GRADES 8 - 12
MONITORING ENERGY EXPENDITURE

OBJECTIVES: This is the second of three life science lessons that were used as part of the SSET (Sport Science, Engineering and Technology) Program hosted at MIT and sponsored by John Hancock Financial Services, the New Balance Foundation, CDM, Phi Alpha Foundation, The New England Women's Fund and The Society of Women Engineers. The first and third lessons are Energy Balance: The Ins and Outs and Training for Three: Triathlon. This section is designed to give the students insight into the methods used to determine the energy cost of activities. Both direct and indirect methods will be discussed with the primary focus on the indirect methods. Students can use heart rate monitors (or take their pulse) and complete a swimming and running test. These tests or labs are designed to obtain personal data, manipulate the data through calculations of various parameters (i.e. oxygen consumption and caloric expenditure), and graphically represent the data. Students will use these datasets to discuss the concepts profiled in the "Energy Balance: The Ins and Outs" and the "Monitoring Energy Expenditure" lectures. They will also use the information in the final lesson to discuss how they could train for a triathlon (Training for Three: Triathlon).
