Background: Loss of bone mass is common after spinal cord injury (SCI). One rehabilitation modality that has shown some promise for maintaining bone health is the functional electrical stimulation (FES) cycle ergometer. Although there has been some research investigating bone health and FES cycle ergometry, few have provided a detailed description of the changes that can occur in bone mass and ...

INTRODUCTION Common modalities of clinical exercise testing for outcome measurement after pulmonary rehabilitation (PR) include walk tests, progressive cycle ergometry, and cycle endurance testing. We hypothesized that patients' responses to PR, as measured by those 3 tests, are differentially correlated, and we designed a study to investigate the tests' capacity to detect changes after PR. M...

BACKGROUND Although exercise induced desaturation can occur in patients with chronic obstructive pulmonary disease (COPD), little is known about its frequency during everyday exercise, or how it relates to dyspnoea or prior drug treatment. METHODS The effects of 200 micrograms inhaled oxitropium bromide, an anticholinergic bronchodilator drug, on spirometric values, dyspnoea score, and oxygen...

Maintenance of reduced or elevated body weight results in respective decreases or increases in energy expended in physical activity, defined as 24-h energy expenditure excluding resting energy expenditure and the thermic effect of feeding, beyond those attributable to weight change. We examined skeletal muscle work efficiency by graded cycle ergometry and, in some subjects, rates of gastrocnemi...

The purpose of this review is to examine the literature that has investigated mechanomyographic (MMG) amplitude and frequency responses during dynamic muscle actions. To date, the majority of MMG research has focused on isometric muscle actions. Recent studies, however, have examined the MMG time and/or frequency domain responses during various types of dynamic activities, including dynamic con...

Objectives: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...
