We sought to determine whether creatine monohydrate (CrM) supplementation would enhance the increases in strength and fat-free mass that develop during resistance exercise training in older adults. Twenty-eight healthy men and women over the age of 65 years participated in a whole-body resistance exercise program 3 days per week for 14 weeks. The study participants were randomly allocated, in a...

BACKGROUND Citrus flavonoids, such as hesperidin, have shown therapeutic properties that improve hyperglycemia and insulin resistance, and decrease blood serum lipids and inflammation. The current investigation studied the effects of hesperidin supplementation associated with continuous and interval swimming on the biochemical parameters (glucose, cholesterol and triglycerides), and oxidative s...

The origin of body surface P waves was evaluated in the intact dog by recording body surface isopotential maps and atrial epicardial potential maps. P waves were recorded from 150 points on the body surface, and 80 atrial unipolar electrograms were recorded by means of permanently implanted atrial electrodes during normal sinus rhythm and during atrial pacing. When the atrial pacing sites were ...

A measure of the absorption of elastic waves is the specific absorption coe•cient 1/Q. In dispersive mediums, whether the dispersion is due to geometry, inhomogeneity, or both, measurements are often made outside the body and the measurements must be interpreted as to the distribution of values of 1/Q within the body. Two definitive experiments of this type are those performed using standing wa...

Introduction: insulin resistance (IR) promotes the progression of fibrosis and diminishes response to treatment in patients with hepatitis C. Recently, Sydney’s index (includes IR) has been proposed as a non-invasive method for the prediction of fibrosis. Objective: to assess the usefulness of Sydney’s index for the prediction of advanced fibrosis (F3-F4) or absence of significant fibrosis (F0-...

It is unclear whether ethnic differences exist in adipose tissue (AT) and skeletal muscle (SM) distribution in black and white youth. Investigation into the pattern of AT and SM distribution in black versus white youth may provide insight into the previously reported health disparities between these ethnicities. Therefore, we examined total and regional AT and SM in overweight black and white b...

CONTEXT Dehydration is assumed to be a major adverse effect associated with rapid loss of body mass for competing in a lower weight class in combat sports. However, the effects of such weight cutting on body fluid balance in a real-life setting are unknown. OBJECTIVE To examine the effects of 5% or greater loss of body mass within a few days before competition on body water, blood volume, and...

In Part 11 of the study, the British Olympic track (sprint) squad cyclists demonstrated reductions in body fat index, % body fat and endomorphy (p > .05), increased Hb and PCV % (p > .05), and lowered HR at rest and in warm-up exercise (p > .05), but no change in leg power. Repeated interval sprints of short duration, maximal exercise on an "ergowheel" ergometer, at standardised power output, s...
