Jumbo-Visma is pushing the limits in nutrition at the Tour and ketones are a great example of that. What are ketones and what role do they play in the nutritional strategy of the team?<\/strong><\/p>\n

<\/p>\n

The role of ketone supplements<\/strong><\/h2>\n

Ketones are used as an energy source in your body when glucose is not available. Your body produces ketones naturally when you\u2019re fasting, eating a low carbohydrate diet or going for a really long bike ride. Ketones can also be ingested in a form of a supplement. Just like you have an energy drink filled with sugar glucose, some cyclists at the Tour de France<\/a> will use drinks filled with ketones.<\/p>\n

Research shows that ketone supplements reliably increase blood ketone levels. This can be used in training to enhance adaptation. Ketone supplements consumed with carbohydrates may also enhance recovery by improving glycogen re-synthesis which is particularly important at the Tour. Some claim that supplemental ketones might even improve endurance performance<\/a> but research doesn\u2019t currently support that.<\/p>\n

Jumbo-Visma among the first to use ketones<\/strong><\/h2>\n

In 2018, rumours started circulating that some teams at the Tour de France might be using ketones as a part of their nutrition. Jumbo-Visma was among the first to confirm that ketones are a part of their strategy. And it seems like the team stuck to it. At a press conference at the 2020 Tour de France,<\/a> Primo\u017e Rogli\u010d confirmed but wasn\u2019t really convinced about the effects: \u201cYeah, we are still using it. For the real effects, it\u2019s really hard to say. It\u2019s hard to feel it.\u201d<\/p>\n

Why do they use ketones?<\/a><\/strong><\/h2>\n

Asker Jeukendrup, head of nutrition at Jumbo-Visma, confirmed that the use of ketones is based on good thinking but the research isn\u2019t there yet.<\/p>\n

\u201cThe use of ketones is still experimental. There are few studies to go by. It\u2019s the same rationale that I experimented with during my PhD 25 years ago but with medium chain triglycerides (MCT). These are partly converted to ketone bodies. We demonstrated that MCTs were rapidly used and they could be a good alternative fuel. However, it\u2019s pointless even thinking about additional fuels if you don\u2019t have a perfect fuelling plan in the first place.\u201d<\/p>\n

And this is exactly what Jumbo-Visma did. They took their excellent fundamentals and added ketone supplementation on top.<\/p>\n

In pursuit of marginal gains<\/a><\/strong><\/h2>\n

Grischa Niermann, Jumbo-Visma sports director, said that ketone supplements are just a small part of the team\u2019s complex performance puzzle rather than being the miracle pill that so many hope it to be.<\/p>\n

\u201cI think a lot of people think ketones are a wonder drug, and it makes you go faster by 20%. And I think that\u2019s total bullsh*t. If you use it, you believe that it has some effect somehow but I\u2019m 100 % convinced that it\u2019s not the wonder supplement that makes you go faster by a big, big margin.\u201d<\/p>\n

Jumbo-Visma centres nutrition around their Foodcoach app powered by machine learning. It ensures they are always covering the riders\u2019 basics. They were at the frontline with the use of glucose monitors as well as the introduction of ketones. They are searching for marginal gains which is a direction pioneered by Team Sky.<\/p>\n

\u201cThat strategy includes a lot of other things, especially our Foodcoach app where we really measure and calculate everything that the riders take in on a daily basis, everything they burn, and what they should eat. Ketones are one of the puzzle pieces in the entire recovery plan. For some, ketones add something for recovery, for other riders less. You have to get the whole puzzle right to create any benefit,\u201d explained Niermann.<\/p>\n","protected":false},"excerpt":{"rendered":"
