Key result
Maximum treadmill exercise yields a ~0.10 higher post-exercise ABI versus bicycle exercise in athletes.
Why the study?
The normal ankle and arm pressure and ankle-brachial index response to incremental maximum bicycle and treadmill exercise in athletes had not been compared.
Does incremental maximum bicycle exercise compared to treadmill exercise result in different ankle-brachial index responses in athletes?
Cross-Sectional (n=13)
Does incremental maximum bicycle exercise compared to treadmill exercise result in different ankle-brachial index responses in athletes?
The limit cut-off point for diagnosing lower extremity arterial disease in athletes defined for maximum bicycle tests may not apply to maximum incremental treadmill tests due to significant differences in post-exercise ABI.

May inform modality-specific ABI reference values during maximal exercise; leaves open validation in clinical PAD populations.
Previous works have focused on the normal ankle and arm pressure response to maximum bicycle exercise or moderate walking tests. The aim of the present work was to compare the normal ankle and arm pressure and ankle-brachial index response to incremental maximum bicycle and treadmill exercise in 13 athletes (11 men, two women, 24 +/- 11 years) No difference was found at rest on both ankle pressure 139 +/- 21 vs. 163 +/- 22 mmHg and ankle-brachial index 1.18 +/- 0.09 vs. 1.17 +/- 0.10 between bicycle and treadmill tests respectively (mean +/- SD). One minute after maximum exercise, no difference in arm pressure was found between bicycle (182 +/- 16 mmHg) and treadmill tests (190 +/- 17 mmHg), whereas ankle pressure was 139 +/- 21 vs. 163 +/- 22 mmHg respectively (P < 0.05). As a result, a significant difference was found in the ankle-brachial index 0.76 +/- 0.10 vs. 0.86 +/- 0.10 (P < 0.05) between bicycle and treadmill ergometers during the first minute of the recovery period. Although performed at comparable workloads, a significant difference was noted between running and cycling tests. Thereby, the limit cut-off point for the diagnosis of lower extremity arterial disease in athletes defined for maximum bicycle tests may not apply to maximum incremental treadmill tests.

Abraham et al. (1998) conducted a cross-sectional in Healthy athletes (n=13). Incremental maximum treadmill exercise vs. Incremental maximum bicycle exercise was evaluated on Ankle-brachial index during the first minute of the recovery period (p=<0.05). Incremental maximum treadmill exercise resulted in a significantly higher ankle-brachial index one minute post-exercise compared to bicycle exercise in athletes (0.86 vs 0.76; P<0.05).
