Objective: This review examined the influence of anthropometric characteristics, such as height and body mass, on the impact of punches in striking combat sports. Despite their perceived importance for combat strategy, the relationship between these characteristics and punch impact remains unclear.Methods: We included Experimental, Quasi-experimental and Cross-sectional studies. The search was conducted on August 30, 2024, in three databases. The review analyzed 23 studies involving 381 participants (304 men, 30 women, 47 unknown gender). Various instruments were used in the included studies, including 10 instruments to measure impact force and 2 instruments to measure impact power. Results: Impact force ranged from 989 ± 116.76 to 5008.6 ± 76.3 N, with rear hand straight punches and rear hand hooks producing the greatest force. The PowerKube revealed that the rear hand straight punch generated the highest power, ranging from 15183.27 ± 4368.90 to 22014 ± 1336 W. While heavier weight categories were associated with stronger punches, body mass alone was not the only predictor. Other factors, such as technique, gender, and sport type, also played roles. The relationship between height and punch impact showed mixed results.Conclusion: The data suggest that while higher weight categories are associated with greater punch impact, body mass is not the only determining factor. The relationship between height and impact also showed mixed results, with no clear association. The review highlights the lack of a gold standard instrument for evaluating punch impact.
