Random Mrs Rex stuff Flashcards
Word for when not enough O2 at the start of exercise to fully aerobically respire?
Submaximal deficit
What is anaerobic capacity, another word for it?
Max amount ATP resynthesised by anaerobic respiration, Maximal accumulated O2 deficit (MAOD)
Components of EPOC, what happens in each and for how long?
Alactacid (fast component) - O2 replen to resaturate myoglobin (2min), PC and haemoglobin
PC replen- 30seconds 50%, 3min 100%
Lactacid (slow component)- lactic acid removed
How is lactic acid removed? How long does it take
Lactacid stage (slow component)
.Converted into pyruvic acid and oxidised into co2 and h2o if o2 present
.transport via blood to liver, convert to glycogen
. Convert to protein
.Remove by sweat/urine
50% take half an hour, 100% many hours
Methods to measure energy consumption, how?
Indirect calorimeter, measure co2 production at rest/exercise, indicate vo2 max, lots of equipment
Lactate sample
VO2 max test by multi stage fitness test
RER, compare o2 consumed to co2 produced
Stages of plyometric
.Eccentric (pre stretch), muscle lengthen under tension storing elastic energy
.Amortisation time between leg bending and contracting to jump. Should be as short as possible
.Concentric, muscles contract and stored energy used to force athlete off the ground
Factors that affect lactate threshold
Exercise intensity, muscle fibre type, rate of lactate removal, RER and fitness
MAOD meaning
Maximal accumulated oxygen deficit (anaerobic capacity)

What causes horizontal shoulder abduction
Latissimus Dorsi
What is the antagonist in horizontal shoulder abduction
Pectoral
What causes shoulder addiction
Posterior deltoid
What causes shoulder abduction
Supraspinatus and middle deltoid
Other name for hip flexor
illiopsoas
Causes of learning plateau
Many bees can look toward flowers
Who are the 4 learning theorists, what do they do
Bandura- SLT observational learning
Vygotsky- Social development theory Constructivism
Gestalt- cognitive, insight learning
Skinner- behaviourism operant conditioning
Explain Gestalts theory
Cognitive, Insight learning, sudden realisation based on past experiences
Explain vygotsky theory
Social development theory Constructivism, learn by MKO, inter and intra, zone of proximal development to asses (what I can do, what I do with help, what i can’t do)
What are newtons laws, explain
Inertia, in order to change objects state of motion an external force is required to overcome its inertia (resistance to change in motion)
Acceleration, A x mass = force, the magnitude and direction of a force will determine the direction and magnitude of the acceleration
Action Reaction, Ground reaction force
4 internal consequences of smoking
Inflammation in respiratory system cause narrowing
Carbon monoxide bind to Hb
Reduced alveoli SA
Cilia damage cause coughing due to mucus build up
Chronic obstructive pulmonary disease
Type 1 muscle name and characteristics
Slow oxidative, small motor neurone, lots of mitochondria myoglobin and capillary
Type a and b muscle name and characteristics
A- fast oxidative glycolytic
B fast glycolytic, large motor neurone bodies, opposite to slow oxidative
Methods to increase muscle contraction strength
Higher frequency, recruit type 2b and large motor units
What is wave summation
Repeated nerve impulse that doesn’t allow time for full muscle relaxation, therefore contraction gradually increases in strength
Definition of spatial summation
When multiple motor units are recruited at different times to make a sustained contraction, shares work load so individual motor units don’t fatigue
Location and function of Golgi apparatus
Between tendon and muscles. Detect muscle tension in isometric contraction cause autogenic inhibition
What is autogenic inhibition
The sudden relaxing and lengthening of muscles in respond to isometric contraction. Caused by Golgi tendon organ
Centre of mass definition
Point of balance
How to increase stability (4)
Line of gravity over support base
Increase weight (more inertia)
Increase area of base support
Lower centre of mass
Where are each leaver found?
1 overheard throw in, neck extension/flex
2 plantar flexion
3 all other joints
Mechanical advantage of lever 1
Depends on the distance of the fulcrum from resistance/ effort
Generally large range, fast, weak
Enzyme used to convert glycogen and glucose
Glycogen phosphorylase
Explain what happens in glycolysis
Glucose and PFK make pyruvic acid, oxidation occurs turning it to 2 Aceltyl groups and produces CO2
What happens to citric acid in the kerb cycle?
Oxidative phosphorylation turns it to H which is carried to the ETC
Components of the decisions making
Detection
Comparison
Recognition
What is the translators mechanism
Input is compared to already coded info so decision can be made
Whitings model explain
Input from display Receptor system Perceptual mechanism (filter) Translatory mechanism Effector system Output
Who believes core principles are used and adapted to specific stimulus
Schmidt
Components of Schmidt schema model
RECALL SCHEMA: Initial condition (info from display) Response spec (choose what to do) ACTION RECOGNITION SCHEMA: Sensory consequence (feel) Response outcome (feedback of result)
What is after the AVN?
Bundle of his then bundle branches
Methods to increase memory (6)
Focus Reward Repetition Motivation Chunking Chaining
What controls BP and shunt mechanism
Vaso motor centre in the medulla oblongata
Causes for hicks law
Single channel hypothesis (one stimuli at a time)
Psychological refractory period (delay when processing 2nd stimuli due to 1st still being processed)
