A systematic literature review suggests that particulate air pollution is associated with daily admissions for both respiratory and cardiac diseases in people aged > 65 yrs. A model of acute effects is proposed which shows how admissions can be brought forward by a relatively short period of time as well as events being added that would not have happened at all except for air pollution. A model...

Blastomyces dermatitidis is a fungus that is found primarily in endemic areas of the midwestern and southcentral USA. Blastomycosis pneumonia may develop after the inhalation of spores. While blastomycosis may lead to acute or chronic pneumonitis, it will rarely result in the development of the acute respiratory distress syndrome (ARDS). In this situation, mortality rates are 50–80%. Patients w...

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...

background: maximal volume oxygen is an accepted standard for measuring cardiorespiratory readiness. this factor indicates the power of physiological adoption for increasing activity time and efficiency of cardiovascular system. the objective of this study was to find out an optimal correlation between maximal volume oxygen and maximal voluntary ventilation indicators and their effect on cardio...

Examine the association between health-related physical fitness (cardiorespiratory and muscular fitness) skill-related (speed-agility) both cognitive functions academic achievement in adolescents (12–15 years). Data of 423 Dutch were analyzed (46.8% boys, age = 13.45 ± 0.43 Physical was assessed using five subtests Eurofit test battery measuring cardiorespiratory (20 m Shuttle Run Test), (Broad...

Previous research has reported the validity and reliability of a range of field-based tests of children's cardiorespiratory fitness. These two criteria are critical in ensuring the integrity and credibility of data derived through such tests. However, the criterion of scalability has received little attention. Scalability determines the degree to which tests developed on small samples in contro...

BACKGROUND Project ACTIVE was a randomized clinical trial comparing two physical activity interventions, lifestyle and traditional structured exercise. The two interventions were evaluated and compared in terms of cost effectiveness and ability to enhance physical activity among sedentary adults. DESIGN This was a randomized clinical trial. SETTING/ PARTICIPANTS The study included 235 seden...

For most of human history, the environmental demands of survival necessitated prodigious amounts of physical exertion. The avoidance of predators, hunting, gathering, and the literal "chopping wood and carrying water" of daily existence provided a wholesome dose of physical activity that obviated the need for deliberate exercise. Nevertheless, 21st century humans are now immersed within an envi...

The objective of this trial was to assess the long-term effect of the CHANGE lifestyle coaching intervention for 428 people with abdominal obesity and schizophrenia spectrum disorders on cardiovascular risk. In this randomized, superiority, multi-center clinical trial, participants were randomized to 12 months of either lifestyle coaching plus care coordination (N = 138), care coordination alon...

OBJECTIVE Low cardiorespiratory fitness (CRF) is an independent risk factor for cardiovascular disease (CVD), especially in individuals with type 2 diabetes. Age-predicted, sex-stratified, and maximal MET cut points have been developed to determine the risk of CVD events and mortality in low CRF categories. We examined the proportion of Health Benefits of Aerobic and Resistance Training in Indi...
