Hypothesis
The dietary supplement will result in an increase in norepinephrine, markers of lipolysis, and metabolic rate in resistance trained men compared to a placebo.
Conclusion
The dietary supplement leads to an acute increase in plasma norepinephrine and markers of lipolysis, as well as metabolic rate, without significant changes in hemodynamic variables.
Supporting Evidence
- The dietary supplement increased norepinephrine levels significantly compared to placebo.
- Glycerol and free fatty acids also showed significant increases with the supplement.
- Total kilocalorie expenditure was 29.6% greater with the dietary supplement than with placebo.
Takeaway
Taking this dietary supplement can help your body burn fat and use energy better, especially for people who lift weights.
Methodology
Ten resistance trained men ingested either the dietary supplement or a placebo in a double-blind, crossover design, with blood samples taken at various intervals to measure biochemical markers.
Potential Biases
The study was funded by the manufacturer of the dietary supplement, which may introduce bias.
Limitations
The study was limited to a small sample size of young, healthy, and lean men, which may not represent the general population.
Participant Demographics
Ten healthy, resistance trained men, average age 27 years, BMI 25 kg/m², body fat 9%.
