Document Summary

Soccer is only 10% aerobic; usually 80% walking/jogging around; so most of the time they are recovering from the short duration of high intensity movements; need to be aerobically fit. However, the average hr is high (170) Cofactors and coenzymes with pyruvate dehydrogenase (tpp) thiamine pyrophosphate. Adenine dinucleotide (coa) coenzyme a (mg2+) metal ion. Power perspective: phosphocreatine system will be active for a short duration (atp being broken down). This system is used when there a maximum effort given for a short duration that is very explosive. After reaching 10 seconds, phosphocreatine system will be depleted; as we use pcr to maintain the energy levels, that"s when the glycolytic pathway happens (breaking down carbohydrates to give energy; and eventually that becomes depleted) Atp is the high energy compound used to fuel exercise. Cells contain a storage form of high energy known as phosphocreatine (pcr) or creatine phosphate (cp)
