研究设计：实验和横断面研究。目的：评价运动对轮椅篮球运动员脊髓损伤(SCI)患者心率(HR)、摄氧量(VO2)、肺通气量(PV)、氧脉搏(OP)、血糖和血脂的即刻影响。结果：在相同强度的运动训练中，SCI组运动员的VO2、PV、OP、VO2、PV和OP均显著低于C组。而SCI组的HR、PV和OP升高的速度与C组相似(P=0.017)，而C组无此升高。在VT1以上15%的运动时段，SCI组仅在30min后血糖(P=0.040)和低密度脂蛋白(P=0.012)升高。结论：SCI组HR、PV和OP在运动后30min升高，但与C组无显著差异。
STUDY DESIGN: Experimental and cross-sectional study.OBJECTIVE: To assess the immediate effect of exercise on heart rate (HR), oxygen uptake (VO2), pulmonary ventilation (PV), oxygen pulse (OP), glucose and lipids of wheelchair basketball players with spinal cord injury (SCI).SETTING: Center of Studies in Psychobiology and Exercise-Sao Paulo, Brazil.METHODS: In all, nine wheelchair basketball players with SCI and nine able-bodied controls (C) performed three exercise sessions at different intensities: ventilatory threshold 1 (VT1), 15% below VT1 and 15% above VT1 with a duration of ~24-34min. HR, VO2, PV, OP, glucose and lipids were analyzed.RESULTS: VO2, PV and OP were significantly lower in the players with SCI compared to C during the same intensity exercise sessions. However, the individuals with SCIs demonstrated increases in HR, PV and OP at similar rates to C. Triglycerides of the SCI group were elevated 30min after the exercise session at VT1 compared to values before the exercise session (P=0.017); this elevation was not observed in group C. For the exercise sessions 15% above VT1, only glucose (P=0.040) and low-density lipoprotein (P=0.012) 30min after the exercise were elevated in the SCI group compared to group C.CONCLUSION: We conclude that the SCI group demonstrated increases in HR, PV and OP but not VO2 with increased intensity of exercise at similar rates as in group C.
