Players love to discuss which supplements give them the most bang for their buck. Two of the most popular are creatine and caffeine—but do they truly help racquet‑sport athletes? This article separates the facts from the hype.
Creatine: Building Explosive Power
Pros
-
Boosts short‑burst power and strength, helping with quick direction changes, serves and smashes.
-
Supports hydration inside muscle cells, contributing to muscle fullness and nutrient delivery.
-
May aid cognitive function and long‑term muscle health when used consistently.
Cons
-
Tennis‑specific research shows no immediate improvement in serve speed or stroke precision during a match.
-
Some people experience water retention or minor digestive upset.
-
Benefits accrue over weeks, so it’s less useful as a “day‑of” boost.
How to Use
-
Take 3–5 grams daily, ideally at the same time each day. Maintenance dosing is more important than timing.
Caffeine: The Immediate Game‑Changer
Pros
-
Increases alertness, reaction time and perceived energy.
-
Studies in racquet sports indicate improved serve speed and hitting accuracy when taken before play.
-
Helps maintain stroke quality under fatigue.
Cons
-
May disrupt sleep if taken within six hours of bedtime.
-
Can cause jitters or stomach upset in sensitive individuals.
How to Use
-
Consume 2–3 mg per kilogram of body weight (e.g., 150–225 mg for a 75 kg athlete) 30–60 minutes before play.
-
Options include coffee, caffeinated gels or capsules.
Choosing What’s Right for You
-
For training blocks: Creatine helps you push harder during strength sessions and can indirectly improve your on‑court power.
-
For match day: Caffeine delivers quick improvements in focus, reaction time and stroke quality. Test it in practice to gauge your tolerance.
-
Combination: Some athletes use both—creatine daily for long‑term benefits and caffeine selectively before competitions.
