Description
The aim of this research was to develop a path-flow analysis model to highlight the relationships between buoyancy
and prone gliding tests and some selected anthropometrical and biomechanical variables. Thirty-eight young male
swimmers (12.97 ± 1.05 years old) with several competitive levels were evaluated. It were assessed the body mass,
height, fat mass, body surface area, vertical buoyancy, prone gliding after wall push-off, stroke length, stroke frequency
and velocity after a maximal 25 [m] swim. The confirmatory model included the body mass, height, fat mass, prone
gliding test, stroke length, stroke frequency and velocity. All theoretical paths were verified except for the vertical
buoyancy test that did not present any relationship with anthropometrical and biomechanical variables nor with the
prone gliding test. The good-of-fit from the confirmatory path-flow model, assessed with the standardized root mean
square residuals (SRMR), is considered as being close to the cut-off value, but even so not suitable of the theory (SRMR
= 0.11). As a conclusion, vertical buoyancy and prone gliding tests are not the best techniques to assess the swimmer’s
hydrostatic and hydrodynamic profile, respectively.
