25
Subjective
refers to personal perspectives, feelings, or opinions entering the decision making process
26
Cohort Study

27
Ecological Study
assess correlation between exposure and disease at a population level Strenghts -Inexpensive Weaknesses -can only assess correlation, not causation
28
Ecological Fallacy
Making inferences about an individual based on population level data
29
Randomized Control Study
Participants are randomly assigned to an intervention group or control group and the groups are assessed for an outcome variable of interest Strengths - randomness can reduce biasses Weaknesses -controlled in a lab so results don't reflect real world conditions
30
What is Physical Activity?
Voluntary movement carried out by skeletal muscle that requires more energy than the amount of never needed at crest and is focused on building health -ex yard work, walking to school
31
What is exercise?
Planned, structured and repetitive movement pattern intended to improve fitness -ex high intensity training, resistance training
32
What is fitness?
The ability to carry out tasks with the visor and alertness, without undue fatigue and with ample energy to enjoy leisure time pursuits and meet unforeseen emergencies -ex muscular strength, flexibility
33
Cardiorespiratory Endurance
The ability to carry out prolonged, large muscle, dynamic movements at a moderate to high level of intensity. When heart is pumping blood and lungs are pumping oxygen.
34
Muscular Strength
The ability if the muscles to exert force over a single or maximal effort
35
Muscular Endurance
The ability of the muscles to exert force over a single or maximal effort
36
Flexibility

37
Healthy Body Composition
`The relative amount of fat mass to fat free mass
38
The overload principle
Adding more stress to the system in order to stimulate improvements
39
The FITT principle
Frequency: how many sessions? Intensity: How heavy is the weight? Fast pace? Time: How long does it last? Type: That are the PA components? Frequency+ Time = performance
40
Progression Principle
Implied that for someone to improve fitness levels, they must continue to increase physical demands to reach optimum level of overload.
41
Principle of reversibility
Activity must continue at the same level to maintain the same level of adaption
42
Detraining
As activity declines, called detraining, adaptions with recede
43
The Early Years (0-4)
- 180 Minutes a day - tummy time, crawling, playing outside etc - building healthy hearts, developing self confidence
44
Children (5-11)
- 60 Minutes of moderate- high intensity 3 days a week - bike riding, playground, activity that cause sweat and high breathing - do better in school, grow stronger, improve health and fitness
45
Youth (12-17)
- 60 minutes of moderate to high intensity 3 days a week - bike riding, skating, sweating and high breathing - have fun w friends, happier etc
46
Adults (18-64)
- 150 minutes of moderate to high intensity in interval of 10 minutes or more 2 days a week - jogging, skiing, sweating and breathing harder - to prevent: high blood pressure, disease, mental health
47
Seniors (65+)
- 150 minutes of moderate to high intensity in interval of 10 minutes or more 2 days a week - swimming, walking - maintain mobility, bone health,
48
Transtheoretical Model (TTM)
To understand when people change behaviours; in particular, addictive behaviours such as smoking, drug use and alcohol abuse
49
Stages of TTM
1. Pre-contemplation 2. contemplation 3. preparation 4. action 5. relapse 6. maintenance
50
Pre-contemplation
6 months before people start thinking about behavioral change (ex. uninformed that PA increase quality of life)
51
Contemplation
people recognize there is a problem and have started thinking about change (ex. pros and cons of PA)
52
Preparation
Decision has been made to change | ex buying running shoes or signing up for the gym
53
Action
6 months of implementing the plan or putting them into action (ex following exercise program)
54
Maintenance
continues for 6 months after action period and continue to stay active
55
Relapse
when people go back to old behaviours
56
Consciousness raising
the process whereby people obtain information about themselves and the problem behavior
57
Dramatic Relief
expressing feelings about or reacting emotionally to the behaviour change in question
58
Environmental re-evaluation
looking at the behavior being changed in light of its impact or effect on the physical and social environments (parents exercising with their kids)
59
Social Liberation
the process whereby options or alternatives are sought that support new behavior (looking for a house near a park to engage in PA)
60
self re-evaluation
process in which people look at themselves with and without the problem behaviour and assess the differences in their self esteem (feeling better after the gym)
61
Stimulus control
when people remove the cues or triggers for the problem behavior from their environment
62
counter conditioning
substituting a healthier behaviour for the unhealthy one
63
Helping relationships
relationships with people who act as a support system for changing the unwanted, unhealthy behaviour
64
Reinforcement management
rewarded or punishing yourself for complete a task
65
self-liberation
entails people choosing to change their behavior and committing to making the change. (running to work rather than driving to work
66
Immediate/ Explosive Energy Sources
- first responder | - provides ATP for the first 10-20 seconds
67
Non-Oxidative (Anaerobic) Energy System
uses glucose to produce ATP without the help of oxygen
68
Oxidative (Aerobic) energy system
- oxygen+cellular fuel = ATP | - slowest to arrive but lasts the longest
69
3 ways to measure intensity
1. HR 2. Rating of Perceived Exertion 3. Talk Test
70
Calculating Max HR
207-0.7(age)
71
Isometric contraction
a static contraction where the length of the muscle or the joint angle does not change
72
Isotonic contraction
a moving/ dynamic contraction where the muscle length changes and there is movement at the joint
73
Concentric contraction
contraction causes the muscle to shorten
74
Eccentric contraction
when the muscle lenghtens
75
Slow-twitch Oxidative Fibers
- red muscles - slow contraction - fatigue resistant - oxidative energy production
76
Fast-Twitch Oxidative
- red muscles - moderate contraction - fatigue resistant - glucose store energy production but becomes oxidative
77
Fast-Twitch Glycolytic
- white muscle - fast contraction - easily fatigue - glucose store energy production
78
Benefits of warm-up
-prepares the body physically and mentally
79
benefits of cool-down
- gradually reduces HR, breathing Tate and body temperature | - reduces risk of blood pooling
80
Why is flexibility important
- reduces joint stiffness | - inflexibility are more prone to injury
81
Goal of Static Stretching
to decrease a muscles resistance to stretch in order to increase range of motion
82
Active Stretching
- unassisted | - done individually without external stimuli
83
Passive Stretching
- assisted stretching | - a partner or trainer is used as the outside stimulus in the stretching exercise
84
Proprioceptive Neuromuscular facilitation stretching (PNF)
- passive stretching with a partner 1. stretches 1 muscle 2. release 3. isometric contraction 4. passively stretch muscle again
85
Foam Rolling and (Self-myofascial Release)
- Goal: to increase range of motion | - a collective term for manual therapy techniques based on the effects of applying mechanical force to self body tissue
86
