Energy expenditure of elite level boxers during competitive exercise

Research aim: To study energy expenditure indicators of elite level boxers during competitive exercise. Research tasks: 1. To determine aerobic energy expenditure during competitive exercise of elite level boxers. 2. To determine anaerobic lactic energy expenditure during competitive exercise of elite level boxers. 3. To determine anaerobic alactic energy expenditure during competitive exercise of elite level boxers. Research participants: Ten (10) elite level boxers, who were Lithuanian national boxing team members or candidates at the time of this research. Research methods: Review and analysis of scientific literature, determination and analysis of anthropometric data, changes in heart rate during competitive exercise and lactate levels in blood before and after a competitive exercise. Determination by indirect method and analysis of the amount of oxygen consumed before and during competitive exercise; mathematical statistics calculations and analysis. Conclusions: 1. Elite level boxers during competitive exercise produced 67,2% of all energy used during aerobic energy production phase. 2. Elite level boxers during competitive exercise produced 20,9% of all energy used during anaerobic lactic energy production phase. 3. Elite level boxers during competitive exercise produced 11,9% of all energy used during anaerobic alactic energy production phase
