This study aimed to investigate the acute effects of two different resistance circuit training protocols on basketball players' physical and technical performance and rating of perceived exertion (RPE). In a repeated-measures, crossover experimental design, 9 semiprofessional basketball players performed a Power Circuit Training (PCT; 45% 1RM) and a High-Resistance Circuit Training (HRC; 6RM), on consecutive weeks. Vertical and horizontal jump performance, 3-points shooting accuracy, repeated-sprint ability (RSA), agility, and upper body power output were measured before and after training. The RPE was assessed 20 minutes after resistance training. One-way repeated-measures analysis of variance showed performance decrements in vertical jump height and peak power, horizontal jump distance, 3-points percentage, bench-press power output, RSA total and ideal time, and agility T-Test at total time following HRC, but not PCT (p ≤ 0.05). The RPE was higher in HRC compared with PCT. The results of this study indicated that HRC was perceived as being harder and produced higher fatigue levels, which in turn lowered acute performance. However, low-to-moderate intensity loads did not negatively affect performance. Thus, completing a PCT session may be the most appropriate option before a practice or game as it avoids acute-resistance-training-induced performance decrements. However, if the objective of the basketball session is to develop or perfect technical skills during fatiguing conditions, HRC may be the more suitable option.
本研究旨在探讨两种不同的循环抗阻训练方案对篮球运动员身体和技术表现以及主观用力程度（RPE）的急性影响。在重复测量交叉实验设计中，9名半职业篮球运动员连续两周分别进行了力量循环训练（PCT；45%1RM）和高阻力循环训练（HRC；6RM）。在训练前后测量了垂直和水平跳跃成绩、三分球投篮准确性、反复冲刺能力（RSA）、敏捷性以及上身功率输出。在抗阻训练后20分钟评估主观用力程度。单因素重复测量方差分析表明，进行HRC训练后，垂直跳跃高度和峰值功率、水平跳跃距离、三分球命中率、卧推功率输出、RSA总和及理想时间以及敏捷性T检验总用时均出现成绩下降，但PCT训练后未出现（p≤0.05）。与PCT相比，HRC训练后的主观用力程度更高。本研究结果表明HRC被认为难度更大且产生的疲劳程度更高，进而降低了急性表现。然而，低至中等强度负荷并未对表现产生负面影响。因此，在训练或比赛前进行PCT训练可能是最合适的选择，因为它可避免急性抗阻训练导致的表现下降。然而，如果篮球训练的目标是在疲劳状态下发展或完善技术技能，HRC可能是更合适的选择。
