Energy Systems
This system provides energy for the first 10 seconds of maximal activity.
What is the ATP-PC system?
This term describes the maintenance of internal balance.
What is homeostasis?
This principle explains why training effects decrease without continued stimulus.
What is reversibility?
This law states force = mass × acceleration.
What is Newton’s Second Law?
This type of skill involves predictable, stable environments.
What is a closed skill?
This system is dominant in a 400m sprint event.
What is the lactic acid (anaerobic glycolytic) system?
This is the name for the maximum amount of oxygen an athlete can use.
What is VO₂ max?
This principle refers to training being relevant to the sport or skill.
What is specificity?
The point at which torque is maximized in a lever system.
What is the second-class lever?
This stage of learning is where learners rely heavily on external feedback.
What is the cognitive stage?
This process allows carbohydrates to be broken down with oxygen for energy.
What is aerobic glycolysis?
These two physiological responses increase linearly with exercise intensity.
What are heart rate and stroke volume?
This principle explains how training must become harder as the body adapts.
What is progressive overload?
The biomechanical term for the resistance to angular acceleration.
What is moment of inertia?
This type of transfer occurs when practice in one sport helps another.
What is positive transfer?
This metabolic byproduct contributes to fatigue in anaerobic conditions.
What is lactic acid (or H⁺ accumulation)?
This term refers to the oxygen debt post-exercise.
What is EPOC (Excess Post-exercise Oxygen Consumption)?
This principle ensures appropriate balance of work and rest.
What is the principle of recovery?
This describes the force that causes rotation around an axis.
What is torque?
This term refers to practicing multiple skills in varied order.
What is random practice?
This cycle describes how acetyl-CoA is oxidized in aerobic respiration.
What is the Krebs cycle (or Citric Acid Cycle)?
This effect occurs when heart rate increases before exercise due to anticipation.
What is the anticipatory rise (or pre-exercise heart rate increase)?
This term describes small, regular increases in training load to avoid plateaus.
What is progressive loading (or periodization)?
This biomechanical principle explains how spin affects trajectory.
What is the Magnus effect?
This theory suggests we store general rules for classes of movement.
What is Schmidt’s Schema Theory?
