Article Synopsis
  • The study focused on a community-based exercise program (CBE) for patients with moderate COPD, assessing its feasibility and effectiveness compared to regular exercise without supervision.
  • CBE participants showed significantly improved treadmill endurance and increased muscle strength compared to the control group after 12 weeks of training under a certified personal trainer.
  • Overall, the findings support CBE as a viable option for enhancing physical activity in moderate COPD patients, although health status, as measured by SGRQ, did not show significant improvement.

Introduction: Firefighters perform strenuous muscular work while wearing heavy, encapsulating personal protective equipment in high temperature environments, under chaotic and emotionally stressful conditions. These factors can precipitate sudden cardiac events in firefighters with underlying cardiovascular disease. The purpose of this pilot study was to deploy and explore the feasibility of the resting "advanced" 12-lead electrocardiogram (A-ECG) as a remote firefighter risk assessment tool for improved assessment of cardiac risk.

Sudden cardiac deaths experienced by firefighters in the line of duty account for the largest proportion of deaths annually. Several fire service standards for fitness and wellness have been recommended but currently only 30% of U.S.

Objectives: Physical exercise has been shown to benefit diverse medical and behavioral conditions. This study assesses the feasibility and efficacy of an 8-week endurance and resistance training program on fitness measures in individuals undergoing residential treatment for methamphetamine (MA) dependence.

Methods: A total of 39 MA-dependent individuals were randomized to 3 days/week of exercise training (ET, n = 15) or health education without training (equal attention [EA], n = 14) over 8 weeks.

Purpose: To assess cardiothoracic structure and function in patients with pectus excavatum compared with control subjects using cardiovascular magnetic resonance imaging (CMR).

Method: Thirty patients with pectus excavatum deformity (23 men, 7 women, age range: 14-67 years) underwent CMR using 1.5-Tesla scanner (Siemens) and were compared to 25 healthy controls (18 men, 7 women, age range 18-50 years).

Background: Because treadmill exercise testing is more representative of daily activity than cycle testing, we developed treadmill protocols to be used in various clinical settings as part of a two-year, multicenter, chronic obstructive pulmonary disease (COPD) trial evaluating the effect of tiotropium on exercise.

Methods: We enrolled 519 COPD patients aged 64.6 ± 8.

Objective: The objective of this study was to examine the effect of Cs-4 (Cordyceps sinensis) on exercise performance in healthy elderly subjects.

Design: Twenty (20) healthy elderly (age 50-75 years) subjects were enrolled in this double-blind, placebo-controlled, prospective trial. The subjects were taking either Cs-4 333 mg or placebo capsules 3 times a day for 12 weeks.

Article Synopsis
  • In COPD patients, tachypnea (rapid breathing) can lead to dynamic hyperinflation by reducing the time available for exhalation, affecting lung capacity.
  • A study involving 14 stable COPD patients measured inspiratory capacity (IC) while they paced their breathing at different rates (20, 30, and 40 breaths per minute) using a metronome.
  • Results showed significant reductions in IC after just 30 seconds of tachypnea, indicating that dynamic hyperinflation develops quickly and consistently, suggesting this method could help assess the condition in COPD patients effectively.
