Description
Summary:Background and objectives: Although physical fitness (PF) is associated with better health outcomes, its direct assessment sometimes in not feasible; therefore surrogates of actual PF are necessary. The aim of this study was to analyze the association between the perception of PF with nutritional status and actual PF in adolescents. Methods: The participants were 319 boys and girls aged 10 to 15 years from Mexico City. Nutritional status with evaluated with body mass index (BMI)-for-age and waist circumference-for-age. Body fat was estimated with Slaughter equation. Each component of PF (aerobic capacity, muscular strength and endurance, and flexibility) was assessed with FITNESSGRAM tests. International Fitness Scale (IFIS) was applied to evaluate the perception of PF. Results: It was observed a high frequency in inadequate aerobic capacity (48.8%), in low strength of trunk, arms and abdomen (60.7%, 63.9% and 42.5% respectively) and flexibility of trunk and legs (68.7%). Most of adolescents did perceive themselves with a good PF (aerobic capacity: 85.2%%, muscular strength: 90.5, flexibility: 74.1%, velocity/agility: 89.6% and general PF: 92.7%). Adolescents with a high adiposity had a low aerobic capacity, muscular strength and flexibility and perceived themselves with inadequate PF. Adolescents that perceived themselves with a good general PF had an adequate aerobic capacity and strength of abdomen and arm. A good perception of aerobic capacity and muscular strength was related with an adequate aerobic capacity and strength of abdomen and arms. The level agreement between FITNESSGRAM battery and IFIS was fair (K= 0.37, p
