Investigating the relationship between biomotor components and somatotype of elementary school students in Delfan city

Somatotype represents the morphological shape at certain ages and is associated with cardiorespiratory fitness. The aim of the current research was to investigate the relationship between biomotor variables and the Somatotype of elementary school students in Delfan city.

For this purpose, 150 non-athlete male students with height 152.45±13.85, weight 44.07±12.76 and body mass index of 19.08 ± 3.291 kg/m2 voluntarily participated in this research following the general call of the Fethian Sports Therapy Center. In order to check the Somatotype, selected body measurement variables were used by the Heath and Carter method (ectomorph, mesomorph, endomorph) and to check the biomotor components, vo2max index, anaerobic power and explosive power were used, and the data were analyzed using the analysis test. One-way and Duncan's variance was analyzed using spss version 26 software at the p≤0.05 level.

The results of Pearson's correlation test showed that the relationship between mesomorph body type and biomotor indicators is positive and significant. Also, this relationship was not significant for ectomorph body type with aerobic (p=0.008) and explosive (p=0.009) and anaerobic power index (p=0.213). Regarding the endomorph body type, the results showed a negative relationship with aerobic power (p=0.011) and no relationship with anaerobic and explosive power. Comparing the body types, the findings showed that the VO2max in the mesomorph and ectomorph groups was higher than the endomorph group (p=0.011). In anaerobic performance, participants with mesomorph body type performed better than endomorph and ectomorph body type (p=0.008). Also, in explosive power, participants with mesomorph body type performed better than participants with endomorph and ectomorph body type (p=0.012). but the difference of other groups was not significant.

According to the findings of this research, the ectomorph body type is will talent to aerobic sports and the mesomorph body type is will talent to anaerobic explosive sports, so it is suggested to sports teachers and coaches to pay attention to these points during the talent identify process.
