Mindfulness skills, psychological flexibility, and psychological symptoms among physically less active and active adults

Mindfulness skills, psychological flexibility and psychological symptoms were compared among 58 physically less active and 50 physically active adults who were recruited and classified based on their self-reported physical activity. Additionally, this study evaluated the association of objectively measured physical activity with psychological variables. Methods: Participants completed questionnaires evaluating their mindfulness skills and psychological flexibility as well as their psychological and depressive symptoms. Physical activity was assessed objectively using an accelerometer for seven consecutive days. Results: Based on the self-reported physical activity levels physically active individuals had better mindfulness skills and less psychological and depressive symptoms compared to physically less active adults. A consistent correlation was observed between objectively measured physical activity and psychological well-being. Conclusions: This study support the view that physically active adults had better psychological wellbeing compared to physically less active adults. These results also suggest that a physically active lifestyle is related to better mindfulness skills and having less psychological and depressive symptoms. © 2014 The Authors.

Living a sedentary lifestyle has become a widespread health problem in Western countries, and is one of the causes of chronic diseases such as type 2 diabetes and cardiovascular disease (Lee, Shiroma, Lobelo, Puska, & Blair, 2012). Physical activity has also been inversely associated with mental disorders such as depression (Dunn, Trivedi, & O'Neal, 2001; Galper, Trivedi, Barlow, Dunn, & Kampert, 2006; Lucas et al., 2011), and this association seems to be bi-directional. It has been found that individuals who exercise at least two to three times a week experience significantly less anger, cynical distrust and stress compared to those who exercise less or not at all (Hassm en, Koivula,&Uutela, 2000). Furthermore, a higher sense of coherence and a stronger feeling of social integration has been reported in regard to individuals who exercise at least twice a week in comparison to their less active counterparts (Hassm en et al., 2000). On the other hand, lack of psychological well-being, such as in the form of depression, may also contribute to a sedentary lifestyle and poor adherence to physical activity behaviour (Roshanaei-Moghaddam, Katon, & Russo, 2009). Mindfulness is a concept that has attracted researcher and practitioner attention worldwide during the last decade (Baer, 2003; Brown & Ryan, 2003) and has become as an important issue in health promotion and disease prevention research (Greeson, 2009). Mindfulness involves attending to relevant aspects of experience in a non-judgemental manner. In mindfulness training, the goal is to maintain awareness moment by moment, disengaging oneself from beliefs, thoughts, and emotions (KabatZinn, 1982; Ludwig & Kabat-Zinn, 2008). A number of studies have evaluated the associations between mindfulness and different health behaviours. Mindfulness skills have been associated with better well-being (Baer, 2003; Hofmann, Sawyer, Witt, & Oh, 2010), healthier eating practices, and better quality of sleep and physical health (Murphy, Mermelstein, Edwards, & Gidycz, 2012). In addition, mindfulness skills have also been recognised as an important element involved in disengaging individuals from their automatic thoughts, habits, and unhealthy behaviour patterns (Baer, Fischer, & Huss, 2005). Furthermore, several studies have shown that greater levels of mindfulness are associated with higher levels of physical activity * This research was supported by Finnish Ministry of Education and Culture. * Corresponding author.
