Functional Infusions and Endurance Sports: A Scientific Guide for Runners and Cyclists

Introduction

In recent years, the world of sports nutrition has begun to rediscover the value of natural beverages. While for decades the focus was almost exclusively on synthetic supplements and energy drinks, today more and more athletes – both professional and amateur – are shifting their choices towards functional infusions rich in phytonutrients, polyphenols, and natural caffeine.

Runners, cyclists, and triathletes in particular are discovering that certain plants traditionally used in infusions can offer concrete benefits for energy, hydration, and recovery.

This context aligns with the growing scientific interest in ingredients like Yerba Mate, green tea, guarana, and antioxidant-rich fruits, increasingly used in endurance sports nutrition.

Endurance Sports: Metabolism, Energy, and Oxidative Stress

Endurance sports – such as running, cycling, triathlon, and cross-country skiing – require prolonged effort that primarily involves aerobic metabolism.

During activities exceeding 40-60 minutes, the body:

progressively consumes muscle glycogen

increases the production of free radicals

activates a hormonal stress response

requires constant hydration

Several studies published in sports nutrition journals show that oxidative stress significantly increases in endurance sports.

A review published in the Journal of the International Society of Sports Nutrition highlights that the supplementation of polyphenols and antioxidant compounds can contribute to improving recovery and adaptation to effort.

The Role of Hydration in Endurance Sports

One of the most underestimated factors in sports performance is the quality of hydration.

According to the
American College of Sports Medicine

a fluid loss of even just 2% of body weight can cause:

reduced aerobic performance

increased perception of fatigue

decreased concentration

For this reason, many athletic trainers suggest using beverages that not only provide fluids but also bioactive compounds useful for energy metabolism.

Functional infusions represent an increasingly interesting solution in this regard.

Yerba Mate: Natural Energy and Physical Endurance

One of the most studied ingredients in the field of sports nutrition is

Yerba Mate

a traditional South American infusion rich in:

natural caffeine (mateine)

polyphenols

saponins

B vitamins

Research published in Nutrients has shown that yerba mate consumption can increase fat oxidation during physical activity, promoting better management of energy reserves.

For this reason, yerba mate has become a very popular beverage among:

runners

cyclists

South American footballers

endurance athletes

Guarana and Green Tea: Natural Stimulation and Concentration

Alongside yerba mate, other ingredients used in functional infusions show interesting effects.

Guarana

The

Guarana

is known for its natural caffeine content and the presence of tannins that modulate its release.

This means that the energetic effect tends to be:

more gradual

more long-lasting

with less risk of energy spikes and crashes.

Green Tea

The

Green Tea

is rich in catechins, particularly EGCG, one of the most powerful natural antioxidants.

Numerous studies show that green tea can:

improve metabolic efficiency

reduce oxidative stress

support muscle recovery.

Antioxidants and Muscle Recovery

During intense running or cycling workouts, there is an increase in the production of free radicals.

A proper intake of natural antioxidants can contribute to:

reducing inflammation

improving recovery

supporting physiological adaptation to training.

Ingredients such as:

hibiscus

blueberry

citrus fruits

are rich in flavonoids and vitamin C, important micronutrients for endurance athletes.

Functional Infusions vs. Energy Drinks

Many athletes are progressively replacing energy drinks with more natural beverages.

Traditional energy drinks often contain:

high amounts of sugar

synthetic caffeine

artificial additives

Functional infusions, on the other hand, can offer:

natural caffeine

zero added sugars

high polyphenol content.

Functional Infusions in an Athlete's Routine

A functional infusion can be used at various times of the athletic day.

Before training

To support energy and concentration.

During the day

As a natural alternative to coffee.

After training

To promote hydration and recovery thanks to antioxidants.

The Role of Functional Infusions in Modern Sports Nutrition

Modern sports nutrition is increasingly moving towards an approach defined as “clean performance”: improving performance through natural and functional foods.

In this context, infusions based on yerba mate, green tea, and botanicals rich in polyphenols represent an interesting solution for those who practice endurance sports.

Among the infusions designed specifically for this type of use, there are also specific blends such as Endurance Matè, a combination of:

yerba mate

sencha green tea

guarana

hibiscus

orange peel

blueberry

ingredients traditionally associated with natural energy, hydration, and antioxidant support.

Conclusion

In endurance sports like running and cycling, performance depends not only on training but also on the quality of hydration and the beverages consumed throughout the day.

Functional infusions rich in polyphenols, natural caffeine, and bioactive plant compounds represent one of the most interesting solutions in modern sports nutrition.

They do not replace a balanced diet or a structured training program, but they can become a valuable ally for an athlete's energy, recovery, and overall well-being.

And it is precisely for this reason that more and more runners, cyclists, and endurance athletes are rediscovering the value of infusions in their daily routine.
