Achievement Task

It doesn’t get any more real or personal than this! In this achievement task you will be asked to gather information about yourself, specifically your diet and exercise habits. After gathering this information and learning about how diet and exercise can affect the Digestive, Circulatory, and Respiratory Systems, you will analyze your data. Hopefully, this will enable you to make better informed decisions in the future regarding your diet and exercise habits.

1. Body Mass Index (BMI) is often used by doctor’s to determine if a person is considered underweight, overweight, or normal. This method is not without its flaws but it generally is a good indicator. Find your weight (in pounds) and height (in inches) then calculate and record your BMI after visiting this website
2. Using your BMI number, were you considered underweight, normal, overweight or obese? Do you feel this is a relatively accurate description for you?
3. Make a list of all the food you have ingested over the last 24 h. period. Include all snacks and refreshments consumed.
4. Calculate the caloric intake (Energy Input) of this food you have ingested over the last 24 h. period using this website
5. Calculate and record your Energy Output over the last 24 h period using the formula provided at the following website
6. In this unit you have studied three important body systems. How can your diet positively impact on the
   1.  respiratory system
   2. cardiovascular system
   3. digestive system
7. Training the respiratory system involves a long term (hopefully lifetime) commitment to aerobic exercise. Even though the benefits of this type of program go far beyond the respiratory system, list the training adaptations the respiratory system itself receives from aerobic exercise.
8. The circulatory system also can undergo dramatic changes with an exercise training program. List the training adaptations for this system

1. Do you feel that the BMI is a useful indicator in determining whether a person is underweight, normal, overweight, or obese?
2. Analyze your diet, looking not only at what you have eaten over the past 24 h. but at your diet in general. Compare your diet to what is suggested in Canada’s Food Guide
3. Using the healthy diet scorecard found in this website find out which food group(s) serving suggestions you are you exceeding, meeting, and underachieving in.
4. Review the results from your caloric intake (Energy Input) over the 24 h period and compare this to your Energy Output during that same 24 h period. Did you expend more energy than you took in or did you take in more than you expended? Assuming no factors change in your diet or energy expenditure (unlikely), how long will it take you to lose or gain a pound of fat (3500 kcalories).
5. Which type of exercise can make the greatest change in your overall health (beneficially affecting the most body systems), aerobic exercise (ex. jogging, soccer) or anaerobic exercise (weight training, football). Explain.

Part C: Extension

1. Using your knowledge of all three body systems from this unit (Digestive, Respiratory, and Circulatory) and the formula for cellular respiration
2. Explain in detail how the starch from the piece of bread a runner has eaten earlier can be used for energy to make their quadricep muscle move their leg during a running stride.
