Lecture 10 - Pre-Exercise Screening Flashcards
Is it safe to exercise?
As a general rule, it is safer to exercise than to remain sedentary. Despite the overall safety of exercise, there are inherent risks, especially for individuals with certain medical conditions.
What is the percentage of incidences of cardiac arrest during rehabilitation?
relatively low, at 1 per 111,996 patient-hours
cardiac arrest is a low risk factor during exercise. What are the 2 populations it would it affect and for what reasons?
a) Over 35, usually due to CAD (M > F). Under 35, 2/3 due to structual abnormalities and 1/3 due to electrical abnormalities - frequently genetic conditions
When in relation to exericse would sudden death occur. Is it symptomatic?
~ 70% of sudden deaths occur during or shortly after
exercise
• Usually asymptomatic
– Any symptoms (e.g. fainting) or family history should be
investigated
What would be the 3 main causes of sudden death in young athetes with relation to exericse?
hypertrophic cardiomyopathy, cormotio cordis (chest blow), left ventricular hypertrophy
Does exercise increase or decrease risk factors for heart disease? What are some considerations of exercise and heart disease?
Usually exercise doesn’t cause heart disease. It decreases the risk. However it can cause problems, including death, in those with existing heart disease
What should we determine prior to exercise in an individual?
- health-status
- risk-status
- safety/intensity of exercise
What is the best environmental strategy to decrease risk of sudden death during exercise
Defribrillators. Defibrillators increasingly being credited with saving the lives of
children who have sudden cardiac arrest
What are the 4 things we are trying to identify in people in order to minimise adverse effects during exercise?
Individuals with: a) risk factors, b) conditions requiring medical supervision during exercise, c) contraindications to exercise, d) additional needs for testing and exercising (e.g.: pregnancy)
What are the stages of the ESSA pre-exercise screening tool and what do they do?
Used to classify people into three risk categories
• Stage 1 – compulsory
– Aims to determine who is at high risk
• Stages 2 – recommended, risk factor assessment
What are some things that should be assessed before exercise on a pre-exercise screening tool
– Personal history of diseases and illnesses
– Family history of disease
– Surgical history
– Past and present health behaviours (smoking, physical activity)
– Current use of drugs/medications
– History of signs or symptoms of C-P disease
What does the ESSA pre-exercise screening tool aim to understand from the individual?
a) Does the client have known medical conditions that should be
checked out, b) Any signs or symptoms of disease, c) Any other conditions that require supervision, d) How physically active is the individual
If the individual answered YES to any of the 6 questions in stage 1 of the pre-screening tool, what do they need to do?
Medical clearance is
recommended before beginning
any new exercise program OR
undertaking any aerobic fitness
testing
If the individual answered NO to all of the 6 questions in stage 1 of the pre-screening tool, what do they need to do?
Move to Q7 and determine their current intensity level.
If total PA ≤150 min/week = may begin
a low-moderate intensity physical
activity program.
If total PA ≥150 min/week = continue
exercising at current intensity
What are some signs and symptoms of CP disease?
• Pain in chest or surrounds
• Shortness of breath
• Dizziness or syncope
• Dyspnea especially at night
• Ankle oedema
• Palpitations or tachycardia
• Claudication with exercise
• Heart murmur
• Undue fatigue
