Chapter 16 Flashcards
balancing benefits and risks: common risks
- sudden cardiac arrest
- female cardiac arrest
- injuries
- airways
sudden cardiac arrest
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
sudden cardiac arrest causes
1) loss of electrical stability
2) myocardical infarction (plaque)
why? cardiac arrest
- exercise increases heart rate
- may rupture piece of plaque
- heart muscle requires more O2 than it can receive
- electrical instability
when cardiac arrest
during vigerous exercise
especially if you stop suddenly
who cardiac arrest
35 year old - coronary artery disease
what can we do cardiac arrest
short term vs long term benefits/ risks
moderate intensity leads to health benefits
underlying problem cardiac arrest
screening with EGG
cool down
female triad
ammenorrhea
I
female triad
/ \
osteoprosis disordered eating
who? female triad
long distance athletes
gynasts
dancers
prevalence of all three is how many times greater
5-10 time greater in elite female athletes
ammmenorrhea may be related more to what
training intensity and volume
osteoporosis leads to
disruption in estrogen
why does female triad matter
- physiological health
- fertility
- bone health- risk for fracture
what can we do about female triad
- early indentification
- education
- rest periods
injuries
muscoloskeletal
concussion
what can we do about injuries
- avoid over training
- proper warm up
- attempts to train sensory-motor responses
- rules/ regulations
- coaching
- properly fitting equipment
why? injuries
- keep athletes safe
- sustain fun
- sustain PA
concussion
- hot research topic
- can have life long consequences
- long lasting symptoms
clip on concussion
- rates of confussion in female athletes higher
- athletes down play concussions
- concern: one can lead to risk to get 2nd or repeat
airways who?
5-10% prevalance vs
10-50% in elite endurance athletes
air ways why?
moderate exercise vs repeated high intensity exercise increased exposure to allergens/pollutants immune system cold air or water
what to consider
who- previous PA, previous health conditions
what- intensity/ duration
where- temp
key points
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
