Nutrition: The Fuel Behind Elite Performance

In Olympic preparation, every detail matters. Nutrition often invisible to the public eye is nevertheless one of the fundamental pillars of physical, mental, and decision-making performance.

The nutritionist does far more than simply design meal plans. They analyze, measure, adapt, and personalize. They build a tailor-made nutritional strategy that allows the athlete to perform day after day… and race after race.

1. Two Environments, Two Ways of Fueling the Body

In Olympic sailing, nutrition must respond to two very different contexts.

On Land: Fueling the Body to Withstand the Training Load

Nutritional needs focus on:

• • • recovery

    • physical preparation

    • energy balance

    • injury prevention

The objective is clear: arrive at training in optimal condition and absorb the training workload effectively.

At Sea: Eating Under Extreme Constraints

This is where everything becomes more complex:

• • • long hours on the water

    • no real lunch break

    • constant energy demand

    • changing weather conditions

    • very little time between races

Nutrition must therefore be:

• • • simple

    • easily digestible

    • practical

    • easy to store

    • quick to consume

Adapting nutrition to environmental constraints is a decisive factor in sustainable performance.

2. The Nutritional Challenges of Olympic Sailing

Sailing creates very specific constraints:

• • • several hours of continuous effort

    • exposure to wind, salt, cold, or heat

    • constant intensity variations

    • emotional and cognitive load

Under these conditions, nutrition becomes a true strategic lever.
This is why the nutritionist’s work is essential to:

• • • plan ahead

    • test foods in real conditions

    • adapt to individual preferences

    • guarantee comfort, energy, and digestibility

And yes, comfort is also part of performance.

3. Advanced Personalization: The Power of Data

The role of the nutritionist goes far beyond designing menus.

In my own team, our nutritionist regularly went out on the water with us.
She carried out:

• • • blood tests before, during, and after training

    • land vs. sea comparisons

    • analyses under different weather conditions

This scientific approach made it possible to understand:

The real needs of each athlete based on their body, effort, and environment

She also worked hand in hand with my fitness coach to synchronize:

• • • energy intake

    • muscle mass objectives

    • recovery strategies

    • supplement choices

The result: a fully personalized, precise plan, continuously adjusted.

4. Hydration: One of the Most Underestimated Performance Factors

Hydration is a critical element yet it is often neglected.

❄️ Cold = Reduced Sensation of Thirst
Sailors drink less → cramps, loss of clarity, impaired decision-making.

☀️ Heat = High Risk of Severe Dehydration
During racing, focus sometimes prevents athletes from drinking enough.

Direct consequences:

• • • reduced vigilance

    • slower cognitive processing

    • tactical errors

    • accelerated fatigue

    • poor recovery

Poor hydration at the start of a regatta can impact… the entire week of competition.

Here, the nutritionist plays a key role:

• • • quantities

    • frequency

    • supplements

    • absorption

Nothing is left to chance.

5. The Nutritionist: Guardian of Performance… and Ethics

Another fundamental aspect of the nutritionist’s role is anti-doping prevention.

The nutritionist guarantees:

• • • product compliance

    • supplement analysis

    • nutritional safety

    • respect for anti-doping regulations

They therefore become an essential partner in protecting:

• • • the athlete’s health

    • their career

    • and their values

Conclusion: A Discreet but Decisive Role

Nutrition is far more than a “bonus” in Olympic sailing.
It is a fuel, a stabilizer, a recovery accelerator, and a key driver of mental clarity.

Feeding an athlete properly means enabling them to:

• • • sustain physical effort

    • remain mentally sharp

    • make better decisions

    • avoid injuries

    • perform sustainably over time

In business as well, energy, recovery, and long-term performance capacity are central.
