Determination of the lactate threshold and maximal blood lactate steady state intensity in aged rats
(Cell Biochemistry and Function, 2009-08-01) [Artigo]
The reliability of the lactate threshold (LT) determined in aged rats and its, validity to identify an exercise intensity corresponding to the maximal blood lactate steady state (MLSS) were analyzed. Eighteen male aged ...
Heavy-intensity aerobic exercise affects the isokinetic torque and functional but not conventional hamstrings:quadriceps ratios
(Journal of Electromyography and Kinesiology, 2009-12-01) [Artigo]
Running exercises are frequently related to muscular injuries, which may be a result of muscular imbalance. The present study aimed to verify the effects of heavy-intensity continuous running exercise on the functional and ...
Influence of Imposed Optic Flow Characteristics and Intention on Postural Responses
(Motor Control, 2009-04-01) [Artigo]
This study examined the influence of both optic flow characteristics and intention on postural control responses. Two groups of 10 adults each were exposed to the room's movement either at 0.6 cm/s (low velocity group) or ...
Exercise test and glucose homeostasis in rats treated with alloxan during the neonatal period or fed a high calorie diet
(Journal of Diabetes, 2009-03-01) [Artigo]
Background: Animal models appear well-suited for studies into the role of exercise in the prevention of non-insulin-dependent diabetes mellitus (NIDDM). The aim of the present study was to analyze glucose homeostasis and ...
Back to school with tablets embedded in digital desks
(Information Display, 2009-09-01) [Artigo]
A digital-desk pilot program, named One Laptop Per Child (OPLC), in Brazil uses a unique display design to provide an interactive interface developed to enhance education and minimize ergonomic concerns. The one-to-one ...
Effect of 6-months of physical exercise on the nitrate/nitrite levels in hypertensive postmenopausal women
(BMC Women's Health, 2009-06-19) [Artigo]
Background: Evidences have showed that the incidence of arterial hypertension is greater in postmenopausal women as compared to premenopausal. Physical inactivity has been implicated as a major contributor to weight gain ...
Exercise programs improve mobility and balance in people with Parkinson's disease
(Parkinsonism & Related Disorders, 2009-12-01) [Artigo]
Compromised balance and loss of mobility are among the major consequences of Parkinson's disease (PD). The literature documents numerous effective interventions for improving balance and mobility. The purpose of this study ...
Oxidative Stress Impairs Vasorelaxation Induced by the Soluble Guanylyl Cyclase Activator BAY 41-2272 in Spontaneously Hypertensive Rats
(American Journal of Hypertension, 2009-05-01) [Artigo]
BACKGROUNDBAY 41-2272 (5-cyclopropyl-2-(1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-pyrimidin-4-ylamine) relaxes mesenteric arteries (MA) in a synergistic fashion with nitric oxide (NO). We hypothesized that the ...
Effects of Exercise Mode on the Oxygen Uptake Kinetic Response to Severe-Intensity Exercise in Prepubertal Children
(Pediatric Exercise Science, 2009-05-01) [Artigo]
The objective of this study was to verify the effect of the exercise mode on slow component of VO(2) (VO(2)SC) in children aged 11-12 years during severe-intensity exercise. After determination of the lactate threshold ...
Effects of postural threat on walking features of Parkinson's disease patients
(Neuroscience Letters, 2009-03-13) [Artigo]
This study investigated whether or not gait kinematics among healthy older individuals and Parkinson's disease (PD) patients are influenced by postural threat. Eight healthy older individuals and eight PD patients were ...
