What are 5 factors affecting body temperature ✔✔CORRECT
ANSWERS✔✔1) Metabolic Heat Production
2) Conductive Heat Exchange
3) Convective Heat Exchange
4) Radiant Heat Exchange
5) Evaporative Heat Loss
Normal metabolic function in the body results in the production and
radiation of heat; the higher the metabolic rate, the more heat
produced is called what? ✔✔CORRECT ANSWERS✔✔Metabolic Heat
Production
Physical contact with other objects can result in either heat loss or heat
gain is called what? ✔✔CORRECT ANSWERS✔✔Conductive Heat
Exchange
Body heat can be either lost or gained, depending on the temperature
of the circulating medium is called what? ✔✔CORRECT
ANSWERS✔✔Convective Heat Exchange
,Radiant heat from sunshine causes an increase in body temperature
and
the body attempts to dissipate heat produced by metabolism by dilating
superficial arterial and venous vessels is called what? ✔✔CORRECT
ANSWERS✔✔Radiant Heat Exchange
Sweat glands in the skin allow water to be transported to the surface
where it evaporates, taking large quantities of heat with it, is called
what? ✔✔CORRECT ANSWERS✔✔Evaporative Heat Loss
- A normal person can sweat off about 1 quart of water per hour.
Evaporation is severely impaired when the relative humidity reaches
65% and virtually stops at 75%
- Sweating does not cause heat loss, the sweat must evaporate for heat
to be dissipated, and the air must be relatively free of water for
evaporation to occur
Hydration is important to ingest sufficient fluids throughout the
_______ hour period preceding exercise ✔✔CORRECT ANSWERS✔✔24
hours
In order to be hydrated, what should the colour of urine output be?
✔✔CORRECT ANSWERS✔✔urine should ideally appear light yellow -
the colour of lemonade
- completely clear means over-hydration
,- dark urine means dehydration (colour of cider)
How much fluid should you drink prior to exercise
a) 1-5 oz
b) 5-10 oz
c) 17-20 oz
d) 20-30 oz ✔✔CORRECT ANSWERS✔✔c) 17-20 ounces or 2-3 sport
drinks 10-20mins before exercise
What are some physiological effects of hypohydration ✔✔CORRECT
ANSWERS✔✔reduced muscle strength and endurance, decreased blood
and plasma volume, altered cardiac function, impaired
thermoregulation, decreased kidney function, reduced glycogen stores
and loss of electrolytes
How many days should gradual acclimatization progressive exposure
occur?
a) 2-4 day
b) 5-8 day
c) 7-10 day
d) 9-15 day ✔✔CORRECT ANSWERS✔✔c) 7-10 day period, and during
first 5-6 days and 80% acclimatization can be achieved on basis of 2
hour practice period in the afternoon
, True or False. Males are more physiologically efficient in body
temperature regulation than women. ✔✔CORRECT ANSWERS✔✔False.
Women are more efficient. Women tend to sweat less and manifest a
higher HR when working in heat
What index provides an objective measure for determining precautions
for practice and competition in hot weather ✔✔CORRECT
ANSWERS✔✔WBGT: Wet bulb globe temperature
- Incorporates the readings from 3 different thermometers (Dry bulb,
wet bulb and globe temperature)
What is the WBGT calculation? ✔✔CORRECT ANSWERS✔✔WBGT = 0.1
X DBT + 0.7 X WBT + GT X 0.2
Fun Facts: Heat Rash ✔✔CORRECT ANSWERS✔✔- Benign condition
associated with a red raised rash accompanied by sensations of
prickling and tingling during sweating
- Localized to areas covered with wet clothing
Fun Facts: Heat Syncope ✔✔CORRECT ANSWERS✔✔Heat collapse
associated with rapid physical fatigue, caused by peripheral vasodilation
of superficial vessels, hypotension or a pooling of blood in the
extremities
