Abstract:

Aerodynamics is considered as one of the decisive factors in elite sports competitions. By streamlining the athlete’s body configuration in fluid, aerodynamic or hydrodynamic resistance can considerably be reduced. In swimming, it is claimed that by utilising the full body swimsuit, the performance can be enhanced. However, there is not enough scientific data to support this. Moreover, it is not clear how a swimsuit can minimise drag. Therefore, the main objective of this work was to study the microscopic effect of swimsuit materials on aerodynamic behaviour under various stretched conditions of a commercially available swimsuit material. The study was conducted experimentally for a range of Reynolds numbers using a cylindrical methodology to quantify the effects of swimsuit materials on aerodynamic properties in wind tunnel environment. The microscopic analysis of swimsuit materials indicated a correlation between the aerodynamic properties and the swimsuit surface structure.
