Umberto Boccioni’s Unique Forms of Continuity in Space (The Strider), 1913, displays clothing whipping around and behind the body. Compressed and manipulated by the wind (as if the man were walking into a hurricane), the fabric is reduced into a pattern of arcs and triangles suggesting vectors of wind currents. In areas where the fabric wraps tightly around the thighs or chest, muscle mass may be seen. This is a representation of an athlete.  It is a dynamic and aggressive representation.

 

When analyzing a figure to determine whether it is an athlete or hero, first analyze the anatomy, proportion, and mass, before drawing your conclusion. Body language, facial expression, and the inclusion of diagonals are necessary aspects of the representation of muscles and their movement.
