Abstract

Objective: The purpose of this study was to examine fasted blood glucose as a predictor of lactate levels measured by Method CRA. Method: Participants and data for the present study were collected by employees of an orthopedic rehabilitation center in Bloomington, Illinois. Participants recruited for the study followed the Method CRA upright cycle testing protocol. Fasted blood glucose, resting lactate, and heart rate measurements at Prime (2 mmol/L) and Anaerobic (4 mmol/L) were recorded. Blood was sampled every three minutes during exercise testing. The total sample size of 35 was examined as well as two subgroups, BMI > 30 group and the SD group. Data was analyzed using regression models. Results: A total of 35 participants were included. Participant’s average age was 52.8 years, average fasted blood glucose was 120.4mg/dL, average resting lactate was 1.19mmol/L, average Prime of 107.17bpm, and average Anaerobic of 128.2bpm. The study found that blood glucose was a significant predictor of resting lactate in the BMI >30 group (n = 26, p = 0.03) and a significant predictor of Prime HR in the SD group (n = 3, p = 0.02). Conclusion: Blood glucose was found to significantly predict resting lactate in a subgroup with individuals having a BMI > 30. This indicates that in obese individuals, elevated blood glucose could be indicative of an elevated resting lactate. Blood glucose was also found to be a significant predictor of Prime HR in individuals who met the criteria for significant deconditioning.
