Interinstitutional differences in clinical pediatric exercise laboratory (CPEL) practices may affect patient care and efficacy of multicenter research. Purpose: To describe current practices/procedures in CPELs and explore differences in CPELs employing exercise physiologists to those that do not. Methods: A 40-item survey was distributed to CPELs in North America focusing on (1) staffing; (2) exercise stress testing (EST) volumes, reporting, and interpretation; and (3) EST procedures/protocols. Results: Of the 55 responses, 89% were in the United States, 85% were children’s hospitals with university affiliation, and 58% were cardiology specific. Exercise physiologists were employed in 56% of CPELs, and 78% had master’s degrees or higher. Certifications were required in most CPELs (92% emergency life-support, 27% professional, and 21% clinical). Median volume was 201 to 400 ESTs per year, 80% used treadmill, and 10% used cycle ergometer as primary modalities. Ninety-three percent of CPELs offered metabolic ESTs, 87% offered pulmonary function testing, 20% used institution-specific EST protocols, and 72% offered additional services such as cardiac/pulmonary rehabilitation. CPELS staffing exercise physiologists performed higher volumes of ESTs (P = .004), were more likely to perform metabolic ESTs (P = .028), participated in more research (P < .001), and provided services in addition to ESTs (P = .001). Conclusions: Heterogeneity in CPELs staffing and operation indicates need for standardization.

临床儿科运动实验室 (CPEL) 实践中的机构间差异可能会影响患者护理和多中心研究的有效性。目的：描述 CPEL 中当前的实践/程序，并探讨 CPEL 中雇用运动生理学家与未雇用运动生理学家的差异。方法：向北美的 CPEL 分发了一份包含 40 个项目的调查，重点是 (1) 人员配置；(2) 运动压力测试 (EST) 量、报告和解释；(3) EST 程序/协议。结果：在 55 份回复中，89% 在美国，85% 是大学附属的儿童医院，58% 是心脏病学专科医院。56% 的 CPEL 聘用了运动生理学家，其中 78% 拥有硕士或更高学位。大多数 CPEL 都需要认证（92% 的紧急生命支持、27% 的专业和 21% 的临床）。平均训练量为每年 201 到 400 次 EST，80% 使用跑步机，10% 使用自行车测力计作为主要方式。93% 的 CPEL 提供代谢 EST，87% 提供肺功能测试，20% 使用机构特定的 EST 方案，72% 提供心/肺康复等额外服务。CPELS 配备的运动生理学家进行了更多的 EST（P  = .004），更有可能进行代谢 EST（P  = .028)，参与了更多研究 ( P  < .001)，并提供了 EST 之外的服务 ( P  = .001)。结论： CPEL 人员配备和操作的异质性表明需要标准化。
