The German Skiing Association (DSV) and lighting expert Osram are positive about
their collaboration so far. To mobilize new energy reserves among its athletes, the
DSV has been applying the latest findings on “biologically effective light” for more
than two years now. Specially designed LED light glasses, now being presented at
the German Alpine Skiing Championships, are used to prepare for night races.

Before the start of the race, the glasses give the skiers an intensive light shower and
thus help them to be alert and focused at the right time. “In high-performance
sports, the slightest difference determines success or failure. The biologically
effective light in these glasses enables the athletes to mobilize new energy reserves
especially before night races and be more alert and focused,” says Karlheinz
Waibel, Federal Trainer for Science and Technology at the DSV.

The LED glasses, currently still a prototype, are equipped with around 20 LEDs and offer a
light intensity that is several times brighter than workplace lighting. To achieve the desired
effect, the athletes wear the glasses for about 15 minutes before the race. Light glasses
were used, for example, at the double victory of Felix Neureuther and Fritz Dopfer in the
night slalom in Madonna di Campiglio in 2014. “In addition to top-class sport, the light
glasses could also be used by airlines, for example, to reduce passengers’ jet lag by
speeding up their adjustment to the time at their destination through targeted light
simulation,” says Osram biologist Andreas Wojtysiak.

Besides the light glasses, the DSV also employs two other Osram luminaires that are used
particularly on trips to other time zones and in Nordic countries with shortened hours of
daylight.

The specially developed luminaire for athletes’ rooms is used for individual competition
preparation. It especially helps athletes begin their day in a more active and focused
manner. In the evening, the light enables them to more easily wind down and regenerate
their bodies. Athletes can thus boost their performance during the day.

The second type of luminaire was also designed with a similar goal in mind. It is used in
particular to light common areas and rooms where team meetings are held. With its high
luminous flux, it functions like a “light shower”. Used individually or in combination, both
systems help athletes reset their biological clocks even on long trips overseas or to the Far
East, for example. Targeted light enables them to adjust to the local time much more
quickly. As a result, jet lag symptoms are significantly reduced and the athletes return
much faster to a balanced sleep-wake cycle, allowing them to better achieve their normal
performance and reaction levels despite long, grueling trips.
