Prevalence of unilateral hypertrophy of trapezius muscle in boxers

Background: Boxers may be particularly prone to developing hypertrophy of the trapezius muscle, particularly on one side of the body, due to both the nature of their sport and the training methods they employ. While the prevalence of trapezius muscle hypertrophy in boxers remains largely unexplored, there are indications that this condition may be common. So, this research seeks to provide valuable insights and documentation regarding its occurrence.Methodology: An observational study was conducted on 50 male boxers aged 18-30 years. Boxers with at least three years of consistent exercise experience, with at least five to six sessions each week were chosen randomly for this investigation. The outcome measures were hypertrophy and strength measurements. Results: According to the findings of this study, 48% of 50 boxers had unilateral trapezius muscle hypertrophy. To investigate the relationship between unilateral hypertrophy and trapezius muscular strength, a Chi-square test was used with SPSS software, and the Pearson value was 0.370. The test results show that there is no statistically significant relationship between hypertrophy and strength.Conclusion: The study concludes that the prevalence of unilateral trapezius muscle hypertrophy was 48%. Irrelevant to the side of hypertrophy, the subject having unilateral side greater trapezius muscle strength, and this study could not establish an association between unilateral hypertrophy and trapezius muscle strength, and there was also no association between unilateral side hypertrophy and dominance.
