An analysis of cardiorespiratory dynamics during mental arithmetic, which induces stress, and sustained attention was conducted using information theory. The information storage and internal information of heart rate variability (HRV) were determined respectively as the self-entropy of the tachogram, and the self-entropy of the tachogram conditioned to the knowledge of respiration. The informat...

QUESTIONS What factors influence the decision making of cardiorespiratory physiotherapists in acute care? How do cardiorespiratory physiotherapists manage multiple factors in their decision making? DESIGN Qualitative study using observation and semi-structured interviews. PARTICIPANTS Fourteen physiotherapists working in acute cardiorespiratory care. RESULTS Cardiorespiratory physiotherap...

The aim of this study was to investigate the independent associations among cardiorespiratory fitness, metabolic syndrome (MetS), and C-reactive protein (CRP) in children. The sample consisted of 112 children (11.4  ±  0.4 years). Data was obtained for children's anthropometry, cardiorespiratory fitness, MetS components, and CRP levels. MetS was defined using criteria analogous to the Adult Tre...

BACKGROUND In Japan, although the incidence of overweight (BMI ≥ 25) is still low compared with that in Europe and the United States, the prevalence of type 2 diabetes has increased over the last 15 years,. In both Japanese and Caucasian populations it has been reported that a high level of cardiorespiratory fitness protects against the development of type 2 diabetes. However, there are no repo...

Hyperbilirubinemia (HB) occurs in 90% of preterm newborns. Moderate HB can induce acute neurological disorders while severe HB has been linked to a higher incidence of apneas of prematurity. The present study aimed to test the hypothesis that even moderate HB disrupts cardiorespiratory control in preterm lambs. Two groups of preterm lambs (born 14 days prior to term), namely control (n = 6) and...

Short leukocyte telomere length (LTL) has become a hallmark characteristic of aging and is associated with higher morbidity and mortality. Physical activity (PA) has been implicated in attenuating age-induced diseases by, for example, preserving LTL. Results from studies of the relationship between PA and LTL have been mixed, which might be because PA was assessed over a short period of time. T...

Exposure to nitrate is toxic aquatic animals due the formation of methaemoglobin and a subsequent loss blood-oxygen carrying capacity. Yet, toxicity can be modulated by other stressors in environment, such as elevated temperatures. Acclimation temperatures has been shown offset negative effects on whole animal performance fish, but mechanisms underlying this cross-tolerance interaction remain u...

Epidemiological investigations have revealed increases in the prevalence of sedentary behaviors in industrialized societies. However, the implications of those lifestyle choices and related cardiorespiratory fitness levels for memory function are not well-understood. To determine the extent to which cardiorespiratory fitness relates to the integrity of multiple memory systems, a cross-sectional...

OBJECTIVE To investigate the correlation between cardiorespiratory fitness and mood state in individuals with temporal lobe epilepsy (TLE). METHOD Individuals with TLE (n = 20) and healthy control subjects (C, n = 20) were evaluated. Self-rating questionnaires were used to assess mood (POMS) and habitual physical activity (BAECKE). Cardiorespiratory fitness was evaluated by a maximal incremen...

BACKGROUND Light-emitting diodes (LED) have been used to minimize muscle fatigue in athletes and healthy subjects. Patients with chronic obstructive pulmonary disease (COPD) are susceptible to early muscle fatigue. OBJECTIVE The objective of this study is to investigate the acute effects of LED on muscle function, exercise capacity and cardiorespiratory responses during isometric and dynamic ...
