Three energy pathways in use.
During most exercise routines anaerobic and aerobic training will most likely be conducted. On training days the majority of athletes will spend more than a few seconds training, therefore utilizing all three of the ATP production pathways. With production times on each pathway being limited they must work in cohesion to maintain a constant supply of ATP during workouts.
Anaerobic training, such as heavy weightlifting, does not usually require more than one or two seconds of a ballistic maximum effort type movement for one repetition. Thus the ATP/CP energy pathway is utilized until all ATP is depleted. According to “ISSA”, depletion usually occurs within 1.26 seconds and CP usually depletes within ten seconds of maximum effort. All activities begin with the ATP/CP pathway regardless of there intensity.
Knowing that all exercises start with the ATP/CP pathway and ATP/CP stores are depleted within seconds, the glycolytic pathway assists in production of ATP in the anaerobic pathways. The glycolytic pathway creates ATP by breaking down glycogen or glucose. This process creates lactic acid. The process could continue but the buildup of lactic acid (anaerobic threshold) causes muscle fatigue. In training the glycolytic pathway could be used to continue your final sets of heavyweight lifting but due to the anaerobic threshold, the glycolytic pathway is usually only good for about eighty seconds, then the aerobic pathway will take over.
Anaerobic pathways for ATP utilization and production falter after a short time. Therefore any activity lasting longer than two minutes will use the oxidative pathway. The oxidative pathway produces much more ATP than the two anaerobic pathways and

Essay about exercise and physiology strength

expand a maximal amount of energy in one or a series of strong, sudden high-intensity movements or apply a successive and equal force rapidly; in this case carrying out a maximum number of sit ups in 30 seconds. Explosive strength predominantly uses the ATP/PC system. This is because although it is anaerobic it represents movements of a higher intensity but of shorter duration than dynamic which predominantly uses the lactic acid system. The main muscle contraction is concentric and takes advantage of…

Hydration: Creatine Phosphate Energy Essay

the body. Through the use of adenosine triphosphate (ATP) the body is able to maintain a constant supply of energy. APT is formed during a reaction between adenosine diphosphate (ADP) and a molecule of phosphate. ATP consists of a molecule of adenine and three phosphate groups. When the ADP joins with the phosphate molecule energy is stored within the bonds, when the bonds are broken the energy is released. Energy can also be released when ATP is combined with water. The body can function both…

creatine in sports Essay

has been lost from the ATP it is now called ADP (adenine Di-phosphate). The reaction is as follows ATP (hydrolysis)=ADP + Energy. Now you have free ADP as a product from the ATP hydrolysis. ADP is pretty much useless in the body unless it is converted back into ATP. Now this is where creatine comes into play. The phosphate bound creatine donates it's phosphate group to the ADP to re-form ATP.” What this is saying is that when you use energy it takes a phosphate away from ATP that then changes to ADP…

Why Do O2 Requirements Change

cellular respiration is a metabolic process that converts nutrient energy into ATP through the breakdown of food that’s stored as sugar. These processes are vital for cells to perform essential life functions. During respiration (breathing), ATP synthesis is facilitated by aerobic respiration, which uses oxygen. Being the electron acceptor, oxygen is an important part of the electron transport chain, which synthesizes ATP from the nutrients. Electrons are transferred between proteins, which pump hydrogen…

Inital Responses Essay

Increase in vasodilation Anticipatory rise Breathing rate increases Increase in tidal volume More oxygen is used Increase of carbon dioxide Nervous control of muscular contraction Action Potential(electrical impulse) Muscle Spindles Phosphocreatine- ATP system Lactic acid energy system Cardiovascular system responses An initial response of the cardiovascular system is an increase in blood pressure. This happens because during exercise the muscles need more oxygen. So the heart then pumps more blood…
