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.
