Understanding regeneration, improving performance

The secret to sporting success lies in rest

Many athletes invest a lot of time and energy in their training. But whether training stimuli actually lead to improved performance is not decided during the workout, but afterwards. Regeneration is the process in which the body recovers, adapts and comes back stronger. Those who pay too little attention to it are wasting potential – regardless of their performance level. With the aim of boosting performance naturally without doping and regenerating more effectively, BioRelax's Kleinsche Fields are becoming a real secret recipe for amateur and professional athletes!

Recovery phases after sport 
more than just taking a break

Regeneration is often equated with time off from training. But simply not training does not mean true recovery. Those who return to their daily work routine immediately after exercise often remain under stress – both physically and mentally. 

Regeneration is more about specific processes that help the body deal with stress. It needs conditions where muscles, metabolism, and the nervous system can recover. Only then does a break turn into real regeneration.

If you want to improve your performance,  
need real regeneration

Training provides targeted stimuli that initially put strain on the body. Only in the subsequent regeneration phase can the organism process these stimuli, renew tissue and adapt. This adaptation process forms the basis for improving performance. If regeneration does not occur or is insufficient, training stimuli are wasted or lead to overload and performance stagnation in the long term. If you want to make progress, you must therefore understand regeneration as an integral part of training.

What professionals do differently
Make targeted use of training-free time

Competitive athletes know that recovery does not happen by chance. It is an integral part of training – just as planned as exertion and intensity. 

Professionals therefore make a clear distinction between passive recovery, such as sleep and rest, and active recovery. The latter involves targeted measures to support the recovery process. 

While passive recovery primarily serves the purpose of basic restoration, active recovery focuses on the areas where stress has actually occurred. It helps to reduce muscle tone, promote blood circulation and support metabolic processes. The goal: faster and better recovery.

how professional athlete Thomas Frühwirth regenerates
 

Thomas Frühwirth lives and breathes sport – and has done so for decades. Known as "TiggerTom", the para-athlete is still at the top of his game at 44 and successfully competes with significantly younger athletes. His goal: to consistently maximise his own performance and continuously develop himself further.

Regeneration is a crucial factor for him. Thomas Frühwirth has been intensively involved with the topic for more than 20 years and has tried out a wide variety of approaches. He sums up his most important insight clearly: "Sleep is the most important regeneration tool – alongside nutrition."  
Accordingly, the exceptional athlete attaches great importance to regular and sufficient sleep. But he does not rely on that alone. To specifically support his recovery, Thomas Frühwirth also sleeps on a BioRelax Mattress topper every night.  

Especially after intense competitions, I have found that my muscles recover noticeably better overnight and are back to full strength the next day.

After training and especially before going to bed, he applies BioRelax pads – with the original Kleinsche Felder technology – to the stressed muscles. 

The big advantage for me is the targeted application: the pads work exactly where the strain occurs and where the body needs support.

His experience with the gentle magnetic fields: 

After a short time, I feel a pleasant warming sensation and improved blood circulation exactly where the muscles are under heavy strain. This allows the muscles to regenerate much better overnight, so that muscle tone is noticeably reduced in the morning and I am fit for action again.

He particularly emphasises the point about improved blood circulation. This is an important aspect of regeneration. A well-supplied muscle can not only remove metabolic waste products more effectively overnight, it also receives more nutrients – ideal conditions for genuine recovery. Thanks to his well-established regeneration routine, the professional athlete can quickly return to peak performance even after intensive training or competitions.

About

Thomas Frühwirth is one of Austria's most prominent para-athletes. Born in Styria in 1981, he has never stopped redefining his limits since becoming paraplegic as a result of a motorbike accident in 2004 – on the contrary: he continues to live out his passion for sporting challenges with unbroken intensity to this day. 

From 2008 onwards, Frühwirth first made a name for himself in para-triathlon, where he set standards as a world champion, record holder and Ironman finisher, among other things. He then devoted himself increasingly to para-cycling and is now one of the most successful handbike athletes in the world. 

Known by the nickname "TiggerTom", he embodies a unique combination of determination, joie de vivre and consistency. At the Paralympics in Rio de Janeiro in 2016, Tokyo in 2020 and Paris in 2024, he won several silver medals in the individual time trial and road race – often against strong international competition. His successes at World and European Championships ( ) and titles at the Para-Cycling World Cup underline his consistency. At the World Championships alone, he has collected more than a dozen medals over the years, including several gold titles, most recently in the individual time trial in Zurich. 

At an incredible 44 years of age, Tigger Tom is living proof that peak performance is not solely a factor of youth. It is the result of experience, discipline and a conscious approach to stress and recovery. Regeneration in particular plays a central role for him in training and competition. 

The exceptional athlete reveals his personal recovery routine in an interview.

"BioRelax products have become an integral part of my recovery routine. Whether training, competing, or traveling, Kleinsche Fields are always with me."

how professional athlete Thomas Frühwirth regenerates
 

Top performance requires more than just training. The decisive factor is how specifically regeneration is planned and supported. BioRelax therefore pursues a systemic approach: the products are designed to accompany both active and passive regeneration phases – whether after training, competition or simply in everyday life.

With our BioRelax products, we deliberately focus on gentle, natural support that does not require electricity and can be used flexibly. The application is uncomplicated, suitable for everyday use and can be easily combined with existing training, therapy or regeneration routines.


One system – flexible use

With our mattress topper, pads and seat cover, we offer several products based on Kleinsche Fields technology that support your recovery in different phases. They can be combined depending on the situation and support regeneration during sleep, after exercise or on the go.

The sleeping mat accompanies the nightly rest phase over several hours and supports regeneration as a long-term application. The pads enable selective, targeted support after training or competition – exactly where the strain has occurred. In addition, the seat cover can also accompany regeneration phases on the go and make use of times that would otherwise remain unused.

This creates a flexible system that can be adapted to the scope of training, type of sport and individual requirements.

BioRelax Mattress Topper – 
for the most important phase of regeneration  

Sleep is the basis of all regeneration. At the same time, it is also the most sensitive phase, which should not be disturbed. Our goal was therefore clear: BioRelax products should support sleep and accompany the regeneration processes that take place during this time. That is why we have developed the BioRelax Mattress Topper to blend inconspicuously into the night-time rest phase. No electricity, no charging and no active operation required. Once placed in bed, it supports regeneration in the background. Sleep remains as it should be – calm, natural and undisturbed.

BioRelax Pads – 
targeted where stress arises

Our tip: The BioRelax Seat Cover 

Athletes spend a lot of time travelling – in cars, buses or aeroplanes. These phases are part of everyday sporting life, but often remain unused. Yet it is precisely the time between training, competition and everyday life that offers valuable opportunities to consciously support regeneration. The BioRelax seat cover can be used flexibly and supports regeneration while sitting – without any additional effort. This allows time to be used wisely while on the move and integrates regeneration where it is often neglected.

BioRelax – popular with professional and amateur athletes

Every body reacts differently to stress. That's why many athletes rely on a regeneration system that is flexible and leaves room for individual routines. BioRelax products enable this flexibility.

They can be used over a large area or selectively – as a sleeping mat or seat cover for several hours or as pads directly on stressed muscle areas. Many athletes deliberately combine sleeping mats and pads to support their regeneration overnight and specifically after training.

The system can be integrated into existing routines without preparation – even on the go. It is precisely this simplicity that makes the difference and is increasingly convincing amateur and professional athletes alike.

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.
