Research & references

Research listed on this page represents 40+ years of development of flow state science based on many research papers & time proven concepts that was effectively put together by the team of experts from different fields of expertise.

The system includes a number of new and upgraded concepts, specific language adaptation and systematic simplification in order to achieve maximum adoption/acceptance of the flow philosophy.

It provides us with a clarifying overview of how to achieve the flow state and how flow evolves into a trait.

CardioVascular disease & Hypertension
“The results of this follow-up study indicate that breathing retraining had lasting effects on both respiratory parameters measured. Subjects evidenced significantly higher end-tidal carbon dioxide levels and lower respiratory rates when compared to pretreatment levels measured three years earlier. Subjects also continued to report a decrease in the frequency of functional cardiac symptoms when compared to pretreatment levels. We conclude that breathing retraining has lasting effects on respiratory physiology and is highly correlated with a reduction in reported functional cardiac symptoms.”

Cancer
“The lung cancer patient should learn diaphragmatic breathing through pursed lips. Diaphragmatic breathing strengthens the diaphragm and the abdominal muscles. This will allow more air to move in and out of the lungs with less tiring of the chest muscles. When the diaphragm becomes weak, the patient compensates by using the shoulders and other muscles to help them breathe.”

“Results from several studies have described a relationship between pulmonary function and both all-cause and cause-specific mortality. The purpose of this study was to investigate the predictive value of pulmonary function by gender after 29 years of follow-up. These results suggest that pulmonary function is a long-term predictor for overall survival rates in both genders and could be used as a tool in general health assessment.”

Headache/Migraine
“Intervention showed significant clinical improvement in both groups. Headache frequency and intensity were reduced more in Yoga with conventional care than the conventional care group alone. Furthermore, Yoga therapy enhanced the vagal tone and decreased the sympathetic drive, hence improving the cardiac autonomic balance.

ADHD (Attention deficit hyperactivity disorder)
“A growing number of empirical studies have revealed that diaphragmatic breathing may trigger body relaxation responses and benefit both physical and mental health. In the present study, we investigated the diaphragmatic breathing as a single intervention method for sustained attention improvement.

DIAPHRAGMATIC BREATHING
“Diaphragmatic or abdominal breathing (the proper way to respire). Taking deep, diaphragmatic breaths is necessary to get the oxygen rich air deep into the base of the lungs, where three times as many blood vessels are available for respiratory exchange compared to the upper lung region.”

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4183256/


CORE ACTIVATION – PLB BREATHING TECHNIQUE WITH EXTENDED EXHALATION
“When you exhale fully, you use main breathing muscle diaphragm and all auxiliary respiratory muscles and contract them as a full three dimensional core system (squeezing muscles of the abdominal region). The main role in this action has a thoracolumbar fascia which connects them together (diaphragm, m. transversus abdominis, m. Multifidus, pelvic floor muscles,…).”
http://jrnlappliedresearch.com/articles/Vol5Iss3/Petrofsky.pdf


BREATHING & EMOTION
“One of the reasons why breathing can change how we feel is that emotions and breathing are closely connected. A revealing research study by Pierre Phillipot showed that different emotional states are associated with distinct respiration patterns.
http://www.tandfonline.com/doi/abs/10.1080/02699930143000392


CALMING EFFECTS OF SLOW & RHYTHMIC BREATHING
“For example, once you go below 10 breaths a minute you start to engage the parasympathetic nervous system, which helps the body relax when it has been injured. Slow breathing activates the vagus nerve, the primary cranial nerve, which is associated with a recuperative state.”
http://www.mindfulnessmd.com/2015/06/27/neuroscience-of-mindfulness-take-a-deep-breath/


IMPROVED OXYGENATION /PLB BREATHING TECHNIQUE
“(PLB – pursed lip breathing technique) creates an additional workload on the body by narrowing exhalation pathway, enabling slow and controlled exhale and forcing your body to adapt to breathing speed, which results in multitude of positive physiological adaptations, including higher lung capacity and more efficient tissue oxygenation.”
https://en.wikipedia.org/wiki/Pursed_lip_breathing
http://www.sciencedirect.com/science/article/pii/S001236921661485X


“… respiratory therapists teach this technique to their patients to ease shortness of breath and to promote deep breathing, also referred to as abdominal or diaphragmatic breathing.”

CONSCIOUS BREATHING

“…breathing techniques activate the parasympathetic (inhibitory) nervous system, thus slowing certain physiological processes down that may be functioning too fast or conflicting with the homeostasis of the cells (Jerath et al., 2006).”

SUFFICIENT BODY OXYGENATION (problem of chronic oxygen starvation/overbreathing/hyperventilation)
“Dozens more medical studies prove the same fact: not only people with chronic disease, but nearly all so called “normal subjects” breathe about 12 L/min (double the medical norm)”
http://www.normalbreathing.com/causes-of-hyperventilation.php


STRESS RESPONSE/RELEASE
“yoga-based practices (4) correct underactivity of the PNS and GABA systems in part through stimulation of the vagus nerves, the main peripheral pathway of the PNS, and (5) reduce allostatic load.”
http://www.ncbi.nlm.nih.gov/pubmed/22365651

“Diaphragmatic Breathing Reduces Exercise-Induced Oxidative Stress … The consequence is a lower level of oxidative stress, which suggests that an appropriate diaphragmatic breathing could protect athletes from long-term adverse effects of free radicals.”
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3139518/

“Stress responses can occur as a reaction to physiological (or systemic) challenge or threat; signals from multiple parts of the brain send input to the paraventricular nucleus (PVN) within the hypothalamus.”
