Why would an athlete in a weight lifting competition consider using a caffeine supplement 30 minutes prior to the event?

  1. The availability of fat stores will be stimulated so that they can be used as a source of fuel.
  2. The athlete will retain fluid levels, improve their glycogen stores and feel less fatigued.
  3. The central nervous system will be stimulated, increasing trait anxiety and improving concentration.
  4. The central nervous system will be stimulated, increasing the release of adrenaline and enhancing muscular contractions.
