3 Fig 2 Study design and subject flow through sessions A and B (both divided into 2 parts separated by 60-minute rest with nutrition). Abbreviations: HRR, heart rate reserve; PLE, perceived level of exertion.

4 Fig 3 Performance on the ARAT improved more (2.5 points) after treadmill exercise than control condition (.16 points; * indicates P<.05).

5 Fig 4 Change in ARAT score after BWSTT is associated with maximum treadmill speed. Linear regression line indicates R2 equal to 0.2 (P=.04). Polynomial U-shaped curve shows a more robust effect for the very slowest walkers.
