OBJECTIVES To explore the associations between objectively assessed intensity levels of physical activity and academic achievement and test whether cardiovascular fitness mediates the association between physical activity and academic achievement. STUDY DESIGN Cross-sectional data were gathered in Swedish 9th-grade students (n = 232; mean age = 16 years; 52% girls). School grades, pubertal ph...

The aim of this retrospective study is to evaluate the cardiovascular fitness and muscle strength performance children with asthma versus without. Participants include patients who were involved in 2012 NHANES National Youth Fitness Survey (NNYFS) as published by Centers for Disease Control Prevention. average scores will be appreciated analyzing averages time spent on treadmill, maximal heart ...

BACKGROUND Imbalances of the autonomic nervous (ANS), the cardiovascular system, and ionics might contribute to the manifestation of The Brugada Syndrome (BrS). Thus, this study has aimed to investigate the cardio-respiratory fitness and the responses of the ANS both at rest and during a sub-maximal exercise stress test, in BrS patients and in gender-matched and age-matched healthy sedentary co...

In [1], a mathematical model is proposed. It is an ODE model of Blood Partial Pressures in Human Cardiovascular-Respiratory System. This model consists of two components: systemic arterial compartment and systemic venous compartment. This model has been important in the field of mathematical modeling of Cardiovascular-Respiratory System. We introduce a time delays to the model to describe the t...

PURPOSE To compare the effects of six weeks of high intensity interval training (HIIT) vs continuous moderate intensity training (MIT) for improving body composition, insulin sensitivity (SI), blood pressure, blood lipids, and cardiovascular fitness in a cohort of sedentary overweight or obese young men. We hypothesized that HIIT would result in similar improvements in body composition, cardiov...

BACKGROUND Recent studies have demonstrated a strong association between physical activity, low level of cardiorespiratory fitness and the presence of cardiovascular risk factors. OBJECTIVE Compare the level of physical activity, level of cardiorespiratory fitness and cardiovascular risk in students of medicine and physical education. METHODS At the first phase, the International Physical A...

OBJECTIVES This study explores whether cardiovascular fitness levels and senescent decline are similar in the Tsimane of Bolivia and Canadians, as well as other subsistence and industrialized populations. Among Tsimane, we examine whether morbidity predicts lower levels and faster decline of cardiovascular fitness, or whether their lifestyle (e.g., high physical activity) promotes high levels a...

Adults with intellectual disability (ID) have decreased cardiovascular fitness and strength present with lower rates of physical activity (PA), and often have balance and functional impairments. The purpose of this study was to investigate the effect of a combined PA program (CPAP) utilizing aerobic, strength and balance training on cardiovascular fitness, strength, balance and functional measu...
