The invention claimed is: 1. A crosscountry ski (1), wherein the lower face (3) of which is curved to form a wax zone (2) positioned substantially in the region lying below the user's boot, wherein at least one longitudinal recess (10) is provided extending down through the upper face (11) and along the length of the ski, and wherein the at least one longitudinal recess (10) holds a rigid longitudinal bar (12, 13) extending from the rear of the wax zone (2) to the front of said zone, with a first end (17) of the bar (12, 13) abutting (4) on an element (16) which is fixed relative to the ski, while complementary means (20) interacting with a second end (18) of the bar (12, 13) are provided in order to adjustably compress said bar (12, 13) wherein the first end and the second end of the bar is respectively fixed to the ski through the element (16) and the complementary means, and wherein the bar is constrained from deforming by walls of the at least one longitudinal recess. 2. The crosscountry ski as claimed in claim 1, wherein the fixed element (102) is used to support a component (105) of the binding for fastening the boot on the ski. 3. The crosscountry ski as claimed in claim 2, wherein the fixed element (102) or the complementary means (103) are designed as a slideway for longitudinally adjusting the position of the component (105, 110) of the binding for fastening the boot on the ski. 4. The crosscountry ski as claimed in claim 1, wherein the complementary means (103) are used to support a component (110) of the binding for fastening the boot on the ski. 5. The crosscountry ski as claimed in claim 4, wherein the fixed element (102) or the complementary means (103) are designed as a slideway for longitudinally adjusting the position of the component (105, 110) of the binding for fastening the boot on the ski. 6. The crosscountry ski as claimed in claim 1, wherein a component (121) of the binding for fastening the boot on the ski can slide on the longitudinal bar (13). 7. The crosscountry ski as claimed in claim 1, wherein the ski has two of said at least one longitudinal recesses is two each holding said longitudinal bar. 8. The crosscountry ski as claimed in claim 7, wherein the complementary means (25-31) for compressing said bars act jointly on the two bars (12, 13). 9. The crosscountry ski as claimed in claim 7, wherein the complementary means for compressing said bars each have an element (23) which is screwed parallel to the bars (12, 13) and interacts with the respective end of the bars. 10. The crosscountry ski as claimed in claim 7, wherein the complementary means for compressing said bars have an articulated linkage (40, 41; 50, 51) the free ends (44, 45; 43-54) of which interact with the ends (18) of said bars. 11. The crosscountry ski as claimed in claim 7, wherein the complementary means for pressing said bars have an eccentric cam (60) interacting with the ends of said bars. 12. The crosscountry ski as claimed in claim 7, wherein the complementary means for compressing said bars have sloping faces (84) with a slope not perpendicular to the direction of said bars, which interact with a complementary surface (81) integral with said bars. 13. The crosscountry ski as claimed in claim 7, wherein the complementary means for compressing said bars have a set of wedges (93) with different sizes, one of which is interposed between a fixed point of the ski and the ends of said bars. 14. The crosscountry ski as claimed in claim 7, wherein it has a boot binding plate (15) covering said bars (12, 13). 15. The crosscountry ski as claimed in claim 14, wherein said plate has a protruding region (19) under its lower face, which comes in contact with the upper face of the board between said bars (12, 13). 16. The crosscountry ski as claimed in claim 1, wherein the longitudinal bar is spaced apart from the walls of the at least one longitudinal recess. 17. The crosscountry ski as claimed in claim 1, wherein the at least one longitudinal recess has a cross-section and depth substantially corresponding to half the thickness of the longitudinal bar. 18. The crosscountry ski as claimed in claim 1, wherein the at least one longitudinal recess (10) is formed as a unit with and in the ski. 19. The crosscountry ski as claimed in claim 1, wherein cross-sections through the at least one longitudinal recess and the bar are respectively concave and circular. 20. A crosscountry ski (1), the lower face (3) of which is curved to form a wax zone (2) positioned substantially in the region lying below the user's boot, wherein its upper face (11) has recesses (10), and wherein each of the recesses (10) holds a rigid longitudinal bar (12, 13) extending from the rear of the wax zone (2) to the front of said zone, with a first end (17) of each bar (12, 13) abutting (4) on an element (16) which is fixed relative to the ski, while complementary means (20) interacting with a second end (18) of each bar (12, 13) are provided in order to adjustably compress said bars (12, 13), wherein it has a boot binding plate (15) covering said bars (12, 13) , and wherein said plate has a protruding region (19) under its lower face, which comes in contact with the upper face of the board between said bars (12, 13).
