AB  - ObjectivesBy  studying  this  chapter,  you  should  be  able  to  do  the  following:Describe  the  changes  in  atmospheric  pressure,  air  temperature,  and  air  density  with  increasing  altitude.Describe  how  altitude  affects  sprint  performances  and  explain  why  that  is  the  case.Explain  why  distance  running  performance  decreases  at  altitude.Draw  a  graph  to  show  the  effect  of  altitude  on  V⋅O2  max  and  list  the  reasons  for  this  response.Graphically  describe  the  effect  of  altitude  on  the  heart  rate  and  ventilation  responses  to  submaximal  work,  and  explain  why  these  changes  are  appropriate.Describe  the  process  of  adaptation  to  altitude  and  the  degree  to  which  this  adaptation  can  be  complete.Explain  why  such  variability  exists  among  athletes  in  the  decrease  in  V⋅O2  max  upon  exposure  to  altitude,  the  degree  of  improvement  in  V⋅O2  max  at  altitude,  and  the  gains  made  upon  return  to  sea  level.Describe  the  potential  problems  associated  with  training  at  high  altitude  and  how  one  might  deal  with  them.Explain  the  circumstances  that  caused  physiologists  to  reevaluate  their  conclusions  that  humans  could  not  climb  Mount  Everest  without  oxygen.Explain  the  role  that  hyperventilation  plays  in  helping  to  maintain  a  high  oxygen-hemoglobin  saturation  at  extreme  altitudes.List  and  describe  the  factors  influencing  the  risk  of  heat  injury.Provide  suggestions  for  the  fitness  participant  to  follow  to  minimize  the  likelihood  of  heat  injury.Describe  in  general  terms  the  guidelines  suggested  for  running  road  races  in  the  heat.Describe  the  three  elements  in  the  heat  stress  index,  and  explain  why  one  is  more  important  than  the  other  two.List  the  factors  influencing  hypothermia.Explain  what  the  wind  chill  index  is  relative  to  heat  loss.Explain  why  exposure  to  cold  water  is  more  dangerous  than  exposure  to  air  of  the  same  temperature.Describe  what  the  “clo”  unit  is  and  how  recommendations  for  insulation  change  when  one  does  exercise.Describe  the  role  of  subcutaneous  fat  and  heat  production  in  the  development  of  hypothermia.List  the  steps  to  follow  to  deal  with  hypothermia.Explain  how  carbon  monoxide  can  influence  performance,  and  list  the  steps  that  should  be  taken  to  reduce  the  impact  of  pollution  on  performance.
