This study assessed clinical and cardiorespiratory responses after an interval training programme in sedentary elderly adults using the ventilatory threshold (V th) as the index of exercise training intensity. A selection of 22 subjects were randomized into two groups: 11 subjects served as the training group (TG) and the others as controls (CG). Maximal(More)
BACKGROUND Research on cardiac rehabilitation has raised interesting methods and effects without however establishing the share of the profits according to age, sex and cardiac pathology. Yet today, this disease with various pathologies strikes people of all ages and both sexes, and the recommended rehabilitation exercise intensity is often the ventilatory(More)
The purpose of this study was to assess whether obesity induces changes in breathing pattern and ventilatory neural drive and mechanics. Measurements performed in 34 male obese subjects (BMI, 39+/-6 kg/m(2)) and 18 controls (BMI, 23+/-3 kg/m(2)) included anthropometric parameters, spirometry, breathing patterns, mouth occlusion pressure, maximal inspiratory(More)
OBJECTIVES To measure the cardiorespiratory requirements of the six-minute walk test (6MWT), to compare this demand with the symptom-limited exercise test (SLET) at ventilatory threshold and at maximal level in elderly patients with coronary artery disease (CAD), and to assess the reproducibility of the 6MWT in cardiorespiratory exchanges in those patients.(More)
OBJECTIVE To evaluate whether using surface electromyography to assess skeletal muscle fatigue during an isometric exercise has the potential to be clinically useful in patients with coronary artery disease (CAD). DESIGN Double sample comparative study. SETTING Cardiac rehabilitation service in France. PARTICIPANTS Sixteen men with documented CAD and(More)
Objective:The aim of this study was to assess overall inspiratory muscle activity during incremental exercise in obese men and healthy controls using the non-invasive, inspiratory muscle tension–time index (TT0.1). We studied 17 obese subjects (mean age±s.d.; 49±13 years) and 14 control subjects (42±16) during an incremental, maximal exercise(More)
OBJECTIVE:The aim of this study was to investigate the effect of excessive mechanical load caused by obesity on the inspiratory muscle performance in obese men at rest.METHODS:We therefore measure at rest spirometric flows and the noninvasive tension time index of inspiratory muscle (T Tmus=P I/P Imax × T I/T TOT) in eight obese male subjects (body mass(More)
The aim of this study was to determine if the diminished aerobic capacity of coronary artery disease male (CAD) patients is accompanied by an impaired skeletal muscle function compared to healthy control subjects. Thirteen CAD patients and 9 healthy subjects performed both a maximal laboratory exercise testing and an assessment of the peripheral skeletal(More)
The aim of this study was to compare the inspiratory muscle performance during an incremental exercise of twelve fit old endurance-trained athletes (OT) with that of fit young athletes (YT) and healthy age-matched controls (OC). The tension-time index (TT0.1) was determined according to the equation TT0.1=P0.1/PImax×ti/ttot, where P0.1 is the mouth(More)
The aim of this study was to investigate the effects of aging on athletes' cardiorespiratory responses to a brief intense intermittent effort, using the force-velocity test as an exercise model. Twelve young athletes (24.8 +/- 1.3 years) and twelve master athletes (65.1 +/- 1.2 years) with similar heights, body masses, and endurance training schedules(More)
