explain oxygen deficit and oxygen debt. how is it possible for the human body to instantaneously provide the energy needed when changing from rest to exercise ?How are oxygen deficit and oxygen debt affected by exercise intensity and duration ? what factors can affect EPOC and what role do these factors play during recovery ?

Solution

oxygen deficit:while exercising intenesely the body is unable to fulfill all of its energy needs, especially oxygen it is unable to absorb enough oxygen.to adequately feed the muscles the amount of energy needed to adequately perform the task the athlete is requesting from the body.in order to make up the difference without sacrifying the output. the body must tap in to anaerobic metabolism.this where the body goes mix up with a aerobic and anaerobic production.(or)oxygen deficits can grow a level that the anaerobic energy cannot cover, this can cause to deteriorate...

oxygen debt:it is defined as the volume of the oxygen used during recovery from exercise in excess of resting oxygen consumption, occurs after anaerobic exercise.

one of the most possible change occur to produce energy continiously Atp are used to produce energy . the changes induced by exercise take place in the cardiovascular system. Within the first few seconds after exercise begins, there is a tremendous amount of increased demands placed on the body. To maintain homeostasis, these demands have to be matched by significant alterations in the cardiovascular system. To prolong exercise, contracting muscles require an efficient delivery system as they require vast amounts of nutrients and oxygen, while producing waste and heat that need to be discarded.

epoc is a measurably increased rate of oxygen intake following strenuous activity intended to erase the body\'s \"oxygen deficit\". In recovery, oxygen (EPOC) is used in the processes that restore the body to a resting state and adapt it to the exercise just performed. Post-exercise oxygen consumption replenishes the phosphagen system. New ATP is synthesized and some of this ATP donates phosphate groups to creatine until ATP and creatine levels are back to resting state levels again..

epoc factors:( excess post exercise oxygen consumption):crp replishment,metabolism lactate,temperaturerecovery, hr recovery ,ventilation recovery,hamones recovery.

factors affect epoc:

Program design and the manipulation of variables such as intensity and duration can have a significant effect on the outcome of a training program. Aerobic exercise intensity has long been known to have an effect on EPOC . EPOC value, which are measured in L/min of oxygen consumption or Kcal/min, have been seen to more than double when increasing intensity from 55 to 95% of VO2 max for two-minute intervals . Even when controlled for total energy expenditure during the exercise session, increasing exercise intensity from 50 to 75% VO2 max results in an almost doubling of EPOC . While exercise intensity is the most important contributor to EPOC, accounting for of the systematic variance in EPOC at exercise intensities above 50% of VO2 max, there is a linear relationship between the duration of EPOC and the duration of the exercise session . This relationship holds true for both submaximal and supramaximal exercise are the important factors play a role in recovery process.
