Basketball has a high demand on a player's neuromuscular system due to a high volume of explosive high-intensity actions. This study aimed to examine the seasonal variations on game demands and players' neuromuscular performance during the Non-Conference (NON-CONF) and Conference (CONF) seasons in NCAA Division I Men's Basketball. Seven NCAA Division I Basketball players' (20 ± 1.2 years, 1.95 ± 0.1 m, and 94 ± 15 kg) match activity profiles were tracked in 17 home games (7 NON-CONF; 10 CONF); furthermore, players performed a repeat hop test on a force platform the day before competition to assess neuromuscular performance. A -test for paired samples was used to analyze the differences between NON-CONF and CONF. Results indicated no significant differences in Total Distance, Peak Speed, Acceleration, and Deceleration loads when comparing NON-CONF and CONF match-play. Regarding neuromuscular performance, Jump Height ( = 0.03; ES = 0.43) was negatively affected during CONF. Moreover, a trend toward a decline in Peak Force ( = 0.06; ES = 0.38) was found in CONF. Conversely, no differences were obtained regarding Reactive Strength Index and Contact Time. In conclusion, match-play demands remained constant across the season whilst neuromuscular outputs were inhibited during the CONF season.
由于大量爆发性的高强度动作，篮球运动对运动员的神经肌肉系统要求很高。本研究旨在调查美国大学体育协会（NCAA）一级男子篮球非联盟赛季（NON-CONF）和联盟赛季（CONF）期间比赛需求和运动员神经肌肉表现的季节性变化。在17场主场比赛（7场非联盟赛；10场联盟赛）中跟踪了7名NCAA一级篮球运动员（20±1.2岁，身高1.95±0.1米，体重94±15千克）的比赛活动概况；此外，运动员在比赛前一天在测力平台上进行重复单脚跳测试，以评估神经肌肉表现。使用配对样本t检验分析非联盟赛和联盟赛之间的差异。结果表明，比较非联盟赛和联盟赛的比赛时，总距离、峰值速度、加速度和减速度负荷没有显著差异。关于神经肌肉表现，联盟赛季期间垂直跳高度（p = 0.03；效应量= 0.43）受到负面影响。此外，在联盟赛季中发现峰值力量有下降趋势（p = 0.06；效应量= 0.38）。相反，反应力量指数和接触时间没有差异。总之，整个赛季的比赛需求保持不变，而神经肌肉输出在联盟赛季受到抑制。
