Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

20 trained sprinter were divided into caffeine Gum trial (CAF) and Placebo trial (PL) with a randomized, double-blind study design. The participants chewing either caffeine Gum (CAF trial, containing 3 mg/kg of caffeine) or Placebo Gum (PL) for 10 minutes. The outcomes are Running-Based Anaerobic Sprint Test and 400-meter sprint test was performed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study was to investigate the effect of caffeinated chewing gum on 400-meter sprint performance. 20 trained sprinter were divided into caffeine Gum trial (CAF) and Placebo trial (PL) with a randomized, double-blind study design. The participants chewing either caffeine Gum (CAF trial, containing 3 mg/kg of caffeine) or Placebo Gum (PL) for 10 minutes. After rested for 15 minutes, the participants underwent a Running-Based Anaerobic Sprint Test. After a 30-minute break, a 400-meter sprint test was performed. The blood lactate concentration were collected before and after 400-meter sprint from finger. Saliva samples were predicted to be collected before chewing gum, before the RAST, and after a 400-meter sprint. Saliva samples will be analyzed for caffeine and α-amylase concentrations in saliva.
