Changes in body composition in patients with left ventricular systolic dysfunction initiated on beta-blocker therapy.

Background: Increasing body mass index, cholesterol and body fat are associated with a better prognosis in patients with left ventricular systolic dysfunction (LVSD). Beta-blocker usage is associated with changes in body composition and increased body fat. The present study investigated 12-month changes in body composition in patients with LVSD initiated on beta-blocker therapy.

The lived experiences of people diagnosed with multiple sclerosis in relation to exercise.

The purpose of this study was to examine the lived experiences of people diagnosed with Multiple Sclerosis (MS). Seven active exercisers with MS participated in semi-structured interviews regarding their exercise experiences since diagnosis. Data were analysed using Interpretative Phenomenological Analysis (IPA; Smith  & Osborn, 2003 ).

Prognostic value of the 6 min walk test and self-perceived symptom severity in older patients with chronic heart failure.

Background: The 6 min walk test (6-MWT) is a simple and popular test for evaluating functional status in patients with chronic heart failure (CHF). However, the prognostic value of the 6-MWT in a large, representative sample of CHF patients, and in patients with different degrees of left ventricular systolic dysfunction (LVSD) remains unclear.

Methods And Results: Of an initial population of 1592 patients, 212 died representing a crude death rate of 13.

Incorrect calculation of power outputs masks the ergogenic capacity of creatine supplementation.

This study assessed the effect of incorrect calculation of power output measurement on the ergogenic properties of creatine. Fifteen males performed repeated Wingate anaerobic tests, under baseline, placebo, and creatine conditions. Statistics showed significant differences (p < 0.
