Caffeinated Chewing Gum on 400-meter Performance

August 3, 2024 updated by: Chih-Hui Chiu

Effects of Caffeinated Chewing Gum on 400-meter Performance and Fatigue Index of Sprinters: a Crossover Trial

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

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.
