1. EFFECTS OF TRAINING LOAD CHANGES ON PHYSICAL PERFORMANCE AND EXERCISE-INDUCED MUSCLE DAMAGE
RESUMO Introdução Não existe nenhum estudo anterior que tenha analisado as respostas às lesões musculares decorrentes das alterações da carga de treinamento em indivíduos treinados exclusivamente com exercícios repetitivos de corrida. Objetivos A proposta deste estudo foi examinar o efeito das alterações da carga de treinamento sobre o desempe

2. Exercício resistido no cardiopata: revisão sistemática
INTRODUÇÃO: A perda de massa muscular secundária à idade e à inatividade física é clinicamente relevante na população cardíaca; contudo, a prescrição do exercício resistido dinâmico para esses pacientes apresenta-se inconclusiva na literatura. OBJETIVOS: Reunir informações e apresentar as principais diretrizes relacionadas à prescrição de

3. Proposta Metodológica Para Avaliação Quantitativa da Fase Rápida da Curva Força-Tempo na Preensão Manual de Pacientes com Doença Renal Crônica / Methodological proposal for quantitative assessment of the fast phase of the handgrip force-time curve with chronic kidney disease patients.
A Doença Renal Crônica (DRC) é caracterizada pela perda da capacidade de filtragem dos rins. O paciente com DRC tem diminuição dos níveis de força muscular e de condicionamento físico, os quais estão diretamente ligados à qualidade de vida e à realização das atividades da vida diária. A atividade física, especificamente o treinamento de força

4. ProspecÃÃo do estoque de robalo-peva (Centropomus parallelus) no litoral do ParanÃ, atravÃs da pesca esportiva / Prospecting of the stock of bass-peva (Centropomus parallelus) on the Parana coast, through the sport fishing
The snooks are fishes very appreciated food item by fish consumers and recreational fishermen, for they are endowed with a high quality flesh and put up a fierce fight when captured with line-and-hook. Such characteristics make this taxon a target for a host of users, objectives and needs (commercial and recreational fishing) which, together with loss of hab

5. Estudo eletromiografico da influencia dos musculos biceps e triceps do braço e braquiorradial, nas diferentes posições articulares do ombro
The purpose of this study was to analyze the influence of biceps raquialis, braquiorradial, and triceps braquialis on the flexon activity at different positions of the shoulder joint. It was observed the isometric semipronate elbow flexion contractions with anatomical position of the shoulder, 90° shoulder flexion and 90s houder abduction. Ten healthy femal

6. Plasma noradrenaline concentrations during isometric exercise.
Blood was collected simultaneously from the left ventricle and pulmonary artery in 12 patients undergoing routine cardiac catheterisation and was analysed for noradrenaline concentrations at rest, during, and after isometric stress (hand grip). Moderate isometric exercise resulted in a significant rise in plasma noradrenaline with a return to basal values 10

7. Effect of muscle mass on the pressor response in man during isometric contractions.
1. Changes in blood pressure and heart rate were measured in six healthy male subjects during voluntary isometric contractions of the forearm and quadriceps muscles. Arterial pressure was measured directly via a catheter inserted into the radial artery of the non-contracting arm. Each subject exerted two types of contractions: (a) sustained contractions at 7

8. An evaluation of the dynamic qualities of isometric grip strength.
A strain gauged torsion dynamometer linked to a microprocessor was used to assess the dynamic qualities of isometric grip strength in patients with rheumatic diseases. Maximum grip strength, time to maximum grip, and percentage fatigue provide independent information on the grip. Time to maximum grip does not appear to be an objective correlate of subjective

9. Influence of force on muscle and skin sympathetic nerve activity during sustained isometric contractions in humans.
1. Our purpose was to test the hypothesis that efferent sympathetic nerve activity to non-active skeletal muscle (MSNA) and skin (SSNA) is independent of the level of force during sustained submaximal isometric contractions in humans. 2. In twelve healthy subjects, arterial blood pressure, heart rate, and MSNA (n = 6) or SSNA (n = 6) (peroneal microneurograp

10. Cardiovascular responses to static exercise in man: central and reflex contributions.
1. To assess the contributions of muscle chemoreflexes and central signals of motor command to cardiovascular to static exercise, blood pressure and heart rate were measured during three separate conditions: (i) isometric handgrip contractions, (ii) entrapment of metabolites produced by these contractions within the contracting muscles (chemoreflex effect),

11. Exercise performance and fatiguability in patients with chronic fatigue syndrome.
To examine the role of delay in recovery of peripheral muscle function following exercise in the fatigue experienced by patients with the chronic fatigue syndrome (CFS) and to examine the influence of effort perception in limiting exercise performance in these patients, a study was carried out on a group of twelve patients with chronic fatigue syndrome and 1

12. Position sense and state of contraction; the effects of vibration
The position sense of the knee joint was investigated in normal subjects lying in the supine position with both legs hanging freely. Three different manoeuvres were used to bring one leg into an extended position: voluntary activation of the quadriceps muscle, reflex activation of the quadriceps (TVR) and passive lifting of the leg. For each manoeuvre the su
