Article Abstract:
Use of respiratory-inductive plethysmography in an analysis of the changes in thorax or abdomen contribution helps study the variation with age in ventilation components of males during exercise. These contributions are reduced in younger males, while in the elder males there is an enhancement of the respiratory frequency during exercise. Thorax stiffening in the aged leads to a ventilation pattern where there is more diaphragmatic motion and shallow rapid breathing. Chest strapping helps reduce thoracic compliance and simulate in the young the breathing process of the elderly.

Article Abstract:
Exercise rehabilitation can improve disabilities of patients with coronary artery disease (CAD). Gains in aerobic fitness and muscle strength are common even in the most disabled patients and women patients. Physician-referred patients are most likely to participate in a program, which is typically covered by medical insurance. Since exercise conditioning itself may not extend life, the emphasis remains on improved physical functioning and other advantages. Heart patients may also have special needs, such as access to transportation and psychosocial factors.

Article Abstract:
An exercise program for aged patients with coronary problems enhances the peak and submaximal exercise efficiency, indicating the presence of a threshold effect. This threshold effect is stimulated by exercise, causing submaximal training affects. The patients undertaking exercise programs possess minute ventilation at standard workload and lower heart rate.
