Fitness: What is sweat reveal about our health and performance

Welding Sensor helps in sports and cardiovascular detects problems

Whether it’s during physical exertion, extreme heat, excitement or Stress – Welding is a constant, if not always a welcome companion of the people. The body fluid fulfils vital tasks. It regulates body temperature, protects against Overheating and maintains the acid mantle of the skin. In addition, with the sweat toxins are transported out of the body. Recently, a new welding was introduced to the sensor, the body fluid important information to be read, and so for sports and health, a large contribution can.

A research team at the Brandenburg Technical University Cottbus-Senftenberg, developed a textile-based Sensor that reads in real time the important information from the welding. To be more precise: The Sensor measures the so-called Laktalwert in sweat. This value gives information on the individual metabolic situation and indicates when the muscle activity threatens to wane. This is not only for sports, but for people with heart disease is of crucial importance.

What is lactate?

Through breathing we take in oxygen to us. During intense stress, an increased amount of it is needed. The available oxygen is not sufficient to cover the energy needs of the muscles, makes the body the metabolic product lactate, which is an acid has a favourable effect. Lactate is transported via the sweat from the body and can thus, by appropriate Sensors to be detected.

What is the lactate values are normal?

“Anyone who has ever run a stadium round as quickly as possible, realizes that the movements work and the cramps set,” explains research leader Professor Dr. Sven Michel in a press release. The Laktaktwert spent between 12 and 20 mmol per Liter of blood. This was ten times as high as the normal lactate level of an adult, the sun is usually below 1.8 mmol per Liter of blood, explains the expert.

What is the lactate value mean about the body?

The lactate value is too high, this is a sign that the muscle activities of the people dwindle. “Is the individual maximum lactate value is known, can training effects be precisely set-out,” explains research leader Professor Dr. Sven Michel in a press release. According to the research team, the Sensor can help specifically with the fat burning and in improving the muscle performance, as it allows for conditioning of the buffer capacity of the metabolism.

Also for heart patients, the Sensor makes a contribution

The sweat Sensor is not only used for sports activities. Also people with heart disease can benefit from him. Because in the case of certain heart similar values are disorders of lactate detected, which arise in healthy people only under physical effort. “You can imagine how stressful daily life in these cases must be,” said Professor Michel.

The Sensor should be in about two years

The project is funded by the German Federal Ministry for economic Affairs and energy. Together with the Institute for textile machinery and high performance material technology of the Technical University Dresden the research team wants to develop within the next two years, appropriate textiles, which include the lactate-Sensor.
