Study ID	ST003348
Study Title	An integrated LC-MS analysis of the biometric characteristics of different time cohorts of race walkers - untargeted
Study Summary	To obtain metabolic changes during endurance exercise, we conducted a metabolomics study in which 19 race walkers were recruited to collect blood at four time points: before, during, after, and after rest until day two using both non-targeted and targeted methods. A total of 859 metabolites and 411 lipids were identified by non-targeted methods, and 465 metabolites were quantitatively identified by targeted methods. This extensive data set provides a valuable resource for understanding systemic metabolic changes caused by race walking and helps researchers identify biomarkers of exercise performance.

Sample Preparation:

Sampleprep ID:	SP003476
Sampleprep Summary:	The aliquots were thawed at 4 ° C for 60 minutes and then gently blown with a pipetting gun to allow uniform distribution of the sample. Then, 120μL of serum was transferred to a 2 mL EP tube (Aixgen USA), and 480 μL of methanol was added. The samples were vortexed for 5 min then allowed to stand for 10 min at room temperature and centrifuged at 13000 g at 4 °C (Thermo Scientific, USA) for 10 minutes. The upper extracts were transferred to a 1.5ml tube and lyophilized for 3 hours in a vacuum freeze dryer (Labconco Corporation, USA) and then stored at 4 °C until injection. Prior to analysis, the extracts were redissolved in 500 μl acetonitril-water (1:3,v/v). Quality control (QC) samples were prepared by mixing equal amounts of samples.
