Endurance Diet Part I. A representative meal at the beginning of the expedition (Dec. 1914)
Analysis: a. Total Calories consumed in this meal: b. Estimate the calories consumer per day by multiplying the meal Calories by 3: c. At this point of the expedition, the activity level of the men per day is estimated at between 4,000 and 6,000 Calories. Did the men consume enough food or did they expend more calories then they consumed? Part II. A representative meal at the middle of the expedition when locked on ice floes (Dec. 1915):
Analysis: a. Total Calories consumed in this meal: b. Estimate the calories consumer per day by multiplying the meal Calories by 3: c. At this point of the expedition the activity level of the men per day is estimated at between 6,000 and 8,000 Calories. Did the men consume enough food or did they expend more calories then they consumed? Part III. A representative meal at the end of the expedition (May 1916):
Analysis: a. Total Calories consumed in this meal: b. Estimate the calories consumer per day by multiplying the meal Calories by 3: c. At this point of the expedition, the activity level of the men per day is estimated at between 7,000 and 10,000 Calories. Did the men consume enough food or did they expend more calories then they consumed? Part IV: Make a chart so that you can record what you eat in one day. You should have a section for breakfast, lunch, dinner, and snacks. Analyze your food consumption for that day in the same manner that you did the explorers'. You need a calorie reference in order to do this. The number of calories you expended in that day mainly depends on your activity level, height, weight, body build, and gender. An average-sized female consumes 1,900 calories if inactive, 2,200 calories with moderate activity and 2,400 calories if active. An average-sized male correspondingly consumes 2,200, 2,500, and 2,800 calories. Consider the accuracy of your work. What assumptions and/or estimates did you make? Part V: Bar Graph Analysis This is an analysis of Kilocalories consumed versus Kilocalories expended by the explorers and you. Key: Blue pen bar represents calories consumed Red pen bar represents calories expended  NOVA's Expeditions (1999 & 2000) | Shackleton's Expedition (1914) Surviving Antarctica | Navigating the High Seas | Dispatches Mail | Resources | Classroom Resources | Site Map | Shackleton Home Editor's Picks | Previous Sites | Join Us/E-mail | TV/Web Schedule | About NOVA Watch NOVAs online | Teachers | Site Map | Shop | Search | To Print PBS Online | NOVA Online | WGBH © | Updated February 2002 |
