The effects of N-acetylcysteine infusion on performance, glutathione and ion regulation during voluntary exercise in humans
… in skeletal muscle has been linked with muscle fatigue. Infusion of the antioxidant compound 7V-acetylcysteine (NAC) reduced fatigability in electrically evoked human muscle contractions, but numerous adverse reactions were reported. No studies have investigated NAC infusion effects during …

Effects of Tool Weight on Fatigue and Performance During Short Cycle Overhead Work Operations
… a larger body of research that examined shoulder time to fatigue during overhead work in an attempt to reduce the prevalence and impact of work-related musculoskeletal problems in the shoulder associated with overhead work, particularly during automobile assembly. Existing evidence suggests that …

Oxygen Uptake Kinetics in Severe Intensity Exercise
The purpose of this study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit …

Nitrogen Metabolites During Exercise in the Horse
… Horse mares were intravenously infused prior to exercise with either sodium acetate (control) or ammonium acetate to determine the effect of elevated ammonia (NH$\sb3$) levels on fatigue development and muscle metabolism. The horses were exercised on an 11% grade treadmill at 4.4 m/s, carrying …

MUSCLE FATIGUE ANALYSIS IN MINIMALLY INVASIVE SURGERY
Due to its inherent complexity such as limited work volume and degree of freedom, minimally invasive surgery (MIS) is ergonomically challenging to surgeons than traditional open surgery. Specifically, MIS can expose performing surgeons to excessive ergonomic risks including muscle fatigue that may …

Potential adaptive signaling pathways in the diaphragm of mdx mice treated with micro-dystrophin combined with voluntary running
… voluntary wheel running (R) was complementary to micro-dystrophin gene therapy (GT) in mdx mice, a model of Duchenne muscular dystrophy (DMD). After 21 weeks of running, time to fatigue on a treadmill for the mdxRGT mice was increased 1.8-fold compared to mdxGT mice (no run) and ~5-fold …

Physiological adaptations in mdx mice treated with microdystrophin gene therapy and endurance exercise
… progressive muscle weakness and susceptibility to damage. DMD is caused by a lack of dystrophin, a large muscle protein that performs both structural and signaling functions. A promising treatment currently in clinical trials is microdystrophin gene therapy, which delivers a truncated version of …

The effects of amlodipine on exercise performance in mild to moderate essential hypertensives
… patients is not known. The aim of this study was to determine the effects of amlodipine on maximal (MAX), prolonged submaximal (PSX) and on skeletal muscle function (SMF) in patients with mild hypertension. In a double-blind randomised crossover trial, ten physically active hypertensive patients …

The effects of acute dehydration of 5% body mass on performance and physiology of mixed martial arts athletes
… Arts (MMA) athletes are weighed 24 h prior to competition. In order to compete in a lower weight class MMA athletes will often rapidly lose weight via dehydration. Despite the prevalence, there is currently no known published data examining the effects of acute dehydration on physiology and …

Selected exercise and skeletal muscle characteristics of African distance runners
… Therefore, the aim of this thesis was to compare selected exercise and skeletal muscle characteristics in well-trained African and Caucasian 10 km runners to determine if evidence exists of differences between these groups with respect to these physiological and biochemical …

Exercise tolerance and skeletal muscle structure and function in patients with severe chronic heart failure
Fatigue and exercise intolerance are common symptoms experienced by patients with chronic heart failure (CHF). Historically it has been argued that central cardiopulmonary factors including pulmonary congestion and reduced lung compliance cause dyspnoea that limits the exercise tolerance of such …

A.P. Giannini, Marriner Stoddard Eccles, and the Changing Landscape of American Banking
… Federal Reserve System in 1913 was insufficient to correct flaws in the banking system until the Banking Acts of 1933 and 1935. A.P. Giannini, the American-Italian founder of the Bank of America and Mormon Marriner S. Eccles, chairman of Federal Reserve Board (1935-1949), from California and Utah …

Digoxin and exercise effects on Na+,K+-ATPase isoform gene and protein expression in human skeletal muscle
This laboratory has shown that exercise in humans impairs skeletal muscle Na+,K+-ATPase maximal in vitro activity, whilst in isolated rat muscles, Na+,K+-ATPase inhibition with ouabain leads to early muscle fatigue. Hence, Na+,K+-ATPase function is likely to be important for skeletal muscle …
