Higher step height increases blood lactate concentrations.
High blood lactate levels are connected to high-intensity workout. They reflect the kinds of motor units recruited (i.e., slow-twitch versus fast-twitch) and blood lactate clearance capacity.
One study discovered that performing a one-minute step test on a 40-centimetre high step leaded to greater blood lactate concentration than using a 20-centimetre step. The higher step demanded greater power and the recruitment of more powerful motor units, which leaded to greater blood lactate concentrations.
