Characteristics Controlled experimental comparison Peer reviewed
Sample size 20
Population 10 highly trained and experienced meditators and 10 subjects with no training or experience with meditation
Intervention Meditation
Duration Four successive days, with 5 minutes relaxation, 20 minutes meditation or rest, and 5 minutes relaxation each day
Measures Heart rate, skin resistance, respiration rate, systolic blood pressure, diastolic blood pressure, subjective cognitive arousal, subjective somatic arousal, subjective relaxation
Topics Meditation
Key findings Meditators tended to have higher heart rates and diastolic blood pressure than nonmeditators before meditating or resting. Meditation was associated with generally reduced arousal, but while meditating, meditators did not show lower arousal than nonmeditators did while resting. The authors state that these controlled results place qualifications on previously reported findings.

Abstract

On four successive days, 10 highly trained and experienced meditators were asked to relax for 5 minutes, meditate for 20 minutes, and then relax for 5 minutes. In contrast, 10 other subjects who had no training or experience with meditation were asked to relax for 5 minutes, rest for 20 minutes, and then relax for 5 minutes. Physiological arousal (heart rate, skin resistance, respiration rate, systolic blood pressure, diastolic blood pressure) and subjective arousal (cognitive, somatic, relaxation) were measured throughout the experiment. Results indicated that (a) prior to meditating or resting, meditators tended to have higher heart rates and diastolic blood pressure than did nonmeditators, (b) meditation was associated with generally reduced arousal, but (c) while meditating, meditators did not evidence lower levels of arousal than nonmeditators did while resting. This investigation employed controls, which were not used in previous investigations, and the results place qualifications on previously reported results. The results have implications for the study of personality functioning, stress management, and psychotherapy.
