Effects of small-sided games on physical conditioning and performance in young soccer players.
The purpose of this study was to examine, first, the movement actions performed during two different small-sided games and, second, their effects on a series of field endurance and technical tests.… Expand
Biomechanical characteristics and determinants of instep soccer kick.
We examine the biomechanics of soccer kick performance and identify weaknesses of present research which deserve further attention in the future. Expand

PURPOSE To examine knee joint kinematics, electromyographic (EMG) activity patterns and ground reaction forces (GRF) during an instep soccer kick from three different approaches relative to the ball.… Expand
Reliability of EMG power-spectrum and amplitude of the semitendinosus and biceps femoris muscles during ramp isometric contractions.
Appropriate reliability is a necessary condition for the use of surface EMG for evaluation of hamstring muscle function in cases of knee joint pathologies or ligament injuries. The aim of the study… Expand
Three-dimensional kinematics and ground reaction forces during the instep and outstep soccer kicks in pubertal players
Abstract The purpose of the present study was to compare the three-dimensional kinematics of the lower extremities and ground reaction forces between the instep kick and the kick with the outside… Expand
Quantification of functional knee flexor to extensor moment ratio using isokinetics and electromyography.
CONTEXT Evaluating moment balance around the knee helps athletic trainers set appropriate targets for injury prevention and rehabilitation programs. OBJECTIVE To examine the knee flexor (KF) to… Expand
The relationship between isokinetic knee extension and flexion strength with soccer kick kinematics: an electromyographic evaluation.
AIM The purpose of this study was to investigate the relationship between isokinetic strength knee testing and soccer kick kinematics using electromyography (EMG). METHODS Thirteen pubertal soccer… Expand
Age and gender differences in kinematics of powerful instep kicks in soccer
Soccer kicking training should be adjusted to the characteristics of the athletes. Therefore, examination of differences in kicking kinematics of females and pubertal players relative to males is… Expand
