The effect of different work rate increasing rates on cardiopulmonary exercise testing in arm ergometer.

ABSTRACT:

Background

Cycle ergometer is commonly used for cardiopulmonary exercise testing (CPET), which is the objective and quantitative golden standard for functional evaluation and training, while arm CPET is less commonly used to clinically assess a patient's overall functioning. To determine optimal CPET protocols, we studied the effect of different work rate increasing rates of arm ergometer on CPET key variables.

Methods

We recruited fourteen non-symptomatic participants without any clinical diagnosis, and first performed maximal leg CPET for functional evaluation, followed by four maximal arm ergometer CPETs using different work rate increasing rates (5, 20, 35, and 50 W/min) in random order on various days in one week (7 days). The key variables are oxygen uptake ( V˙CO2 ),
