: The aim was to analyze the differences between wheelchair basketball players with Spinal Cord Injury (SCI) and without Spinal Cord injury (Non-SCI) in psycho-physiological response and neuromuscular fatigue in a series of small-sided games (SSG). : Thirteen high-level wheelchair basketball male players (age 28.8 ± 9.2 years, body mass 75.9 ± 11.3 kg) participated in four versus four SSG once a week for five consecutive weeks. Absolute and relative heart rate (HR) during SSG and muscular and respiratory perceived exertion (RPEmus and RPEres), tympanic temperature, and acceleration capacity were recorded at the end of each SSG. : No significant differences were observed between SCI and non-SCI players in relative HR variables in SSG series. However, the SCI group had a lower absolute HR (mean HR and peak HR) ( < .05 or < .01, ES = 0.73-1.39) and higher perceived muscular load (RPEmusTL) ( < .01, ES = 0.75-0.82) during SSG. Regarding the evolution of the physiological response, no differences were observed between the four bouts in the SCI group. However, the Non-SCI group showed an increase in the absolute and relative variables of HR and RPEres and RPEmus ( < .05 or < .01, ES = 0.45-1.06). On the contrary, only the SCI group showed a loss of acceleration capacity between the four series ( < .05, ES = 0.28-0.35). : The results of this study show that there are differences between SCI and non-SCI wheelchair basketball players in their physiological response and acceleration capacity during SSG tasks.
目的是分析脊髓损伤（SCI）和非脊髓损伤（非SCI）的轮椅篮球运动员在一系列小型比赛（SSG）中的心理生理反应和神经肌肉疲劳的差异。13名高水平轮椅篮球男性运动员（年龄28.8±9.2岁，体重75.9±11.3千克）连续五周每周参加一次四对四的SSG。在每次SSG结束时记录SSG期间的绝对和相对心率（HR）以及肌肉和呼吸自觉用力程度（RPEmus和RPEres）、鼓膜温度和加速能力。在SSG系列中，SCI组和非SCI组在相对HR变量上未观察到显著差异。然而，SCI组在SSG期间的绝对心率（平均心率和峰值心率）较低（P<0.05或P<0.01，效应量ES=0.73-1.39），且自觉肌肉负荷（RPEmusTL）较高（P<0.01，效应量ES=0.75-0.82）。关于生理反应的演变，SCI组在四场比赛之间未观察到差异。然而，非SCI组的HR、RPEres和RPEmus的绝对和相对变量有所增加（P<0.05或P<0.01，效应量ES=0.45-1.06）。相反，只有SCI组在四个系列之间表现出加速能力下降（P<0.05，效应量ES=0.28-0.35）。本研究结果表明，SCI和非SCI轮椅篮球运动员在SSG任务期间的生理反应和加速能力存在差异。
