As your body enters 'steady state' exercise it responds by recruiting the aerobic enery system. This system operates at a low intensity for long time durations and uses O2 as well as fats and CH02 to produce ATP. As the intensity is low, this energy system is able to keep up with the demands of 02 consumption.

∙ 7y agoAs we begin to take part in exercise multiple muscle groups begin contracting in order for the running action to take place, these are more contractions than you experience when not exercising, this can cause excess heat to be generated, this heat then travels from the muscle fibers to the skin, this also then generates sweating to take place this is a process called
vasodilation. capillaries near the surface of the skin will increase in size to increase blood flow and assist the removal of heat from the body, Because of this when taking part exercise the face may turn red

∙ 11y agoEnergy systems response to acute exercise happens when the exercise is a high intensity, which is too much for the cardiovascular and respiratory system to deal with. The first response is to use the creatine phosphate energy system. This works in the fast-twitch muscle fibre of the muscles high energy creatine phosphate compounds which are able to break down extremely quickly to create large amounts of ATP. ATP is where we get the energy from to continue and this system only works for the first 10 to 20 seconds of exercise with 100% effort.
It is likely that the lactic acid system would provide energy at the start of any activity, even if the intensity is not enough for the aerobic system. If you go out on a jog, most of this is powered by the aerobic system, but the start of the jog is needs to create ATP so that the heart and lungs have enough oxygen and can saturate the blood before the aerobic system can kick in. When the heart and lungs have caught up with the movement of the activity and the intensity is low enough, then the aerobic energy system can fuel the body.
In bas scenarios, such as an overweight person trying to walk up the stairs, the unfit person cannot supply enough oxygen to their body with the aerobic system. This may require a tremendous amount of effort for the individual, so they would have to use the anaerobic system without a choice. This would cause them high heart and breathing rates, they would have to take recovery periods and would produce lactic acid, as a part of anaerobic energy production

How is the phosphocreatine system effected by acute exercise?
The phosphocreatine system responds to acute exercise in a number of different ways. It is the first energy system that is used and it is the quickest energy system to recover. The energy system is anaerobic but only lasts up to ten seconds.
What effect does exercise have on the Energy System?
Suck a fat one :)
Why does your temperature go up during exercise?
Like everything else, your body isn't 100% efficient in it's conversion of energy to useful work. As you convert food to energy to do useful work, some energy is lost in the form of heat. This heat causes your temperature to rise.
What energy system is used at the beginning of exercise and during high intensity short duration exercise?
The ATP-PCr (Adenosine triphosphate-Phosphocreatine) system.
What is an example of the nervous system helping your body to maintain steady conditions?
The nervous system helps keep steady body conditions by telling the body how to respond to the information it gets. For example when you are hungry, your nervous system tells you to eat. This action maintains steady body conditions by giving your body the nutrients and energy it needs.
What are the effects of exercise on the energy system?

What are the short term effects of exercise on the energy system?
not alot tbh...
How does exercise lower blood sugars?
Exercise requires and uses up energy. The sugar/carbohydrates in your body/blood is converted to energy for this. This removes blood sugar from your system lowering blood sugar.
Steady state gain of the system?
Steady state gain,
What happens to the energy systems as the exercise continues over a 30 minute period?
when you exercise we have 3 energy systems that all start at the same time but last for different times. They are the ATC-PC system the Lactic acid system and the Aerobic system. The energy systems last different times, the ATC-PC lasts for 8-12 seconds. The Lactic acid system lasts for 3-5 minuets and the Aerobic system is an unlimited source of energy and will only run out if we lose oxygen. When the exercise period goes over 30 minuets the Aerobic system continues on its own

What is the definition of Aerobic Power?
The aerobic system, also known as aerobic glycolysis, powers continuous steady state exercise longer than three to four minutes. In the aerobic system energy (ATP) is produced through Pyruvic Acid and Lipid/Protein fragments entering the Kreb Cycle and the Electron Transport Cycle (McArdle, 1991).
