The Effect of an Eccentric Contraction Training method on Developing the Maximum Muscle Strength of some Leg Muscles for Powerlifting players

Abstract

Powerlifting is a modern individual sport that relies heavily on muscle strength for success. This activity has distinguished Iraqi club players at both Arab and continental levels. Therefore, it is essential for specialists and researchers to work towards the development of this sport through precise scientific research into the methods and means adopted in training. This effort will enable us to keep pace with advancements in the field and achieve the highest accomplishments that enhance athletic careers. The objective of this research is to create a training curriculum aimed at developing maximum muscle strength through the eccentric contraction of the leg muscles in powerlifting athletes. Additionally, it seeks to investigate the impact of this training curriculum on the maximum muscle strength of powerlifting players. The research sample consisted of six players from the national youth powerlifting team, divided into two groups, each weighing 74 kg and aged between 19 and 21 years. The researcher applied a training curriculum designed for them, which lasted for eight weeks, with a frequency of three training sessions per week. The findings indicated a positive development in muscle strength, with varying degrees of improvement between the groups. Furthermore, there was a significant enhancement in the maximum muscle strength of the players’ legs following the implementation of the training program. The research recommendations emphasize the importance of utilizing the results of this study when developing training methods for powerlifting athletes. It is also crucial to consider the appropriate motor performance pathways related to technical execution when designing training programs.
