OBJECTIVE The objective was to investigate effects of dieted weight reduction on walking ability in obese women. METHODS Fifty-seven obese women 44.1 +/- 10.7 years, body mass index 37.1 +/- 3.4 kg x m(-2) performed an indoor walking test. Speed, oxygen consumption and heart rate were measured, perceived exertion and pain graded and oxygen cost calculated. Maximum oxygen uptake (VO2max/kg) wa...

Parkinson's disease (PD) is one of most disabling disorders of the central nervous system. The motor symptoms of Parkinson's disease: shaking, rigidity, slowness of movement, postural instability and difficulty with walking and gait, are difficult to measure. When disease symptoms become more pronounced, the patient experiences difficulties with hand function and walking, and is prone to falls....

A retrospective analysis was made of the reproducibility of a treadmill exercise tolerance test performed on patients with angina pectoris to an end point of moderately severe (3+) angina. One hundred and forty tests (70 pairs) in 63 patients were found to meet criteria for inclusion in the study. In 30 patients a comparison of the first test the patient had ever had with a subsequent test reve...

BACKGROUND The development of portable liquid oxygen systems, capable of delivering high flow rate oxygen for long periods, justifies reassessment of the value of supplemental oxygen to aid exercise tolerance in patients with chronic respiratory insufficiency. The type of exercise test and the low oxygen flow rates previously used may account for the variable and often poor responses to supplem...
