Adiposity, Physical Activity and Blood Lipid Profile in 13-year-old Adolescents

Abstract

The main aim of this study was to determine the extent to which physical activity and adiposity are associated with blood cholesterol levels in male adolescents. Anthropometric and physical fitness values were measured in all children. Body mass index (BMI) and physical activity index (PAI) were used to split participants into active overweight (ACO) and non-active normal-weight (NAN) groups. The cutoffs for the ACO group were BMI ≥ 22.6 kg/m 2 and PAI ≥ 3.5, respectively, whereas the corresponding cutoffs for the NAN groups were BMI < 20.0 kg/m 2 and PAI < 2. A total of 65 children (29 in ACO group, 36 in NAN group) were selected according to above criteria. ACO group showed significantly higher BMI and body fat as compared to their NAN counterparts (p < 0.05). Adolescents from ACO group attained superior score for PAI and aerobic fitness (p < 0.05). Most blood lipid variables were significantly lower in ACO group as compared to NAN (p < 0.05) while HDL-cholesterol was higher in ACO group (p < 0.05). There was significant positive correlation between HDLcholesterol and PAI in ACO group (r = 0,38; p < 0.05). Physical activity index explained the majority of variance in HDL-cholesterol for ACO group (β = 0,513; p < 0.05). It seems that physical activity in adolescents is more important factor in balancing blood lipid status than adiposity per se, particularly for HDL-cholesterol.

Phase Angle is Determined by Body Composition and Cardiorespiratory Fitness in Adolescents

“…It is well known that being physically active and having higher levels of cardiorespiratory fitness benefit health, functional ability, quality of life, and longevity [16,17]. Furthermore, a recent metaanalysis showed that children who participated in exercise interventions presented significant reductions in BMI, waist circumference, and %FM as well as increases in cardiorespiratory fitness, lower-body strength, and speed-agility compared to controls [18].…”

“…Furthermore, a recent metaanalysis showed that children who participated in exercise interventions presented significant reductions in BMI, waist circumference, and %FM as well as increases in cardiorespiratory fitness, lower-body strength, and speed-agility compared to controls [18]. Additionally, adolescents who are physically active present higher levels of cardiovascular fitness, a better blood lipid profile, and lower body adiposity [16]. Overall, evidence seems to indicate that being physically active during adolescence can minimize these various health risks [19].…”

Physical Activity Interacts With Adiposity in Determining Cardiometabolic Risk in Adolescents

“…Physical activity has shown to be effective in improving cholesterol levels in adolescents (22). We have determined that higher overall physical activity is associated with lower non-HDL cholesterol, independent of anthropometry category.…”

Effects of the Fitt Program on Physical Activity and Health-Related Fitness in Primary School Age Children

“…Contrary to the many benefits, the physical activity of children of all ages is constantly decreasing (Bornstein, Beets, Byun, & McIver, 2011;Konstabel et al, 2014), and consequently the HRF Ostojić, O`Neil, Calleja, Terrados, & Stojanović, 2010;Ostojić, Stojanović., Stojanović, &, Marić, 2010;Ostojić, Stojanović, Stojanović, Marić, & Njaradi, 2011;Đordjić et al, 2016).…”
