Study Details

This new study recruited 12 elite male wrestlers who completed four exercise test sessions with…

1️⃣ Placebo

2️⃣ Caffeine (3 mg/kg)

3️⃣ L-theanine (3 mg/kg)

4️⃣ Caffeine + L-theanine (both 3 mg/kg)

Caffeine + l-theanine outperformed placebo for…

✅ Wall squat time

✅ Medicine ball throw

✅ Vertical jump height

✅ Grip strength

✅ Reaction time

✅ Cognitive testing accuracy

Specific Wrestling Fitness Testing was also highest in the caffeine + l-theanine condition 🤼

😰 Caffeine increased anxiety vs placebo

Whereas, caffeine + l-theanine reduced anxiety to below placebo levels (8% incidence vs 33%) 📉

🫀 The prevalence of caffeine-induced tachycardia (“fast heart rate”) (92%) was notably reduced under caffeine + l-theanine conditions (17%)
