Hypothesis
Can creatine monohydrate and conjugated linoleic acid enhance strength gains and improve body composition in older adults following resistance exercise training?
Conclusion
The study found that creatine and CLA supplementation during resistance training significantly improved strength and body composition in older adults.
Supporting Evidence
- Resistance exercise training improved all measurements of functional capacity.
- Creatine and CLA supplementation led to greater increases in fat-free mass and reductions in fat mass.
- Participants on the supplement showed greater improvements in muscular endurance.
Takeaway
Older people who took creatine and CLA while exercising got stronger and lost fat better than those who didn't.
Methodology
The study involved 39 older adults who completed six months of resistance training with either creatine and CLA or a placebo in a randomized, double-blind design.
Potential Biases
Potential bias in self-reported dietary intake and compliance with supplement consumption.
Limitations
The study did not include a non-exercised control group and the long-term effects of supplementation were not assessed.
Participant Demographics
Older adults aged 65-85, including 19 men and 20 women.
