The Effect of Slow-Rhythm Training on The Maximum Strength of Working Muscles and the Digital Achievement of the Deadlift for Young Weightlifters in Physical Strength

Abstract

This research investigates the effectiveness of a slow-rhythm training technique aimed at enhancing the maximum strength of lifters, particularly in the deadlift. The study arose from the researcher’s observations of stagnant performance levels among weightlifters, despite traditional training methods that typically employ a single movement rhythm at natural speeds. Noting a deficiency in maximum strength values through preliminary muscle strength tests, the researcher sought to implement a slow-rhythm approach, which involves performing exercises at varying speeds to influence specific chemical variables and improve strength outcomes. The research targeted the bodybuilding weightlifters of the Najaf Governorate youth team, comprising 40 athletes affiliated with the Iraqi National Federation. A sample of 20 lifters, aged 19-23, was randomly selected and divided into two groups: an experimental group and a control group, each consisting of 10 participants. The experimental method was employed to align with the research objectives. The findings indicated that the slow-rhythm technique significantly enhanced maximum muscle strength values among the athletes. This improvement is attributed to the adaptations within muscle cells resulting from the high training loads applied at different speeds, thereby increasing the muscles' capacity to generate force. The study concluded that such adaptations positively affected deadlift performance, which is inherently characterized by slow execution. Data analysis was conducted using SPSS and Excel, reinforcing the efficacy of the slow-rhythm training method in developing strength in young lifters. Overall, the research contributes valuable insights into innovative training methodologies that can lead to improved athletic performance in weightlifting.
