摘要

本研究旨在比较与不同技术水平的篮球对手比赛时的体能需求。18 名男子大学生篮球运动员佩戴加速度计,在与职业队(Pro)、同一竞技水平的球队(Collegiate)以及练习赛(Scrimmage)中由队内成员组成的球队进行比赛时,测量相对累积加速度负荷(AAL)、估计等效距离以及冲刺、跳跃和用力项目的频率。内部反应采用感知用力的相对等级(sRPE)进行计算。通过重复测量方差分析、Bonferroni 事后检验和标准化的科恩效应大小,来比较与不同水平对手比赛时的体能需求和内部反应。结果显示,在与职业队的比赛中,AAL(任意单位)、冲刺项目(每分钟例数)和用力项目(每分钟例数)显著高于与大学生队和散打队的比赛(P < .05)。随着对手竞技水平的提高,参与者的相对外部负荷也随之增加。相反,使用 sRPE 测量的内部反应在与职业队比赛后低于与大学生队的比赛。内部和外部负荷可能会因环境因素而有所不同。

A comparison of the physical demands generated by playing different opponents in basketball friendly matches.

This study aimed to compare the physical demands of playing opponents of different skill levels in basketball. Eighteen men's college basketball players wore accelerometers to measure the relative accumulated acceleration load (AAL), estimated equivalent distance, and frequencies of sprint, jump, and exertion events during games against professional teams (Pro), teams at the same competition level (Collegiate), and teams comprising intra-team members in practice games (Scrimmage). Internal responses were calculated using the relative rating of perceived exertion (sRPE). A repeated measures analysis of variance, Bonferroni post-hoc tests, and standardized Cohen's effect sizes were calculated to compare the physical demands and internal responses across matches played against different levels of opponents. The results showed that in the game against the Pro, AAL (arbitrary units), sprint events (cases per min), and exertion events (cases per min) were significantly (p < .05) higher than those in games against the Collegiate and Scrimmage teams. As the competitive level of the opponents increased, the relative external load of the participants also increased. Conversely, internal responses measured using sRPE were lower after games against the Pro than those against the Collegiate. Internal and external loads may vary from each other depending on contextual factors.

期刊介绍: Biology of Sport is the official journal of the Institute of Sport in Warsaw, Poland, published since 1984. Biology of Sport is an international scientific peer-reviewed journal, published quarterly in both paper and electronic format. The journal publishes articles concerning basic and applied sciences in sport: sports and exercise physiology, sports immunology and medicine, sports genetics, training and testing, pharmacology, as well as in other biological aspects related to sport. Priority is given to inter-disciplinary papers.
