Acute Responses + Respiratory System Flashcards
What is an Acute Response?
Acute responses are immediate responses at the onset of exercise anytime intensity increases
Which 3 body systems are talked about in terms of Acute Response?
Respiratory System, Cardiovascular System and Muscular System
What does an Acute Response allow an athelet to do
Work at a higher intensity aerobically
What does the Respiratory System refer to?
Lungs
What are lungs shaped like and why?
Upside down broccolli to increase surface area
What are the tiny sacs found at the end of lungs called
Alveoli
What wraps around the Alveoli?
Capillaries (Blood vessels)
They share a wall to allow diffusion to occur
What is diffusion?
Movement of gasses from area of high concentration to area of low concentration
What is Respiratory Rate?
Number of breaths per minute
What is Tidal Volume?
Amount of air inspired and expired per breath
What is Ventilation?
The amount of air inspired and expired per minute
How is Ventilationn calculated?
Respiratory Rate x Tidal Volume = Ventilation
What does an increase in ventilation result in?
Increased ventilation leads to more oxygen being brought into body to be made availabe to the working muscles so they can work at a higher intensity aerobically
Give example rates of RR, TV and V at Rest, Moderate and Maximal Intensity
- Rest - RR(12) - TV(0.5) - V(6)
- Moderate - RR(30) - TV(2.5) - V(75)
- Maximal - RR(48) - TV(4) - V(192)
Ventilation Rate is most important to note
What type of breathing is beneficial during high intensity work?
Combination of deep and fast breaths is most natural and efficient
What will happen to Tidal Volume at submaximal intensity?
Tidal Volume will plateau at sub-maximal intensity as Lungs cannot expand to accept anymore air. Any further increase in Ventilation will be caused by increase in Respiratory Rate.
What is Pulmonary Diffusion?
Oxygen moving from lungs (alveoli) to the bloodstream (capillaries) and Carbon dioxide moving from the bloodstream (capillaries) to the lungs (alveoli) to be expelled from the body.
