Figure 1. Structure/duration of work cycles. Prior to each work cycle beginning, firefighters sat in the chamber for 3 minutes of data acquisition set up and 2 minutes of resting data collection.

Figure 2. Multiple trials allowed examination of (a) SCBA size and design (solid line), (b) duration of simulated firefighting activity (dashed line) and (c) the interaction of SCBA and work cycle structure/duration (double line).
