THE SHORT ANSWER
Dr Filip Larsen, exercise physiologist and chief scientific officer at nomio; researcher at the swedish school of sport and health sciences (gih) specialising in isothiocyanate compounds and exercise adaptations, has appeared on the Roadman Cycling Podcast. Here's where Larsen lands on in-ride fuelling. The positions below are drawn from those conversations, quoted directly.
WHO IS DR FILIP LARSEN?
Dr Filip Larsen researches the cellular machinery behind endurance — mitochondrial function and the compounds that influence it — and brings a scientist's scepticism to the supplement aisle. His work on what's actually inside the 'green shots' pros are using cuts through marketing to mechanism: what's plausible, what's measured, and what's hype. For Roadman's audience he's a useful filter on recovery and adaptation claims, anchoring the conversation in physiology rather than the latest pro fad.
LARSEN ON IN-RIDE FUELLING
Larsen’s key positions on in-ride fuelling.
- Endurance adaptation is mitochondrial — the aerobic base works by building the cell's energy machinery, not by magic.
- Most performance supplements are hype; a few are measured — judge them by mechanism and evidence, not pro endorsement.
- Recovery and adaptation are the same process viewed from two sides — the stimulus only counts once it's absorbed.
- Nitrate and similar compounds have plausible mechanisms but modest, individual effects — useful, not transformative.
IN LARSEN’S OWN WORDS
Verbatim from Dr Filip Larsen’s appearances on the podcast.
“So they trained trained really hard for one week. Uh and it was a randomized double blinded crossover study. So they trained like a one week super hard training. So it was basically 4 minute or 8 minute build to max intervals every day for one week. And I mean the intent was to uh to get them tired, slightly overreached and uh then let them recover for a few days and see how they bounce back.”
“So say the cycle at 250 watts or something if they had a threshold there. So after this tough week, they actually had a higher lactate level at the same workload when they got the placebo just because they didn't adapt to the training. But when they got the isotyanates in the normal drink, it was lower. So it was a big big difference there uh between how they responded.”
“They were given a like a small like a small experimental scar like in the like in the mouth somewhere. And they they done did that twice. So once was uh during you know summer break or whatever and once was before final exams. And they found out, okay, so during the exam period, the wound actually healed much slower than when you were not stressed. And that is, you know, so it's your mental stress levels, they will affect your physiological ability to recover.”
