OBJECTIVE To evaluate the prevalence of low aerobic fitness levels and to analyze the association with sociodemographic factors, lifestyle and excess body fatness among adolescents of southern Brazil. METHODS The study included 879 adolescents aged 14 to 19 years the city of São José/SC, Brazil. The aerobic fitness was assessed by Canadian modified test of aerobic fitness. Sociodemographic va...

background: regular moderate intensity physical activity and lipid lowering effects of nigella sativa(n. sativa) supplementation may be appropriate management for sedentary overweight females. therefore, the aim of the present study was to examine the effects of long-term n. sativasupplementation and aerobic training on lipid profile and maximal oxygen consumption (vo2max) in sedentary overweig...

Vitamin C consumption is important in Iron absorption. Therefore, the purpose of this study was to investigate the effect of acute aerobic activity after two weeks vitamin C supplementation on Iron status and hematological indices in club football players. In this quasi-experimental study, 40 club football players from Khuzestan province were randomly divided into two groups of vitamin C and pl...

INTRODUCTION Although the effects of aerobic physical activity (APA) on children's physical health is well characterized, the effect of aerobic physical activity on cognition, academic achievement, and psychosocial function has not yet been established. This systematic review provides an overview of research elucidating the relationship between aerobic physical activity and children's cognition...

Increased glucose metabolism and reprogramming toward aerobic glycolysis are a hallmark of cancer cells, meeting their metabolic needs for sustained cell proliferation. Metabolic reprogramming is usually considered as a downstream consequence of tumor development and oncogene activation; growing evidence indicates, however, that metabolism on its turn can support oncogenic signaling to foster t...

OBJECTIVES Recent studies have indicated reduced immunity in trained athletes. AIM To assess the effects of aerobic and anaerobic exercise on the phagocytic process in 18-26 year old trained female judoka (n = 8) and untrained controls (n = 7). METHODS Each subject participated randomly in two different testing sessions (aerobic, 20 minutes of treadmill running at 70-80% of maximal heart ra...

Recent studies have shown that during unimanual motor tasks, aging adults show bilateral recruitment of primary motor cortex (M1), while younger adults show a suppression of the ipsilateral motor cortex. Additional work has indicated that increased bilateral M1 recruitment in older adults may be deleterious when performing some motor tasks. However, higher levels of physical fitness are associa...

Differences in the limits and range of aerobic activity levels between endotherms and ectotherms remain poorly understood, though such differences help explain basic differences in species' lifestyles (e.g. movement patterns, feeding modes, and interaction rates). We compare the limits and range of aerobic activity in endotherms (birds and mammals) and ectotherms (fishes, reptiles, and amphibia...
