The two brain method represents a revolution in exercise science. In particular, latest research findings have totally changed our understanding of the term "fatigue", which until recently was thought to be peripheral fatigue, occurring in the muscles and heart. New studies have shown that fatigue is "central" and that it actually represents fatigue of the autonomic nervous system. The Lonhea method applies this science by quantifying workload during exercise; the data obtained then allows us to set an exercise progression which minimises the risk of injury. This is particularly important for athletes who may have a tendency to overtrain.
All of the brain's neurotransmitters are produced in the reptilian brain, which also determines the quantity of each type of neurotransmitter produced. The reptilian brain is also the main activator of all the cortical areas of the brain. Optimising the function of the reptilian brain is therefore one of the key aims of the two brain method.
Burn out is consequence of a significant dysfunction of the reptilian brain. Various stresses - environmental stress, bad nutrition, lack of physical activity, emotional overload, lack of sleep - leave the individual in a state of exhaustion. This manifests as a virtual disappearance of the parasympathetic function, and together with this the ability to restore the necessary resources to contend with each of these sources of stress and to ensure a good recuperation. Without these resources, all the functions of the autonomic nervous system are disrupted, immunity is no longer guaranteed, and digestive and cardiac function is weakened, which can lead to the development of serious illness.
My opening statement is not something you’d usually expect to hear - but we all need stress to live. It’s a key body functionality which releases an ‘adaptation’ mode for us to react to the situations life throws at us, and our ability to adapt is a clear measurement of our state of health. There are three elements to stress; Chemical, Physical and Emotional, and when one, or all three elements become a negative aspect, the results can be damaging.
When it comes to chemical and physical stress, the first reaction is an increase of oxidant stress in the most exposed parts of our body. If this oxidant stress is not well managed and the effect continues to grow, it will lead to the next step of the process – Inflammation. Once this process begins it will target the immune system. In our current society (fast paced lives mixed with city living), the intestine and the lung mucous membrane are at the greatest risk as they are the most exposed – we inhale fine particles in the air and xenobiotic (unnatural processed elements) in our food.
Emotional stress can result in something entirely different – it’s all in the development. When emotions (messages from the cerebral cortex) reach the reptilian brain (the co-ordinator of all essential functions), it actually has an initial positive impact on your health, resulting in an attitude called . The impact becomes negative, however, when these messages are released over a prolonged period of time at a heightened level. As this happens your control decreases and leads to the hyper activity of the autonomous nervous system. You might experience symptoms such as heart palpitations, hot flushes, irregular heart rhythm, asthma attack or an irritable colon. This could develop into exhaustion and a demise of the reptilian brain which could result in the failure of the digestive and immune functions, sleeping disorders and eventually serious illnesses and diseases.
