What It Involves
A submaximal step-based fitness test - you step up and down a fixed-height box at an increasing pace set by an audio cue, while your heart rate is monitored, estimating your aerobic capacity (VO2max) without needing to push to full exhaustion. It's widely used across offshore, maritime, wind turbine and diving medicals, where working at height or in an emergency evacuation demands a genuine baseline level of fitness, not just the absence of illness.
