Effects of Mindfulness Practice on Performance and Factors Related to Performance in Long-Distance Running: A Systematic Review

Fatigue, boredom, pain, performance anxiety, and negative thoughts are challenges characteristic of competitive running. One psychological technique that is gaining support and has been successfully implemented in sport is the practice of mindfulness. Where conventional psychological skills training interventions aim to change dysfunctional thoughts and emotions, mindfulness focuses on altering the relationship to physiological and psychological states. This could help in dealing with the demands of distance running but this has yet to be examined. This article was focused on reviewing mindfulness interventions on performance and performance-based factors in long distance running, assessing (a) mindfulness scores, (b) physiological performance-related factors, (c) psychological performance-related factors, and (d) performance outcomes. A search of relevant electronic databases yielded seven studies which met the inclusion criteria. The review provided some tentative support for the use of mindfulness interventions regarding: reducing competitive anxiety, attenuating immune responses to high-intensity running, and increasing state mindfulness. However, due to the methodological weaknesses of studies more research is required using high-quality randomized controlled trial designs

The Effect of Mindfulness-Based Interventions on Stress, Depression and Anxiety During the Perinatal Period in Women Without Pre-existing Stress, Depressive or Anxiety Disorders: a Systematic Review and Meta-analysis of Controlled Trials

Objectives: The objective of this systematic review and meta-analysis was to examine controlled trial evidence for the effectiveness of mindfulness-based interventions on stress, anxiety and depression in the perinatal period in women without pre-existing mental health issues. Methods: Six databases were searched for studies exploring the effects of mindfulness-based interventions on mental health outcomes of women during the perinatal period. Quality of both controlled trial meeting inclusion criteria were assessed using a tool specifically designed for meta-analyses of mindfulness-based interventions. Effect sizes were extracted for measures of mindfulness, depression, stress and anxiety outcomes. Effects were pooled in separate meta-analyses for all outcomes except anxiety which lacked sufficient studies. Results: Twelve studies were analysed. Pooled effects suggest that mindfulness-based interventions cause small but clear increases in mindfulness and reductions in depression in women without pre-existing disorders. Effects of mindfulness-based interventions on other outcomes were unclear and confounded by heterogeneity. Conclusions: Available controlled trial evidence suggests that mindfulness-based interventions improve mindfulness and decrease symptoms of depression during pregnancy in women without pre-existing mental health issues and might be a useful approach to prevent or attenuate the development of depression in the perinatal period
