Compares people who got the treatment with people who did not.
- Who or what was studied
- 14 healthy male cyclists, mean age 45.6
- Design
- Double-blind crossover
- Dose
- Low-dose marine protein hydrolysate added to a whey protein and carbohydrate recovery drink; exact dose not given in the abstract
- Duration
- Four hours of recovery between two high-intensity cycling sessions
What it found
Time to exhaustion in the second session did not differ significantly between the drink with marine protein hydrolysate and the same drink without it (mean difference 0.85 min, p = 0.156), and heart rate, respiratory exchange ratio, blood lactate and glucose did not differ either.
What it doesn't show
A small study at a low dose, in trained middle-aged men and short-term recovery only. It cannot rule out an effect at other doses or over longer training.
Funding and conflicts of interest
Funded by Firmenich Bjørge Biomarine A/S, whose representative was a co-author and composed the diets. The authors say the study was double-blinded and the statisticians did not know the diet order until the analyses were complete.
