Name the four types of basic thermoregulation
•Radiation – transfer of heat without contact
•Ex = sun, heat lamps, fire
•Conduction – transfer of heat with surface contact
•Ex: hand warmers, hot/cold metal
•Convection – transfer of heat to air or water molecules
•Ex: fans, wind
•Evaporation – heat transfer via water evaporation to gas form (removing heat)
•Ex: lovely dripping sweat (but the drips don’t count)

What is considered 3-component model when assessing body comp?
How can a beta-blocker be used as an ergogenic aid?
•Mechanism
•Block catecholamine action at β-receptors
•↓HR, ↓Cardiac output
•Dilation of smooth muscle
•Proposed benefit
•↓anxiety & tremor
•↓HR at rest ~7-10bpm
•Effects
•Improved shooting scores
•↓O2 uptake, blood flow, HR, BP, CO
•Risks
•Bronchospasm (asthmatics)
•Dizziness, fatigue
Hypoglycemia
