Brief Summary

The aim of the study being to investigate the effects of caffeinated chewing gum on shot put performance

Detailed Description

15-20 active throwers who have received professional shot put training are expected to be recruited for the study. In a randomisation crossover design, the study was divided into caffeinated chewing gum trial (CCG) and placebo trail (PL). Participants wore a heart rate monitor to record their heart rate and heart rate variability during the experiment, and were given either a caffeinated chewing gum containing 3 mg/kg of body weight (CAP trial) or a placebo chewing gum, and rested for 15 minutes. After the warm-up, the athletic ability test and shot put performance were conducted in order. Saliva samples were collected for analysis of caffeine and α-amylase before and at the end of the experiment.
