“…Effects of Qigong practice on electrocardiographic parameters (Lee et al, 2000 , 2003 ), blood pressure (Lee et al, 2003 ; Cheung et al, 2005 ), and breathing frequency (Sun, 1988 ) were investigated. Positive effects of Qigong practice on mental health were shown in anxiety disorders (Lee et al, 2004 ; Abbott and Lavretsky, 2013 ; Chan et al, 2013 ), posttraumatic stress disorders (Grodin et al, 2008 ; Kim et al, 2013 ), major depression (Tsang et al, 2003 ; Wang C. W. et al, 2013 ; Wang F. et al, 2013 ; Yeung et al, 2013 ; Yin and Dishman, 2014 ; Liu et al, 2015 ; Martínez et al, 2015 ), in the burnout syndrome (Stenlund et al, 2009 , 2012 ), and in tinnitus (Biesinger et al, 2010 ). In recent studies, a stress alleviating effect was shown in healthy practitioners (Posadzki et al, 2010 ; Terjestam et al, 2010 ; Glei et al, 2012 ; Sousa et al, 2012 ; Hwang et al, 2013 ; Shim, 2014 ; Wang et al, 2014 ).…”
