Aerobic Health Flashcards
What is the relationship of MVPA to the relative risk of death?
AS MVPA increases from 60 to 420 minutes per week, the relative risk of early death will decrease from 1.0 to 0.6
How many minutes of MVPA is needed to show substantially lower risk?
About 150 minutes per week for adults
If a person is PA for 7 hours of the week, how much does that lower their risk of premature death and compared to who?
30-40% - compared to someone who does less than 30 minutes per week
Is the relationship between premature death and MVPA a dose-response?
Yes - amount of PA and a risk of poor health
If you have a strong cardiorespiratory system, what are you good at?
Aerobic exercise
What is the single most important component of health related fitness?
Aerobic exercise
What is aerobic exercise good for in terms of diseases?
Preventing CVD
How much aerobic exercise do you need to prevent CVD?
About 30-60 minutes of moderate intensity exercises on 3 to 5 days of the week
How important is PA in our lives?
It is very important but it is no longer a part of our existence
What is a hypo kinetic disease?
A chronic condition related to a lack of PA
What is cardio respiratory?
Pertains to the cardiac and respiratory systems
What is aerobic exercise?
Producing energy for PA with oxygen
What is anaerobic exercise?
Producing energy for PA without oxygen
What is adenosine triphosphate (ATP)?
Chemical compound that is the immediate source of energy for PA
What cycle is involved in ATP?
Krebs cycle
What does ATP do to the body?
Conducts movement through energy
What is a lactate threshold?
When there is an increase in lactic acid accumulation, and thus a better recruitment of fast twitch muscle fibers (for anaerobic activities)
Is the lactate threshold the same thing as the anaerobic threshold?
Yes - it transitions from using oxygen to having too much lactate to produce oxygen anymore and then it recruits fast twitch (type II) fibers
What is the aerobic capacity known as?
VO2 max
What happens when you work above the aerobic capacity?
You hit the aerobic maximum and work into the lactate/anaerobic threshold where oxygen is no longer used to produce your energy
What physiologically things occur when you work above your aerobic capacity?
- Lactate blood accumulates
2. Breathing increases
What happens to your VO2 max when you train?
It can improve from 50% VO2max to 75%
What is aerobic exercise?
Exercise using a steady supply of oxygen to contract and function
Who, when, and how was the term aerobic coined?
Dr. Kenneth Cooper in 1968 because of his book called “Aerobics”
