REVIEW
Samir Nusair
The incremental cardiopulmonary exercise test (CPET) is an increasingly used diagnostic method that serves to evaluate patients with chief complaint of dyspnea during exercise. Performing maximal symptom-limited CPET can show if the tested subject has a reduced exercise capacity and give clues to the mechanism of such exercise capacity reduction, cardiac, pulmonary, or pulmonary vascular source. In this review, it is suggested that the evaluation of the complex results of CPET should be performed by first determining if myocardial/circulatory insufficiency is present and second if there is gas exchange abnormality...

BACKGROUND: Physical inactivity and low resting heart rate variability (HRV) are associated with an increased cardiovascular deconditioning, risk of secondary stroke and mortality. Aerobic dance is a multidimensional physical activity and recent research supports its application as a valid alternative cardiovascular training. Furthermore, technological advances have facilitated the emergence of new approaches for exercise training holding promise, especially those methods that integrate rehabilitation with virtual gaming...

INTRODUCTION: Chronic heart failure (CHF) is characterized by dyspnea and poor exercise tolerance, which decreases aerobic capacity (V˙O2peak), a measure strongly correlated with quality of life and mortality. In healthy populations, eccentric (ECC) cycling can be performed at a lower oxygen demand for matched workload, compared to concentric (CON) cycling, but few studies have previously investigated ECC cycling in CHF. We hypothesized that, when matched for external workload (Watts), an ECC cycling bout would be performed at a lower cardiorespiratory load (V˙O2) than CON in patients with CHF...

Individuals with spinal cord injury (SCI) experience life-threatening cardiovascular events and various autonomic consequences in addition to the well-appreciated motor and neurological impairments. As a result, cardiovascular disease is a major cause of death after SCI, corresponding to a 2-4 fold increased risk of cardiovascular events. A combination of neuroanatomical changes, unstable blood pressure, and rapid deconditioning as a result of decreased physical activity likely contributes to accelerated cardiovascular disease progression in after SCI...

Dyspnoea is a complex, highly personalized and multidimensional sensory experience, and its underlying cause and mechanisms are still being investigated. Exertional dyspnoea is one of the most frequently encountered symptoms of patients with cardiopulmonary diseases, and is a common reason for seeking medical help. As the symptom usually progresses with the underlying disease, it can lead to an avoidance of physical activity, peripheral muscle deconditioning and decreased quality of life. Dyspnoea is closely associated with quality of life, exercise (in)tolerance and prognosis in various conditions, including chronic obstructive pulmonary disease, heart failure, interstitial lung disease and pulmonary hypertension, and is therefore an important therapeutic target...

Spinal cord injury (SCI) is a traumatic, life-disrupting event with an annual incidence of 17,000 cases in the US. SCI is characterized by progressive physical deconditioning due to limited mobility and lack of modalities to allow safe physical activity that may partially offset these deleterious physical changes. Approximately, 50% of patients with SCI report no leisure-time physical activity and 15% report leisure-time physical activity below the threshold where meaningful health benefits could be realized...

PURPOSE: Long-term exercise training is associated with characteristic cardiac adaptation, termed athlete's heart. Our research group previously characterized in vivo left ventricular (LV) function of exercise-induced cardiac hypertrophy in detail in a rat model, however the effect of detraining on LV function is still unclear. We aimed at evaluating the reversibility of functional alterations of athlete's heart after detraining. METHODS: Rats (n=16) were divided into detrained exercised (DEx) and detrained control (DCo) groups...

Muscle deconditioning is commonly observed in patients surviving sepsis. Little is known regarding the molecular mechanisms regulating muscle protein homeostasis during the recovery or convalescence phase. We adapted a sepsis-recovery mouse model that uses cecal ligation and puncture (CLP), followed 24 h later by cecal resection and antibiotic treatment, to identify putative cellular pathways regulating protein synthesis and breakdown in skeletal muscle. Ten days after CLP, body weight and food consumption did not differ between control and sepsis-recovery mice, but gastrocnemius weight was reduced...

BACKGROUND: Discriminating circulatory problems with reduced stroke volume from de-conditioning in which the muscles cannot consume O2 normally by gas exchange parameters is difficult. METHODS: We performed combined stress echo and cardio-pulmonary (CPET) tests in 110 patients (20 normal effort capacity, 54 attenuated stroke volume response, 36 de-conditioning) to evaluate multiple hemodynamic parameters and oxygen content difference (A-VO2 Difference) in four predefined activity levels to assess which of the gas measures may help in the discrimination...

Since the late 1980s, lung transplant has become an option for some individuals (in 2014 4000 lung transplants were performed) with end-stage lung disease aimed to help these individuals restore function and improve survival and quality of life. Individuals living with end-stage lung disease are already deconditioned with poor endurance and limited exercise capacity. There are additional post-transplant factors which can contribute to poor endurance and decreased exercise capacity. While pulmonary rehabilitation in the pre-transplant phase is a crucial component for positive functional outcomes following lung transplant, the incidence of post-transplant complications, coupled with the need for immunosuppression often warrants close monitoring by medical professionals...

The Montévrain clinic wants to be a medical center oriented towards autonomy and recovery of patient autonomy, reintegration within the family, as well as social and professional reintegration. After studying the care offer and the population base in Seine et Marne, we wanted to get involved in order to improve the capacity of patients treated for breast cancer, suffering deconditioning, with or without joint limitation and functional impairment, with or without a mental deterioration. We studied the recommendations of the "plan cancer III", researched the tertiary phase of cancer treatment and studied literature about evaluation of the physical and mental condition...

OBJECTIVE: Fibromyalgia fatigue was described as an overwhelming feeling of tiredness that is not relieved by sleep or rest and is often not in proportion to the effort realized. In fibromyalgia syndrome (FMS), the fatigue has an important functional impact, often limiting the activities of daily living, can induce a state of deconditioning, and causing disturbance of locomotion, whose reasons are not fully understood. The aims of this study was to evaluate the postural performance in quite standing of FMS patients, and to compare them to a control group, and to assess the influence on the posture of a fatigue induced by a short walk...
