Definitions Flashcards
What is aerobic work?
Working at a moderate intensity so that the body has time to use oxygen for energy production.
Examples include long-distance events and continuous activities.
Define fitness.
The ability to meet the demands of the environment.
Fitness allows the body to work for a continuous period.
What is fixed practice?
Repeatedly practising a whole skill within a training session.
This method is often used for skills like long-distance running.
What does anaerobic work entail?
Working at a high intensity without oxygen for energy production, resulting in limited energy and shorter work periods.
An example is sprinting.
What is the frontal axis?
An imaginary line passing horizontally through the body from left to right, which allows flexion and extension.
Define the frontal plane.
An imaginary line dividing the body vertically from front to back.
Movement occurs in the frontal plane about the sagittal axis.
What are antagonistic muscle pairs?
Pairs of muscles that work together to bring about movement; as one muscle contracts (agonist), the other relaxes (antagonist).
Example: biceps and triceps.
What does gamesmanship refer to?
Bending the rules/laws of a sport without actually breaking them.
What is an axis in anatomical terms?
A line around which the body or body part can turn.
Define guidance in skill learning.
Information to aid the learning of a skill, which can be given visually, verbally, manually, or mechanically.
What is a basic skill?
A simple skill requiring little concentration to execute.
What characterizes a closed skill?
A skill performed in a predictable environment.
Example: a player taking a penalty in football.
Define health.
A state of complete emotional, physical, and social wellbeing, and not merely the absence of disease and infirmity.
What is a complex skill?
A skill requiring a lot of attention and concentration.
What is deviance in sports?
Behaviour that goes against the moral values or laws of the sport.
Define high organisation skill.
A skill that cannot be broken down easily and practiced separately because the phases of the skill are closely linked.
What is distributed practice?
Skill practice with intervals within a training session for rest or mental rehearsal.
What is hydration?
The process by which water is ingested and absorbed into the body.
Define exercise.
A form of physical activity done to maintain or improve health and/or fitness - not competitive sport.
What is energy balance?
Balance between energy input (via food) and energy expenditure.
What is lactate accumulation?
When lactate levels in the blood/muscle rise due to increased work intensity.
What is feedback in a performance context?
Information received during or after a performance about the performance.
What is lactic acid?
A by-product of energy production, formed when the body is exercising anaerobically at high intensity.
Define lever in biomechanics.
A rigid bar that rotates around a fulcrum to apply a force to a load.
