The ketone drink
A group of top international rowers were given it shortly before they rowed on fixed machines in a lab.
After half an hour of hard rowing, those getting the Drink had rowed on average 50m further in the same time than when they had a dummy drink. This was an improvement of 0.5 per cent. It can be the difference between silver and gold.
Dr Scott Drawer, head of research at UK Sport, who helped design the trial, said: ‘Ketones have been ignored as an energy source in sport. We need to look at them seriously.’
Patent application title: HYDROXYBUTYRATE ESTER AND MEDICAL USE THEREOF
Inventors: Kieran Clarke (Oxford, GB) Richard Lewis Veech (Rockville, MD, US)
Assignees: ISIS INNOVATION LIMITED Government of the USA, as Represented by the Secretary , Department of Health And HUMAN SERVICES
In this study, we determined the kinetic parameters, safety and tolerability of (R)-3-hydroxybutyl (R)-3-hydroxybutyrate, a ketone monoester administered in the form of a meal replacement drink to healthy human volunteers.”
so the basic gist here is
does UK sport and therefore SKY have access to a proprietary ketone drink?
is it safe ?
is it performance enhancing ?
possibly (from unpublished rowing data 0.5% over 30 min)
how could ketone supplementation work?
competitively inhibitting carbohydrate metabolism in the Citric Acid cycle
per unit of ketone vs carbohydrate
ketone supplementation could yield more energy
since acetoacetate spontaneously breaks down to acetone
which can not be converted back to a useful energy source
rather than being stored
the net effect
