I’ve a query for you.

What proportion of feminine runners do you suppose have Low Vitality Availability (LEA)?

5%? Perhaps 10?

Maybe you’re pondering greater, 20 – 25%?

A brand new examine suggests you would possibly nonetheless be a way off! Whitney et al. (2024) assessed 1030 Boston marathon runners utilizing self-reported surveys to evaluate for LEA.

Of their examine, 42.5% of feminine runners had been classed as having Low Vitality Availability!

Should you’re not conversant in LEA it outcomes from an athlete not consuming sufficient power from their food regimen to fulfill the calls for of every day life and sport. It may possibly have detrimental results on a number of areas of well being and efficiency as highlighted within the examine abstract beneath:

That is such an essential paper and I’d encourage you to debate it with athletes in your care. It’s the biggest examine of its variety ever carried out at a real-world marathon occasion and the primary to exhibit a hyperlink between dietary “under-fuelling” and slower race efficiency occasions in addition to elevated danger of requiring race-day medical consideration.

There’s loads to take from this analysis so I’d encourage you to learn the complete paper, it’s open entry in BJSM and obtainable by way of this hyperlink.

The inhabitants included on this examine is a pleasant illustration of marathon runners you’re prone to see in clinic. The examine group was 53% feminine and 47% male, roughly 75% had been Boston Qualifiers and 25% charity group registrants.

We all know a number of elements can affect race day efficiency however it does appear that power availability was key:

It’s important that as well being professionals we’re conscious of Low Vitality Availability and the impression it might have on well being and efficiency. It’s a key driver of RED-S and could be related to consuming issues and train dependancy so it’s important that athletes have the assist they want, probably together with a Psychological Well being Skilled and referral to a Sports activities Doctor.

I’ve chatted with Dr Whitney by way of social media and he or she’s very kindly shared some nice info on indicators of LEA to look out for in athletes:

I requested Dr Whitney concerning the subsequent steps and he or she highlighted how essential it’s to rearrange a session with a Registered Dietician who specialises in sports activities efficiency because the power and diet wants of every athlete are advanced and extremely variable. Alongside this Dr Whitney shared some common recommendation that may be useful for athletes:

I like this clear, easy message from Dr Whitney and her analysis, “Fuelling is quicker!”

I feel we ought to be spreading this far and vast to well being professionals, coaches and athletes. So many issues with runners change into a part of the ritual of their sport, from proudly owning far too many pairs of trainers to warming up and beginning your GPS watch. It’s all a part of working and diet ought to be the identical, a part of that ritual. It may be a really pleasurable half too!

I encourage runners to have a post-run restoration and fuelling technique that they will stay up for, it helps them via the lengthy runs, particularly if it’s chilly and moist! For me it was a scorching chocolate, fruit, some good snacks and a soak within the tub. That grew to become a key a part of my ritual and one thing I cherished.
