Subject specific vocab Flashcards
What is altitude training? (A&P)
Training at altitude where there is less oxygen. The body adapts by making more red blood cells to carry oxygen. These additional red blood cells are an advantage for endurance athletes returning to sea level to compete
What is a anticipatory rise? (A&P)
An increase in heart rate prior to exercise, due to the release of adrenalin.
What are articulating bones? (A&P)
Where two or more bones meet to allow movement at a joint.
What is arterio-venous oxygen difference (A-VO2 diff)? (A&P)
The difference in the oxygen content of the blood between the arterial blood and the venous blood.
What is an axis? (A&P)
Imaginary line through the body around which it rotates.
What are the three type of axis? (A&P)
1) longitudinal
2) transverse
3) sagittal
What is a longitudinal axis? (A&P)
Head to toe
What is a transverse axis? (A&P)
Through the hips
What is a sagittal axis? (A&P)
Through the belly button
What is the cardiac conduction system? (A&P)
A group of specialised cardiac muscle cells in the walls of the heart that send signals to the heart muscle, causing it to contract.
What are the main components of the cardiac conduction system? (A&P)
The SA node
AV node
Bundle of His
Purkinje fibres
What is the excess post-exercise oxygen consumption (EPOC)? (A&P)
Increased rate of oxygen intake following strenuous activity, intended to pay back the oxygen deficit
What is indirect calorimetry? (A&P)
A technique that provides an estimation of energy expenditure from the amount of carbon dioxide produced and oxygen consumed during rest and steady-state exercise.
What is lactate-producing capacity? (A&P)
The capacity to produce high levels of lactate during exercise.
What is a lactate threshold? (A&P)
An abrupt increase in blood lactate.
What is a oxygen deficit? (A&P)
The difference between the oxygen required during exercise and the oxygen supplied and utilised. Occurs at the onset of exercise.
What is a plane? (A&P)
Imaginary lines depicting the direction of movement.
What the three types of plane? (A&P)
1) transverse
2) frontal plane
3) sagittal
What is a transverse plane? (A&P)
Rotation around the longitudinal axis
What is a frontal plane plane? (A&P)
Left or right
What is a sagittal plane? (A&P)
Forwards and backwards
What are receptors? (A&P)
Part of the nervous system that detects changes in the body
What are the three types of receptor? (A&P)
1) Baroreceptor
2) Chemoreceptor
3) Proprioceptor
What is the respiratory exchange ratio (RER)? (A&P)
The ratio of carbon dioxide produced to the oxygen consumed.
What is a VO2 max? (A&P)
The maximum amount of oxygen that can be taken in, transported and used by the body per minute.
What is VO2 max measured in? (A&P)
Measured in millilitres for each kilogram body weight each minute (ml/kg/min)
What is acceleration? (ES)
The rate of change of velocity or the difference between final and initial velocities divided by the time taken.
What is a acute injury? (ES)
Sudden event where the cause and onset of pain are identifiable, eg fracture, sprain.
What is a chronic injury? (ES)
Also known as an overuse injury which occurs over time, eg Achilles tendonitis, stress fracture.
What is drag? (ES)
The dynamic fluid force component that acts in opposition to the motion of an object with respect to a fluid, air or water.
What is high intensity interval training (HIIT)? (ES)
An exercise strategy alternating periods of short intense anaerobic exercise with less-intense recovery periods.
What is a impulse? (ES)
The effect of a force acting over a period of time. Force multiplied by time. It is also a change in momentum. Impulse is measured in newtons per second (Ns) reduced to kg/s.
What is a lever? (ES)
A rigid bar (bone) that turns about an axis to create movement. The force to move the lever comes from muscle/muscles.
What does a level contain? (ES)
Fulcrum - fixed point, effort (from the muscle/s to move it)
Load/resistance (from gravity).
What is a lift? (ES)
The dynamic fluid force component that acts perpendicular to the relative motion of an object through a fluid, air or water.
What is momentum? (ES)
The quantity of motion of a body. Mass multiplied by velocity.
What is a objective? (ES)
Based on empirical data, eg times, scores.
What is reliability? (ES)
Relating to the consistency and repeatability of a test.
What does qualitative mean? (ES)
More of a subjective than an objective appraisal. Involving opinions relating to the quality of a performance rather than the quantity.
What does quantitive mean? (ES)
A measurement which can be quantified as a number, eg time in seconds, or goals scored. There is no opinion expressed (qualitative). It is a fact.
What does scalar mean? (ES)
Quantities have only magnitude (size).
What is speed? (ES)
The distance covered by a moving object in unit time taken. Distance divided by time.
What does subjective mean? (ES)
An impression or judgement on how well a test was performed.
What does validity mean? (ES)
The extent to which a test or method measures what it sets out to measure.
