25
what is psychology important for enhancing movement
- leads to many benefits for hauora - gets people doing PA - the problem of not PA is not not knowing the benefits but is getting people to actually do it
26
enhancing movement for performance =
getting people to do it by a behaviour change
27
myth: education leads to a behaviour change
truth: changing our behaviours to adopt and maintain PA is complicated. trying to convince people of its importance isn't enough
28
% of NZ that agree that being active in important and % for mental and emotional support
91% 88%
29
% of NZ that don't achieve PA guidelines % that drop out in the first 6 months
50% for both
30
motivation definition and how it effects behaviour
anything that impels a person into actions, which we are shown through intensity and direction of the behaviour - behaviour change starts with having motivation
31
Motivation for PA
comes from outcome expectations - what is PA going to achieve for us - this is what helps us start doing PD - influenced by when outcomes will be achieved, proximal or distal
32
PA proximal or distal achievements
proximal - occurs during or shortly after exercise eg. happy or sore muscles distal - expected days or months after continued exercise
33
distal outcomes impacts
this is our day to day motivation, but we are less likely to recognise these outcomes, because we rank them as less important. but these are what is needed for long term motivation/aspiration.
34
high expectations and high experienced outcome
optimistic realist
35
low expectations and high experienced outcome
surprised pessimists
36
high expectations and low experienced outcome
disappointed optimist
37
low expectations and low experienced outcome
pessimistic realists
38
unexpected outcomes of PA lead to
motivation
39
we can't give people motivation they need to ...
appreciate and value the outcomes for themselves
40
what are the two types of motivation
autonomous controlled
41
autonomous motivation
i enjoy exercise and value it which leads to PA adherence and positive psych wellbeing
42
controlled motivation
i have been told to exercise and will feel guilty if I don't leads to short term adoption of PA and negative psych wellbeing
43
myth: more motivation is better
truth: the quality of motivation is more important
44
to get a person from controlled to autonomous motivation
they decide - decrease the pressure and get him involved they belong - help them feel a sense of connection to the exercise environment they can do it - increase their confidence, to help him realise the can do it
45
changing behaviour requires
confidence - ones ability to exercise and achieve a particular outcome
46
how do we build confidence
1. create accomplishments so people learn what they can achieve 'i did it before so I can do it again' eg. goals 2. provide supportive feedback that reinforces achievements, needs to be specific and that they are in control of 3. create situations where people can see others being successful eg. exercise in groups
47
myth - people can meet PA guidelines if they really want to
truth - behaviour change is complicated
48
affect response (general feeling state)
affect - is a general overview of how you feel, takes into account our moods and emotions affect response - how we feel in result of a stimulus eg. negative affect = feeling bad eg. positive affect = feeling great
49
how can we measure psychology factors of exercise
we can't directly measure so we have to do it indirectly and use subjective measures eg. have to ask people, eg using the feeling scale or RPE for example
50
why does affect matter
- it is a component to psychological well-being - its a motivational force therefore affective response to exercise - how did i feel after it yday. - how am i going to feel = exercise decision
51
what is the motivational force
people chose to do things that make them feel good and avoid what makes them feel bad
52
its not how we feel after is after exercising that impacts motivation it is
how we feel whilst we are exercising
53
influence of exercise intensity on affect
- exercise intensity has the strongest influences on how we feel during exercise CURRENT RESEARCH SHOWS - - after exercise we feel better than before we did it - there is no universal exercise intensity that will produce the most positive affect during exercise in all individual - it is complicated - 2. is because everyone has different cognitive appraisal for generating affective response at moderate intensities - so cognitive appraisal will different with exercise experience - at high intensities, physiological symptoms dominate and make us feel horrible
54
cognotive appraisla on affect response
everyones is different as we all perceive it different - psychological symptoms - psychological factors (motivations/ability)
55
importance of cognitive appraisal
then their cognitive appraisal 'should' lead them to choose an intensity that makes them feel good/get most physiological benefits - this is proved by evidence don't prescribe intensity - let them chose to get the most benefits, and remind them to make them feel good to further increase positive affect
56
does/should exercise have to hurt to be worthwhile
no and no
57
all sport technology wearable devices is not always
useful, it depends on what you are trying to measure
58
acceleromterters
measures linear acceleration along 3 axes
59
gyroscopes
measures rate of rotation of device, 3 axes measure using orientation
60
electrocardiography
- recording of hearts electrical activity - voltage measured through electodes P wave - atrial depolarisation QRS - ventricle depolarisation T wave - ventricle depolarisation this is the gold standard
61
Heart rate and variability
is an ave number of beats/min and is a frequency heart rate variability at rest indicates healthy exchange between SNS and PSNS
62
applications of in the wild training monitoring
- synchronisation of physiological and biomechanics systems - by step and by heart rate
62
PPG - photoplethysmopgraphy
measures HR - light reflects off skin and is measured by the sensor, in which heart rate is inferred from blood flow through measured region so is an indirect measure - not accurate during exercise
62
vagal tone
activity of the nagus nerve, decreases on inhale and increase on exhale
63
markerless motion capture
- full body 3D model - location of body landmarks - not fully portable - accurate in 4 degrees for sagittal movement (so pretty good) - cheap and fast
64
estimating energy expenditure (step counting)
use pedometer or accelerometers - steps are easy to understand - they aren't the only use of daily energy use
65
pros of wearables
- reasonably a good indication of activity - can be used to monitor activity - can increase activity from sedentary - can be motivating - being active tends to lead to other good habits
66
cons of wearables
- can be expensive - can lead to extrinsic motivation - setting activity goals can be gamed - goals not validated - beholden to device
67
beholden to device
- less likely to not exercise if not wearing them - feeling guilt when not active - metrics can affect perceptions of how you feel
68
technique analysis
an application of biomechanics, practically orientated which is usually done on the field, and normally involves qualitative analysis with basic equipment. normally only look on one athlete - mainly video - sensor, markerless which are cheaper and faster
69
when it comes to amount of data in analysis more is not always
better
70
workflow of the technique
1. develpo a model of the movement or the game, rg what needs to be worked on 2. model should simplify movement but retain important features = must be good at 3 3. decide on goal and focus of analysis 4. observe and evaluate the movement
70
running cadence and breathing rate graph
soccer - as you run faster and your cadence increases your breathing rate increase but runner stays prettier similar as your speed increases
70
notational analysis
an objective method of describing and recording games and events - helps the coach to remember what happened - strategies - assess physiological demands - entertainment
70
performance analysis
technique is apart of this
71
the brain is energy ....
thirsty (21%), but also has both chronic and acute changes with exercise
71
experience-dependent plasticity of the brain
- synaptic pruning - long term potentiation - selective inhabitation - myelination (fatty surrounding to speed up signals)
71
workload analysis
- now popular with GPS introduction - this is when intensity and volume of activity is in interest
72
popularisation of accelerated learning
- life hacks - speed learn skills but they may not be beneficial do it as may not have the time or energy but have positive impact as helps us understand the science of learning and about the evolving world
73
4 ways to get people more confident to do PA
- set appropriate goals - create effective plans - feedback - see others being successful
74
affect has the power to .....
motivate
75
what has the strongest influence on how we feel during exercise
exercise intensity
76
what 3 external things do technology use
- ground/impact forces - linear and angular forces - joint torques/movements
77
technology on HR
is not vary accurate as they measure the variability of the HR
78
6 sport classifications
- track/field/racing - invasion games (rugby) - net/wall games - batting games - target games (golf) - aesthetic orientated (diving)
