Changes in the force-frequency relationship of the human quadriceps femoris muscle following electrically and voluntarily induced fatigue.
The purpose of this study was to identify the changes in the force-frequency relationship (FFR) of the human quadriceps femoris muscle following electrically and voluntarily induced fatigue. Twenty nondisabled subjects each participated in one experimental session to test the effects of electrically induced fatigue on the FFR; 10 of these subjects participated in a second session in which volun...
متن کاملEffects of length on the catchlike property of human quadriceps femoris muscle.
BACKGROUND AND PURPOSE Recent reports have suggested that electrical stimulation trains that take advantage of the catchlike property of skeletal muscle can produce higher forces from skeletal muscle than traditionally used constant-frequency trains. This study investigated the effects of catchlike-inducing trains on human quadriceps femoris muscles while the kneejoint was held at 15 degrees of...
متن کاملStrength changes in the normal quadriceps femoris muscle as a result of electrical stimulation.
The purpose of this study was to examine the effectiveness of an electronic muscle stimulator in strengthening normal quadriceps femoris muscle without the assistance of simultaneous isometric muscle contraction. The sample consisted of 58 subjects who were randomly divided into three independent groups. One group (n = 19) served as controls; one group (n = 20) underwent daily stimulation of th...

Introduction: Electrical stimulation has been used for many years in rehabilitation medicine to prevent atrophy or to increase muscle strength, but the use of electrical stimulation for muscle strengthening in research and clinical practice has become increasingly popular in recent years. The quadriceps femoris is the thigh muscle group that suffers the greatest amount of atrophy. This study ai...
متن کاملEffects of activation frequency and force on low-frequency fatigue in human skeletal muscle.
No comparison of the amount of low-frequency fatigue (LFF) produced by different activation frequencies exists, although frequencies ranging from 10 to 100 Hz have been used to induce LFF. The quadriceps femoris of 11 healthy subjects were tested in 5 separate sessions. In each session, the force-generating ability of the muscle was tested before and after fatigue and at 2, approximately 13, an...
