“…This is a gently progressive regimen of strengthening and endurance training occupying about 11–12 minutes a day and aiming for an age related “target.” This programme requires no special equipment and is considered to be safe, having been used in studies of patients with cardiac23 and pulmonary disorders 24…”

Objective-To determine whether a programme of simple, moderate exercise training increases blood volume and improves orthostatic tolerance in patients with attacks of syncope or near syncope related to orthostatic stress.Design-An open study in 14 patients referred with unexplained attacks of syncope, who were shown to have a low tolerance to an orthostatic stress test. Measurements were made of plasma and blood volumes, orthostatic tolerance to a test of combined head up tilt and lower body suction, and baroreceptor sensitivity by applying subatmospheric pressures to a chamber over the neck. Cardiorespiratory fitness was assessed from the relation between heart rate and oxygen uptake during a graded treadmill exercise test. Assessments were made before and after undertaking an exercise training programme (Canadian Air Force 5BX/XBX). Results-After the training period, 12 of the 14 patients showed evidence of improved cardiorespiratory fitness. All 12 patients were symptomatically improved; they showed increases in plasma and blood volumes and in orthostatic tolerance, and decreases in baroreceptor sensitivity. Despite the improved orthostatic tolerance, values of blood pressure both while supine and initially following tilting were lower than before training.

“…The number of each exercise increases at a rate and to a target which are age and sex related. The regime is considered safe and has been used in the rehabilitation of patients with both cardiac (Raffo et al 1980) and pulmonary (Mungall & Hainsworth, 1980) disorders.…”

The effect of physical training on an individual's ability to withstand an orthostatic stress is unclear. This study was undertaken to determine the effects on orthostatic tolerance in healthy volunteers of training at a level appropriate for unfit subjects and cardiorespiratory patients. In 11 asymptomatic, untrained subjects the following assessments were made: plasma volume by Evans Blue dye dilution and blood volume derived from haematocrit; carotid baroreceptor sensitivity from the slope of the regression of change in cardiac interval against pressure applied to a neck chamber; orthostatic tolerance as time to presyncope in a test of head-up tilting combined with lower body suction; exercise test relating heart rate to oxygen consumption. Subjects were then given a training schedule (.5BX/XBX, Royal Canadian Air Force) involving 11-12 min of mixed exercises per day until an age/sex related 'target' was reached. Following training all subjects showed evidence of improved fitness, seen as decreases in heart rate at an oxygen uptake (V0J of 1.5 1 min-' and in the elevation of the regression line between hearr rate and Vo,. All also had increases in plasma and blood volumes and decreases in baroreceptor sensitivity. Seven of the subjects showed increases in orthostatic tolerance. Improvement in orthostatic tolerance was related to a low initial tolerance, and was associated with increases in plasma volume and decreases in baroreceptor sensitivity. These results show that moderate exercise training increases orthostatic tolerance in subjects who do not already have a high initial tolerance and suggest that training may be of value in the management of untrained patients with attacks of syncope due to orthostatic intolerance.

“…The advantages of circuit training include the ability to supervise large numbers of patients in a small area, the number of muscles trained for leisure and work activities and the variety, which removes the boredom of single exercise programmes 19 . The supervised circuit can be modified to devise a home circuit for the patient to perform, so that visits to the centre can be made less frequent and the confidence created to exercise unsupervised 20,21 …”

“…Patients with angina can benefit greatly from exercise treatment since the peripheral training effect results in a lower heart rate and lower systolic BP during effort, thus raising the angina threshold. Nearly all studies of the effects of physical training in angina report an increase in exercise capacity and a decrease in symptoms after training 21,55 . Most find that a proportion, from 30 – 100%, lose the symptom altogether for normal daily activities.…”

SUMMARYIn 1957, Hellerstein and Ford1 defined rehabilitation as ‘the process by which a patient is returned realistically to his greatest physical, mental, social, vocational and economic usefulness and, if employable, is provided an opportunity for gainful employment in a competitive industrial world’. They stressed the importance of starting the rehabilitation process ‘at the moment the patient is first stricken with his disease’, of mobilising the patient as soon as is practical and of paying close attention to the emotional as well as physical consequences of the attack. They believed that 80% of the aftercare of cardiac patients could be managed by the ‘private physician’ and only a minority required the attention of a specialist team.The time scale used in 1957 (three to four weeks in hospital) was rather different to the one we use today, but otherwise most of what he suggested then has scarcely been improved upon since. In 1968 Hellerstein2 went on to describe the physical training programme he had devised to improve the fitness of ‘habitually lazy, hypokinetic, sloppy, endomesomorphic over‐weight males’ who were the usual victims of myocardial infarction. He wished to ‘add life to years and perhaps add years to life’. The conclusions from his original study were that ‘an active intervention programme of conditioning including exercise, weight reduction, diet therapy, and cessation of smoking is feasible, reasonably acceptable and appears to be of benefit in the treatment of coronary heart disease’.
