• Attending the visitation
Post-race Review
What went right?
–Most everything
What went wrong?
–Identify
Proposed changes
–Make it better
New Medical Developments
Collapsed athlete differential
diagnosis
Cardiac arrest
Exertional heat stroke
Hyponatremia
–May present with muscle cramping
–May be asymptomatic for several hours
Moderate to severe EAC
–Diagnosis of exclusion
–Resolves with support & time
–Leg elevation
Defibrillators
Types available
–Automatic defibrillators (AED)
–Manual defibrillators
Locations
–On site
–On course
AED’s on bikes expand range of care
Hyponatremia
Marathon & longer races
3 deaths past 18 months
–2 confirmed; 1 suspected
–Water excess & dilution
Increased in "hot" conditions
Significance
–Can be fatal
–Often associated with seizure
Hyponatremia & Fluid
Recommendations
Causes
–Too much fluid intake
–Excess salt losses
Water or hypotonic replacement
Problem in longer races (>4 hrs)
–Unlikely in shorter distance races
–Female athletes 9:1
Parallels rise in charity running & slower
average times
More common in Ironman Triathlons
Key history
Finish time > 4 1/2 hours
–Slow pace
–Long duration activity with lower intensity
High fluid intake
–Mostly water
–"2 full glasses at every water stop"
Not 2 "swallows"
Hot & humid conditions
Key history
Not acclimatized to current temp & RH
Weight changes
–Expect drop in weight
Glycogen utilization & depletion
Mild dehydration for "normal" finisher
–Key weight is training weight
Not pre-race weight
Pre-race weight includes
Glycogen loading & associated water
Symptoms /Signs
Early
–Lightheaded
–Dizzy
–Nausea
–Headache
Severe
Progressive
Middle
–Vomiting
–"Puffy"
–Muscle cramps
–BP, HR, RR normal
–"Impending doom"
–Dyspnea
–Confusion
Late
–Ashen, gray
appearance
–Prolonged seizure
–Obtundation
Hyponatremia Solutions
Education runners
–Replace sweat losses
–Forget "drink as much as you can"
Decrease water stops to every 3 K
–Break down extra large field stops at 4
hour plus pace
"Myth" information
–Sports drinks do not prevent
Educate volunteers
Measure Na+ on site
Prevention
Dehydration during marathon races occurs
–Rarely "severe"
–More common than exertional
hyponatremia
–Life threatening rate similar to exertional
hyponatremia?
Slow competitors
–Limit fluid intake & add salt to fluids
Salty sweaters use salted fluids & salt food
Pre-race, race, & post -race
hydration recommendations
Current ACSM recommendation
–"Replace what you need"
–Replace sweat losses
Race practice has been "One size fits all"
–6-12 oz each competitor every 15-20 min
–Ignores individual differences
Sweat rate
Acclimatization
Intensity of exercise
Individualized Fluid Intake
Calculate fluid needs
–For anticipated race pace & conditions
Pre- & post-run weights
–Nude body weight
–½ hour run
Race pace
Anticipated race conditions
–Towel off & re-weigh nude
–Fluid required / hr = weight difference
(oz) x 2
Race Specific Recommendations
By distance
–< 20 K think of heat stoke
–20-50 K think of exhaustion & exercise
associated collapse
–> 50 K think of hyponatremia
–All think cardiac arrest
By size
–Very large races fluid stations
–Risk of too much fluid intake
Race Specific Recommendations
By environment
–Hot, humid
–Hot
–Cool
–High altitude
Summary
Audit your race
Emergency care
What if...?
–Its too hot
–Its too cold
–Someone dies
–A car crashes the course
Think runner safety
