What is exercise?
A STRUCTURED type of physical acitivity, repetitive, to improve or maintain physical fitness
What is physical fitness?
Characteristics that give a person ability to perform physical activities or ADL
What are some examples of Activities of Daily Living (ADL)?
Eating, drinking , hygiene
What is the difference between exercise and sport
exercise improves health and fitness, where sports is institutionalized and performance and competition driven
What are the 2 categories under: Components of Physical Fitness?
Health and Sport
What are the important parts of Health related: physical fitness
Cardiovascular Fitness
Muscular Strength + Endurance
Flexibility
Body Composition
What are the important parts of sport related: physical fitness
Speed
Power
Balance
Coordination
Reaction Time
Agility
What parts of: Components of Physical Fitness, is required for training ADL?
All parts of health and sports fitness, needed as age increases
Why is the cardiorespiratory system important for health related fitness?
It improves how well the heart (circulatory system) and lungs (respiratory system) circulate O2 during Physical Activity
Why is Body composition a key component of health related fitness?
It tells how much fat, muscle, bone, and other body parts a person has in their body
Why is muscle strength an important part of health related fitness?
It tells the relative strength of a person’s muscle to EXERT A FORCE
Why is muscle endurance import for health related fitness?
It tells how much PA a muscle is able to do without fatigue
Why is flexibility a key component of health related fitness?
It tells how much a person is able to move their joint/Range of motion of a joint
Why is agility an important factor in sport related fitness?
It indicated how easily/quick a person can move with accuracy and speed.
Why is coordination an important factor in sport related fitness?
How well a person is able to use their senses (hearing/sight etc.) to move their body accurate & smooth
Why is Balance an important factor in sport related fitness?
Indicates how well a person can stay steady (equilibrium) while stationary & in motion

Indicates how well/quick a person is able to do work (move with speed and strength)
Why is speed an important factor in sport related fitness?
Indicates how fast + with accuracy a person can move in a SHORT PERIOD of time
What is the Dose response relationship between exercise and rise of Coronary Heart disease
Health benefits increase as the dose of physical activity, as your more active your risk for CHD decreases
What is the health benefit of improving muscular fitness?
Increasing muscle mass improves BMR, because muscle uses more respiration.
What is infarction?
irreversible tissue death
ischemia
a lack of blood flow that causes decreased Oxygen flow
How are ischemia and infarction linked to risks in PA and CHD/CVD?
if an ischemic artery can’t get blood flow over time, causes a myocardial infarction
