balancing benefits and risks: common risks

Answer 1

1. sudden cardiac arrest

3. injuries
4. airways

Question 2

sudden cardiac arrest

Answer 2

very rare- difficult to study
risk is 5 to 56 times greater during vigerous exercise than during usual activities of daily living
2-4 times more common young athletes compared to non-athletes
risk is highest if you do not normally exercise

Question 3

sudden cardiac arrest causes

Answer 3

1) loss of electrical stability

2) myocardical infarction (plaque)

Question 4

why? cardiac arrest

Answer 4

1. exercise increases heart rate
2. may rupture piece of plaque
3. heart muscle requires more O2 than it can receive
4. electrical instability

Question 5

when cardiac arrest

during vigerous exercise

especially if you stop suddenly

Question 6

who cardiac arrest

Answer 6

35 year old - coronary artery disease

Question 7

what can we do cardiac arrest

Answer 7

short term vs long term benefits/ risks

moderate intensity leads to health benefits

screening with EGG

cool down

training intensity and volume

Question 13

osteoporosis leads to

Answer 13

disruption in estrogen

Question 14

why does female triad matter

Answer 14

• physiological health
• fertility
• bone health- risk for fracture

Question 15

what can we do about female triad

Answer 15

• early indentification
• education
• rest periods

6. properly fitting equipment

Question 18

why? injuries

Answer 18

1. keep athletes safe
2. sustain fun
3. sustain PA

Question 19

concussion

Answer 19

• hot research topic
• can have life long consequences
• long lasting symptoms

Question 20

clip on concussion

Answer 20

• rates of confussion in female athletes higher
• athletes down play concussions
• concern: one can lead to risk to get 2nd or repeat

Question 21

airways who?

Answer 21

5-10% prevalance vs

10-50% in elite endurance athletes

Question 22

air ways why?

Answer 22

moderate exercise vs 
repeated high intensity exercise 
increased exposure to allergens/pollutants 
immune system
cold air or water

Question 23

what to consider

Answer 23

who- previous PA, previous health conditions
what- intensity/ duration
where- temp

Question 24

key points

Answer 24

exercise beneficial but can cause injuries
balance risk and benefit
moderate PA is best for decrease risk/ increased PA
long term consequences of intense PA
risk of sudden cardiac arrest is a sedentary pop who engaging in vigorous PA
