A new mathematical mode for studying hydrodynamic force was developed. The purpose of this study was to present a simple, inexpensive, reliable and less complicated methods. In order to verify the proposed model, 5 male recreational swimmers ranging in age from 20 to 25 years and in mass from 71 to 82 kg have been served in our study. They were requested to swim a 10-meter distance as fast as they could and three to five trials with enough rest in between. They have also been instructed to glide at end of 10m swim, by whistling, until still position. The time of 10m swim and the glided distance were measured with reasonable precision (10-2 Sec 10-2 m, respectively). One of the elite subjects was requested to perform swimming with different speeds in order to achieve different characteristic curves as model. The data collected were then used in proposed formulae in different approaches for achieving velocity, acceleration, propulsive or resistive forces of the subjects, The results obtained agree well with the results obtained by other researchers with complicated and expensive systems.
