Nutrition during effort (Intra-training)

Justification threshold (Efforts longer than 60 minutes)

Incorporating energy substrates exogenously while executing body movement is not a universal rule for any discipline.

Metabolic physiology demonstrates that internal muscle glycogen stores have the absolute capacity to finance vigorous sessions that do not exceed the sixty-minute barrier.

During relatively short workouts, ingesting caloric potions lacks any pragmatic justification, since the human machinery has not critically depleted its reserves.

However, when the aerobic odyssey crosses this hourly boundary, continuous supply becomes a non-negotiable clinical obligation to avoid crippling hypoglycemia and a drastic collapse of athletic intensity.

Sources of rapid assimilation (gels, gummies, drinks)

The logistics of intra-workout nutrition require tools that offer zero mechanical stomach work.

Attempting to chew and process solid foods in the heat of competition forces the body to divert blood to the intestinal walls, dramatically damaging the active musculature.

As a high-tech solution, the market offers ultra-processed substrates such as viscous gels, liquid isotonic solutions and pure dextrose candies.

These ergonomic formats melt quickly on the mucous membranes, guaranteeing an almost immediate transfusion of fuel directly to the brain and muscle, without triggering the slightest hint of gastric discomfort.

Hourly dosage of carbohydrates and electrolytes

The volume of this energy rescue must be mathematically orchestrated so as not to exceed the body's maximum oxidation rate.

International guidelines suggest a base range of thirty to sixty grams of simple carbohydrates per hour of strenuous activity for conventional endurance events.

However, in massively strenuous competitions, such as ocean swims or mountain marathons of inhuman duration, this protocol necessarily scales up to ninety to one hundred and twenty grams per hour.

This aggressive intake must always be accompanied by mineralized fluids to replenish the colossal sodium leakage, promoting an absolute water-electrolyte balance.
