Respiratory Training Flashcards

1
Q

Inefficient breathing patterns cause increases in…

A

VE, VE/VO2 (above ventilatory threshold), VE/VCO2 (above RCP), breathing frequency, dead space ventilation

Q

What is dead space ventilation?

A

Anatomic dead space: airways leading to alveoli (roughly 156+/- 28ml in males)

Q

What is the O2 cost of increased ventilation?

A

O2 cost of exercise hypernea is a significant fraction of total VO2max
When working at 70% of VO2max, about 5% of total O2 is consumed
100% = 20% consumed

Q

How can the work of breathing be measured?

A

Oesophageal balloons measure pressure in the lungs

Plot and larger the difference, higher the work of breathing (no direct measurement of O2 consumption)

Q

How is max voluntary ventilation (MVV) measured?

A

Forcefully breathing into a bag (very different to ventilation during max exercise)

Q

What did Romer et al., (2002) find in terms of respiratory muscle fatigue?

A

Analysed inspiratory mouth pressure following a 20km time-trial and athletes could not generate same pressures at 2, 10 or 30-mins post

Q

What could be the reason for Romer et al., (2002)’s findings?

A

Either competition for blood-flow between locomotor and respiratory muscles or
Elevated acid milieu

Q

What were Mador et al., (1991)’s findings?

A

Higher breathing frequency, higher total ventilation, more inefficient breathing (dead space ventilation), no change in tidal volume

Q

What is the metaboreflex?

A

a “security system” made up of sensors/receptors sample the respiratory environment which may shut down blood flow to certain areas to ensure breathing muscles get the required O2

Q

What is the lactate shuttle?

A

The movement of lactate intra- and inter- cellularly. Lactate can then be shuttled to adjacent or remote cells including the heart and active muscles

Q

What are the main changes which occur following respiratory muscle training?

A
•	Increase endurance time of muscles
•	Improvements in constant load tests
•	Post-exercise BLa decreases
•	Breathlessness decreases
Benefits in both trained and untrained individuals
