Motor fitness in relation to body build and physical activity in 16–18-year-old youth
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2011, Vol 21, Issue 55
Abstract
[b]Aim of the study.[/b] The research was designed to find out whether physical activity analyzed along with somatic parameters would prove to be crucial for motor fitness in youth.[b]Material and methods.[/b] The data includes surveys and measurements collected from secondary school students from Głuchołazy, aged 16–18. Three hundred and forty-five students, 165 boys and 178 girls, were measured for body height and mass with which the body mass index (BMI) was calculated. Body build was characterized by tissue components in Sheldon’s typology modified by Heath and Carter (endomorphy, mesomorphy and ectomorphy). The motor abilities level was tested by means of five fitness trials for strength, speed and coordination and additionally, a questionnaire with questions on the amount of time spent on physical activity and passive activities in free time was used. The data was processed statistically, arithmetic means and standard deviations of traits for age and sex groups were calculated, and the forward stepwise regression method was employed.[b]Results.[/b] In boys the most important factors in the level of particular motor abilities are the muscles of the upper limb, the endomorphy component indicating the body adiposity and massiveness of lower limb bones. The girls’ motor fitness correlates significantly with the time spent weekly on physical activity and passive activities after school. Additionally, somatic parameters were selected – the musculature of the upper and lower limbs, body build slenderness and massive bone structure of the upper limbs.[b]Conclusion.[/b] Physical activity manifested itself as an important factor affecting only motor fitness in girls, whilst in boys the level of the selected motor abilities was affected solely by somatic features of the organism and not by the analyzed factors pertaining to lifestyle.
