After intensive endurance exercise – especially in the heat – the body not only loses water, but also important minerals. This can lead to reduced performance, muscle strength and recovery for hours or even days.
This clinical study investigated whether deep mineral water with moderate mineralization supports regeneration after heavy, sweat-inducing exercise better than normal drinking water.
Healthy, athletically active women completed strenuous running training at high temperatures, which specifically led to dehydration. They then drank either normal water or deep mineral water.
The result was clear: participants who drank deep mineral water recovered more quickly. Their endurance performance was restored just a few hours after exercise, while it remained limited with normal water. Muscle strength in the legs also returned to its original level more quickly.
There was also evidence that deep mineral water alleviates muscle damage and signs of fatigue. The special combination of magnesium, calcium, sulphate and trace elements appears to support cell function and blood circulation during recovery.
Conclusion: Deep mineral water can significantly accelerate regeneration after intensive endurance exercise and is therefore a useful support for people who are active in sports.
Background
Physical exertion in warm conditions leads to increased loss of fluids and minerals. Even moderate dehydration can impair endurance, muscle strength and coordination. Complete regeneration therefore requires not only water, but also a targeted replenishment of minerals that are involved in muscle work, blood circulation, energy metabolism and antioxidant protection.
Deep mineral water differs from conventional drinking water due to its naturally grown mineral and trace element composition, which results from thousands of years of geological filtration. The authors of the study investigated whether this special composition offers a measurable advantage for physical recovery.
Study design
The study was conducted as a randomized, double-blind, placebo-controlled crossover study. The participants completed two identical exercise protocols several days apart. After each exercise test, they were rehydrated with either deep mineral water or normal water, without the subjects knowing which drink they were receiving.
Among other things, the following were measured:
-
the restoration of aerobic performance,
-
leg muscle strength ,
-
Markers for muscular fatigue and
-
the course of recovery over several days.
Central results
1. faster recovery of stamina
After rehydration with deep mineral water, aerobic performance recovered significantly faster. Endurance performance was fully restored just a few hours after exercise, whereas it remained delayed with normal water.
2. improved muscle strength recovery
Leg muscle strength normalized more quickly after deep mineral water and was even higher after two days than with normal water. This indicates an improved neuromuscular recovery.
3. fewer signs of muscle fatigue
Typical signs of training-related fatigue and muscle damage were less pronounced after deep mineral water. This suggests a protective effect on muscle cells.
Possible mechanisms of action
The authors discuss several possible explanations:
-
Magnesium and calcium support muscle contraction, energy utilization and nerve conduction.
-
Sulphate and trace elements contribute to detoxification, antioxidant defense and cell stability.
-
The combination of minerals can promote plasma volume regeneration, which improves cardiac output, blood circulation and oxygen transport.
In contrast to many sports drinks, deep mineral water does not primarily work via sugar or stimulating substances, but via physiological cell and vascular mechanisms.
Significance for practice and prevention
The results show that not only the amount of fluid, but also the quality of the water is crucial for a full recovery. Deep mineral water could be particularly useful for:
-
Endurance and team athletes,
-
Training in the heat,
-
This is a sensible addition to the regeneration strategy for people with a high sweat rate.
Conclusion
Deep mineral water accelerates the recovery of endurance performance and muscle strength after severe dehydration. The effect is presumably based on the synergistic combination of minerals and trace elements that support central regeneration processes in the body.
The study underlines the importance of mineral-conscious rehydration and opens up new perspectives for sports nutrition, regeneration and prevention of physical exhaustion.
