The ability to reach a high running velocity over a short distance is essential to a high playing performance in team games. The aim of this study was to determine the relationship between running time over a 10-meter section of a 30-meter sprint along a straight line and changes in the angle and angular velocity that were observed in the ankle, knee, and hip joints. The possible presence may help to optimize motion efficiency during acceleration sprint phase. Eighteen girls involved in team sports were examined in the study. The Fusion Smart Speed System was employed for running time measurements. The kinematic data were recorded using the Noraxon MyoMotion system. Statistically significant relationships were found between running time over a 10-meter section and the kinematic variables of hip and ankle joints. An excessively large flexion in hip joints might have an unfavorable effect on running time during the acceleration phase. Furthermore, in order to minimize running time during the acceleration phase, stride should be maintained along a line (a straight line) rather than from side to side. It is also necessary to ensure an adequate range of motion in the hip and ankle joints with respect to the sagittal axis.

Purpose: Low-Dye taping is a useful technique for preventing foot injuries. However, the use of inextensible tape may lead to a decline in movement performance as a result of limited foot joint mobility and a change in vertical stiffness due to the passive stiffening of the tarsus and metatarsus. Therefore, the aim of the present study was to determine the effect of low-Dye taping on sport movement performance observed during a hopping task. Methods: The study was carried out on a group of 11 male handball players. The Myotest accelerometer was used to evaluate the effect of low-Dye taping on jumping height, ground contact time and vertical stiffness during the hopping test. Each study participant performed four series of 5 hops (hopping test): two series before low-Dye taping and two after. Results: No statistically significant differences were found between the values recorded before and after low-Dye taping for the variables that describe the hopping task: mean jump height, mean ground contact time and mean vertical stiffness. Conclusions: Low-Dye taping can be successfully used in handball players since it has a preventive effect that reduces the risk of injury to the foot and does not influence vertical stiffness or jump height to a significant extent.

Abstract. The aim of the study was to evaluate the threshold of muscle pain sensitivity at the posterior line of the futsal player's lower extremity muscles under the influence of the stimulation of the foot arch with a nonelastic tape application. The study included 25 futsal players representing university club AZS AWF Wroclaw. During the experiment, a nonelastic tape was applied on the plantar foot surface, basing on the standards of low-Dye taping.The test program consisted of a 3-day cycle, during which the pressure pain threshold (PPT) was measured: 1) before application of the tape, 2) 24 hours and 3) 72 hours after application. The PPT was measured using the Somedic Algometer type 2. Analysis of the results was performed using analysis of variance for repeated measures and post hoc Bonferroni's test. Long-term stimulation of plantar surface significantly affects the increase in the PPT in the lower extremity posterior line muscles. In motor control trainings, especially in match-starter terms, new physiotherapeutic measures and therapeutic techniques should be used.
