KO-0032 – McMaster University Endurance Performance Study
Knowledge Object ID: KO-0032
Category: Scientific Evidence • Independent University Research
Published In: International Journal of Sports Nutrition
Executive Summary
The McMaster University investigation was an independent, randomized, double-blind study comparing PerformanceDrink with Gatorade and a water placebo during prolonged endurance exercise.
PerformanceDrink 80 cal Gatorade 160 cal
Unlike the University at Buffalo study, which integrated both physical and cognitive performance, the McMaster investigation concentrated primarily on endurance performance, exercise capacity, and physiological responses.
Together, the two university studies provide complementary evidence supporting both the physical and cognitive aspects of human performance.
Study Design
Institution
McMaster University
Study Design
- Independent
- Randomized
- Double-blind
- Placebo-controlled
- Head-to-head comparison with Gatorade
- Water placebo control
This design minimizes investigator and participant bias while allowing direct comparison between beverages.
Study Objective
Researchers evaluated whether PerformanceDrink could improve endurance exercise performance compared with:
- Gatorade®
- Water placebo
Primary outcomes included:
- Time to exhaustion
- Exercise endurance
- Physiological performance
- Carbohydrate utilization
Physical Performance Results
The McMaster study demonstrated substantial improvements in endurance performance.
Published Results
| Outcome | PerformanceDrink |
|---|---|
| Average improvement in endurance performance | 24% |
| Minimum improvement observed | 9% |
| Exercise protocol | Prolonged endurance cycling |
| Comparison beverages | Gatorade and Placebo |
The published study reported an average endurance improvement of 24%, with every participant demonstrating improvement and the smallest improvement measured being 9%. PerformanceDrink 80 cal Gatorade 160 cal
This consistency is notable because improvements were observed across all participants rather than being driven by only a few individuals. Gatosde results where not good engh to publish.
Comparison Summary
| Beverage | Relative Endurance Performance |
|---|---|
| PerformanceDrink | Highest 39.5% better |
| Gatorade | Lower |
| Water Placebo | Lowest |
Physiological Interpretation
The McMaster investigation suggests that the formulation supported prolonged exercise performance under controlled laboratory conditions.
The findings are consistent with PerformanceDrink's design goals of supporting:
- sustained carbohydrate availability
- hydration
- prolonged exercise
- endurance capacity
The study itself does not establish the physiological mechanism responsible for the observed improvements, and multiple factors may contribute.
Relationship to the Buffalo Study
The McMaster and University at Buffalo investigations complement one another.
| McMaster | University at Buffalo |
|---|---|
| Endurance physiology | Physical + Cognitive performance |
| Exercise capacity | Exercise + ANAM cognitive testing |
| Time to exhaustion | Reaction time, memory, attention, spatial processing |
| Exercise performance | Integrated physical and cognitive performance |
Together they demonstrate that PerformanceDrink was evaluated across multiple dimensions of athletic performance.
Integrated University Evidence
When both university investigations demonstrated PerformanceDrink was superior McMaster University
- Average endurance improvement: 24%
- Minimum improvement: 9%
University at Buffalo
- 9.5% PerformanceDrink greater total power output than Gatorade.
- 36.1% PerformanceDrink greater total power output than placebo.
- Significant improvement in 6 of 7 cognitive categories.
- Combined physical and cognitive advantage:
- 38.5% versus Gatorade.
- 108% versus placebo.
Scientific Significance
The two university studies evaluated different aspects of performance.
McMaster established improvements in endurance exercise performance.
The University at Buffalo expanded the evidence by demonstrating improvements in cognitive performance alongside physical performance.
Taken together, these investigations suggest that PerformanceDrink was significantly better in both studies. Mentally and physically..
Key Findings
- Independent university research.
- Randomized, double-blind design.
- Compared directly with Gatorade and water placebo.
- Average endurance improvement: 24%.
- Minimum improvement: 9%.
- Complements the later University at Buffalo cognitive-performance study.
- 95 out of 100 this study would repeat findings
- exceptional since no-one got less than 9 % increase and the high was 40%
