A fitness index model for Italian adolescents living in Southern Italy. The ASSO project
2016
BACKGROUND: Strong relations between physical fitness and health in adolescents have been established in the last decades. The main objectives of the present investigation were to assess major physical fitness components in a sample of Italian school adolescents, comparing them with international data, and providing a Fitness Index model derived from percentile cut-off values of five considered physical fitness components. METHODS: A total of 644 school pupils (15.9�1.1 years; M: N.=399; F: N.=245) were tested using the ASSO-Fitness Test Battery (FTB), a tool developed within the Adolescents and Surveillance System for the Obesity prevention project, which included the handgrip, standing br…
Concurrent and construct validation of a new scale for rating perceived exertion during elastic resistance training in the elderly
2020
Purpose:\ud To examine the concurrent and construct validity of a new perceptual scale to control the exercise intensity using elastic bands (Resistance Intensity Scale for Exercise; RISE) in the elderly.\ud \ud Methods:\ud Twenty-six participants underwent two sessions consisting of 4 exercises. The participants performed three sets of 15 repetitions per exercise of either low, medium, or high intensity. The criterion variables were heart rate and applied force (mean and peak). Following the final repetition of each set, active muscle (AM) and overall body (OB) ratings of perceived exertion (RPE) were collected from RISE and the OMNI-Resistance Exercise Scale of perceived exertion with ela…
Exercise stress CMR reveals reduced aortic distensibility and impaired right-ventricular adaptation to exercise in patients with repaired tetralogy o…
2018
International audience; The aim of our study was to evaluate the feasibility of exercise cardiac magnetic resonance (CMR) in patients with repaired tetralogy of Fallot (RTOF) and to assess right and left ventricular adaptation and aortic wall response to exercise in comparison with volunteers.Methods11 RTOF and 11 volunteers underwent prospective CMR at rest and during exercise. A supine bicycle ergometer was employed to reach twice the resting heart rate during continuous exercise, blood pressure and heart rate were recorded. Bi-ventricular parameters and aortic stiffness were assessed using accelerated cine sequences and flow-encoding CMR. A t-test was used to compare values between group…
Associations of fitness, motor competence, and adiposity with the indicators of physical activity intensity during different physical activities in c…
2021
We investigated the associations of peak oxygen uptake (V̇O2peak), ventilatory threshold (VT), muscle strength, motor competence (MC), and adiposity with the indicators of PA intensity during different physical activities used to create absolute PA intensity cut-offs among 35 children 7–11-years-of-age. V̇O2peak was defined as the highest V̇O2 achieved in the maximal cardiopulmonary exercise test (CPET) on a cycle ergometer, self-paced running, or running on a treadmill at 8 km/h. VT was defined from the CPET data. Peak isometric knee extensor and flexor strength was assessed by a dynamometer, MC by the Körperkoordination test für Kinder tests, and body composition by the bioelectrical impe…
Force-velocity profiling in athletes: Reliability and agreement across methods
2021
The aim of the study was to examine the test-retest reliability and agreement across methods for assessing individual force-velocity (FV) profiles of the lower limbs in athletes. Using a multicenter approach, 27 male athletes completed all measurements for the main analysis, with up to 82 male and female athletes on some measurements. The athletes were tested twice before and twice after a 2- to 6-month period of regular training and sport participation. The double testing sessions were separated by ~1 week. Individual FV-profiles were acquired from incremental loading protocols in squat jump (SJ), countermovement jump (CMJ) and leg press. A force plate, linear encoder and a flight time cal…
Noninvasive Ventilatory Assistance During Exercise for Patients with Kyphoscoliosis
2007
The goal was to determine whether noninvasive ventilatory assistance (NIV) could facilitate exercise performance and benefit physiologic parameters for eight hypercapnic kyphoscoliosis patients using a cycloergometer for 6-min periods at a constant power (20 W). The exercise protocols were performed in random order while breathing unaided (spontaneous breathing test or SBT) and also while receiving NIV (NIV test or NIVT). The NIV was pressure support (15 cm H2O) plus positive end expiratory pressure (PEEP) (4 cm H2O) via a nasal mask. Of the compared parameters, heart rate was not significantly different, but acidosis (pH = 7.32 +/- 0.04 vs. 7.36 +/- 0.04), hypoxia (PaO2 = 61.5 +/- 15.9 vs.…
Delayed Anaerobic Threshold in Heart Failure Patients With Atrial Fibrillation
2016
PURPOSE To assess whether atrial fibrillation (AF) in heart failure (HF) affects oxygen uptake at anaerobic threshold ((Equation is included in full-text article.)O2 AT) and heart rate (HR) kinetics. METHODS A total of 15 patients with HF and AF and 18 with HF and sinus rhythm (SR) performed a maximal incremental and 2 constant workload cycle ergometer cardiopulmonary exercise tests (below and above AT, at 25% and 75% of maximal workload, respectively). At constant workload tests, kinetics of (Equation is included in full-text article.)O2 and HR were assessed by calculating time constant (τ). RESULTS HF patients with AF showed a similar peak (Equation is included in full-text article.)O2 to…
Impact of moderate ischemic mitral regurgitation after isolated coronary artery bypass grafting
2009
The aim of the study was to evaluate the clinical and echocardiographic outcomes, at rest and under exercise testing, of patients with moderate ischemic mitral regurgitation (IMR) undergoing isolated coronary artery bypass graft surgery (CABG).Between February 2003 and March 2008, 180 patients with moderate IMR who had isolated CABG were enrolled. Patients were matched 1:2 (n = 360) with patients who underwent isolated CABG without IMR (by propensity score). The study endpoints were freedom from all death, cardiac related-death, late events, and cardiac-related events. Late outcomes and left ventricular remodeling were evaluated according to preoperative percent of ejection fraction. Sympto…
Arterial Stiffness is Related to Impaired Exercise Capacity in Patients With Coronary Artery Disease and History of Myocardial Infarction
2018
Background Augmented arterial stiffness and reduced cardiorespiratory fitness are associated with increased morbidity and mortality from coronary artery disease (CAD). The relationship between exercise capacity and arterial stiffness is independent of known influencing variables in CAD. This study aimed to analyse the interaction between exercise capacity, arterial stiffness and early vascular ageing in patients with CAD. Methods This cross-sectional study included 96 CAD patients with myocardial infarction (55.9 ± 10.9 years, 81 men) referred to cardiac rehabilitation. Arterial stiffness was assessed using carotid-femoral pulse wave velocity (cf-PWV). Cardiopulmonary exercise test was perf…
Motor Competence and Health-related Fitness of School-Age Children: A Two-Year Latent Transition Analysis
2021
PURPOSE The aims of this study were twofold: 1) to identify latent physical performance profiles of motor competence (MC) and cardiorespiratory (CF) and muscular fitness (MF) among school-age children and 2) explore transition probabilities in physical performance profiles over a 2-yr period. METHODS The present sample comprised 1148 (583 girls, 565 boys) elementary school students (baseline Mage = 11.27 ± 0.32), and data were collected annually (equal intervals) over a period of 2 yr which resulted in a total of three measurements. The measures used were the throwing-catching combination test, 5-leaps and two-legged jumps from side-to-side test (MC), 20-meter shuttle run test (CF), and cur…
