The Effect of Lateral Strength Training on Selected Forms of Power, Blocking Performance, and Electromyographic Activity of the Lower Limbs in Under-18 Volleyball Players

Abstract

The present study highlights the importance of employing lateral strength training, which primarily targets under-trained muscles through specific exercises designed to activate and simulate these muscle groups. This approach aims to enhance selected physical abilities and improve volleyball skills that require significant contribution from these muscles. Such training engages the deep muscles extending along the longitudinal axis of the lateral muscles, which are crucial for balance, rapid rotational movements, and instantaneous explosive actions, given the fast-paced nature of volleyball. The purpose of this research was to design lateral strength training programs to develop certain forms of power and blocking performance, and to investigate their effects on power, blocking skill, and the electromyographic (EMG) activity of the lower limbs in under-18 volleyball players. The researcher adopted the experimental method with one equivalent group, which was deemed suitable for addressing the research problem. The sample was selected randomly by lottery and consisted of ten (10) players from Al-Kut Sports Club. The findings of the field experiment revealed that lateral strength training contributed significantly to the development of specific forms of power, positively influencing the execution of the blocking skill among the participants. Moreover, these exercises strengthened the supportive muscles of the prime movers, which enhanced both strength and performance speed. In conclusion, the study recommends emphasizing the integration of lateral strength training into volleyball training programs, as it plays a vital role in developing the physical and technical aspects of young players.
