Role of Exercise Physiologist and Cardiovascular Training - Quiz

1. Question

What is the consensus-based recommendations from the Australian Clinical Guidelines for stroke management to address the loss of cardiorespiratory fitness in stroke survivors?

All stroke survivors should commence cardiorespiratory training during their inpatient stay
Stroke survivors should be encouraged to participate in ongoing regular physical activity regardless of their level of disability.
The most effective time to commence cardiorespiratory training is in the chronic stages (> 6 months) of stroke recovery
For stroke survivors, rehabilitation should include individually-tailored exercise interventions to improve cardiorespiratory fitness in the acute stages (< 1 month) of stroke recovery
Both A and B

2. Question

Using the components of the FIIT principle, what is the quantity (frequency and time) needed to improve cardio-respiratory fitness (VO2max) following a stroke if intensity is regularly maintained at 55-75% MHR each session

Frequency one day per week for up to 6 months; 30 mins per session
Frequency 5 days per week for 2 weeks; 10 mins per session
Frequency 3-5 days per week for up to 8-12 weeks; 20-60 mins per session
Frequency 2 days per week for 6 weeks; 30 mins per session
Frequency 1-2 days per week for up to 4-6 weeks

3. Question

How would you introduce a stroke client to participate in a cardiorespiratory training program for the first time in the first 2 weeks?

Moderate intensity exercise 64-75% MHR or breathing more heavily but can still speak brief sentences; greater than self-selected pace which is outside their comfort zone. Resistance must stay low to minimize neuromuscular fatigue
High intensity exercise 77-93% MHR or breathing is becoming more difficult and only able to say a few words at a time; implementing bursts of sprint interval training (SIT) at “all out” effort
Light intensity exercise <64% MHR or able to hold a conversation comfortably; self-selected pace initially to build exercise tolerance to increase motivation and adherence to an exercise session
Combination of moderate to high intensity exercise. Resistance must be high to promote neuromuscular fatigue and maximise aerobic training adaptations.
Combination of light intensity to high intensity exercise. Encourage to sustain high levels of aerobic exercise for as long as possible before rest periods.

4. Question

Brain Derived Neurotrophic Factor (BDNF) are small proteins or “growth” factors in the brain that acts on certain neurons of the central nervous system and peripheral nervous system. What is the role of BDNF and aerobic exercise

BDNF is released after an intense bout of aerobic exercise of approx. 70% MHR firing regions of the brain that are responsible for movement and facilitate motor re-learning rehab
BDNF is released only in the acute stages of stroke recovery following an intense bout of aerobic exercise of approx. 70% MHR which is essential for motor re-learning rehab
BDNF is released following task specific training and gait retraining prior to aerobic exercise training
BDNF is released for approx. 10-60 mins and returns to baseline following a bout of low intensity aerobic exercise
BDNF is released only in the chronic stages of stroke recovery following an intense bout of aerobic exercise of approx. 70% MHR which is essential for task specific training and gait retraining
