2020: An unforgettable year as a runner…and ICU dietitian (part 1/2)

December 31, 2020 No Comments

Perhaps a little self-indulgent, but this year has been unforgettable for all the right and mostly wrong reasons, so here’s my month-by-month recap. I’m lucky that running is a constant in my life, and something I can turn to on even the hardest of days, so I’ve based this blog around that. January: Starting the year buzzing with optimism but still burdened by my terrible sense of direction, I got lost and missed the start of Whitstable parkrun, but caught up from the back and swore this year was definitely going to be the year I got to my first […]

Where ICU meets sports nutrition

Where ICU overlaps with sports nutrition

Isn’t it bizarre how trivial conversations or moments can stick in your head? I often think back to such a moment in September 2019… Despite having promised to myself in 2013 that my life in academia was finally over, having qualified as a Registered Dietitian, there I was in the classroom again, ready for Exercise Physiology – the first module of my Applied Sports Nutrition postgrad. Most of the students on my side of the course had a nutrition background of some description (while the other side had a sports background), including a sprinkling of dietitians with differing levels of clinical […]

Swimming as cross-training for an injured runner

(Because obviously, after a fortnight of injury, I am an expert on the subject…) For the first time in 10 years of running, I think I have an overtraining injury. Alternatively, it might just be something small and acute that I’m overreacting to (fingers crossed), but either way, my hip hurts when I run, and even when I walk for more than about half an hour, so I’m not taking any chances until I get more professional advice (and ideally, a diagnosis). On a weekend when I was supposed to be helping to pace a friend (and client) round his […]

Keto diets in endurance exercise (part II)

October 3, 2020 No Comments

I introduced the definitions and basic theory underpinning endurance athletes’ ketogenic diets (EAKD) in the first blog, but what happens when the theory is subjected to scientific research? A recently published systematic review (which by definition should incorporate all relevant, good quality studies) will help us answer this question. I will warn you that this is quite a detailed synopsis, so feel free to skip to my ‘take home thoughts’ at the end if what comes before is a bit too heavy. The review claims to be the first of its kind looking at EAKD and key outcomes for endurance […]

Ketogenic diets in endurance exercise (part I)

September 24, 2020 No Comments

Ketogenic diets have been used as an established treatment for epilepsy (particularly among children) for many years, but more recently there’s been a much broader interest in going ‘keto’, especially in certain dubious corners of social media. Most of the attention is based on its potential as a weight-loss tool, but there has also been a growing buzz about its capacity for performance-enhancement in endurance exercise. I’m not going to comment on the former here (especially as it has always seemed to me an unnecessarily restrictive approach to weight management…although each to their own), but I have been meaning to blog on the latter for […]

Running in 2020 / virtual races

September 5, 2020 No Comments

So virtual races are now a thing, and they’ve certainly stirred up some strong opinions out there in the running community. Here are mine! (Apologies for the London bias of this piece) Overall, I think it’s a positive move. It’s all well and good using running for routine, relaxation and to stay sane (and I can say with some certainty that I would have struggled to achieve any of those 3 in 2020 without it), but competition is important. For some people, keeping fit, pushing themselves in training or following a strict schedule are sufficient running goals in themselves, but […]

Dietary nitrates and endurance exercise – blog 3 and summary

March 8, 2020 No Comments

Well done and thank you for getting this far – I know it’s been stodgy and technical at times, but this third and final nitrates blog should tie it all together nicely. I’ve already covered the impact of exercise assessment type, athlete fitness level, dosage and timing on nitrate’s benefit to endurance performance. The final elements to consider are sport type, intensity and duration, after which I will summarise where we are with some practical tips. In blog 1 I mentioned that nitrate seems to be more effective in sub-maximal ‘time to exhaustion’ assessments than maximum effort time trials. Somewhat […]

Dietary nitrates and endurance exercise – blog 2

February 28, 2020 No Comments

In the intro blog, I explained why nitrates had attracted plenty of interest in endurance performance research, and introduced the idea that they may be more effective in improving the efficiency of sub-maximal efforts. Another emerging theory is that the ergogenic (performance-enhancing) impact of nitrates is felt more strongly among recreational athletes. This trend was spotted in one of the early meta-analyses, where there was a large discrepancy in the percentage of trials showing positive results between those involving ‘untrained’ and ‘trained’ participants. An individual study was then designed to look more closely at this, and it found that beetroot […]

Dietary nitrates and endurance exercise – intro blog

February 20, 2020 No Comments

As a curious runner but sceptical scientist, I’m easily drawn to news pieces about enhancing running performance, particularly those that relate to nutrition. I try to view the articles through two pairs of eyes – my own (to critique the evidence and how it’s presented), and perhaps more importantly, those of a running friend or potential client. It’s vital to consider how they would interpret the article, and what questions might soon come my way. Beetroot juice is a fine example of running nutrition grabbing the headlines in recent years. I had already been following the media stories with interest, […]
