Sažetak
The aims of the present study were to investigate the relationship between muscle power recorded in vertical jumps and body size, and to explore possible differences in this relationship between the concentric (CON) and stretch-shortening cycle (SSC) muscle action. Subjects were tested on two CON and two SSC vertical jumps. The relationship between muscle power (P) and body size (S) was assessed by P=a Sb where a and b were constant multiplayer and scaling exponent. The results revealed that muscle power scales to body size at a higher rate than predicted by geometric similarity (i.e., b = 0.67), while larger individuals could gain more when switching from CON to SSC muscle action. These findings could be based on a non-geometric scaling of transversal with respect to longitudinal dimensions and/or on different scaling rates of muscles and tendons.
