TRAINING FOR THREE: TRIATHLON

OBJECTIVES: This is the third 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 two lessons are Energy Balance: The Ins and Outs and Monitoring Energy Expenditure. The final lecture is entitled, "Training for Three: Triathlon". The focus of this section is on : basic metabolism; . the role of endurance training in triathlon performance; . and the concept of training in three different events. The students will complete a final exercise test (cycle ergometer) that will enable them to discuss their potential in each of the three events. Students are introduced to the concepts of economy and efficiency in running, swimming and cycling. They will use their own dataset to make decisions as to their abilities in each sport domain.
