On this episode, we discuss with Dr Margo Mountjoy all about RED-S (Relative Energy Deficiency in Sports). Now the consequences of an athlete being in this state can include not only performance detriments but also health side effects.

In 2014, the International Olympic Committee led by today's featured expert Dr Margo Mountjoy, published a consensus statement entitled “Beyond the female athlete triad relative energy deficiency in sport”, and this paper explored the syndrome of RED-S being impaired physiology caused by relative energy deficiency resulting impairments was stated to include effects on metabolic right menstrual function, bone health, immunity, protein synthesis and cardiovascular health with the key driving factor of this syndrome relative energy deficiency in sport being low energy availability.

During this episode Dr Margo Mountjoy shares around the origins of coining the phrase relative energy efficiency in sport as she worked with the IOC medical committee, we explore the signs and symptoms of RED-S for athletes. Dr Mountjoy outlines the incidence and prevalence of relative energy deficiency in sport amongst endurance athletes and athletes in general and the prevalence has been reported to be up to 60% amongst athletes in endurance events. Dr Mountjoy outlines how to screen for RED-S, the treatment of RED-S once it's been identified, how to lose weight and stay in energy balance, returning to sport post pregnancy and of course there's the issuing of this week's physical challenge as well.
