Can the interpretation of lactate performance curves be improved by means of easily accessible parameters? Different cycle ergometer tests after glycogen loading and glycogen depletion were performed by 28 subjects (3.9 W/kg to 6 W/kg). Measured quantities were lactate, heart rate (HR), and breath rate (BR). In all experiments glycogen depletion led to increase in HR and BR and a decrease in lactate. The increases in BR were more distinct with high intensities. Low lactate with simultaneously enhanced HR and BR may be indicative of a beginning glycogen depletion. Low lactate with simultaneously decreased HR and BR is indicative of an improvement in the performance. High lactate and low HR and BR at the same load show good regeneration. Verf.-Referat
