Figure 3
Represents muscle lactate efflux measured during rest and during the 3rd to fourth minute of contraction (this is when a venous blood sample was obtained) and during the first 2 minutes of recovery. Peak lactate efflux muscle was similar during the first 3 periods of muscle contraction. Following 60 min recovery lactate efflux had returned to baseline. The black bars at the top of the graph represent the period of muscle stimulation.
