Physical exercise has been shown to improve cognitive functions. However, it is still unknown which type of exercise affects cognition. In the present study, we tested the hypothesis that a demanding balance training program improves memory and spatial cognition. Forty healthy participants aged 19-65 years were randomly assigned to either a balance or relaxation training intervention. Each group exercised twice a week for a total of 12 weeks. Pre- and posttests assessed balance performance, cardiorespiratory fitness, memory, spatial cognition, and executive functions...

OBJECTIVE: This study comprehensively explores racial/ethnic disparities in waist circumference (WC) after adjusting for cardiorespiratory fitness (CRF), among both adult and adolescent women, across WC percentiles. METHODS: Analysis was conducted using data from the 1999 to 2004 National Health and Nutrition Examination Survey. Female participants (n = 3,977) aged 12-49 years with complete data on CRF, height, weight and WC were included. Quantile regression models, stratified by age groups (12-15, 16-19 and 20-49 years), were used to assess the association between WC and race/ethnicity adjusting for CRF, height and age across WC percentiles (10th, 25th, 50th, 75th, 90th and 95th)...

Purpose: Having a low level of physical fitness, especially cardiorespiratory fitness, appears to accelerate age-related aortic stiffening. Whereas, some studies have reported that trunk flexibility is a component of physical fitness, it is also negatively associated with arterial stiffening independent of cardiorespiratory fitness in cross-sectional studies. However, no long-term longitudinal study has determined whether poor trunk flexibility accelerates the progression of age-related aortic stiffening. We examined trunk flexibility and aortic stiffness progression in a 5-year longitudinal study...

BACKGROUND: Testicular cancer survivors (TCS) have an increased risk of treatment-related cardiovascular disease (CVD), which may limit their overall survival. We evaluated the effects of high-intensity aerobic interval training (HIIT) on traditional and novel CVD risk factors and surrogate markers of mortality in a population-based sample of TCS. METHODS: This phase 2 trial (ClinicalTrials.gov identifier NCT02459132) randomly assigned 63 TCS to usual care (UC) or 12 weeks of supervised HIIT (ie, alternating periods of vigorous-intensity and light-intensity aerobic exercise)...

Few data are available regarding the influence of body phenotype on systemic hypertension (SH) and whether cardiorespiratory fitness (CRF) attenuates this relation. We tested the hypothesis that obesity phenotypes and CRF would predict incident hypertension, evaluating 3,800 Korean men who participated in 2 health examinations in1998 to 2009. All participants were normotensive at baseline and were divided into 4 groups based on body mass index using the Asia-Pacific descriptors for obesity and metabolic health status and the National Cholesterol Education Program's adult treatment panel III (ATP-III) criteria...

Background: Previous studies have shown associations of physical fitness and cognition in children and in younger and older adults. However, knowledge about associations in high-school adolescents and young adults is sparse. Thus, the aim of this study was to evaluate the association of physical fitness, measured as maximal oxygen uptake ([Formula: see text]), muscle mass, weekly training, and cognitive function in the executive domains of selective attention and inhibitory control, in healthy male high-school students...

Cardiorespiratory fitness (CRF), an index of cardiac and respiratory functioning, is strongly associated with a reduced risk of adverse health outcomes. We aimed to assess the prospective association of CRF with the risk of respiratory diseases (defined as chronic obstructive pulmonary disease, pneumonia, or asthma). Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed in 1974 middle-aged men. During a median follow-up of 25.7 years, 382 hospital diagnosed respiratory diseases were recorded...

Obesity has become a major public health concern over the past several decades and has been shown to be associated with type 2 diabetes, cardiovascular diseases, dyslipidemia, hypertension, osteoarthritis (OA), and certain types of cancer. The impact of excess weight on cardiovascular and musculoskeletal health is not well-summarized in the literature, and there are some contradictory reports. Therefore, the purpose of this study was to assess the impact of body mass index (BMI) on: 1) cardiovascular outcomes; 2) osteoarthritis risk and progression; and 3) total knee arthroplasty outcomes (TKA)...

The cardiovascular benefits of regular exercise have been well described, including a significant reduction in cardiovascular morbidity and mortality for those meeting recommended guidelines. Yet the impact of physical activity on the incidence of atrial fibrillation (AF) has been less clear. This review seeks to define the optimal dose and duration for the prevention and treatment of AF. In doing so, we review the evidence that supports a decline in AF risk for those who achieve a weekly physical activity dose slightly above the current recommended guidelines...

Heart Failure (HF) results in high healthcare costs and burdens for the United States both in respects to hospitalizations, therapies, and associated disability. The relative proportion of HF with preserved ejection fraction (HFpEF) compared with HF with reduced ejection fraction (HFrEF) is on the rise; HFpEF has already become the dominant form of HF and it continues to increase. The serious implications of these trends are compounded by a dearth of effective HFpEF therapies. While low physical activity, low cardiorespiratory fitness (CRF), and obesity, are risk factors for HF in general, they particularly predispose to HFpEF...

BACKGROUND: Few studies have quantified cardiorespiratory fitness among individuals seeking bariatric surgery. Treadmill testing allows researchers to determine exercise capacity through metabolic equivalents (METs). These findings can assist clinicians in understanding patients' capabilities to carry out various activities of daily living. The purpose of this study was to determine exercise tolerance, and the variables associated with fitness, among individuals seeking bariatric surgery...

BACKGROUND: The oxygen (O2 ) pulse curve obtained at cardiopulmonary exercise testing provides information on cardiorespiratory fitness and the presence of cardiovascular disease. O2 pulse abnormalities have been attributed to myocardial ischemia, among other conditions, but the predictors of abnormal O2 pulse curves are not completely known. HYPOTHESIS: Perfusion abnormalities detected by myocardial perfusion scintigraphy (MPS) may be associated with abnormal O2 pulse curves...

Impaired cardiorespiratory fitness (CRF) is closely linked to chronic illness and associated with adverse events. The American College of Sports Medicine (ACSM) regression equations (ACSM equations) developed to estimate oxygen uptake have known limitations leading to well-documented overestimation of CRF, especially at higher work rates. Thus, there is a need to explore alternative equations to more accurately predict CRF. We assessed maximal oxygen uptake (VO2 max) obtained directly by open-circuit spirometry in 7,983 apparently healthy subjects who participated in the Fitness Registry and the Importance of Exercise National Database (FRIEND)...
