Ever wondered if your morning cup of coffee could actually improve your golf game?

Some scientists wondered the same thing.

In a peer-reviewed study published in Medicine & Science in Sports & Exercise, Petey W. Mumford and colleagues tested the effects of caffeine on golf performance and fatigue.

Here’s what the researchers found, and how it might change your approach before teeing off. 

The Study Setup

This was a double-blind, placebo-controlled study.

• Participants: Single digit male golfers

• Format: Simulated tournament (36 holes, walking, stroke play, $1000 prize pool to help ensure a competitive event)

• Intervention: Caffeine group vs placebo group

• Dose: 1.9 mg of caffeine per kilogram of body weight, taken twice (once before the round, once at the turn)

This put total intake at approximately 3.8 mg/kg, split into two smaller doses for more stable energy throughout the round. (3.8 mg/kg is about two or three eight ounce cups of coffee for the typical person)

Researchers measured:

1. Score

2. Driving distance

3. Greens in regulation

4. Perceived fatigue and energy levels

What They Found

1. Performance improved.
Golfers who took caffeine had significantly better scores, longer drives, and hit more greens in regulation compared to the placebo group.

2. No downside to accuracy/control.

3. Caffeine reduced fatigue.
Players in the caffeine reported lower levels of physical and mental fatigue and higher feelings of energy during the round. 

What This Means for Your Game

1. Caffeine may help you play better not just feel better.

2. Try it during practice rounds first.
Caffeine affects people differently. Use a similar dose (1.5 to 2 mg/kg) before a non-competitive round and evaluate your tempo, focus, and feel.

3. Consider splitting your dose.
The study gave half before the round and half at the turn. That steady approach may help reduce crashes or late-round jitters.

4. It’s not just about distance.
The mental edge matters. Caffeine may help with focus, alertness, and sustained performance deep into the round.
