摘要

Purpose: To investigate the recovery rate of metabolic indicators after high-intensity exhaustive exercise.
Method: Subjects performed exercise to exhaustion on a motorized treadmill following the Ellestard protocol to determine the maximal aerobic power (VO2max). The speeds for 80% exhausted running was calculated for each subjects as the suggestion of CSM: VO2=(0.2×speed)+(0.9×speed×grade)+3.5. Five milliliters of blood samples were intravenously collected from the subjects before and after the exhaustive exercise. The sampling times were 0, 0.5, 1, 2, 24, 48 hours after the exhaustive exercise, respectively. Analysis: Concentrations of blood urea nitrogen (BUN), creatine kinase (CK), and lactate dehydrogenase (LDH), respectively, were determined as the biomarkers of human metabolism. The data were analyzed by the one-way analysis of variance (ANOVA).
Results: It was shown that the concentrations of metabolic indicators BUN, CK, and LDH all increased significantly after the exhaustive exercise (P＞.05). Concentrations of both BUN and LDH rose to a maximum 2 hours after the exercise and subsequently gradually recovered till 24 hours after the exercise. Concentration of CK increased with the time, to a maximum at about 24 hours, after the exercise, thereafter decreased with the time till 48 hours after the exercise.
Conclusion: High-intensity exhaustive exercise affected the concentrations of metabolic indicators BUN, CK, and LDH, especially for CK till 24 hours after the exercise. It was suggested that the exhaustive exercise should be performed accompanying with a time period, i.e., 24 hours, enough for the recovery of metabolic revitalization.
