The 2015 World Ice and Snow Sailing Championship will be held in Fond du Lac, Wisconsin, USA, between February 9th-14th.

The World Ice and Snow Sailing Association (WISSA) is taking the competition to North America. Fond du Lac is located on the shores of Lake Winnebago, one of the largest lakes in the USA.

The spot offers the ideal blend of ice and snow conditions for daytime races. The contest will crown the best sailors in three classes: Sleds (handheld windsurfing sails), Kites (skis and snowboards) and Wings (wings, kite wings and skate sails).


Windsurfing: how often do you feel Delayed Onset Muscle Soreness? | Photo: PWA/Carter

Pain and stiffness felt in muscles between 24 and 72 hours after windsurfing is common and is likely to limit your performance when windsurfing. But why do many sailors experience muscle soreness and stiffness after sailing and some don't?

Henrik Beyer, health promoter and author of "Health & Fitness for Windsurfing," gives us an insight in what research has to say about muscle soreness and what to do about it.

This phenomenon is called Delayed Onset Muscle Soreness (DOMS), and it is not entirely understood. Research has claimed that DOMS is a result of structural damage and an inflammatory reaction in the muscle and is caused by the lengthening (eccentric) contractions of the muscle. Some may experience DOMS after each strenuous workout or sailing session, and some less frequent.
