Hypothesis
Does 5 days of creatine loading affect the electromyographic fatigue threshold in college-aged women?
Conclusion
Creatine loading significantly increases the electromyographic fatigue threshold in college-aged women.
Supporting Evidence
- Creatine loading resulted in a 14.5% increase in electromyographic fatigue threshold.
- The placebo group showed no significant change in fatigue threshold.
- Participants in the creatine group also experienced a significant increase in body weight.
Takeaway
Taking creatine for 5 days can help women exercise longer before getting tired.
Methodology
Participants were randomly assigned to either a creatine or placebo group and underwent a cycle ergometer test before and after supplementation.
Potential Biases
Potential bias due to the small sample size and the specific demographic of participants.
Limitations
The study only included college-aged women and may not be generalizable to other populations.
Participant Demographics
Fifteen healthy college-aged women, mean age 22.3 years.
