so in terms of Brad tolling now we're going to lack of acidosis and fatigue is the physiological braking point of which the athlete cannot continue to exercise intensity in other words something when fatigue sets in the athlete they can't maintain the pace that they were continuing that you know it's going to slow them down or ultimately halt performance if we can delay fatigue or delay the onset of fatigue it's very important in sports which require anaerobic performance and these would be sports that you know they're no longer than a dozen minutes that they're intense outbursts
of energy outbursts of effort that the body is is going from a state of being supplied with sufficient air that muscles now are not getting sufficient air that they're working without air that are going into this anaerobic stage and you know very relevant to different sports such as for example boxing and sprinting you know 100 200 400 meters these athletes are driving themselves from a state of aerobic intensity into an aerobic intensity so when we look at reduced acidosis the metabolism of produces carbon dioxide and carbon dioxide forms carbonic acids and in turn dissociates into
hydrogen ion and bicarbonate when there's sufficient oxygen to the muscles the hydrogen iron is oxidized in the mitochondria to generate water renders insufficient oxygen all of the hydrogen ion cannot be oxidized and it associates with pyruvic acid to form lactic acid and while a small amount of lactic acid is beneficial too much is burning and cramping and ultimately is involved with fatigue so Brett toiling after an exhalation it causes a decrease to the concentration of oxygen to trigger increased lactic acid and at the same time Brett rolling after an exhalation is increased with carbon dioxide
and when carbon dioxide dissociates into hydrogen and bicarbonate we've got increased concentrations of hydrogen 9 to further acidify the blood so in terms of Brett rolling were deliberately the body into an anaerobic stage and it's conditioning the body to be able to tolerate this stage that fatigued and is delayed that the onset of fatigue is delayed so the athlete can maintain their performance so in terms of acidosis the increased carbon dioxide point myrrh holding the breath carbon dioxide is dissociating into hydrogen and bicarbonate and repeated exposure to increase acidosis it forces the body to make
adaptations in other words it's probably because of the buffering capacity that's improving and our buffering capacity is increased bicarbonate which is helping to neutralize hydrogen ions and by neutralizing hydrogen ion it's delaying the onset of fatigue the main buffering in the blood is haemoglobin and bicarbonate we've already showed that when we do a Brack tolling hemoglobin is increasing of course when we do breath-holding and the dissociation of carbon dioxide into hydrogen and bicarbonate our buffering capacity is increasing and within the skeletal muscle the proteins and phosphates and to a lesser extent bicarbonate they are the
buffers so even within skeletal muscle by holding the breath to increase bicarbonate we're improving our buffering capacity to neutralize hydrogen ions in our skeletal muscle level now what that means is that less hydrogen ion is going to be released into the blood so overall acidosis is reducing so it's possibly enhanced buffering capacity in the muscle compartments that's lowering the diffusion of hydrogen ions into the blood so how do we delay the onset of fatigue well according to one theory which is the central governor Terry the brain protects the body against the risks from extreme exertion
and at some point the brain tells the working muscles to stop or to slow down and in consideration of this theory fatigue it's not just a physical but also a psychological phenomenon and the purpose is to help maintain homeostasis when we subject the body to increase the acidosis is impairs homeostasis and Brett rolling is conditioning the brain to tolerate strong acid so it basically by conditioning the body to it it's teaching the brain that the body can go harder and faster without overdoing it and this is according to the central governor theory that we can
purposely drive the body into an anaerobic stage to teach the brain that basically that this is okay
