This energy system provides immediate energy through the breakdown of these stored high
energy phosphates. If this energy system is 'fully stocked' it will provide energy for maximal
intensity, short duration exercise for between10-15 seconds before it fatigues -
Answers✓✓ATP-PC Energy system
adenosine triphosphate (ATP) and phosphocreatine (PC).
ATP-PC (phosphagen system, anaerobic glycolysis system (lactic acid) and aerobic (oxygen )
system - Answers✓✓What are the bodys 3 sources of ATP
Every muscle cell has some amount of ATP. Adenosine triphosphate (ATP) is the way your
body uses biochemicals to store and use energy. There is enough ATP in the cell that the muscle
can use immediately, but only enough to last for about three seconds. The muscle must
replenish the ATP levels quickly, using a high-energy phosphate compound called creatine
phosphate.
An enzyme called creatine kinase removes the phosphate group from creatine phosphate and
transfers it to ADP to form ATP. The cell then turns ATP into ADP, and then the phosphagen
turns the ADP back into ATP. The muscle continues to work, and the creatine phosphate levels
begin to decrease. The ATP levels and creatine phosphate levels working together are called the
phosphagen system. This phosphagen system supplies the energy needs of working muscle, but
only for 8 to 10 seconds. - Answers✓✓Phosphagen System
ATP production during high intensity, short duration exercise *provides energy for up to 15 sec.
- Answers✓✓What is the phosphagen system used for ?
-Major supplier of ATP *Stored glycogen is split into glucose and than into pyruvic acid. - the
energy released is ATP.
-results in formation of lactic acid
*Does not require o2
-Only uses carbohydrates (glycogen and glucose)
-Releases enough energy for the resynthesis of only small amounts of ATP. -
Answers✓✓Anaerobic Glycolysis -
high intensity, short duration exercise - Answers✓✓Anaerobic glycolysis system supplies ATP
during what?>
used during low intensity, long duration exercise such as running a marathon.
*Yields the most ATP but required complex chemical reactions
*This system will provide energy as long as there are nutrients to utilize. - Answers✓✓Aerobic
metabolism
low intensity, long duration activities, - amount of ATP production is greaters but requires a
complicated series of chemical reactions - Answers✓✓Aerobic system supplies ATP during ?
Anatomical Position - Answers✓✓Erect posture of the body with the face forward, feet pointing
forward and slightly apart, arms at the side, and palms forward with fingers and thumbs in
extension .
Frontal -divides body into anterior and posterior sections Ex: Abduction and Adduction
sagittal - Divides body into right and left sections Ex: Flexion and Extension
transverse -divides body into upper and lower sections Ex: medial and lateral rotation -
Answers✓✓3 cardinal planes of the body
*Provides SLIGHT motion
-2 bones covered with hyaline cartilage and connected by fibrocartilage -
Answers✓✓Symphysis
Uniaxial joint
biaxial joint
multi-axial joint - Answers✓✓3 Types of synovial joints
diarthroses - Free movement - Answers✓✓another name for synovial joints
*Provide what type of movement?
Synovial - Answers✓✓Which joints are them most complex and vulnerable to injury?
joint cavity, articular cartilage, snynovial membrane, synovial fluid and fibrous capsule -
Answers✓✓Synovial joints have 5 distinguishing characteristics. what are they?
one motion around a single axis in one plane of the body
Ex: Hinge - elbow
Pivot - atlantoaxial joints - Answers✓✓Give 2 examples of an uniaxial joint
Movement occurs in 2 planes and around 2 axes through the convex/concave surfaces.
-Condyloid- metacarpophalangeal joint of finger
-Saddle - carpometacarpal joint of the thumb - Answers✓✓Biaxial joint
movement occurs in 3 planes and around 3 axes
Ex: plane (gliding)- carpal joints
ball and socket - hip joint - Answers✓✓Multi-axial joint
