Abstract
This study aimed to evaluate the effects of a specialized strength fitness program on selected morphological, motor, and functional parameters in competitive boxers. A total of 24 variables were analyzed—10 morphological, 10 motor, and 4 functional—using standardized measurement protocols. eighty (80) participants were divided into an experimental group, which followed a 16-week combined standard training and strength fitness program, and a control group, which followed only the standard training regimen. Dependent sample T-tests were applied to compare initial and final measurements within groups. Results showed that the experimental group experienced statistically significant improvements in all anthropometric measures, including increases in body mass (2.01%), chest circumference (1.47%), and limb circumferences, alongside significant reductions in skinfold thicknesses. Motor abilities improved significantly in tests such as standing long jump (+3.09%), vertical jump (+9.51%), medicine ball throws, and balance. Functional capacity also improved, as indicated by enhanced Åstrand test results (+0.53%) and reduced resting heart rate (-0.92%). No significant changes were observed in systolic or diastolic blood pressure. In contrast, the control group showed modest but significant increases in some anthropometric measures (body mass +0.70%, chest circumference +0.60%) but no significant changes in motor or functional tests. The findings suggest that incorporating a structured strength fitness program alongside standard boxing training effectively enhances morphological, motor, and some functional parameters, thereby potentially optimizing athletic readiness and performance in competitive boxing.
Key words: strength fitness program, boxers, functional parameters
