Public ISBD [article]  inScience & motricité > 113 [23/11/2021] . - p. 1-9 Titre : Musculoskeletal profile of amateur combat athletes : bodycomposition, muscular strength and striking power Type de document : texte imprimé Auteurs : Luke Del Vecchio ; Nattai Borges Année de publication : 2021 Article en page(s) : p. 1-9 Note générale : 2021https://doi.org/10.1051/sm/2021004Science Langues : Français (fre) Mots-clés : muscular balance  mixed martial arts  bone density  lean muscle  punch  kick Résumé : Previous research highlighted positive musculoskeletal adaptations resulting frommechanical forces and loadings distinctive to impacts and movements with sports participation. However, littleis known about these adaptations in combat athletes. The aim of this study was to quantify bone mineraldensity, lean muscle mass and punching and kicking power in amateur male combat athletes.Methods:Thirteen male combat athletes (lightweight and middleweight) volunteered all physiological tests includingdual energy X-ray absorptiometry for bone mineral density (BMD) segmental body composition (lean musclemass, LMM), muscle strength and striking power, sedentary controls (n= 15) were used for selected DXAoutcome variables.Results:There were significant differences (p<0.05) between combat groups for lumbarspine (+5.0%), dominant arm (+4.4%) BMD, and dominant and non-dominant leg LMM (+21.8% and+22.6%). Controls had significantly (p<0.05) high adiposity (+36.8% relative), visceral adipose tissue (VAT)mass (+69.7%), VAT area (+69.5%), lower total body BMD ( 8.4%) and lumbar spine BMD ( 13.8%) thancontrols. No differences in lower limb BMD were seen in combat groups. Arm lean mass differences (dominantversusnon-dominant) were significantly different between combat groups (p<0.05, 4.2%versus7.3%). Therewere no differences in punch/kick power (absolute or relative) between combat groups. 5RM strength (benchand squat) correlated significantly with upper limb striking power (r= 0.57), dominant and non-dominant legBMD (r= 0.67,r= 0.70, respectively) and total body BMD (r= 0.59).Conclusion:BMD and LMM appear tobe particularly important to discriminate between dominant and non-dominant upper limbs and less so forlower limb dominance in recreational combat athletes.
