Environmental Phys Flashcards
1
Q
What type of events does heat/humidity effect the most?
A
long duration/ endurance events
2
Q
Conceptual heat balance equation
A
(M-W) = (K+C+R+Esk) ± S where... M= Metabolic heat production W= Mechanical work K= Conductive heat C= Convective heat R= Radiative heat Esk= Evaporative heat (skin) S= Storage of heat
3
Q
How does humidity add to the troubles caused by heat?
A
humidity compromises convective and evaporative heat loss as sweat that drips doesn’t help reduce heat
4
Q
what adaptations occur from heat acclimation?
A
- reduced core temp and HR
- increases sweat rate and onset of sweat
- improves performance capacity
5
Q
How does heat acclimation decay? at what rate?
A
every decay day there is a 2.5% loss for HR adaptation and a 7° in core temp
6
Q
What effect does high heat have on team sports performance?
A
high heat/humidity results in reduced number and duration of high speed sprints
7
Q
list some strategies to aid performance in the heat
A
CWI pre event
ice slushy consumption
cold water face spray
menthol mouth rinse
