Idiopathic scoliosis affects the locomotor system; however, it can considerably impair the function of cardiovascular and respiratory systems. The aim of the study was to assess parameters indicating the physical capacity of adolescent girls with mild or moderate idiopathic scoliosis.
The study included 97 girls, aged 10-18 years: 70 girls, aged 13.84 ± 2.2 years, with idiopathic thoracic scoliosis (Cobb angle 10°-40°) formed the study group and 27 healthy girls, aged 13.2 ± 1.9 years, formed the control group. The girls underwent the Physical Work Capacity 170 (PWC170) test on a cycle ergometer based on two 5-min submaximal physical effort events. The maximum oxygen intake was calculated and expressed in l/min and ml/kg/min. The impact of the curvature angle value, of the number of vertebrae within the curve and of the number of the curves on the physical capacity parameters was analyzed.
The maximal oxygen intake (l/min) and PWC170 (W; W/kg) values were considerably lower in girls with scoliosis of 25°-40° than in the control group. No significant differences were observed between girls with mild scoliosis (10°-24°) and the control group. Statistical analysis did not show any significant impact of the number of vertebrae affected by scoliosis and the number of curvatures on VO(2)max (l/min; ml/kg/min) and the PWC170 (W) indicator. In the group of girls with scoliosis involving more than nine vertebrae, the PWC170 (W/kg) indicator was significantly lower than in the control group. A similar correlation was observed between girls with double-curved scoliosis and the control group (p < 0.05).
The maximum oxygen intake and the output during the PWC170 test is lower in girls with moderate scoliosis than in the control group. The value of maximum oxygen intake and output obtained during the PWC170 test in girls with mild scoliosis does not differ significantly from the values obtained in the control group. The number of vertebrae involved in scoliotic deformation and the number of curvatures cause significant decrease in only the relative value of the output obtained during an exercise test.
特发性脊柱侧凸影响运动系统；然而，它会严重损害心血管和呼吸系统的功能。本研究的目的是评估轻度或中度特发性脊柱侧凸的青春期女孩的身体能力参数。
该研究包括 97 名 10-18 岁的女孩：70 名患有特发性胸段脊柱侧凸（Cobb 角 10°-40°）的女孩，年龄为 13.84±2.2 岁，为研究组；27 名健康女孩，年龄为 13.2±1.9 岁，为对照组。女孩们在自行车测功计上进行了基于两次 5 分钟亚最大体力活动事件的体力工作能力 170（PWC170）测试。计算最大摄氧量并以 l/min 和 ml/kg/min 表示。分析了曲率角值、曲线内的椎体数量和曲线数量对身体能力参数的影响。
25°-40°的脊柱侧凸女孩的最大摄氧量（l/min）和 PWC170（W；W/kg）值明显低于对照组。轻度脊柱侧凸（10°-24°）女孩与对照组之间无显著差异。统计分析未显示脊柱侧凸受累椎体数量和曲线数量对 VO2max（l/min；ml/kg/min）和 PWC170（W）指标有任何显著影响。在涉及超过九个椎体的脊柱侧凸女孩中，PWC170（W/kg）指标明显低于对照组。双曲脊柱侧凸女孩与对照组之间也观察到类似的相关性（p<0.05）。
中度脊柱侧凸女孩的最大摄氧量和 PWC170 试验输出低于对照组。轻度脊柱侧凸女孩在 PWC170 试验中获得的最大摄氧量和输出值与对照组相比无显著差异。脊柱侧凸变形涉及的椎体数量和曲线数量仅导致运动试验中获得的输出的相对值显著降低。
