A group of adolescents with postural distortion in the sagittal plane were used as a sample group to study the relations between anthropometric characteristics and motor abilities. The total sample included 202 students (79 boys and 123 girls). Their posture was evaluated using the somatoscopic method by Napoleon Wolanski. Anthropometric characteristics (11) and motor abilities (12) were brought into correlation with the aim of determining causal links of the postural disorders affecting the sagittal plane. The results show considerable individual differences in anthropometric characteristics and the level of motor abilities in both genders. Generally speaking, we may conclude that the respondents with the postural distortion in the sagittal plane have either a similar body-build or poorly developed certain motor abilities.
