Overview

Double product break-point detectable at low workloads; hypothesis-generating for noninvasive cardiac workload assessment, needs clinical validation.

Structured PICO

P
Population
11 young male adults
I
Intervention
Graded bicycling exercise increasing 20 watts every 2 min from 0 watts until heart rate reached 170 beats.min(-1)
O
Outcome
Change in double product with increases in the intensity of bicycle exercisesurrogate

The double product exhibits a clear break-point during stepwise incremental exercise even at relatively low workloads.
