Effects of caffeine and sodium bicarbonate on resistance training performance
The Effect of Acute Caffeine and Sodium Bicarbonate Supplementation on Upper and Lower Submaximal Resistance Training Performance
This study is testing whether caffeine and sodium bicarbonate can help people perform better during resistance training exercises like bench presses and knee extensions.

What this trial studies
This research explores how caffeine and sodium bicarbonate supplements affect short-term resistance training performance. Using a randomized, double-blind, placebo-controlled, cross-over design, the study will assess their impact on muscle activation, speed of movement, and fatigue during exercises like knee extensions and bench presses. Participants will undergo three separate visits to test the effects of each supplement compared to a placebo, measuring parameters such as peak force, movement velocity, and repetitions to failure. Blood lactate levels will also be monitored to evaluate physiological responses.
Who should consider this trial
Good fit: Ideal candidates are healthy, physically active males and females aged 18-40 with regular resistance training experience and daily caffeine intake.
Not a fit: Patients with recent musculoskeletal injuries may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance resistance training performance for athletes and fitness enthusiasts through effective supplementation.
How similar studies have performed: Previous studies have shown positive effects of caffeine on athletic performance, suggesting potential success for this approach.
