Abstract

The study investigated relationships between backstroke sprint swimming performance and variables extracted from load-velocity profiles. Thirteen male swimmers performed 50 m backstroke and semi-tethered swimming with three progressive external loads. From 50 m backstroke, race time (T_50m) swimming velocity (v_50m), stroke length and frequency were obtained. From semi-tethered swimming, maximum load (L₀) and velocity (v₀), slope and L₀ normalized to body mass (rL₀) were computed. Large to very large significant relationships were found between v_50m and all variables derived from the load-velocity profiling. Similar relationships were found between T_50m and v₀, L₀ and slope, but not with rL₀ (r = -0.530, p = 0.062). These findings indicate that load-velocity profiling is a practical method to predict and assess sprint backstroke performance and swimming velocity, and to assess propulsive force production and velocity capabilities related to backstroke sprint performance.
