Relative energy deficiency in sport (RED-S) is an issue of increasing concern in sports and exercise medicine. RED-S impact exercisers of all levels and ages, particularly where low body weight confers a performance or aesthetic advantage. Key to mitigating adverse health and performance consequences of RED-S is supporting athletes and dancers to change behaviours. These infographics aim to assist clinicians in communicating the concepts to exercisers and in implementing effective management of athletes in their care.
Figure 1 illustrates the concept of energy availability (EA) in RED-S. Preferentially energy derived from dietary intake covers the demands of training and the remaining energy, EA, is, quantified in Kcal/Kg of fat free mass. In Figure 1, the central bar illustrates adequate EA in an athlete where energy intake is sufficient to cover the demands of training and fundamental life processes to maintain health. Conversely, low energy availability (LEA) is a situation of…
Our most recent coaches corner podcast discussed “getting your diet back on track” as the intro topic.
I did my best to give you some practical tips, sensible questions to ask yourself, and actionable advice for bringing your diet back inline with your training goals.
This topic is something very relevant to those athletes in the midst of their race preparation season; where the race is still a little while off, and motivation for diet dictatorship has slipped, resulting in a (slight) deviation from the clean eating you started off with.
None of us are perfect; and perfection isn’t something that I recommend as it is linked with obsessive eating and exercise tendencies and these are a product of unhappiness to be honest. When the balance goes obsessive tendencies start to appear. there is only so long that you can hold yourself to dogmatic diet practices; something gives.

Vaccines are argued by people who hang on to an extreme view either side instead of a middle ground that accepts the pros and cons and that we have a lot more research to do. This specially relates to why some population groups are susceptible to side effects (? genetics? gut microbiome? impact of multiple vaccines, adjuvant side effects etc) and why the vaccines may be impacting the development of natural immunity to the right things and so on. We have a lot of questions in the field of vaccine science and to claim that vaccines are safe is not a done deal at all!
We don’t know enough… and we know quite a bit, and we need to know more to protect sensitive populations from extreme and life changing adverse effects. Period. Don’t argue here… just read and add it to your repertoire of knowledge…
And this science article documents some of the areas we must keep exploring… it is also a good but complex read; because it is complex! This is the type of reading I suspect many on the PRO fence are not reading.
Adversomics: a new paradigm for vaccine safety and design
Despite the enormous population benefits of routine vaccination, vaccine adverse events and reactions, whether real or perceived, have posed one of the greatest barriers to vaccine acceptance—and thus to infectious disease prevention—worldwide. A truly integrated clinical, translational, and basic science approach is required to understand the mechanisms behind vaccine adverse events, predict them, and then apply this knowledge to new vaccine design approaches that decrease, or avoid, these events. The term “adversomics” was first introduced in 2009 and refers to the study of vaccine adverse reactions using immunogenomics and systems biology approaches. In this review, we present the current state of adversomics research, review known associations and mechanisms of vaccine adverse events/reactions, and outline a plan for the further development of this emerging research field.
Great article, worth a read if you work with athletes or are an athlete with ongoing issues with your menstrual cycle. Unfortunately it is not ok to not have periods. Long term amenorrhoea can have consequences in many body systems. It is important that we determine why there are issues and then go from there.
Menstrual periods are a barometer of healthy hormones. The evolutionary purpose of ovulation is to reproduce. Furthermore the carefully biologically choreographed variation of hormones that occurs during an ovulatory menstrual cycle is crucial to health and athletic performance.
Why? Hormones are chemical messengers that have far reaching effects throughout the body and drive the beneficial adaptations to exercise. In the case of menstrual cycles, the fluctuations of oestrogen and progesterone are key to this process. The effects of these sex steroids go far beyond reproduction. These hormones play important roles in bone strength, cardiovascular health, optimal lipid profile and production of neurotransmitters to regulate mood. The effects of low levels of oestrogen and progesterone are well documented in menopausal women who experience loss in bone mass, risk of osteoporosis and fracture, together with an increase risk of cardiovascular disease.
If ever you doubted the important interactions between the diet, pathogens, the gut microbiota and our own attitude to and skills developed to counter stress then this article shines a light on all these topics of huge importance.
The gut is the first place I explore with almost every client with chronic health issues, because it is usually the start of where many health issues unravel.
“stress-induced variations in the gut microbiota can modulate final resilience outcomes, particularly in terms of mental health.”
