ABSTRACT
BACKGROUND:
Limited exercise capacity is common in the elderly. Kinetics of recovery oxygen consumption plays an important role in determining exercise capacity. This study was performed to evaluate the kinetics of recovery oxygen consumption as well as peak oxygen consumption during exercise and recovery in the elderly.METHODS:
Thirty healthy volunteers were included for this study. They were divided into three groups according to their ages(20 to 39; 40 to 59; and over 60). All subjects performed symptomlimited maximal treadmill exercise.RESULTS:
Peak oxygen consumption(pVO2, ml/min/kg) was gradually decreased with the age. Half-recovery time of peak oxygen consumption(T1/2VO2) was maintained from third to sixth decades without significant changes, and then rapidly delayed in the elderly.CONCLUSION:
Kinetics of recovery oxygen consumption was rapidly and markedly delayed in the elderly and this may result in the exercise intolerance.
