Little is known about motor competence and the longitudinal development of motor performance among youth with cystic fibrosis (CF). In this study, we assessed aspects of motor performance in different age groups of young patients with CF and compared them with a healthy reference group of same aged children. We also examined the development of motor performance among different age groups of these children with CF, using The Deutscher Motorik Test (DMT) to assess attributes of health-related and motor performance-related fitness. We used an incremental ergometer cycle test to determine maximal exercise capacity (expressed as peak workload). We evaluated and recorded habitual physical activity (PA) as measured by the number of steps per day and the time spent in different PA intensities (expressed in metabolic equivalents). In total, 31 children and adolescents with CF agreed to participate (13 girls,18 boys) aged 6-17 years ( = 11.3, =3.3 years); they had a mean one second forced expiratory volume (expressed as a percentage of predicted value [% pred]) of 87.2% ( 22.3%). We found their values of health-related and motor performance-related fitness to be significantly lower ( < 0.05) than those of their healthy peer participants. In contrast to the reference group, participants with CF up to 14 years of age showed a linear improvement in these values and in their PA, followed by a plateau or even a nonsignificant decrease after age 14. These findings have important implications for the development and prescription of exercise programs for children with CF. Besides aerobic and strength exercises, we recommend that neuromuscular training be integrated into exercise programs to improve the coordinative abilities of youth with CF. More attention should be paid to vulnerable older adolescents to ensure their long-term motivation to maintain exercise participation.
关于囊性纤维化 (CF) 青少年的运动能力和运动表现的纵向发展，人们知之甚少。在这项研究中，我们评估了不同年龄段 CF 年轻患者的运动表现，并将其与同年龄段健康对照组进行了比较。我们还使用德文运动测试 (DMT) 检查了这些 CF 儿童不同年龄段运动表现的发展情况，以评估与健康相关和运动表现相关的体能属性。我们使用递增式测力计自行车测试来确定最大运动能力（表示为峰值工作量）。我们评估并记录了日常体力活动 (PA)，通过每天的步数和不同 PA 强度（以代谢当量表示）的时间来衡量。共有 31 名患有 CF 的儿童和青少年同意参与（13 名女孩，18 名男孩），年龄为 6-17 岁（均值为 11.3 岁，标准差为 3.3 岁）；他们的一秒钟用力呼气量（表示为预测值的百分比 [% pred]）的平均值为 87.2%（22.3%）。我们发现他们的健康相关和运动表现相关的体能值明显低于（<0.05）健康同龄参与者。与对照组相比，年龄在 14 岁以下的 CF 参与者在这些值和 PA 方面表现出线性提高，然后在 14 岁后出现平台期甚至非显著下降。这些发现对 CF 儿童的运动方案的制定和处方具有重要意义。除了有氧运动和力量训练外，我们还建议将神经肌肉训练纳入运动方案中，以提高 CF 青少年的协调能力。应更加关注易受影响的大龄青少年，以确保他们长期保持锻炼参与的积极性。
