BioRelax products in sport

The secret of your sporting advantage

The professionals show us how it’s done: nature offers the simplest solution for “higher–faster–further.” Kleinsche Fields, harnessing the power of natural magnetic fields, are becoming increasingly popular across a range of elite sports. Almost every athletic discipline demands everything from the body — muscular strength, focus, reaction speed and coordination. These are exactly the areas that Kleinsche Field technology is designed to support.In sport especially, the better the cells perform — and the more efficient the supply and removal of nutrients and waste — the more effectively the entire body functions.With the goal of boosting performance naturally, without doping, and enhancing recovery, Kleinsche Fields from BioRelax are becoming a true insider secret for both amateur and professional athletes.

Before training and competition!

Improved preparation

After the competition is before the competition. Muscles that are well supplied with blood and full of cellular energy are not only more relaxed, but also stronger and less prone to injury. BioRelax products are already well established in professional sports thanks to their regenerative potential. The muscular energy supply is crucial for performance in both training and competition — and this should be optimised during recovery phases. In the world of sport, everything revolves around improving cell performance. Do the cells have enough mitochondria? Are there DNA mutations? Are the mitochondria damaged or weakened? These factors have a major influence on physical capability.Kleinsche Fields are designed to support mitochondrial function even before physical activity, helping to prepare the body for peak performance. Athletes already use nutritional supplements, specialist diets, and various methods to optimise outcomes. We’re convinced of this: when the mitochondria work better, overall athletic performance improves — for professionals and amateurs alike.

BioRelax – for that extra edge

Increased Performance

Show everyone — your competition and your inner critic! When it’s time to perform, you’re fully focused. Every ounce of concentration is needed. In milliseconds, you must react correctly to each situation. There’s no room for mistakes. BioRelax products are designed to support your brain in delivering top mental performance. With sharp focus and sustained mental endurance, you can respond quickly and effectively — even under intense physical strain.Whether you’re in training or in the heat of competition, BioRelax gives you the edge you need in that crucial moment. Faster reaction times than your opponents can make all the difference — whether it’s about winning a race or raising the level of your personal best.What sounds like doping is actually natural. Your secret weapon: BioRelax pads and BioRelax insoles.

Faster Regeneration

After training or competition, your body needs rest and recovery. BioRelax products are designed to give your body exactly what it requires: energy for repair, healing processes, and cell renewal — so it can return to peak performance faster when it’s needed again. During this phase, effective blood circulation for nutrient delivery and waste removal is essential. Lactate and cellular waste must be cleared from the muscles, and the so-called microtraumas from physical exertion need to be repaired. Your cells are literally ready to refuel. The BioRelax sleeping mat acts as your personal“charging station”. You can also support targeted recovery by applying BioRelax pads directly to affected muscle areas. This principle doesn’t just help you bounce back in sport — it supports your performance and wellbeing in everyday life, too.

Popular with professional and amateur athletes

BioRelax products can be used as a full-body mat for sitting or sleeping, or locally as pads applied to specific areas. The combination of targeted application during the day and full-body support at night using the BioRelax sleeping mat has produced the most noticeable results.
Kleinsche Fields operate completely without electricity or batteries, and generate no electrosmog that could interfere with cellular function.

A growing number of amateur and professional athletes trust in the power of BioRelax and Kleinsche Fields — whether in the gym, on the track, or on the pitch.

"Thanks to the insoles, I was able to run through the fourth training session of the day at a relatively high pace without pain. It was amazing that the days travelling to Florida, where I had been on the road for around 32 hours, were much more bearable with the insoles; subjectively speaking, I just felt fresher."

"I have the feeling that my blood circulation is really stimulated. It was the same the first few times I lay on the sleeping mat at night. I also felt a flowing sensation. The next morning I generally have the feeling that I'm much more rested."

They can also be worn in socks, e.g. at night when sleeping.The scope of delivery "piece" always refers to a pair of insolesHow BioRelax Kleinsche Fields insoles work:
All nerve signals in the body are actually electrical signals that are transmitted through the body via the nerve pathways - to the brain and back again. The nerves can therefore also be influenced by the charges of the positive and negative poles of a permanent magnetic field.
 Klein fields are said to stimulate nerve signals in a gentle, natural way. This is because the electrical charge particles of the nerve signal move through alternating positive and negative charges.This interaction with the pole changes measurably activates the entire nervous system. The aim is to stimulate muscles that are located further away from the feet by networking the nerve pathways in the muscles of the body. Contact with BioRelax insoles can therefore measurably increase the muscle tension and performance of various muscle groups.Only 3 mm thin - can be worn discreetly in any shoeFully integrated small fields - no punctual application, but even coverageSuitable for all day use - whether in the office, during sport or on the goAntibacterial & washable - easy to clean and hygienicAvailable in many sizes - from 36 to 46, can be customisedYou can find lots more information and tips about the insoles in the Questions and Answers section below.
