The purpose of the present study was to determine the somatotype profile and to assess the prevalence of musculoskeletal disorders (MSDs) according to the somatotype among heavy load carriers. This cross-sectional study was performed on 301 carriers. The method used for determining the somatotype according to Heath and Carter was characterised by calculating the individual components: endomorphic, mesomorphic, ectomorphic. Prevalence of the MSDs was investigated with a Nordic Questionnaire. The neck, shoulders, upper back, lower back, hips/thigh were the body parts in which more than 50% carriers reported MSDs. The MSDs at the level of the wrists/hands was significantly (P <0.001) more frequent in the mesomorphic profile (53.8%) compare to the profiles of endomorphic (10.9%) or ectomorphic (40.9%). In contrast, the frequency of MSDs at the ankles/feet was reported to be significantly higher in the ectomorphic profile (40.0%). This study showed the endomorphic profile to be the most representative among heavy load carriers followed by the ectomorphic profile. If the MSDs at wrists/hands and the ankles/feet were more in mesomorphic and ectomorphic profiles than in endomorph group, the rate of MSDs at the neck, shoulders, upper and lower back, hips/thighs were the same in the three groups.
