The Effect Of Eccentric And Concentric Training On The Size And Strength Of Human Skeletal Muscle, Haydn J. N. Mcdonald
The Effect Of Eccentric And Concentric Training On The Size And Strength Of Human Skeletal Muscle, Haydn J. N. Mcdonald
Theses : Honours
The objective of this study was to determine if the high forces generated through eccentric contractions, and the subsequent damage sustained, contributes to greater growth and force increase in human skeletal muscle than other contraction types, and whether damage from eccentric exercise effects the increase in torque and muscle size expected after a progressive concentric strength training program. 20 healthy subjects were split into four groups which participated in 3 different training protocols, with one group serving as the control (C). Groups underwent either concentric training (CT), eccentric damage (ED), or a combination of the two protocols (DC) with the …
Eccentrically Induced Skeletal Muscle Damage In Patients With Chronic Fatigue Syndrome (Cfs), With Reference To Overtrained Athletes, David L. Wright
Eccentrically Induced Skeletal Muscle Damage In Patients With Chronic Fatigue Syndrome (Cfs), With Reference To Overtrained Athletes, David L. Wright
Theses : Honours
Chronic fatigue syndrome (CFS) and Overtraining syndrome (OTS) are separate, complex conditions which have so many similar debilitating effects that it has led some researchers to conclude that OTS is a sub-condition of CFS. The purpose of this research was to compare the force and damage-recovery characteristics of skeletal muscle in CFS patients and control normals, after a single damaging bout of eccentric contractions in the non-dominant forearm flexors. The subjects ( n = 25 ), a convenience sample were assigned to three groups; [I] CFS + eccentric damage (n = 8), [2] Control Damage (CD)+ eccentric damage (n = …
Effect Of Exercise Induced Muscle Soreness On The Motor Control Properties Of The Biceps Brachii, Alan J. Pearce
Effect Of Exercise Induced Muscle Soreness On The Motor Control Properties Of The Biceps Brachii, Alan J. Pearce
Theses : Honours
The objective of this study was to note the time course changes for up to 28 days on the motor control properties of biceps brachii muscle following a bout of eccentric exercise. Eight subjects (5 male, 25-40 years of age) performed 35 maximal voluntary eccentric contractions with the non-preferred arm of the elbow flexors through 130° of extension of 90°s-1. Voluntary electromyographic (EMG) activity and motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) were recorded via surface electrodes placed over the belly of the biceps brachii muscle. Maximal isometric strength was measured at 90° elbow flexion. …
