13. Estudo das alterações no volume muscular, na função articular e na marcha de hemiparéticos crônicos
This work consists of two studies. The aim of the first study was to investigate quadriceps and hamstring muscle volumes and strength deficits of the knee extensors and flexors in people with chronic hemiparesis compared to a healthy group. Fifteen individuals with chronic stroke and fifteen healthy individuals took part in this study. Motor function, quadri

14. Low-frequency fatigue at maximal and submaximal muscle contractions
Skeletal muscle force production following repetitive contractions is preferentially reduced when muscle is evaluated with low-frequency stimulation. This selective impairment in force generation is called low-frequency fatigue (LFF) and could be dependent on the contraction type. The purpose of this study was to compare LFF after concentric and eccentric ma

15. Correlação entre torque, equlíbrio e função do joelho após reconstrução do LCA
Background: Several studies emphasize the importance of assessing the knee function after anterior cruciate ligament (ACL) reconstruction. The influence of several variables on the function of these patients has been analyzed, but there is no consensus in the science literature. Purpose: To evaluate the correlation between the torque and balance on the knee

16. Desequilíbrio muscular e qualidade de vida de indivíduos com osteoartrite e artroplastia total de joelho
A osteoartrite de joelho caracteriza-se por um processo degenerativo da cartilagem articular e do osso subcondral, com a presença de processo inflamatório, dor, rigidez, fraqueza muscular, e que leva a uma incapacidade funcional. É uma doença degenerativa e incapacitante, e que necessita de reabilitação funcional para a melhora do indivíduo. Nos casos

17. Avaliação isocinética em pacientes submetidos à artroplastia por via de acesso transquadricipital e minimamente invasiva / Isokinetic evaluation in patients submitted to arthroplasty by the minimally invasive and transquadricipital approaches
INTRODUCTION: It has been stated that for total knee arthroplasty (TKA), the minimally invasive approach permits earlier rehabilitation because it is not prejudicial for the femoral quadriceps muscle. To verify the influence of preserving the extensor apparatus during surgery, strength of the knee extension and flexion muscles was evaluated in patients submi

18. Efeito agudo do alongamento estático dos isquiotibiais no desempenho isocinético dos músculos flexores e extensores de joelho
Stretching exercises are commonly prescribed before training sessions and competitions aiming at performance improvements and injury prevention. However, recent studies have shown that stretching may cause acute muscular torque production deficits. The physiological and biomechanical mechanisms underlying this behavior are not completely known. Moreover, the

19. Análise das correlaçõs entre as musculaturas periféricas e respiratórias com a capacidade funcional de idosos comunitários
Introduction: In older people, the reduced capacity of skeletal muscles to produce strength is related to loss of muscle mass, named sarcopenia. This could be present either in peripheral or respiratory muscles and it would impair functional capacity. The objectives of the present study were measure the strength of peripheral muscles (knee flexors and extens

20. Avaliação isocinetica de joelho em jogadores de futebol categoria sub-20
This research was subdivided in two distinct studies: study 1 - it had as objective to compare the isokinetic parameters of evaluation of the muscle flexor (F) and extensor (E) of knee as: peak of torque (PT), total work (TW), maximum power (MP) and index of fatigue (IF), as well as analyzing the differences of these isokinetic parameters between the members

21. Active stret ching program of the knee flexor muscle in a standing posture: effect on the ROM and muscle torque. / Alongamento ativo excêntrico dos músculos flexores do joelho na postura em pé: efeito sobre a amplitude de movimento e torque muscular.
A relação entre alterações na flexibilidade e torque muscular pósalongamentos tem sido pouco explorada pela literatura. São inúmeras as técnicas e posturas de alongamento sendo utilizadas tanto nas clínicas quanto em atividades esportivas. A técnica de alongamento ativo excêntrico realizada na postura em pé, com descarga de peso no membro alongad

22. Alterações funcionais e morfológicas do músculo quadríceps induzidas pelo treinamento excêntrico após reconstrução do LCA.
The anterior cruciate ligament (ACL) is the most commonly injured ligament in the knee and its rupture results in pain, instability, muscle atrophy and weakness. The quadriceps femoris muscle dysfunction is common before and after ACL reconstruction and can persist over years. A detailed understanding of neuromuscular function after ACL reconstruction is cri

23. Artificial gravity as a countermeasure to microgravity: a pilot study examining the effects on knee extensor and plantar flexor muscle groups
The goal of this project was to examine the effects of artificial gravity (AG) on skeletal muscle strength and key anabolic/catabolic markers known to regulate muscle mass. Two groups of subjects were selected for study: 1) a 21 day-bed rest (BR) group (n = 7) and 2) an AG group (n = 8), which was subjected to 21 days of 6° head-down tilt bed rest plus dail

24. In vivo strain of the medial vs. lateral quadriceps tendon in patellofemoral pain syndrome
Patellofemoral pain (PFP) is thought to be related to patellar maltracking due to imbalances in the knee extensor. However, no study has evaluated the in vivo biomechanical properties of the quadriceps tendon in PFP syndrome. Our purpose was to compare the biomechanical properties of the quadriceps tendons in vivo and noninvasively in patients with PFP syndr
