Effect of Kinetic Resistance Training and Technique on Special Strength Level and Effective Kinematic Variables in Instep Kick for Soccer Juniors

Abstract

Background: Training with resistance is considered the essential and complementary part of players' preparation period during training season through developing different aspects. Objective: This study aims to investigate the Effect of Kinetic resistance training and technique on special power level and effective kinematic variables in instep kick for soccer juniors. Methodology: 20 junior soccer players (age: 17.54 ±0.5 years, body mass: 69.05 kg, height: 170 cm, training age=7.7 years) participated in this study were randomly assigned into two groups experimental (n=10) trained with kinetic resistance training program and technique and control (n=10) trained with traditional soccer training program only where, the experimental approach was used. Results: The kinetic resistance trainings and technique positively affected the special power level, kicking accuracy and time and effective kinematic variables in instep kick. Conclusion: The researcher recommended that coaches should give attention to special strength developing and to be an essential part of the training program through kinetic resistance trainings and technique. Also coaches should depend on the kinematic variables affecting performance for detecting the improvement level in performance as a result of kinetic resistance trainings and technique.

Biomechanical of lower extremity athletic stress and its relationship with performance effectiveness of compound skills for Soccer junior players

“…The transfer of Momentum from the trunk to the thigh, the leg, the foot, then to the ball causes the kicking to become more effective. The results indicate that Momentum of the Segments of the kicking leg is affected by the Quadrant Jump Test and agility, which times have increased in the post-measurement as confirmed by the results of Table (2). While the Force is affected during the kicking skill in the post-measurement with the muscle Force and speed, the statistical significance was negative at the kicking and Follow-up phase for study skills, which well indicates stress of the muscle in the research sample.…”

“…Table (2) The significant differences between the averages of pre-and post-measurements of the physical variables and the effectiveness of kicking of the study sample n = 6 Table (2) shows that there is a statistically significant negative differences between preand post-measurements regarding (Isometric Leg Strength test -Vertical Jump test -accuracy of kicking) for the pre-measurements. This indicates a decrease in the values of these variables in post-measurements.…”
