Introduction: The kinanthropometric profile and adequate protein intake are key determinants of performance, weight control, and lean mass preservation in combat sports such as boxing.
Objective: To determine whether there is a difference in the kinanthropometric profile and protein intake of amateur and professional boxers in a district of Lima.
Materials and methods: Quantitative, non-experimental, cross-sectional, and descriptive study. One hundred boxers (50 professionals and 50 amateurs) from the Santa Anita district of Lima participated. The kinanthropometric profile was assessed using the ISAK protocol, which includes 28 measurements, and protein intake was estimated using a 24-hour recall.
Results: Professional boxers presented significantly lower body weight (66.9 vs 74.2 kg, p < 0.05), reduced percentage of adipose mass (7.8% vs 9.7%, p < 0.05), and lower residual mass (16.1% vs 17.8%, p < 0.05). Regarding protein intake, professionals showed higher consumption at breakfast (16.4 vs 12.9 g, p < 0.05), mid-morning (8.4 vs 3.0 g, p < 0.05), mid-afternoon (15.8 vs 4.7 g, p = 0.001), and a higher total intake (78.0 vs 56.5 g/day, p < 0.05). Somatotype analysis shows that professionals have significantly lower endomorphy (p < 0.001) and greater moderate ectomorphy (p = 0.016), reflecting a more compact and defined mesomorphic somatotype compared to amateurs.
Conclusion: The results show that competitive level (amateur vs. professional) is associated with significant differences in both the kinanthropometric profile and the daily distribution of protein intake in boxers. These findings support the need to design specific morphological assessment and nutritional planning strategies according to the level of competition, in order to optimize body composition and protein intake throughout the day in boxing athletes.
