Hit, move, run, Dodge … are <\/strong>all activities that require a lot of energy, but how it is produced by our body??? What are the energy systems (IF)<\/strong>???<\/p>\n

For if you mean the mechanism by which ATP (adenosine Tri<\/strong> phosphate) is produced, our energy money, through a process (hydrolysis) that requires water and an enzyme (ATPase).
\nThis cleavage produces, in addition to energy, one molecule of adenosine diphosphate<\/strong> (ADP), a free molecule of phosphate (P) and H + a hyd<\/strong>rogen ion (H + Beno will serve you later<\/em>).
\nThere are three energy systems (anaerobic, lactate anaerobic and aerobic lact<\/strong>acid), and have different features (amoun<\/strong>t of energy produced per unit of time measured in Kcal\/min) and capacity (t<\/strong>he total amount of energy that the system can produce).<\/p>\n

ANAEROBIC METABOLISM LACTACID<\/strong>:<\/p>\n

The reserves are used, stored directly into the muscle. \u00a0of ATP and Creatine phosphat<\/strong>e (CP).
\nFor re-synthesise ATP from ADP is used the energy produced by the splitting of the CP.
\nIn this case it is not necessary the presence of oxygen (anaerobic) and does not produce lactic acid (lactacid).
\nThis system has a very high potency but very little ability, so it is used for tasks that are short and very intense (es. 100 meters, Weightlifting etc.)<\/p>\n

ANAEROBIC LACTATE METABOLISM<\/strong>:<\/p>\n

The fuel o<\/strong>f this energy system are carbohydrate<\/strong>s in the form of blood glucose and glucose derived from glycogen lisi (from hepatic glycogen and muscle).<\/p>\n

Without going into details of the biochemical processes that lead to the production of ATP, what we want to know is that within the muscle pyruvate is formed which, <\/strong>in the absence of oxygen, is transformed into lactic acid (or lactate)<\/strong>. Mistakenly think it’s responsible to the burning sensation that is felt when stress is prolonged, it is actually the accumulation of hydrogen ions H + (do you remember?<\/em>) that leads to lower the ph (making the environment more acidic) thereby inhibiting the release of calcium ions and actually not allowing more muscle contraction.
\nAnother error related to lactic acid is to hold him responsible of muscular pains (DOM<\/a>S) present in the days after the workout.<\/p>\n

The capacity and power of this energy system are intermediate, for<\/strong> this reason it is important in the short to medium term medium-high intensity, typical of some combat sports<\/strong>.<\/p>\n

AEROBIC METABOLIS<\/strong>M:<\/p>\n

Aerobic metabolism has high capacity but low power, <\/strong>then produces energy much more slowly.
\nThe fuel of this energy system is the carbohydrates (in this<\/strong> case the muscle and liver glycogen) and fatty acids (for hy<\/strong>drolysis of triglycerides) and requires oxygen<\/strong>.
\nThe latter is introduced through breathing and piped into the blood where hemoglobin, ends carried in the muscles for ATP synthesis. Those suffering from anemia (low hemoglobin pathological) will see this reduced oxygen-carrying capacity, compromising the performance.
\nWith this energy system you can transform pyruvate (before it becomes lactic acid), acetyl-CoA one <\/strong>molecule essential for the Krebs cycle res<\/strong>ponsible for the formation of ATP.
\nSaid this reasoning a little is easy to understand that a major disposal efficient aerobic metabolism pyruvate and then allow to postpone the excessive accumulation of lactic acid, allowing to maintain the sporting performance<\/strong>.<\/p>\n

A good Boxer, with an aerobic system well coached, in minute break between rounds, you will be able to retrieve and restore the most of their energies, that is why it is essential to enter into<\/strong> the programming aer<\/strong>obic workouts (power and capacity) in the working sessions.<\/p>\n
