Define Heat acclimatisation
Occurs when heat tolerance is improved by repeated exposure to hot environments
How long? to acclimatise
• 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
Where? to acclimatise
• in hotter countries if cannot/not able to reach the country athlete uses artificial heat sources • Saunas • Sweat Clothing • Climate Chambers
When? to acclimatise
• 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
Major adaptations to heat acclimatisation list all 2 subcomponents
• Sweating • Cardiovascular
Explain all the 4 Major adaptations to heat acclimatisation in Sweating
• 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
Explain all the Major adaptations to heat acclimatisation in Cardiovascular all 4
• 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
