Abstract

Recent literature has shown that the provision of feedback can enhance vertical jump performance acutely, as well as chronically when implemented during phases of training. The aim of our study was to investigate the influence of two types of visual feedback on performance and variability of countermovement jump-derived force-time characteristics in a cohort of male and female National Collegiate Athletic Association Division 1 basketball players. Specifically, individual visual feedback (IVF) was compared to a form of social comparison feedback (SCF), and authors hypothesized there to be performance increases and more stable measures in the SCF condition. In line with this hypothesis, findings suggested significantly enhanced performance in the SCF condition for seven out of eight force-time metrics (e.g. jump height and reactive strength index modified). However, given the small between-condition effect sizes, differences between conditions may lack practical significance. Furthermore, findings suggested less between-jump variability in the SCF condition, compared to the IVF condition, making for a more stable assessment. This in particular makes for more reliable measures, for which when studied over time, more subtle changes in performance may be observed. In summary, our findings highlight acutely enhanced vertical jump performance, and more stable measures, when athletes are exposed to an SCF condition, compared to a normal IVF condition. Practitioners are encouraged to consider these findings when planning vertical jump assessments and are discouraged from implementing different types of feedback at random, especially when measuring performance over time.
大学篮球运动员纵跳测试的注意事项:即时个人与社会比较反馈和团队排行榜参与的影响
最近的文献表明,在训练阶段提供反馈可以快速提高纵跳成绩,也可以长期提高纵跳成绩。我们的研究旨在调查两种类型的视觉反馈对全国大学生体育协会一级篮球联赛男女运动员逆向运动起跳力-时间特征的表现和变异性的影响。具体来说,将个人视觉反馈(IVF)与一种社会比较反馈(SCF)进行了比较,作者假设在 SCF 条件下,成绩会提高,测量结果会更稳定。与这一假设相符的是,研究结果表明,在 SCF 条件下,八项力量-时间指标中的七项(如跳跃高度和修正的反应力量指数)的成绩都有显著提高。然而,由于条件间效应大小较小,条件间的差异可能缺乏实际意义。此外,研究结果表明,与 IVF 条件相比,SCF 条件下的跳跃间变异性较小,因此评估结果更加稳定。这尤其使得测量结果更加可靠,在对其进行长期研究时,可能会观察到更微妙的成绩变化。总之,我们的研究结果表明,与正常的 IVF 条件相比,当运动员处于 SCF 条件下时,纵跳成绩会迅速提高,测量结果也会更加稳定。我们鼓励运动员在计划立定跳远评估时考虑这些研究结果,并且不鼓励运动员随意采用不同类型的反馈,尤其是在长期测量成绩时。

期刊介绍: The International Journal of Sports Science & Coaching is a peer-reviewed, international, academic/professional journal, which aims to bridge the gap between coaching and sports science. The journal will integrate theory and practice in sports science, promote critical reflection of coaching practice, and evaluate commonly accepted beliefs about coaching effectiveness and performance enhancement. Open learning systems will be promoted in which: (a) sports science is made accessible to coaches, translating knowledge into working practice; and (b) the challenges faced by coaches are communicated to sports scientists. The vision of the journal is to support the development of a community in which: (i) sports scientists and coaches respect and learn from each other as they assist athletes to acquire skills by training safely and effectively, thereby enhancing their performance, maximizing their enjoyment of the sporting experience and facilitating character development; and (ii) scientific research is embraced in the quest to uncover, understand and develop the processes involved in sports coaching and elite performance.
