BACKGROUND: The relationship between insomnia and cardiorespiratory fitness (CRF), a well-established risk factor for cardiovascular disease, has not been extensively studied. We aimed to assess the independent association between insomnia and CRF in a population-based cohort of subjects aged 50 to 64 years. METHODS: Subjects participating in the Swedish CArdioPulmonary bioImaging Study (SCAPIS) pilot cohort (n = 603, men 47.9%) underwent a submaximal cycle ergometer test for estimation of maximal oxygen consumption (VO2 max)...

Patients suffering from chronic kidney disease (CKD) are at a 20-fold higher risk of dying due to cardiovascular diseases (CVDs), primarily thrombosis following vascular injury. CKD is connected with retention of uremic toxins, especially indoxyl sulfate (IS), which are currently considered as a non-classical CKD-specific risk factor for CVDs. The present study aimed to examine the effect of chronic exposure to IS on the hemostatic system and arterial thrombosis in a model without greater interferences from the uremic milieu consisting of additional uremic toxins...

This study had two main objectives: To examine the association between body fat distribution and non-alcoholic fatty liver disease (NAFLD) and liver fat content, and to determine whether the relationship between NAFLD and regional body fat distribution, with respect to liver fat content in youths with excess adiposity, is independent of cardiorespiratory fitness (CRF) and a healthy diet. Liver fat content (controlled attenuation parameter (CAP)), body fat distribution (body mass index (BMI) z -score, waist circumference, waist-to-height ratio, fat mass/height, body fat percentage, total fat mass, android-to-gynoid fat mass ratio, visceral adipose tissue (VAT), and lean mass index, determined by dual-energy X-ray absorptiometry (DXA)), CRF (20-m shuttle-run test), and healthy diet (adherence to the Mediterranean diet by KIDMED questionnaire) were measured in 126 adolescents (66% girls) aged between 11 and 17 years...

BACKGROUND: The relationship between cardiorespiratory fitness (CRF) and mortality risk has typically been assessed using a single measurement, though some evidence suggests the change in CRF over time influences risk. This evidence is predominantly based on studies using estimated CRF (CRFe ). The strength of this relationship using change in directly measured CRF over time in apparently healthy men and women is not well understood. PURPOSE: To examine the association of change in CRF over time, measured using cardiopulmonary exercise testing (CPX), with all-cause and disease-specific mortality and to compare baseline and subsequent CRF measurements as predictors of all-cause mortality...

The purpose of this study was to identify which averaging methods most accurately measures peak cardiorespiratory fitness (CRF) parameters [peak O2 uptake (VO2 ), peak O2 pulse and peak respiratory exchange ratio (RER)] in a sample of healthy children and adolescents. In this cross-sectional multicenter study, we recruited 278 healthy children aged 12-17 years. We compared the mean peak value of three CRF parameters using the recommended averaging methods (30-second block average) with alternative averaging methods such as moving averages or shorter smoothing periods...

BACKGROUND: Literature shows that occurrence of comorbidities in people with severe acquired brain injury (sABI) is a common problem in rehabilitation stay. Consequently, patients could require an increase of interventions for diagnosis and treatment of clinical conditions, with a reduction of the rehabilitative take in charge for both clinical and organizational aspects. AIM: The first aim was to evaluate the rate of clinical conditions of sABI patients at admission in rehabilitation and the types of rehabilitative interventions performed in the first week; second objective was to explore the impact of clinical conditions on real rehabilitative take in charge...

Background: Physical fitness is an important index of health. Our aim was to assess whether cardiorespiratory and/or musculoskeletal components of physical fitness were associated with cardiometabolic risk clustering in obese youth, using adapted and validated field tests. Methods: We evaluated 252 children and adolescents (132 males, 120 females), mean age 10.9 ± 1.9 years with primary obesity. All subjects performed the six-minute walk test (6MWT) for assessing aerobic fitness, the standing broad jump, and the 30 s-chair stand tests for lower-body muscular strength, and the handgrip test for upper body isometric strength...

