The Canadian Home Fitness Test (CHFT) and the Bruce treadmill test were performed by 230 men aged 45 to 69 years. Because of inaccuracies in the counting of heart rates, less was known about the fitness of the men after testing than before. In addition, inaccuracies in the test record and design were uncovered. A more accurate estimate of fitness could be obtained when the subjects' own rating of exertional intensity was substituted for heart rate counting. The CHFT is a marketing tool of Health and Welfare Canada that may be useful in selling fitness, but as a measure of fitness in Canadian homes it is likely to be misleading.
230名年龄在45至69岁之间的男性参与了加拿大家庭健身测试（CHFT）和布鲁斯跑步机测试。由于心率计数不准确，测试后这些男性的健康状况比测试前了解得更少。此外，还发现了测试记录和设计中的不准确之处。当用受试者自己对运动强度的评级代替心率计数时，可以获得更准确的健康状况估计。CHFT是加拿大健康与福利部的一种营销工具，可能有助于推广健身，但作为加拿大家庭中健康状况的衡量标准，它可能会产生误导。
