Nasm Terms 3 Flashcards
1
Q
Concentric
A
Muscular force greater than resistive force, muscle shortens
2
Q
Eccentric
A
Muscle develops tensions while lengthening, deceleration
3
Q
Isometric
A
Muscular force equal to resistive force, no change in muscle length
4
Q
Aerobic
A
Requires oxygen
5
Q
Anaerobic
A
Without oxygen
6
Q
Adenosine triphosphate
A
Energy storage and transfer unit within cells
7
Q
Anaerobic threshold
A
where the body can no longer produce enough energy with normal oxygen intake.
8
Q
ATP-PC
A
- anaerobic
- High intensity
- lasts 10-15 secs
9
Q
Glycolysis
A
- anaerobic
- moderate to high intensity
- up to 30- 50 Secs
10
Q
Oxidative System
A
- Aerobic glycolysis
- Krebs cycle
- Electron transport chain
- Long-term energy
11
Q
Muscle spindle
A
sense changes in muscle length.
12
Q
Joint receptors
A
respond to pressure, acceleration, and deceleration of joints
13
Q
Golgi tendon organ
A
sense changes in muscular tension
