Central Neural Cardiorespiratory Areas in Exercise
"Neural control of cardiorespiratory function in exercise is accomplished by two mechanisms: a reflex arising from contracting muscles termed ""exercise pressor reflex"", and a ""central command"" mechanism. The three experiments described in this thesis were concerned with fundamental issues …

Cardiorespiratory Influences on Executive Control Function
Cardiorespiratory fitness influences on executive control function were assessed for 72 young adults (23 males). Behavioral and neuroelectric indices of action monitoring were obtained while participants completed both a modified flanker task and a modified Sternberg task under task instruction …

Cardiorespiratory Fitness as a Clinically Relevant Risk Factor
… was to provide evidence in support of cardiorespiratory fitness (CRF) as a clinically relevant tool to manage lifestyle-based disease. The objective of Study 1 was to determine whether there is a difference in all-cause mortality risk between CRF achieved through physical activity (PA) …

Cardiorespiratory fitness in contemporary dance training and performance
… investigation of the relevance and importance of cardiorespiratory fitness in contemporary dance training and performance. Through an initial introduction and literature review, gaps in the current understanding of, and challenges presented by, dance training and performance practices are …

Relationship between cardiorespiratory and muscular parameters and CrossFit performance
Η παρούσα μελέτη είχε ως στόχο να διερευνήσει τη σχέση μεταξύ φυσιολογικών και μυοδυναμικών παραμέτρων με την απόδοση σε τρεις διαφορετικού τύπου δοκιμασίες CrossFit (Cindy, Karen, Double Grace), καθώς και τις πιθανές διαφοροποιήσεις μεταξύ ανδρών και γυναικών. Στη μελέτη συμμετείχαν 20 αθλητές και …

The Association Between Step Intensity and Cardiorespiratory Fitness in Adults
Background: Cardiorespiratory fitness (CRF) is an independent predictor of morbidity and mortality risk. Physical activity is an established, modifiable determinant of CRF, and findings suggest that daily steps are positively associated with CRF. Whether step intensity is associated with CRF has …

Cardiorespiratory Fitness and Cardiovascular Disease Risk Factors in Postmenopausal Women
… becomes similar to that seen in men. Increased cardiorespiratory fitness and use of hormone replacement have been suggested as ways to improve the cardiovascular disease (CVD) risk profile. Unfortunately, very little is known about the effect of cardiorespiratory fitness on the CVD risk profile …

Modelling cardiopulmonary interactions. Towards anatomically detailed and physiologically accurate cardiorespiratory models
… to the increasing healthcare burden related to cardiorespiratory diseases. To this end, physiologically accurate mathematical and computational models can provide an effective tool for the analysis of several physiopathological states and therapeutic strategies through in-silico experiments. …

An Assessment of Obesity Through Lifestyle Self-monitoring and Cardiorespiratory Fitness
… assessing the joint association between cardiorespiratory fitness and excessive body weight compared to mortality. After searching two databases and applying inclusion and exclusion criteria, 9 articles were included in the analysis. Individuals who are fat and also fit had the same risk …

The Importance of Risk Stratification and Cardiorespiratory Fitness in Pediatric Obesity
… both manuscripts displayed the lowest levels of cardiorespiratory fitness, suggesting an increased risk for complications associated with pediatric obesity.

Characterisation of cardiorespiratory responses to electrically stimulated cycle training in paraplegia
… stimulated (FES) cycle training can improve the cardiorespiratory fitness of spinal cord injured (SCI) individuals, but the extent to which this can occur following high volume FES cycle endurance training is not known. The effect of training on aerobic endurance capacity, as determined by the …

Hypothalamic and medullary modulation of cardiorespiratory responses to hypoxia and hypercapnia
… medullary and caudal hypothalamic neurons in the cardiorespiratory response to hypoxia and hypercapnia was examined. Initial experiments performed on anesthetized rats demonstrated that microinjection into the rostral ventrolateral medulla (VLM) of the excitatory amino acid receptor antagonist …

Inclusive and adaptive assessment of cardiorespiratory fitness for population health research
This thesis addresses the challenge of measuring cardiorespiratory fitness (i.e., fitness) in large population studies, overcoming logistical constraints and safety considerations associated with exercise testing that often lead to selection bias and distorted health associations. It presents the …

Cardiorespiratory responses to altered rider position with conventional and aerodynamic handlebars
This investigation evaluated the cardiorespiratory responses to three rider positions while undergoing maximal cycle ergometry. The positions were determined by the position of the hands on the handlebars and the posture of the upper body: upright (UP), and drop position (DP) with conventional …

Cardiorespiratory fitness as a cardiovascular protective mechanism of endothelial dysfunction with aging
… exercise with aging leads to improvements in cardiorespiratory fitness (CRF) and preserves endothelial function in preclinical models via lower mitochondrial-derived ROS (mtROS) however, these effects have yet to be fully translated to humans. Here, we sought to investigate if an underlying …

The Impact of Cardiorespiratory Fitness on Cytotoxic T Cell Function and Metabolism
Cardiorespiratory fitness (CRF) is a key indicator of the health and function of several bodily systems, but it is unknown how CRF impacts the function of specific immune cells such as cytotoxic CD8+ T cells (Tc). Tc utilize cytokines, such as interferon-γ (IFN-γ), to orchestrate cell mediated …

Racial Differences in Cardiorespiratory Fitness between Blacks and Whites: A Meta-Analysis
PURPOSE: Cardiorespiratory fitness (CRF) is a major risk factor for cardiovascular disease (CVD), all-cause mortality and CVD mortality. Some researchers have speculated that Blacks have lower levels of CRF when compared to Whites, which may contribute to the health disparities in CVD. However, …

Physical activity, cardiorespiratory fitness, memory, and self-efficacy in the aging brain
… previous research has demonstrated that cardiorespiratory fitness (Colcombe, Kramer, McAuley, Erickson, & Scalf, 2004; Erickson et al., 2011; Kramer et al., 1999) and physical activity (Angevaren, Aufdemkampe, Verhaar, Aleman, & Vanhees, 2008; Flöel et al., 2010) also can increase or help …
