10-12 seconds
duration of ATP/PC system
1RM
Maximum amount of weight a group of muscles can lift at one time
400m event
Example of sport in which lactic energy system is dominant
absolute strength
A term for the total amount of weight you can lift or resistance you can overcome
regardless of your body weight
Adaptation
When the body gets used to a level of exercise intensity
adenosine triphosphate
a high energy compound that stores and transfers energy to body cells, allowing then
to perform their specialised functions.
aerobicprocess that requires oxygen
Aerobic glycolysis - 1 (Aerobic system)
Occurs in mitochondria (in muscle cells). Glucose (with oxygen) -> pyruvic acid ->
acetyl-coenzyme (acetyl-CoA)
Aerobic threshold
a level of exercise intensity that is sufficient to cause a training effect (approx 65%
MHR)
aerobic training zone
a level of intensity that causes the heart rate to be high enough to cause significant
training gains
Alactacid system - ATP PC – 2
ATP broken down in muscle at same time phosphocreatine (PC) is broken down
Alactacid system - PC – 3
Amount of PC in muscles is limited - depleted after 5-10s maximal work. Restored
after 2min rest
amino acids
the building blocks of proteins
anaerobic
process that does not require oxygen
anaerobic glycolysis
a process where glucose is broken down in the absence of oxygen to produce energy
anaerobic interval
Maximum effort exerted over a short distance with extended rests to allow lactic acids
to disperse
anaerobic threshold
a level of intensity in physical activity where the accumulation of lactic acid increases
quickly
anxiety
fear or apprehension in anticipation of confronting a situation percived to be
threatening
Anxiety + arousal - 1 Anxiety
, emotional response to a threat Arousal - the emotional, mental or physiological activation
required to produce a response
associative stage
identified by an emphasis on practice
ATP in the body – 3
When ATP is broken down, body cells use the energy (broken down into: ADP + P +
energy - adenosine diphosphate)
ATP PC - most readily available – 4
No long series of chemical reactions no transportation of oxygen to muscles ATP &
PC stored in contractile muscle tissue
ATP/PC
anaerobic- 5-10 seconds of high intensity work (sprints weight lifting)
autonomous stage
ability to automatically execute the skill
ballistic stretch
A repetitive bouncing movement used to stretch the antagonist muscle group. Force
by agonist muscle group or gravity. More stress on muscle than with a static stretch.
carbo loading
a regimen designed to maximize muscle glygogen stores before an athletic event
carbohydrate
A class of nutrients made of sugars; these nutrients include sugar, starch, and fiber.
All but fiber provide energy.
carbon dioxide
A waste product of aerobic glycolsis
cardiac output
Stroke Volume x Heart Rate
cardiac output
the amount of blood pumped by the heart per minute
chemical energy
energy stored in bonds between atoms
Circuit training
Sequential stations set up to stress both muscular strength and cardiovascular
endurance
closed skills
occur in an environment that is stable and predictable
concentration complete attention
concurrent feedback
feedback received during the performance of a skill
conduction
transfer of heat from a body to an object
continuous skills
skills that have no distinct beginning or end
continuous training
Aerobic activity with no break
Convection
transfer of heat by a moving fluid
cool down
an activity that prepares the muscles to return to a resting state
creatine
