Influence of hip external rotation on hip adductor and rectus femoris myoelectric activity during a dynamic parallel squat This study sought to compare the myoelectric activity of the hip adductors (HAs) and rectus femoris (RF) when the hip was in a neutral position or externally rotated by 30° or ...

One-set resistance training elevates energy expenditure for 72 h similar to three sets To compare the effects of an acute one versus three-set full body resistance training (RT) bout in eight overweight (mean ± SD, BMI = 25.6 ± 1.5 kg m(-2)) young (21.0 ± 1.5 years) adults on resting energy expendi...

Glucosamine but not ibuprofen alters cartilage turnover in osteoarthritis patients in response to physical training OBJECTIVE: To investigate changes in levels of serum cartilage oligomeric matrix protein (COMP) and urine c-telopeptide of type-2 collagen (CTX-II) as markers for cartilage turnover i...

Stance width and bar load effects on leg muscle activity during the parallel squat PURPOSE: Altering foot stance is often prescribed as a method of isolating muscles during the parallel squat. The purpose of this study was to compare activity in six muscles crossing the hip and/or knee joints when ...

A comparison of muscle activation between a Smith machine and free weight bench press The bench press exercise exists in multiple forms including the machine and free weight bench press. It is not clear though how each mode differs in its effect on muscle activation. The purpose of this study was t...

The effects of sprint running training on sloping surfaces The aim of this study was to examine the effects of sprint running training on sloping surfaces (3 degrees ) on selected kinematic and physiological variables. Thirty-five sport and physical education students were randomized into 4 trainin...

Effects of Low- vs. High-Load Resistance Training on Muscle Strength and Hypertrophy in Well-Trained Men The purpose of this study was to compare the effect of low- versus high-load resistance training (RT) on muscular adaptations in well-trained subjects. Eighteen young men experienced in RT were ...

Citrulline malate enhances athletic anaerobic performance and relieves muscle soreness The purpose of the present study was to determine the effects of a single dose of citrulline malate (CM) on the performance of flat barbell bench presses as an anaerobic exercise and in terms of decreasing muscle...

Body composition and strength changes in women with milk and resistance exercise PURPOSE: We aimed to determine whether women consuming fat-free milk versus isoenergetic carbohydrate after resistance exercise would see augmented gains in lean mass and reductions in fat mass similar to what we obser...

Ginger (Zingiber officinale) reduces muscle pain caused by eccentric exercise Ginger has been shown to exert anti-inflammatory effects in rodents, but its effect on human muscle pain is uncertain. Heat treatment of ginger has been suggested to enhance its hypoalgesic effects. The purpose of this st...

Gastric reacidification with betaine HCl in healthy volunteers with rabeprazole-induced hypochlorhydria Previous studies have demonstrated that increased gastric pH from the use of acid-reducing agents, such as proton-pump inhibitors or H2-receptor antagonists, can significantly impact the absorpti...

The effect of remote voluntary contractions on knee extensor torque PURPOSE: Concurrent activation potentiation (CAP) is purported to enhance the force capabilities of muscles via the contraction of muscles remote to the prime mover. This phenomenon has been described as remote voluntary contractio...

Reducing workplace burnout: the relative benefits of cardiovascular and resistance exercise Objectives The global burden of burnout cost is in excess of $300 billion annually. Locally, just under half of working Australians experience high levels of occupational burnout. Consequently, burnout inter...
