ENVIRONMENTAL CONDITIONS - HEAT 3

Question 1

Define Heat acclimatisation

Answer 1

Occurs when heat tolerance is improved by repeated exposure to hot environments

Question 2

How long? to acclimatise

Answer 2

• first sessions should be around 15-20 mins with low to moderate intensity
• this should increase to 45-60 mins per day while increasing the intensity for approx. 8-9 days
• 5-10 days of living and training in hot environments

Question 3

Where? to acclimatise

Answer 3

• in hotter countries
  if cannot/not able to reach the country athlete uses artificial heat sources
• Saunas
• Sweat Clothing
• Climate Chambers

Question 4

When? to acclimatise

Answer 4

• Should be done 4-6 weeks prior to the comp
• at least should be done 2x per week leading up to the comp to maintain benefits

Question 5

Major adaptations to heat acclimatisation
list all 2 subcomponents

Answer 5

1. Sweating
2. Cardiovascular

Question 6

Explain all the 4 Major adaptations to heat acclimatisation in Sweating

Answer 6

• Increased blood plasma volume
• increased sweat rate
• start sweating at a lower core temp
• sweat becomes more dilute and is more efficiently transported around the body

Question 7

Explain all the Major adaptations to heat acclimatisation in Cardiovascular all 4

Answer 7

• athletes exercise with a lower core temp and skin temp due to sweating adaptations
• athlete HR is lower
• reduces the body need to send blood to the skin so that more can be sent to the working active muscles.
• increased in blood volume for increased sweating
