The impact of critical power in the Oxygen deficit and EPOC and the variables related to the Oxygen and CO2 for handball Players

Abstract

The current study aims to know the amount of Oxygen deficit and the variables related to Oxygen at the testing of critical power (3 min out-all). We achieved the objectives of this research by testing 10 football players team in Al-Qadisiya university and the means of their length (177 m), weight (70 kg) and the age (20.3 year). In addition, we utilize a promising technique (K5) to measure the Oxygen deficit and the variables related to Oxygen, and deploying K5 to extract different variables such as (pulmonary ventilation, respiratory parameters, VO2MAX, heart rate, oxygen ventilation equivalent, ventilation equivalent of carbon dioxide, oxygen deficit, oxygen EPOC). Where testing the critical power on the Bicycle physical effort (model Monarch) be selecting level (mini out – all 3) for 3 minutes. As a procedure of experiment the players have to exercise in a maximum speed of cycling against the resistance represented 4.5% of the weight of player body. During that, the player should keep the producing power in steady sate and consider the average of producing power for the last 30s as a critical power. As a result, the experiment show that there is a relation between the critical power and the Oxygen deficit with EPOC and we notes that there is no relation appear with the critical power and  Oxygen deficit and EPOC
