Pulling this project together was a major undertaking - including recruiting experts from across the world working both in academia and at the coal face in cycling. Really proud of what we have produced!

MitoQ supplementation does not impact redox responses to acute exercise in skeletal muscle of older individuals
Ageing is associated with attenuated exercise responses in skeletal muscle, which may be related to a failure of muscle redox signalling. The attenuat…

Like many others, I've moved over here from "the other place". I'm a researcher in exercise physiology and muscle metabolism, with an interest in how exercise and nutrition impact performance across the health spectrum. Looking forward to exploring this new platform and engaging in discussion!
