Acute Psychological Responses to Qigong Exercise of Varying Durations

Qigong exercise has been shown to induce acute psychological changes of a positive nature; but whether longer durations have greater effects than shorter ones is not known. Forty-one regular qigong practitioners therefore engaged in either 30 or 60 min of qigong exercise within a randomized cross-over design. Measures of mood, anxiety, activation, and hedonic tone were obtained pre- and post-exercise. Results showed benefits of the same magnitude in the two conditions: more positive mood states, reduced state anxiety, and enhanced perceived pleasure. Thirty minutes of qigong exercise thereby seems to be sufficient to provide psychological benefits, and with no additional benefits detected after 60 min. This finding is important for those having little time or motivation to engage in activities of longer durations. In addition, health professionals prescribing exercise for health benefits can prescribe shorter exercise sessions with confidence knowing that positive psychological effects can also occur after a shorter exercise bout.
