运动反应从 149 名儿童和年轻人（平均年龄 14.5 岁）中获得，并按性别和体表面积 (BSA) 划分：BSA < 1 m2 的儿童；BSA < 1 m2 的儿童； BSA 1-1.19 m2 的儿童；患有 BSA .gtoreq 的男性。 1.2平方米；以及患有 BSA .gtoreq 的女性。 1.2平方米。对于 BSA < 1 m2 的儿童以及 BSA .gtoreq 的男性和女性，总做功、平均和最大功率输出更受身体尺寸（身高）的影响，而不是年龄的影响。 1.2平方米。在最大努力时，平均收缩压比运动前仰卧位值增加高达 64%，除了 BSA 1-1.19 m2 的儿童外，所有亚组的平均最大收缩压水平与体型（身高）、功率输出和运动前坐位收缩压呈正相关。在最大努力时，平均舒张压比运动前仰卧位值增加了 24%。 12.1% 的人群（149 人中的 18 人）在运动高峰期 ST 段压低 1-2 毫米。这些变化发生在 8.9% 的男性和 16.9% 的女性中 (P > 0.1)。这些数据揭示了性别和体型在成长受试者运动反应临床解释中的重要性，为客观评估有或无心脏异常的受试者提供参考，并为运动研究期间仔细监测受试者提供指导。 [运动测试正在成为患有心脏疾病的儿童和年轻人诊断评估的一个组成部分]。
Exercise responses were obtained from 149 children and young adults (average age 14.5 yr) and divided by sex and body surface area (BSA): children with BSA < 1 m2; children with BSA 1-1.19 m2; males with BSA .gtoreq. 1.2 m2; and females with BSA .gtoreq. 1.2 m2. Total work, mean and maximal power outputs were more affected by body size (height) than age in children with BSA < 1 m2 and in males and females with BSA .gtoreq. 1.2 m2. Mean systolic pressure increased up to 64% above the preexercise supine value at peak effort, with the level of mean maximal systolic pressure having a positive relationship with body size (height), power output and preexercise sitting systolic pressure in all subgroups except children with BSA 1-1.19 m2. Mean diastolic pressure increased up to 24% above the preexercise supine value at peak effort. ST-segment depression of 1-2 mm was recorded in 12.1% (18 of 149) of the population at peak exercise. These changes occurred in 8.9% of all males and in 16.9% of all females (P > 0.1). The data reveal the importance of sex and body size in the clinical interpretation of exercise responses in growing subjects, provide a reference for objective evaluation of subjects with or without cardiac abnormalities and provide a guide for careful monitoring of subjects during an exercise study.
