The Influence of Sprint Mechanical Properties on Change of Direction in Female Futsal Players

The aim of the present study was to analyze the association of the sprint force-velocity profile LHzt FV profile] variables with change of direction [COD] performance in female futsal players. Twelve female futsal players (age: 19.83 +/- 4.2 years; body height: 160.75 +/- 8.37 cm; body mass: 57.64 +/- 8.3 kg) volunteered to be evaluated in the following assessments: Hzt FV profile, 505 test, modified 505 test [M505test] and V-cut test. The Spearman's correlation coefficient [r(s)] (p < 0.05) was used to determine the relationship of the mechanical variables of the sprint (maximum power output [P-max], maximum horizontal force production [F-0] and maximum velocity [V-0]) with COD performance. V-0 showed a very large significant association with the 505 test (r(s) = -0.767; 90% CI: (-0.92 to -0.43); p < 0.01) and a large association with the V-cut test (r(s) = -0.641; 90% CI: (-0.86 to -0.21); p < 0.05), whereas P-max was strongly associated with results of the 505 test (r(s) = -0.821; 90% CI: (-0.94 to -0.55); p < 0.01) and largely associated with the V-cut test results (r(s) = -0.596; 90% CI: (-0.84 to -0.14); p < 0.05). In conclusion, maximal power and velocity output during sprinting are determinant factors to successful COD in 180 degrees and 45 degrees cuts, thus, the Hzt FV profile should be assessed in female futsal players to better understand the influence of sprint mechanical properties on COD performance and prescribe individualized training programs.
