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 |
