PEGN 107 Lecture Notes - Lecture 5: Cardiorespiratory Fitness, Bone Density, Vo2 Max
2 components of physical fitness
skill related
health related
Fitness defined
indicates a level of cardiovascular functioning that results in optimum performance and well-being
Physical fitness defined
multidimensional concept
set of attributes that people have or achieve that relate to the ability to perform physical activity
Skill related components of physical fitness
agility
balance
coordination
speed
power
functional skills (both skill and health related)
Health related components of physical fitness
body composition
cardiorespiratory endurance
flexibility
muscle strength
muscle endurance
function skills* (both health & skill related)
T/F physical activity is a subcategory of physical exercise

Bodily movement produced by skeletal mm that requires energy expenditure over the resting energy
expenditure is known as ______________ ________________
physical activity
Physical activity is ___________, ___________ and ___________
structured
repetitive
done with a goal
5 benefits of regular physical exercise
improved cardiorespiratory function
reduced CAD risk factors
reduced risk of chronic disease
decreased mortality and morbidity
increased bone mineral density
4 postulated/possible benefits from physical exercise
decreased anxiety and depression
enhanced feeling of well-being
enhanced performance of ADLs, etc
better mental health
2 risk factors of vigorous physical exercise
life-threatening cardio event
MSK injury
2014 AHA and ACSM recommendations for adults <65
physical activity 30min mod intensity 5days/week or 20min vig. 3 days/week
resistance: 2-3days/week, 8reps x2

2014 AHA and ACSM recommendations for adults >65
physical activity: mod intensity 30min aerobic 5days/week or 20min 3days/week
resistance: 2-3days/week 10-15reps x>1
balance
plan
cardiorespiratory endurance is measured directly by _______
VO2 max
What is VO2 max?
body's maximal O2 condumption
Why is a plan important for adults over 65?
keep them honest, they have more opportunities/reasons to be sedentary
Health people 2020 goals
reduce preventable threats to health
Muscle performance =
muscle strength + muscle endurance
CR Endurance is the ability to perform large muscle, ________________ intensity exercise for _______
periods
moderate-to-high
prolonged
T/F estimated VO2 max can be done using sub maximal exercise tests
True
Strength can/cannot be defined precisely
