Hypothesis
How does creatine ethyl ester supplementation combined with resistance training affect body composition and muscle performance?
Conclusion
Creatine ethyl ester was not as effective as creatine monohydrate in increasing muscle strength and performance.
Supporting Evidence
- Serum creatine levels were significantly higher in the creatine monohydrate group compared to the creatine ethyl ester group.
- Total muscle creatine content was significantly higher in the creatine monohydrate group compared to the placebo group.
- Significant increases in body mass were observed over the course of the study.
Takeaway
This study looked at whether a new type of creatine helps people get stronger when they lift weights. It found that it doesn't work better than the regular kind of creatine.
Methodology
Participants were randomly assigned to receive either a placebo, creatine monohydrate, or creatine ethyl ester while undergoing a resistance training program for seven weeks.
Potential Biases
Potential bias due to the self-reported dietary intake and compliance monitoring.
Limitations
The study only included non-resistance-trained males, which may limit the generalizability of the results.
Participant Demographics
30 non-resistance-trained males with a mean age of 20.43 years.
