Sports Hydration Drink - Guires Food Research Lab

During intense physical activity, the body loses water and electrolytes through sweat, while carbohydrates are oxidized by the working muscles. Consuming a combination of water, sugar, and salt during exercise helps prevent the adverse effects of dehydration (hypohydration) and provides essential glucose to the muscles, brain, and other tissues, supporting overall carbohydrate oxidation. Extensive peer-reviewed research supports the advantages of consuming carbohydrate-electrolyte solutions during exercise, and beverage manufacturers use this research to develop and validate the benefits of their products.

Sports Hydration Drink: Guidelines for Carbohydrate-Electrolyte Solutions

Share It:

EFSA Guidelines for Carbohydrate-Electrolyte Solutions

The EFSA has set forth specific criteria for carbohydrate-electrolyte solutions, particularly regarding their carbohydrate concentration, osmolarity, and electrolyte content, to qualify them as beneficial for both physical performance and recovery from the physiological stress of exercise. Here are the key points:

Osmolarity:
EFSA suggests that the osmolarity of sports drinks should generally be close to that of the body’s own fluids (isotonic), which range from 280 to 295 mOsmol/kg. Solutions can be slightly hypo- (less concentrated than blood) or hypertonic (more concentrated), depending on the intended use (quick hydration vs. energy supply).
Sodium Content: Sodium is crucial not just for osmotic balance but also for stimulating thirst and replacing salts lost through sweat. EFSA recommends a sodium concentration range typically around 460-1150 mg/L for sports drinks to enhance hydration and stimulate carbohydrate uptake.

The following Table shows the effects and applications of replacement drinks as established by EFSA’s scientific opinion.

	Types of Beverage Replenishment	Conditions of Use	Ergogenic Effects
EFSA Regulation (EC) No 432/2012 [33].	Carbohydrate electrolyte solutions	a. Between 80 and 350 kcal/L of carbohydrate. b. At least 75% of energy must be derived from carbohydrates. c. Sodium between 20 mmol/L (460 mg/L) and 50 mmol/L (1150 mg/L). d. Osmolarity between 200 and 330 mOsm/kg water.	Maintain the level of endurance in exercises that require prolonged endurance. Improve water absorption during physical exercise.
EFSA Regulation (EC) No 686/2021 [34].	Carbohydrate solutions	e.Between 30 and 90 g carbohydrate/hour, where the carbohydrate in question is glucose, sucrose, fructose, or maltodextrin, under these conditions: – Fructose (from fructose or sucrose) should not account for more than one third of the total carbohydrate, and – Glucose (from glucose, sucrose or maltodextrin) should not exceed 60 g/h. f. The consumer should be informed that only trained adults performing high-intensity (at least 65% of VO2max) and long-duration (at least 60 min) physical exercise and of long duration (at least 60 min) will obtain the beneficial effect.	Improved physical performance during high intensity and long duration physical exercise in trained adults.

The characteristics of sports drinks consumed during exercise, including their sugar content, sodium levels, and specific formulations tailored for different phases of physical activity, are summarized in the following table.

Characteristic	Minimum	Maximum
Sugars (%)	6%	9%
Type of Sugars	Mix of rapid absorption sugars (glucose or maltodextrin) and sugars with slow absorption rate (fructose) in a 3:1 ratio.	[Fructose] > 33%
Minerals (g/L) Na	0.46 g/L	1.20 g/L
Osmolarity (mOsm/L)	200	330
Volume (mL/hour of exercise)	500 mL	1000 mL
Temperature (°C)	10°C	15°C
Frequency (min in the exercise)	15 min	30 min

Particular Characteristics:

In extreme temperatures (above 30°C), it is recommended to add ice cubes to the drink.
The drink should be palatable.
For high hydration needs, it is advisable to reduce sugar concentration to 4-6% and increase salt content (0.7 to 1 g/L) to prevent hyponatremia.

The characteristics of sports drinks tailored for different phases of training—before, during, and after exercise—are outlined in the following table. This includes variations in sugar content, sodium levels, and drink types, designed to optimize hydration and performance at each stage of physical activity.

Timing	Drink Type	Sugar Content	Sodium (Na⁺) Content
Before	Isotonic or slightly hypotonic	4-6% sugars	0.5-0.7 g Na⁺/L
During	Isotonic	6-9% sugars	0.5-0.7 g Na⁺/L
			0.7-1.2 g Na⁺/L (if exercise lasts longer than 1 hour or under heat stress)
After	Hypertonic	9-10% sugars	1-1.5 g Na⁺/L

The following table presents the types of beverages and their specific applications in sports, detailing how different drinks are utilized to support athletic performance and recovery.

Food Liquid	Water Content (%) EFSA, 2010a	Characteristics/Applications
Hypotonic Drink	90-100	Contains a lower concentration of solutes per unit volume than blood, similar to water.
Isotonic Drink	90-100	Recommended for consumption before exercise. Contains simple sugars and electrolytes (sodium) that match blood osmotic pressure.
Hypertonic Drink	90-100	Recommended for use during exercise. Contains higher concentrations of solutes, sugars, and/or sodium per unit volume than blood.
Milk and Liquid Yogurt	75-90	Recommended for use after exercise. Provides high biological value protein, branched amino acids, and sugars.
Juice	90-100	Recommended for use after exercise. Contains fruit juice, nectar, or sugary juice with varying sugar concentrations (10-13%).
Energy Drinks	90-100	Recommended for use after exercise due to their liquid and carbohydrate content. Provides fluids, simple sugars, and various other nutrients, many of which lack scientific evidence or clinical trials.

The following table outlines the nutrition and health claims made by the food industry, highlighting the characteristics of specific nutrients, such as carbohydrates and proteins, and their roles in supporting muscle recovery, endurance, hydration, and performance during physical activity.

Health Claims	Characteristics (CH and Proteins)
Supports muscle recovery after exercise	– After exercise: Drink a liquid solution of carbohydrates (CH) at 1 g/kg and high biological value proteins (1/3-1/4 of total CH)
	– To aid in muscle and liver glycogen recovery and protein synthesis.
