To help public health practitioners promote physical activities with a low risk of injury, this study determined the relation among type and duration of physical activity, cardiorespiratory fitness, and musculoskeletal injury in a sample of adults enrolled in the Aerobics Center Longitudinal Study. Subjects included 4,034 men and 967 women who underwent a baseline physical examination between 1...

Electrical stimulation of the cerebellar fastigial nucleus (FN) evokes hyperventilation and hypertension responses that are similar to those induced by stimulation of the medial region of the vestibular nucleus (VNM). Because there are mutual projections between these two nuclei morphologically, we hypothesized that the FN-mediated cardiorespiratory responses were related to the integrity of th...

OBJECTIVE To investigate the association between cardiorespiratory fitness and the incidence of type 2 diabetes among Japanese men. RESEARCH DESIGN AND METHODS This prospective cohort study was conducted in 4747 nondiabetic Japanese men, aged 20-40 years at baseline, enrolled in 1985 with follow-up to June 1999. Cardiorespiratory fitness was measured using a cycle ergometer test, and Vo(2max)...

ABSTRACT: This paper aimed to describe the main clinico-epidemiological, laboratory, and anatomopathological findings in 10 cattle affected with caudal vena cava thrombosis. The clinical signs observed were decreased milk production, reduced appetite, apathy, impairment of ruminal motility, cardiorespiratory disorders (tachycardia tachypnea), epistaxis, hemoptysis, ascites. Intercurrent disease...

The effects of aerobic exercise training in a sample of 85 older adults were investigated. Ss were assigned randomly to either an aerobic exercise group, a nonaerobic exercise (yoga) group, or a waiting-list control group. Following 16 weeks of the group-specific protocol, all of the older Ss received 16 weeks of aerobic exercise training. The older adults demonstrated a significant increase in...

Cardiac and respiratory rhythms are known to exhibit a modest degree of phase synchronization, which is affected by age, diseases, and other factors. We study the fine temporal structure of this synchrony in healthy young, healthy elderly, and elderly subjects with coronary artery disease. We employ novel time-series analysis to explore how phases of oscillations go in and out of the phase-lock...

BACKGROUND Type 2 diabetes mellitus (DM-2) is one of the most prevalent chronic diseases of the aged and contributes to a significant amount of cardiovascular disease morbidity and mortality. Exercise training may be beneficial in attenuating the cardiovascular maladaptations associated with DM-2. The purpose of this study was to examine the effects of exercise training on left ventricular (LV)...

BACKGROUND To our knowledge, detection of cardiorespiratory instability using noninvasive monitoring via electronic integrated monitoring systems (IMSs) in intermediate or step-down units (SDUs) has not been described. We undertook this study to characterize respiratory status in an SDU population, to define features of cardiorespiratory instability, and to evaluate an IMS index value that shou...

OBJECTIVE A study was undertaken to determine whether better cognitive functioning at midlife among more physically fit individuals reflects neuroprotection, by which fitness protects against age-related cognitive decline, or neuroselection, by which children with higher cognitive functioning select more active lifestyles. METHODS Children in the Dunedin Longitudinal Study (N = 1,037) complet...

OBJECTIVE The purpose of this study was to examine independent and joint associations of cardiorespiratory fitness (CRF) and different adiposity measures with mortality risk in individuals with prediabetes (or impaired fasting glucose). RESEARCH DESIGN AND METHODS We examined associations of CRF and fatness with cardiovascular disease (CVD) and all-cause mortality in a cohort of 17,044 partic...
