP emphasizes original research reports that advance our understanding of human behavior as it relates to sport and exercise. Comprehensive reviews employing both qualitative and quantitative methods are also encouraged, as well as brief reports of soundly designed research studies that are of special interest or importance. Areas of interest include research in social, clinical, developmental, and experimental psychology, as well as psychobiology and personality. Moreover, the terms sport and exercise may pertain to either the independent or dependent variables. Generally speaking, work on motor control processes, studies of sport as a social institution, or broader social issues are beyond the scope of JSEP. A wide variety of methods are acceptable for studying sport and exercise psychology topics.
