摘要：Objectives.To describe acceleration capacity in relation to performance (time over a 30 m sprint), maximum speed and muscle strength (jumping ability) and power (half-squat) in 4 women athletes specialising in sprint events at the national level.Methods.There were two days of testing (track and laboratory).We evaluated acceleration ability (instantaneous speed at 1, 2 and 3 s (vi1, vi2 i vi3)), initial acceleration (ainicial), 30 m sprint time (performance), maximum speed (vmax), jumping ability (SJ, CMJ, LJ bw and RJ 5s) and maximum average power (Pm max) in a half-squat.Results.Significant correlations were found between performance (t30m) and vmax (r=-0.980; P<0.01), acceleration ability (instantaneous speed) and t30m (r=-0.954; P<0.05) and vmax (r=0.992 and 0.979; P<0.01 and 0.05), elastic force (CMJ) and t30m (r=-0.983; P<0.05) and maximum relative dynamic strength and ainitial (r=0.980; P<0.01).Conclusions.The main finding of this study is that vmax was the major determinant of t30m.Also acceleration ability, especially vi2, and CMJ had a great influence on t30m and vmax.
