Hypothesis
When consumed in the days after eccentric exercise, collagen hydrolysate would reduce ratings of delayed onset muscle soreness and improve muscle function recovery compared to dairy protein and a placebo.
Conclusion
The post-exercise consumption of collagen hydrolysate or dairy protein does not improve recovery from exercise-induced muscle damage compared to a placebo.
Supporting Evidence
- Muscle soreness increased after downhill running across all treatments.
- Significant time effects were observed for muscle function measures, but no treatment effects were found.
- Blood markers of muscle damage peaked at 24 hours post-exercise but showed no treatment differences.
Takeaway
This study found that taking collagen or dairy protein after tough exercise doesn't help your muscles recover any faster than not taking anything at all.
Methodology
Thirty-three active males consumed either collagen hydrolysate, dairy protein, or a placebo after eccentric exercise, with various measures taken to assess muscle damage and recovery.
Potential Biases
Potential bias due to lack of control over dietary protein intake and the specific demographic of participants.
Limitations
The study did not control participants' dietary protein intake during the intervention period and only included recreationally active males.
Participant Demographics
Thirty-three active, healthy males aged 18-40 who exercised at least twice a week.
