       3 . The snowboard of  claim 1  wherein the hollow chamber is formed by a region of the running surface layer and a region of a laminate applied to the core opposite the running surface layer.  
   
   
       4 . The snowboard of  claim 1  wherein the hollow chamber is in flow connection with a valve.  
   
   
       5 . The snowboard of  claim 2  wherein the hollow chamber is in flow connection with a valve.  
   
   
       6 . The snowboard of  claim 3  wherein the hollow chamber is in flow connection with a valve.  
   
   
       7 . The snowboard according to  claim 1  wherein the at least one hollow chamber is between the core and the running surface layer.  
   
   
       8 . The snowboard according to  claim 5  wherein the valve is on a top side of the snowboard facing away from the running surface layer.  
   
   
       9 . The snowboard according to  claim 6  wherein the valve is on a top side of the snowboard facing away from the running surface layer.  
   
   
       10 . The snowboard of  claim 1  wherein there is only one hollow chamber, and this hollow chamber extends in the longitudinal direction of the snowboard.  
   
   
       11 . The snowboard of  claim 2  wherein there is only one hollow chamber, and this hollow chamber extends in the longitudinal direction of the snowboard.  
   
   
       12 . The snowboard of  claim 3  wherein there is only one hollow chamber, and this hollow chamber extends in the longitudinal direction of the snowboard.  
   
   
       13 . The snowboard of  claim 4  wherein there is only one hollow chamber, and this hollow chamber extends in the longitudinal direction of the snowboard.  
   
   
       14 . The snowboard according to  claim 1  wherein said at least one hollow chamber comprises at least two hollow chambers which extend parallel to each other and in a longitudinal direction of the snowboard.  
   
   
       15 . The snowboard according to  claim 2  wherein said at least one hollow chamber comprises at least two hollow chambers which extend parallel to each other and in a longitudinal direction of the snowboard.  
   
   
       16 . The snowboard according to  claim 3  wherein said at least one hollow chamber comprises at least two hollow chambers which extend parallel to each other and in a longitudinal direction of the snowboard.  
   
   
       17 . The snowboard according to  claim 4  wherein said at least one hollow chamber comprises at least two hollow chambers which extend parallel to each other and in a longitudinal direction of the snowboard.  
   
   
       18 . The snowboard according to  claim 15  wherein a separate valve is assigned to each hollow chamber.  
   
   
       19 . The snowboard according to  claim 15  wherein at least two of said at least two hollow chambers are connected to each other so that they can carry a flow and can be filled in common by a single valve.  
   
   
       20 . The snowboard according to  claim 1  wherein the at least one hollow chamber comprises a hollow nose chamber arranged in a nose region of the snowboard.  
   
   
       21 . The snowboard according to  claim 2  wherein the at least one hollow chamber comprises a hollow nose chamber arranged in a nose region of the snowboard.  
   
   
       22 . The snowboard according to  claim 3  wherein the at least one hollow chamber comprises a hollow nose chamber arranged in a nose region of the snowboard.  
   
   
       23 . The snowboard according to  claim 4  wherein the at least one hollow chamber comprises a hollow nose chamber arranged in a nose region of the snowboard.
