1 - 23 . (canceled) 
     
     
         24 . A floor for use in at least one of: gymnastics or fitness sector, the floor comprising:
 a plurality of floor elements which are connected to each other and which are formed from an elastic polyurethane integral foam,   wherein at least one connecting means to connect a floor element to another floor element is provided on at least one outer edge,   wherein the floor elements have a pore-free surface, and   wherein edges of adjacent floor elements contact each other in an edgeless manner and are bonded to each other with glue.   
     
     
         25 . The floor according to  claim 24 , wherein a porous structure is formed inside the floor elements. 
     
     
         26 . The floor according to  claim 24 , wherein the floor elements have a single elastic layer which consists of polyurethane integral foam. 
     
     
         27 . The floor according to  claim 24 , wherein the floor elements have a Shore A hardness in a range from 20 to 50. 
     
     
         28 . The floor according to  claim 24 , wherein the floor elements have a Shore A hardness in a range from 20 to 30. 
     
     
         29 . The floor according to  claim 24 , wherein the floor elements have a density in a range from 0.3 to 0.5 g/cm 3 . 
     
     
         30 . The floor according to  claim 24 , wherein the floor elements have a thickness in a range from 5 to 20 mm. 
     
     
         31 . The floor according to  claim 24 , wherein a lower side of the floor elements has a structured surface. 
     
     
         32 . The floor according to  claim 24 , wherein an upper side of the floor elements has a structured surface. 
     
     
         33 . The floor according to  claim 24 , wherein an upper side of the floor elements is at least partially imprinted. 
     
     
         34 . The floor according to  claim 24 , wherein the floor elements have at least one of: a rectangular or a square shape. 
     
     
         35 . The floor according to  claim 24 , wherein the floor elements are compression-moulded. 
     
     
         36 . The floor according to  claim 24 , wherein at least two adjacent floor elements are bonded with glue on a lower side of the floor elements with at least one tape or at least one batten, and
 wherein the at least one tape or the at least one batten overlaps at least one of: directly adjacent edges, edges lying directly opposite each other, or edges contacting each other along their extension, of the floor elements.   
     
     
         37 . The floor according to  claim 24 , wherein the floor elements are formed from a permanently elastic polyurethane integral foam. 
     
     
         38 . The floor according to  claim 24 , wherein at least one connecting means to connect the floor element to another floor element of the same kind is provided on at least one outer edge. 
     
     
         39 . The floor according to  claim 24 , wherein an outer shell of the floor elements has a thickness of 1 to 2 mm. 
     
     
         40 . The floor according to  claim 24 , wherein a lower side of the floor elements has a structured surface having at least one of: pimples or grooves. 
     
     
         41 . The floor according to  claim 24 , wherein an upper side of the floor elements has a structured surface having at least one of: pimples or grooves. 
     
     
         42 . A method of using the floor according to  claim 24  for at least one of: fitness, sports, gymnastics, wellness, or yoga purposes.
