STUDY DESIGN Cross-sectional study. OBJECTIVES To validate heart rate (HR) indexes for the evaluation of energy expenditure during wheelchair propulsion in people with spinal cord injury (SCI). SETTING SARAH Rehabilitation Hospital Network-Brasilia, Brazil. METHODS Forty-eight men aged 29.0±7.8 years with a SCI between C6 and L3 causing complete motor(More)
BACKGROUND Quantification of body composition variables is important for planning of better activities in relation to individuals with spinal cord injury (SCI). OBJECTIVES (1) To evaluate changes in body composition in patients with SCI after a supervised physical activity process; (2) To correlate total body fat with time since injury. DESIGN Pre-post(More)
STUDY DESIGN This was a retrospective observational study. OBJECTIVE The objective was to determine the normative values for 20 min exercise of wheelchair propulsion in spinal cord injury (SCI) subjects. SETTING Sarah Rehabilitation Hospitals Network, Brazil. METHODS A total of 413 medical records for SCI patients at different levels and(More)
INTRODUCTION Investigations on the effects of KT on human performance have been increasing in the last few years. However, there is a paucity of studies investigating its effects on neuromuscular efficiency (NME) and rate of force development (RFD). OBJECTIVE To evaluate the NME and RFD of the soleus and gastrocnemius muscles in physically active(More)
Physical inactivity is considered a risk factor for cardiovascular disease and is strongly associated with changes in arterial structure. Regular physical activity and exercise contributes to the prevention of coronary artery disease. Therefore, cardiovascular and resistance training improve hemostatic parameters and promote a less thrombotic blood profile.(More)
INTRODUCTION Hypertension is the most prevalent modifiable risk factor with a high prevalence among older adults. Exercise is a nonpharmacological treatment shown to benefit all patients with hypertension. OBJECTIVE This study examined the effects of a 14-week moderate intensity resistance training program (RT) on the maintenance of blood pressure and(More)
STUDY DESIGN Cross-sectional study. OBJECTIVES To measure the reproducibility and responsiveness of heart rate indexes in measuring energy expenditure during wheelchair locomotion of adults with spinal cord injury (SCI). SETTING SARAH Rehabilitation Hospital Network-Brasilia, Brazil. METHODS The study consecutively enrolled 35 individuals with SCI.(More)
