Test 1 Flashcards
The flow of energy in a biological system
Bioenergetics
THe breakdown of large molecules into smaller molecules
Catabolism
THe synthesis of larger molecules from smaller molecules
Anabolism
ENergy-releasing reactions that are generally catabolic
Exergonic reactions
Require energy and include anabolic processes and the contraction of muscle
Endergonic reactions
THe total of all the catabolic or exergonic and anabolic or endergonic reactions in a biological system
Metabolism
Allows the transfer of energy from exergonic to endergonic reactions
adenosine triphosphate
Oxygen uptake above resting values used to restore the body to the pre exercise condition
EPOC
The ratio of the moment arm through which an applied force acts to that through which a resistive force acts
Mechanical Advantage
The capcity to exert force at any iven speed
Strength
The change in velocity per unit of time. This is associated with resistive force by Newtons second law. (Force=Mass X Acceleration)
Acceleration
Explosive strength. Power= Work/Time
Power
The product of force exerted on an object and the distance the object moves in the direction the force is exerted
Work= Force X Displacement
Work performed on, rather than by a muscle. During eccentric exercise
Negative Work
All of the muscle fibers in the motor unit contract and develop force at the same time
All-or-None Principle
High-intensity, intermittent bouts of exercise such as weight training, and interval training
Anaerobic training
Excesive training on a short-term basis
Overreaching
Excessive frequency, volume, or intensity of training that results in extreme fatigue
Overtraining
Decrement in performance and loss of accumulated physiological adaptations following the cessation of anaerobic training
Detraining
