Mindfulness-Based Movement: A Polyvagal Perspective.

Integrative cancer therapies. 2018;(1):5-15
Abstract
Compelling evidence suggests that physical activity is an effective intervention for cancer survivors, including for those undergoing active cancer treatments. However, to date most evidence has emerged from interventions that have promoted moderate to vigorous physical activity. In this conceptual review, we argue that attention should be given to the entire continuum of physical activity from reducing sedentary behavior to increasing higher levels of physical activity when possible. In addition, considerable evidence in the cancer literature supports the value of mindfulness-based interventions as a means of helping patients and survivors cope with the variety of threats that accompany this disease. Based on the success of these two areas of research, we argue for conceptualizing and promoting physical activity as Mindfulness-Based Movement, using Polyvagal Theory as a theoretical framework to understand the role and value of Mindfulness-Based Movement as a potential intervention for cancer care and control.

Abstract
Due to differences in study populations and protocols, the hemodynamic determinants of post-aerobic exercise hypotension (PAEH) are controversial. This review analyzed the factors that might influence PAEH hemodynamic determinants, through a search on PubMed using the following key words: "postexercise" or "post-exercise" combined with "hypotension", "blood pressure", "cardiac output", and "peripheral vascular resistance", and "aerobic exercise" combined only with "blood pressure". Forty-seven studies were selected, and the following characteristics were analyzed: age, gender, training status, body mass index status, blood pressure status, exercise intensity, duration and mode (continuous or interval), time of day, and recovery position. Data analysis showed that 1) most postexercise hypotension cases are due to a reduction in systemic vascular resistance; 2) age, body mass index, and blood pressure status influence postexercise hemodynamics, favoring cardiac output decrease in elderly, overweight, and hypertensive subjects; 3) gender and training status do not have an isolated influence; 4) exercise duration, intensity, and mode also do not affect postexercise hemodynamics; 5) time of day might have an influence, but more data are needed; and 6) recovery in the supine position facilitates systemic vascular resistance decrease. In conclusion, many factors may influence postexercise hypotension hemodynamics, and future studies should directly address these specific influences because different combinations may explain the observed variability in postexercise hemodynamic studies.

Journal of bodywork and movement therapies. 2012;(1):109-14
Abstract
OBJECTIVE The purpose of this systematic review was to determine how Pilates exercises have impacted body composition (BC) on selected populations. METHODS A comprehensive literature search was performed using the keywords 'Pilates, body composition, systematic review, literature review, overweight, obesity, healthy weight, underweight' and their combination. RESULTS Seven studies met the inclusion criteria and after further quality analyses it was determined that there is currently poor empirical quantitative evidence indicating a positive effect of Pilates exercises on BC. Several methodological flaws were observed in the studies analyzed, including few full-text published studies looking into the effects of Pilates exercises on BC, a lack of true experimental research designs, limited standardization in measurement techniques, insufficient or no control of the nutritional status, and inconsistent instructor qualifications. CONCLUSION Well-designed research is needed to determine how Pilates exercises impact BC on selected populations.
