Research on influencing factors of adolescents' sports health behaviors in social ecology

Rev. bras. med. esporte; 27 (4), 2021
ABSTRACT Introduction: Physical exercise has a positive effect on the health of individuals. Long-term sedentary behavior can induce coronary heart disease, hypertension, diabetes, and other chronic diseases. Lack of physical exercise has become the fourth leading cause of death worldwide. Therefore, yo...

Change and development law of adolescents' physical health exercise behavior

Rev. bras. med. esporte; 27 (4), 2021
ABSTRACT Background: The generation of individual behavior is closely related to the environment in which it is located and is easily affected by environmental factors. Objective: The thesis takes the social ecology model theory as the starting point, applies the five different levels of influencing fa...

Experimental research on forecasting index of biological image aerobic exercise analysis of artificial neural network

Rev. bras. med. esporte; 27 (4), 2021
ABSTRACT Objective: The paper uses artificial neural network images to explore the effects of aerobic exercise on the gamma rhythm of theta period in the awake hippocampal CA1 area of APP/PS1/tau mice and the low-frequency gamma rhythm of the sleep state hippocampal CA1 area SWR period. Methods: Clean ...

Research on athlete's aerobic and anaerobic exercise ability with balanced nutrition

Rev. bras. med. esporte; 27 (4), 2021
ABSTRACT Introduction: The need for a lactic acid cycle eliminates lactic acid produced during exercise. This process requires energy consumption. D-ribose supplementation can increase muscle cell energy, accelerate the synthesis of PRPP in the heart and skeletal muscle, and eliminate the pentose phosph...

Measurement of local consistency of the whole brain after aerobic exercise based on magnetic resonance imaging

Rev. bras. med. esporte; 27 (4), 2021
ABSTRACT Introduction: The rapid development of rs-fMRI in recent years can provide new scientific evidence of the plasticity of the child's brain. Objective: To reveal the effect of short-term moderate-intensity aerobic exercise on local consistency of brain function in children at rest, and to provid...

Prevalence of physical activity and associated factors among pregnant women: a cross-sectional population-based study in southern Brazil

Abstract Objectives: to describe the prevalence of sufficient leisure-time physical activity (LPA) in the trimesters of pregnancy and to test its association with sociodemographic and contextual characteristics. Methods: cross-sectional study that in 2019 analyzed data from 3580 pregnant women residing...

Reduced naïve T cell numbers correlate with increased low-grade systemic inflammation during ageing and can be modulated by physical activity

Int. j. morphol; 39 (3), 2021
SUMMARY: Age-associated decline of immune system, termed immunosenescence, is characterized by low-grade systemic inflammation, known as inflammaging, together with T-cell functional dysregulation. Although affecting all individuals, different environmental as well genetic factors impinge on the individu...
