Muscular asymmetry in junior handball athletes in the absence of specific corrective intervention – case studies

Abstract

Muscular asymmetry is a prevalent issue among athletes, particularly in sports that involve repetitive and unilateral movements, such as handball. For junior athletes, these imbalances can significantly impact their physical development, performance, and risk of injury. This article explores the progression of muscular asymmetry in junior handball athletes who do not receive specific corrective interventions, through a series of case studies. Additionaly, it examines the use of the Tanita MC-780 MA body composition analyzer as a tool for assessing and monitoring these asymmetries. The Tanita MC-780 MA provided detailed insights into muscle mass distribution, confirming significant discrepancies between the dominant and non-dominant sides. The progression of muscular imbalance without intervention suggests the need for regular monitoring and targeted training to prevent the exacerbation of asymmetries and associated injuries. The use of the Tanita MC-780 MA proved valuable in precisely quantifying muscle mass differences and tracking changes over time.
