Fecha de publicación: | 2010 | Editor: | Thieme | Citación: | International Journal of Sports Medicine 31: 679- 682 (2010) | Resumen: | We examined the role of cardiorespiratory fitness (CRF) on the association between physical activity (PA) and abdominal fat content in adolescents. Abdominal fat content was measured by waist circumference, waist-to-height ratio and dual energy X-ray absorptiometry (DXA) at 3 regions (R1, R2, and R3). PA and CRF were assessed by accelerometry and the 20 m-shuttle run test, respectively. Vigorous PA was inversely associated with waist circumference and waistto-height ratio ( β from − 0.149 to − 0.197; p < 0.05). In both CRF groups (i. e., low and high), vigorous and moderate-to-vigorous PA (also average PA in the low CRF group) were inversely associated with abdominal fat (i. e., R1, R2 and R3; β from − 0.146 to − 0.244; p < 0.05). This association did not diff er according to CRF group (P for interaction > 0.05), yet the percentage of variance in abdominal fat content, when assessed by DXA, explained by PA was slightly higher in adolescents with low CRF (3 – 8 % ) compared to those with high CRF (2 – 4 % ). The fi ndings indicate that there is not a clear interaction eff ect of CRF in the association between PA and abdominal fat in adolescents, yet slightly stronger association was observed in the low fi t group. | URI: | http://hdl.handle.net/10261/112824 | Identificadores: | issn: 0172-4622 |
