Exercise physiology is the physiology of physical exercise, it is the study of the acute responses and chronic adaptions to a wide range of exercise conditions (Rickett, 2016). Exercise physiology is simple understanding of how the body responds to exercise and how the human body moves. Exercise physiology examines how your body cells and organs such as cardiovascular, muscular and respiratory systems are changed when exposed to short or long bouts of exercise
. While sports physiology is the study of how exercise alters the function and structure of the body. In sports physiology it looks to understand the physiological demands of a sporting performance which notifies what characteristics an athlete should have to be successful when competing at the highest level.

Get Help Now!When examining the acute response to exercise we are concerned with the body’s immediate response to and sometimes its recovery from a single exercise bout. Acute exercises are meant to be less strenuous exercises for a shorter amount of time. For example, thirty minutes of basketball shows acute responses when a player is running up and down the court, as well as trying to block and pass the ball. Acute responses are the body’s immediate response to exercise such as an increase in heart rate and body temperature. For an acute response during resistance exercise the baseline intensity and volume must be met, higher intensity extracts more response.
Adenosine Triphosphate (ATP) is a triphosphate used in cells as a coenzyme for intracellular energy transfer (Karp, 2013). Humans produce ATP through three metabolic pathways that consist of many enzymes catalyzed chemical reactions. This energy system provides immediate energy through the breakdown of the stored high energy phosphates. The anaerobic system is made up of a systems of high energy phosphate and anaerobic glycolysis (Karp, 2013). This system produces a lot of power but not quite as much or as quickly as the ATP- PC system. It does have a larger fuel supplies and does not burn all its fuel as quickly as ATP-PC system. By about 30 seconds of sustained activity most of energy comes from an anaerobic system at 45 seconds of sustained intense activity is a second decline which anything above this relies on the aerobic energy system. The aerobic system produces far more ATP than either of the other energy systems, but it produces the AT much slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP. Therefore, it cannot fuel intense exercise that demands the fast production of ATP.

Exercise physiology is the scientific study of the body’s response to different levels of physical activity. It builds from the physiology study of the body and metabolic function. Exercise physiologists focus on how exercise, or inactivity, affect body systems such as the cardiovascular system or skeletal muscles (Bloomer, 2010). An exercise physiologist may focus on research, work in clinical settings or in exercise testing labs (Bloomer, 2010). A sports physiologist focuses more on the physiological demands of sport performance on the body in order to improve physical performance. Sports physiologists usually have careers as athletic trainers, health educators, coaches, or fitness trainers.
The acute responses to a single bout of exercise refers to the initial changes in the body systems during the moment of exercise. An example of this would be the increased rate of breathing during a run.
The three energy systems are the ATP PCr system, lactic acid system, and oxidative system. The ATP PCr system is characterized by how fast it occurs-it lasts about 10 seconds. Energy is provided immediately from adenosine triphosphate (ATP) and phosphocreatine. This energy system is anaerobic, meaning it does not need oxygen to occur, and it happens in the muscles sarcoplasm (East ATP, 2014). The lactic acid system is also anaerobic, but it is longer lasting than the ATP PCr system-usually lasting 30 seconds to 3 minutes (pdhpe.net, 2015). In the lactic acid energy system ATP is produced by the breakdown of glucose in the muscle cells. The oxidative energy system is an aerobic system, meaning it needs oxygen in order to produce energy and only occurs in the mitochondria (East oxidative, 2014). This is the system most commonly used for rest and low intensity exercise and usually begins around 2-3 minutes into exercise.

I am a 35-year-old father of a beautiful 8-year-old autistic daughter and husband of six years, although my wife and I have been together of almost fourteen. While I have never served in the military, myself, my grandfather served in the army, my father and one of my brothers served in the navy and a brother and sister in law are currently serving in the air force so my family is very steeped in military service. I am a born and raised Floridian, I have spent 33 of my 35 years living on Florida’s east coast, with 2 years living in central Florida while I was finishing up my bachelor’s Degree at the University of Central Florida (#Chargeon! Knights). I am currently enrolled in the last three classes I need to fulfill as pre-requisites in order to apply to a Doctor of Physical Therapy program, and with any luck I’ll end up with a 4.0 average on my final three classes, so I have a 4.0 on all my pre-reqs and get into the program. Sports Psychology is a required course, this is true, but this is one of the few required pre-req courses I am actually excited to be enrolled in. As a future physical therapist, I feel like being able to dig deeper into the mind of someone under my care and help motivate them to want to improve and get over any objections they may have will be infinitely valuable. In addition to this, sports have always had a large role in my life. I grew up playing sports and did so into my early 30’s. I have also coached youth sports before and hope to do so again, being able to communicate with youth athletes on a level that motivates and inspires them to succeed will be a great tool.
