Applied anatomy and physiology - recovery, altitude, heat Flashcards
Define EPOC
Volume of oxygen consumed post exercise to return the body to a pre exercise state
Define oxygen deficit
Volume of oxygen that would be required to complete an activity aerobically
What are the 2 stages of EPOC
Fast alactacid component of recovery - oxygen consumed within 3 mins resaturates haemoglobin and myoglobin stores and provides the energy for ATP and PC resynthesis
Slow alactacid component of recovery - Shows the oxygen required to return the body to a pre exercise stage by provision of energy to maintain ventilation, circulation, body temperature and removal of lactic acid
Define gluconeogenisis
Formation of glucose form substrates such as pyruvic acid
Define altitude
Height of an area above sea level
Define humidity
Amount of water vapour in the atmospheric air
Define barometric pressure
The pressure exerted by the earths atmosphere
Define partial pressure
The pressure exerted by an individual gas held in a mixture of gases
Define diffusion
The movement of a gas across a membrane down a pressure gradient from an area of high to low pressure
What are the affects of high altitude on the cardiovascular and respiratory system
Decreased oxygen transportation to the muscle tissue and supply for energy production
Increased rate of breathing
Decreased stroke volume, blood volume and heart rate
Decreased VO2 max, aerobic capacity and endurance
Define acclimatisation
A process of gradual adaptation to change in environment
What are the benefits of acclimatisation for the cardiovascular and respiratory systems
Release of erythropoietinn increases, therefore red blood cell production increases
Breathing and ventilation stabilise
stroke volume and cardiac output reduce
