What is Exercise physiology?

the study of the functional and physiological response and adaptations that occur during and following physical activity and exercise

What is a exercise physiologist concerned with?

how the systems individually and collecting respond to acute and chronic bouts o physical activity and exercise

What are some examples of acute responses?

eyes blink


HR Spikes



comes or slows down quickly

What are some examples of chronic response?

Exercising over a period of time which causing a increasing in the amount of blood is pumped into the system

We can increase our max HR with training but

we can get better at pumping blood

Increase of HR SV CO BP



Acute or Chronic?


What system?

Acute


Cardiovascular System

Increase in air movement and increase blood flow through lung



Acute or Chronic?


What system?

Acute


Pulmonary System

Increase in force production, utilization and production of energy and heat production



Acute or Chronic?


What system?

Acute


Muscular System

Increase in the release of epinphrine (Fight or Flight response) and norephinephrine



Acute or Chronic?


What system?

Acute


Endrocine System

Heart even at rest pumps more blood with every beat



Acute or Chronic?


What system?

Chronic


Cardiovascular System

Improved air movement



Acute or Chronic?


What system?

Chronic


Pulmonary System

HR Max = 200 beat/min



SV Max = 50 mL/beat



What is CO?

10,000 mL/min

HR Max = 200 beat/min



SV Max = 100 mL/beat



What is CO?

20,000 mL/min

Areas of Study

-metabolism


-muscle control


-skeletal muscle physiology


-bone metabolism

Factors controlling substrate

Interaction of fat and carbohydrate utilization



Effects of intensity and duration



Role of enzymes and hormones

Is there a fat burning zone?

No, it matters how many calories you burn during exercise there is no magical fat burning zone

lower intensity

last longer

higher intensity

doesn't last long

cortisol hormone?

stress hormone

what to isolate a system?

improve a performance

muscle control of glucose uptake

body closely regulates energy utilization during physical activity and exercise



movement of glucose from the blood into the cell depends on the glucose transport protein



store glucose as glycogen and is stored in muscle and liver

blood sugar level to remain constant in the blood by getting it from the?

Liver "the warehouse" and once the blood is low the liver breaks down and introduces glycogen to the blood

Insuline binds to?

the skeletal muscle and protein receptors come out and grab more sugar out of blood

skeletal muscle physiology

fibers have distinct contractive and metabolic characteristics



train results in fibers taking on characteristics that help the requirements of the physical activity or exercise

restistance train?

muscle hypertrophy cant change who you are naturally

bone metabolism

influence by physical activity and exercise



osteoporosis


-characterized by loss of bone mineral density decreases


-increased risk of bone fractures



-need bone stress to improve growthFe

Female athlete Triade

- eating disorder


- hypotralamic Amenorrhea


- Osteoporsi

Eat disorder is classified as?

over eating



under eating
