RELATIONSHIPS AMONG SPRINT VELOCITIES, HORIZONTAL GROUND REACTION FORCE, AND ISOKINETIC TRUNK STRENGTH VARIABLES
The purpose of this study was to investigate the relationships among sprint velocities, horizontal ground reaction force, and isokinetic trunk strength variables. Voluntary 19 athletes were participated to the study [age (year)= 20.9±2.3, training age (month)= 91.3±48.2, body height (cm)= 173.1±6.5,...

| description | The purpose of this study was to investigate the relationships among sprint velocities, horizontal ground reaction force, and isokinetic trunk strength variables. Voluntary 19 athletes were participated to the study [age (year)= 20.9±2.3, training age (month)= 91.3±48.2, body height (cm)= 173.1±6.5, body weight (kg)= 64.7±8.4] from different sports including in explosive strength. Sprints (10m, 20m, 30m, and 40m) were tested on a non-motorized treadmill. Velocities (V10m, V20m, V30m, and V40m) and horizontal ground reaction forces (HGRF-10m, HGRF-20m, HGRF-30m, and HGRF-40m) of the sprints were calculated. Isokinetic trunk strength criteria (flexion-extension peak torques) at 3 different angular velocities (30o.s-1, 90o.s-1, and 120o.s-1) were tested. Pearson Correlation Coefficient was used for statistical analysis. Probability level was p≤0.05. All sprint velocities was correlated with all horizontal ground reaction forces (except the correlation between V10m and HGRF-20m) and all isokinetic trunk flexion-extension peak torques (except the correlation between V10m and isokinetic trunk flexion peak torque at 120o.s-1). Statistically highest significant correlations have been found between V40m and all horizontal ground reaction forces and also between V40m and isokinetic trunk flexion-extension peak torques (30o.s-1, 90o.s-1, and 120o.s-1). There were significant relationships of horizontal ground reaction forces with isokinetic trunk extension-flexion peak torques at 30o.s-1, 90o.s-1, and 120o.s-1. In conclusion, isokinetic trunk flexion and extension strength values are crucial for improving sprint acceleration and horizontal component of ground reaction force. |
