Abstract
- Background Exercise testing in children is widely recommended for a number of clinical and prescriptive reasons. Many institutions continue to use the Bruce protocol for treadmill testing; however, with its incremental changes in speed and grade, it has challenges for practical application in children. We have developed a novel institutional protocol (British Columbia Children’s Hospital (BCCH)), which may have better utility in paediatric populations. Aim To determine if our institutional protocol yields similar peak responses in minute ventilation (VE), oxygen consumption (VO 2 ), carbon dioxide production (VCO 2 ), respiratory exchange ratio (RER), metabolic equivalents (METS) and heart rate (HR) when compared with the traditional Bruce protocol. Methods On two different occasions, 70 children (boys=33; girls=37) aged 10–18 years completed an exercise test on a treadmill using each of the protocols. During each test, metabolic gas exchange parameters were measured. HR was monitored continuously during exercise using an HR monitor. Results Physiological variables were similar between the two protocols (median (IQR); r s ): VE (L/min) (BCCH=96.7 (72.0–110.2); Bruce=99.2 (75.6–120.0); r s =0.95), peak VO 2 (mL/min) (BCCH=2897 (2342–3807); Bruce=2901 (2427–3654); r s =0.94) and METS (BCCH=16.2 (14.8–17.7); Bruce=16.4 (14.7–17.9); r s =0.89). RERs were similar (BCCH=1.00 (0.96–1.02); Bruce=1.03 (0.99–1.07); r s =0.48). Total exercise time (in seconds) was longer for the BCCH protocol: BCCH=915 (829–1005); Bruce=810 (750-919); r s =0.67. Conclusion The BCCH protocol produces similar peak exercise responses to the Bruce protocol and provides an alternative for clinical exercise testing in children.
