The effect of caffeine on muscular power during resistance training 💥
Details on where caffeine supports lifting performance.
Effects of acute caffeine intake on muscular power during resistance exercise: a systematic review and meta-analysis
Study Details
This new meta-analysis compiled data from 12 studies (230 participants) to establish the effects of caffeine supplementation on muscular power-related variables 📚
Here are the key findings ⬇️
Key Findings
💊 Caffeine doses varied from 3 to 12 mg/kg
🏋️ Participants were either resistance-trained or recreationally active
Analysis showed that caffeine supplementation significantly improves…
⚡️ Mean lifting velocity
📈 Mean power output
Greater improvements in mean power were observed in males vs females 🙋♂️
…and with caffeine doses < 3 mg/kg/day 💊
Caffeine also significantly increases mean lifting velocity at all…
☕️ Caffeine doses (low to high)
💪 Muscle groups
📊 Exercise loads
With no significant differences observed between subgroups (incl. sex and habitual caffeine consumption) ❌
Conclusion
Caffeine ingestion enhances movement velocity and power output during resistance exercises, regardless of load ✅
With males experiencing a greater benefit than females 🔍
