1. Oxygen consumption and heart rate obtained in a ramp protocol are equivalent during exercise session of rectangular loading at ventilatory thresholds for athletes
Resumo O treinamento no limiar ventilatório (LV) é um estímulo adequado para melhorar os limiares em indivíduos sedentários, entretanto uma maior intensidade é necessária para indivíduos condicionados. A escolha do protocolo de teste de exercício cardiopulmonar (CPx) tem influência na identificação dos LV e pode reduzir sua confiabilidade na pres

2. Evaluation of anaerobic threshold in non-pregnant and pregnant rats
ABSTRACT Several studies present different methodologies and results about intensity exercise, and many of them are performed in male rats. However, the impact of different type, intensity, frequency and duration of exercise on female rats needs more investigation. From the analysis of blood lactate concentration during lactate minimum test (LacMin) in the s

3. Biomechanical Parameters in Children with Unilateral and Bilateral Clubfoot during Vertical Jumps
Abstract Gait analysis may offer information to choose the best exercise-based clinical intervention for the children with clubfoot. However, other motor abilities are not commonly investigated. The aim of this research was to analyze the biomechanics of countermovement vertical jumping in clubfooted children who had undergone surgery. Fourteen children with

4. The effect of acute magnesium loading on the maximal exercise performance of stable chronic obstructive pulmonary disease patients
OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stabl

5. Efeitos da suplementação de zinco e do treinamento físico sobre o metabolismo e a densidade óssea de ratas ovariectomizadas
Osteoporosis is a serious public health problem, and increasingly is recognized as a disease limiting quality of life, especially for the elderly. The role of zinc in human nutrition has been extensively studied. Several hormones and zinc-dependent enzymes are involved in bone metabolism. Physical activity has been advocated as a means to increase and mainta

6. Efeito do decanoato de nandrolona associado ao exercício de carga na expressão do fator de crescimento de endotélio vascular (VEGF) no músculo sóleo de ratos
Muitos estudos vêm mostrando os efeitos nocivos para o organismo do abuso de esteróides anabólicos androgênicos (EAA) por atletas e freqüentadores de academia. Entretanto há poucas pesquisas relatando os efeitos prejudiciais dessas substâncias no músculo esquelético. O objetivo desse trabalho foi analisar a expressão do fator de crescimento de endo

7. Um software educativo de exercÃcio-e-prÃtica como ferramenta no processo de alfabetizaÃÃo infantil / An educational exercise and practice software used as a tool in the process of child literacy
There exists a growing concern among educators when it comes to the use of new information and communication technologies (ICTâs) in the practical day-to-day contact with students. Through its low cost and public policy rules, the computer has shown itself to be a means by which this proposal could be realized. Therefore the objective has been the developme

8. Role of aortic input impedance in the decreased cardiovascular response to exercise with aging in dogs.
The diminished cardiac output response to exercise with advancing age may be attributable to intrinsic inability of the old ventricle to respond appropriately and/or to an additional loading imposed upon the ventricle by the aged vascular system. The steady (resistance) and pulsatile (characteristic impedance) load components together comprise the vascular l

9. Effect of mitral valve replacement on left ventricular function in mitral regurgitation.
To evaluate the effect of mitral valve replacement on left ventricular function in mitral regurgitation, we measured (1) the end-systolic stress/volume ratio, which is practically independent of changes in loading conditions, and (2) the left ventricular contractile reserves upon isometric exercise, both before and one year after mitral valve replacement in

10. Exercise increases osteophyte formation and diminishes fibrillation following chemically induced articular cartilage injury.
The present study shows that a treadmill exercise regimen imposed on guinea-pigs whose articular cartilage has been damaged by intra-articular injection of IA reduces chondrocyte depletion, results in an increase in pericellular Safranin-O staining around surviving chondrocytes, and prevents fibrillation of the articular surface. The data suggest that exerci

11. Physical activity at leisure and risk of osteoarthritis.
A summary of the evidence linking exercise and osteoarthritis is given in the table. In summary, normal joints appear to tolerate prolonged vigorous low impact exercise without accelerated development of osteoarthritis. The risk of developing osteoarthritis appears to be increased in sporting activities that continually expose normal joints to high levels of

12. In situ microdialysis in bone tissue. Stimulation of prostaglandin E2 release by weight-bearing mechanical loading.
In this study we describe, to our knowledge, the first experiment using the microdialysis technique for studying the release of prostaglandin E2 (PGE2) in the proximal tibia metaphysis secondary to mechanical loading. Nine healthy females, six in the loading group and three controls, mean age 34+/-2 (years+/-SEM), participated. A standard microdialysis cathe
