Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Theses : Honours
Investigations into the mediators of effort sensation have indicated that central mechanisms related to corollary discharges may be responsible for an increased sense of effort during fatiguing isometric exercise. The role for central mediators for sense of effort have been objectively demonstrated through use of contralateral limb matching tasks. Subjects diagnosed with chronic fatigue syndrome (CFS) often report prevalent fatigue associated with a greater sense of effort when involved in exercise. This study employed a fatiguing contralateral limb-matching task in order to determine if CFS subjects (n == 6) experienced an altered sense of effort associated with the task when …
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. …
