Arm‐crank ergometry may be useful in patients unable to pedal, for instance due to peripheral arterial disease. Twenty participants with small abdominal aortic aneurysm undertook two serial arm‐crank tests and then a pedal test, four of whom had indeterminate anaerobic thresholds, precluding analysis. The mean (SD) peak arm and leg oxygen consumptions in 16 participants were 13.71 (2.62) ml.kg−1.min‐1 and 16.82 (4.44) ml.kg−1.min‐1, with mean (SD) individual differences of 3.11 (2.48) ml.kg−1.min‐1, p = 0.0001. The respective values at the anaerobic thresholds were 7.83 (1.58) ml O2.kg−1.min‐1 and 10.09 (3.15) ml O2.kg−1.min‐1, with mean (SD) individual differences of 2.26 (2.34) ml O2.kg−1.min‐1, p = 0.0001. The correlation coefficients (95%CI) for peak oxygen consumption and anaerobic threshold were 0.88 (0.62–1.0) and 0.70 (0.32–1.0). There were no significant differences in serial arm‐crank tests, with intracluster correlations (95%CI) of 0.87 (0.86–0.88) and 0.65 (0.61–0.69) for peak oxygen consumption and anaerobic threshold, respectively.
