Area of Science:

  • Exercise Physiology
  • Sports Nutrition
  • Human Performance

Background:

  • Caffeine is a widely used ergogenic aid.
  • Its effects on upper-body resistance exercise performance require further investigation.

Purpose of the Study:

  • To examine the effects of caffeine on upper-body resistance exercise performance and perceptual responses.

Main Methods:

  • Fifteen men completed three lab visits involving 1-repetition maximum testing and resistance exercises (barbell bench press, incline barbell bench press, dumbbell bench press) under caffeine (800 mg) or placebo conditions.
  • Perceptual measures including arousal and vigor were recorded throughout the workouts.

Main Results:

  • Participants completed significantly more repetitions per set for the barbell bench press and incline barbell bench press when consuming caffeine compared to placebo.

  • Higher arousal and vigor scores were reported in the caffeine condition both before and during the workout.

    • Conclusions:

    • Caffeine demonstrates an ergogenic effect on upper-body resistance exercise performance.
    • Positive impacts on workout perception, including increased vigor and arousal, may contribute to these performance enhancements.
