Isokinetic strength and power of female field hockey players

Isokinetic strength and power of female field hockey players

Many performances in sports including hockey players need strength and power. The purpose of this study was to investigate the strength and power of female field hockey players. Subjects were 11 female sub-elite field hockey players. Data was obtained from isokinetic strength and power test using a Cybex 340 isokinetic dynamometer. The protocol of the Cybex test involved the measurement of isokinetic strength as peak torque in a slow velocity movement (60°·sec−1), and isokinetic power as peak torque in a medium velocity movement (180°·sec−1), during knee flexion and extension of both right and left legs. Data were analyzed using mean and standard deviation (X±SD).

The results of this study found that the mean hamstring strength were 88.2±10.6 N·m and 1.4±0.2 N·m·kg−1 (left); and 88.5±13.9 N·m and 1.4±0.2 N·m·kg−1 (right). Mean quadriceps strength were 152.9±27.0 N·m and 2.4±0.3 N·m·kg−1 (left); 152.6±19.2 N·m and 2.4±0.2 N·m·kg−1 (right). Mean hamstring power were 58.1±13.8 N·m and 0.9±0.2 N·m·kg−1 (left) and 61.3±14.4 N·m and 1.0±0.2 N·m·kg−1 (right). Mean quadriceps power were 100.2±12.5 N·m and 1.6±0.2 N·m·kg−1 (left); 94.9±13.7 N·m and 1.5±0.2 N·m·kg−1 (right). The conclusion of this study was stated that hamstring strength and quadriceps power of the players were lower than elite hockey players, but hamstring power and quadriceps strength were greater than healthy women.
