What is the difference between aerobic and anaerobic replenishment of energy

In reality, the energy systems never work in isolation and are ALL working at different percentages at different times. As stated the percentage use of each of the energy systems will be constantly changing particularly in games type sports where the intensity and duration of the exercise being performed is constantly changing.

For example during a game of football a wide player may sprint down the line beating defenders using approximately. Then when he stops to prepare to cross the ball when confronted by a defender the proportion of each system will change because the intensity of the exercise will drop and hence the proportion of the energy systems being used will change:.

At the end of a match, competition or activity the proportion of each energy system will be totalled. Examples of this can be seen in the table below. A common misconception with energy systems and the energy continuum is that during exercise the body will replenish ATP using one system e. In practise, as the intensity increases there will be a gradual move towards the anaerobic glycolysis and ATP-PC systems from the aerobic system, but the aerobic system will still be helping to replenish ATP.

As with the energy systems the candidates must link the energy continuum to the intensity and duration of the exercise and fitness level of the performer if appropriate within the answer see Energy Systems top tips. Watch the player who has a red and white circle around them. Throughout the clip, all energy systems are being used interchangeably. The intensity of the play dictates the predominant energy system supplying ATP. An example of this is when the player carries the ball into contact and works at a high intensity, the ATP-PC system is the predominant energy system.

As exercise intensity increases then so does heart rate and lactic acid. When the player is working anaerobically the heart rate is above the anaerobic threshold at beats per minute, furthermore when they produce more than 5 minimoles of lactic acid they are also deemed in the anaerobic zone.

The opposite is the case towards the end of the clip, where the player is less involved and the aerobic energy system becomes the predominant energy system. There is also a drop in heart rate and levels of blood lactate are also reduced.

If you follow the player that is highlighted, there are a number of mechanisms that are controlling his heart rate and breathing rate. The three main control mechanisms for heart rate and stroke volume are hormonal, neural and intrinsic control. Hormonal control is the influence of adrenaline and noradrenaline on heart rate. Within the clip, just before the player is about to receive the ball there will be a slight anticipatory rise in heart rate cause by the release of adrenaline; this prepares the player for the subsequent period of play.

Acetylcholine is another hormone, but this has the opposite affect and is responsible for reducing heart rate. Neural control is a main control mechanism for both heart rate and respiration or breathing. It is made up of receptors picking up a variety of changes in the body. As exercise intensity increases, chemoreceptors pick up chemical changes in the blood due to increased levels of carbonic and lactic acid.

Proprioceptors detect the increase in movement within the joints and muscles, baroreceptors detect pressure changes within the arteries and finally thermoreceptors detect increases in body temperature. These are the systems of the body that produce the energy for us to move fast, powerful, or maybe just for a long time. Each system has its own strength and weakness but they all work together to keep you as efficient as possible.

Now that you know how you replenish ATP through different systems you have an understanding on how your body reacts to different activity levels. Just eat the right things and keep training each system properly and they will keep you moving.

My recent labs show my atp is low. I am wondering why? Thoughts on low atp in athletic 41 year old female. Hi Courtney- Low ATP is quite rare but could be caused by a handful of things but low phosphorus is often the cause and diet is usually responsible.

Being vegetarian can make it harder. There are some hormonal and hereditary causes which would take more lab work to diagnose. Previous Next. Related Posts. Post-Exercise Recovery by Elizabeth Criner. Courtney January 9, at am. It is believed that Ice Baths reduce the swelling around the muscle micro-tears and reduce the pain that they cause, this means that the performer is able to train at a higher level the next day.

It must be noted that research on this is not conclusive. Massage can serve two purposes; the first is psychological benefits e. Secondly it can help physically by returning de-oxygenated blood from the muscle tissue to the heart to be re-oxygenated. Recent studies have concluded that compression clothing can help recovery by maximising the pumping action of the muscles in returning blood to the heart and help with subsequent removal of lactic acid and blood lactate.

The candidate must also be able to provide specific examples of how the methods to speed up recovery and why each are used. Also the cool down can speed up the re-saturation of myoglobin. Example 2 A high carbohydrate meal including protein can help restore muscle glycogen and blood glucose levels. The optimum time for uptake of glycogen into muscles is within 30mins of ceasing exercise.

Protein can help repair damaged muscle tissue and help re-growth. Explain the terms alactic and lactacid oxygen debt and describe the strategies you have used to speed up these recovery processes.

High anaerobic capacity is essential to any team gamer player. Outline the physiological processes that will happen during a 5-minute recovery period after intense anaerobic exercise 5. Cool down is an essential aspect of the recovery process. Provide an example of an appropriate cool down for your sporting activity and explain the physiological benefits to the performer.

Fatigue is inevitably linked to the energy systems and the by products of producing energy. Here are the main reasons why we fatigue occurs if exercise intensity and duration are significant enough.
