Dr Stuart Gray's main area of focus is in uncovering strategies to counteract the age related loss of muscle mass, known as sarcopenia, and associated metabolic disorders. Recent research has focused on the combined effects of resistance exercise and omega-3 fatty acids. He also attempts to used novel analytical techniques to further our understanding of the mechanisms underlying sarcopenia.---This podcast episode is sponsored by Fibion Inc. | The New Gold Standard for Sedentary Behaviour and Physical Activity MonitoringLearn more about Fibion: fibion.com/research---Physical Activity Researcher Podcast have created a ‘Purchase Guide for Researchers: Accelerometer-based Activity Trackers’.