What is the central question of this study? Controlled-hyperthermia heat acclimation protocols induce an array of thermoregulatory and cardiovascular adaptations that facilitate exercise in hot conditions. We investigated whether this ergogenic potential can be transferred to thermoneutral normoxic or hypoxic exercising conditions. What is the main finding and its importance? We show that heat acclimation did not affect maximal cardiac output or maximal aerobic power in thermoneutral normoxic/hypoxic conditions...

Background: The use of short-acting anesthetics, muscle relaxation, and anesthesia depth monitoring allows maintaining sufficient anesthesia depth, fast recovery, and extubation of the patients in the operating room (OR). We evaluated the feasibility of extubation in the OR in cardiac surgery. Methods: This clinical trial was performed on 100 adult patients who underwent elective noncomplex cardiac surgery using cardiopulmonary bypass. Additional to the routine monitoring, the patients' depth of anesthesia and neuromuscular blocked were assessed by bispectral index and nerve stimulator, respectively...

PURPOSE OF REVIEW: Lung resection provides the best outcome for patients with early stage lung cancer. However, lung cancer surgery carries a significant risk of perioperative complications. Patient risk may be reduced by addressing modifiable risk factors in the preoperative period. We review how this can be achieved through preoperative rehabilitation pathways. RECENT FINDINGS: Cardiorespiratory fitness is an independent predictor of survival for nonsmall cell cancer...

PURPOSE: To describe cardiorespiratory, quadriceps oxygenation, and muscle fatigue responses during a one-legged quadriceps isokinetic endurance exercise in COPD and control subjects. METHODS: Fourteen patients with COPD and 14 control subjects performed a cardiopulmonary cycling exercise test (CPET) to exhaustion to assess peak oxygen consumption (V˙O2peak), minute ventilation (V˙E2peak) and heart rate (HRpeak). They also performed a quadriceps isokinetic endurance exercise consisting in 30 maximal knee-extensions at 90°/s with continuous monitoring of expired gases, cardiac output (CO) and oxygenation of the quadriceps by near-infrared spectroscopy...

INTRODUCTION: Multiple sclerosis(MS) is an immune-mediated, neurological disease that results in physiological deconditioning with increasing disability. High-intensity interval training exercise(HIIT) has induced significant improvements in physiological conditioning in healthy and clinical populations, and might be appropriate for persons with MS who have mobility disability. The feasibility and acute effects of HIIT using recumbent stepping in persons with MS who have mobility disability are relatively unknown...

The use of wearable devices in clinical routines could reduce healthcare costs and improve the quality of assessment in patients with chronic respiratory diseases. The purpose of this study is to evaluate the capacity of a Shimmer3 wearable device to extract reliable cardiorespiratory parameters from surface diaphragm electromyography (EMGdi). Twenty healthy volunteers underwent an incremental load respiratory test whilst EMGdi was recorded with a Shimmer3 wearable device (EMGdiW). Simultaneously, a second EMGdi (EMGdiL), inspiratory mouth pressure (Pmouth) and lead-I electrocardiogram (ECG) were recorded via a standard wired laboratory acquisition system...

Physical inactivity is strongly associated with an unfavorable health profile, increasing an individual's risk for developing cardiovascular disease. Initiating a regular exercise routine contributes to improvements in cardiorespiratory fitness, body composition, resting blood pressure, blood glucose, and circulating lipoproteins. However, the extent to which positive changes occur come with significant inter-individual variability within intervention groups; non-responders and responders have been commonly identified across populations, highlighting that not all exercise regimens are universally effective in all individuals and should therefore not be treated as a "one-size fits all" prescription...

OBJECTIVES: It is suggested that individuals will not reach their heart rate maximum (HRmax) at an incremental cardiorespiratory fitness (CRF) test and commonly five beats per minute (bpm) are added to the highest heart rate (HR) reached. To our knowledge, there is not sufficient data justifying such estimation. Our aim was to assess whether individuals reached HRmax in an incremental CRF test to exhaustion. DESIGN AND METHODS: Fifty-one males and 57 females (aged 22-70 years) completed both an incremental CRF test (gradual increase in speed and/or inclination until volitional exhaustion) and a test designed to reach HRmax (with repeated work bouts at high intensity before maximal exertion) ≥48h apart...
