A ski including a structural unit, gliding structure, as well as a decorative and protective structure. The structural unit includes at least one lower reinforcement, at least one upper reinforcement, and an intermediate structure, or core, positioned between the upper reinforcement and the lower reinforcement. The ski has a longitudinally extending cambered shape such that, when the gliding structure is positioned on a flat surface, the ski rests on a shovel contact point and a tail contact point. The ski further includes a tension structure that exerts a tension force between a first anchoring, positioned longitudinally beyond the shovel contact zone, and a second anchoring, positioned on rearward of the shovel contact zone. The tension structure is positioned for most of its length beneath the decorative and protective structure, such tension structure being positioned for most of its length above the neutral axis of the ski, such as above the upper reinforcement. The tension structure further includes a tensioning device that makes it possible to position the second anchoring in at least two positions separated longitudinally from one another by a distance between 0.5 mm and 10.0 mm, or between 1.0 mm and 7.0 mm. The tension structure includes a metal blade. The decorative and protective structure can include a window across which the blade can project. A filler can be positioned between the decorative and protective structure and the upper reinforcement, and a tunnel is arranged in the filler in order to receive the blade.
