Does the incremental shuttle walk test require maximal effort in young obese women?

Braz. j. med. biol. res; 49 (8), 2016
Obesity is a chronic disease with a multifaceted treatment approach that includes nutritional counseling, structured exercise training, and increased daily physical activity. Increased body mass elicits higher cardiovascular, ventilatory and metabolic demands to varying degrees during exercise. With func...

Interval training based on ventilatory anaerobic threshold increases cardiac vagal modulation and decreases high-sensitivity c-reative protein: randomized clinical trial in coronary artery disease

Background: Autonomic dysfunction and inflammatory activity are involved in the development and progression of coronary artery disease (CAD), and exercise training has been shown to confer a cardiovascular benefit. Objective: To evaluate the effects that interval training (IT) based on ventilatory anaero...

Assessment of intensity effort of middle-aged adults practicing regular walking

Background: Walking is one of the most commonly recommended activities for sedentary individuals. When performed at the correct intensity, it can provide cardiovascular, respiratory, metabolic, and other benefits by providing a training effect in addition to reducing the risk of death from cardiovascular...

Effects of high altitude on morphophysiological patterns, perception and attention capacity in students from Putre (3500 m. a. s. l. ) and Arica (2 m. a. s. l. ), Chile

Int. j. morphol; 32 (2), 2014
High altitude hypoxia is a stress that triggers several adaptive mechanisms, one of which is how the brain responds to lack of oxygen. The aim of this study was to determine changes in morphological and physiological patterns and in the attention capacity and perception in student populations from the hi...

Test de caminata de seis minutos y función pulmonar en pacientes con bronquiolitis obliterante post infecciosa

Introduction: Post-infectious bronchiolitis obliterans (BO) is a chronic respiratory disease that is established as a consequence of a lung infection produced by adenovirus. The clinical and radiological evidence as well as spirometric variables are the cornerstones of diagnosis; however, the functional ...

Reflexo dos barorreceptores e homeostase da pressão arterial
Baroreflexes and blood pressure homeostasis

A hipertensão arterial é considerada um dos principais fatores de risco para a morbidade e mortalidade cardiovascular. Os reflexos originados nos barorreceptores arteriais e nos receptores de estiramento da região cardiopulmonar são os principais mecanismos de controle efetivo da pressão arterial a ...
