Using data from Energy and Oxygen Consumption Rates (Power) table, calculate the daily energy needs of a person who sleeps for 7.75 h, walks for 2.00 h, attends classes for 5.75 h, cycles for 2.00 h, sits relaxed for 3.75 h, and studies for 2.75 h. (Assume the person was cycling at 15 km/h. Studying consumes energy at the same rate as sitting in class.) ### Energy and Oxygen Consumption Rates for an Average 76-kg MaleThis table provides a detailed overview of energy and oxygen consumption rates for various activities performed by an average 76-kg male. The data is measured in terms of energy consumption (in watts) and oxygen consumption (in liters of O2 per minute).| Activity | Energy Consumption (watts) | Oxygen Consumption (liters O2/min) ||---------------------------------|----------------------------|-----------------------------------|| Sleeping | 83 | 0.24 || Sitting at rest | 120 | 0.34 || Standing relaxed | 125 | 0.36 || Sitting in class | 210 | 0.60 || Walking (5 km/h) | 280 | 0.80 || Cycling (13–18 km/h) | 400 | 1.14 || Shivering | 425 | 1.21 || Playing tennis | 440 | 1.26 || Swimming breaststroke | 475 | 1.36 || Ice skating (14.5 km/h) | 545 | 1.56 || Climbing stairs (116/min) | 685 | 1.96 || Cycling (21 km/h) | 700 | 2.00 || Running cross-country | 740 | 2.12 || Playing basketball | 800 | 2.28 || Cycling, professional racer | 1855 | 5.30 || Sprinting | 2415 | 6.90 |### Explanation:- **Lower Energy Activities:** Activities such as sleeping, sitting at rest, and standing relaxed have lower energy and oxygen requirements.- **Moderate Energy Activities:** Activities like walking, cycling at a moderate pace, and playing tennis demand a moderate increase in energy and oxygen consumption.- **High Energy Activities:** High-intensity activities such as sprinting and professional cycling require significantly higher levels of energy and oxygen, reflecting the increased physical exertion.This data is essential for understanding the physiological demands of different activities and can be used for educational purposes to illustrate the relationship between physical activity and energy expenditure.

Using data from Energy and Oxygen Consumption Rates (Power) table, calculate the daily energy needs of a person who sleeps for 7.75 h, walks for 2.00 h, attends classes for 5.75 h, cycles for 2.00 h, sits relaxed for 3.75 h, and studies for 2.75 h. (Assume the person was cycling at 15 km/h. Studying consumes energy at the same rate as sitting in class.)

### Energy and Oxygen Consumption Rates for an Average 76-kg Male

This table provides a detailed overview of energy and oxygen consumption rates for various activities performed by an average 76-kg male. The data is measured in terms of energy consumption (in watts) and oxygen consumption (in liters of O2 per minute).

| Activity | Energy Consumption (watts) | Oxygen Consumption (liters O2/min) |
|---------------------------------|----------------------------|-----------------------------------|
| Sleeping | 83 | 0.24 |
| Sitting at rest | 120 | 0.34 |
| Standing relaxed | 125 | 0.36 |
| Sitting in class | 210 | 0.60 |
| Walking (5 km/h) | 280 | 0.80 |
| Cycling (13–18 km/h) | 400 | 1.14 |
| Shivering | 425 | 1.21 |
| Playing tennis | 440 | 1.26 |
| Swimming breaststroke | 475 | 1.36 |
| Ice skating (14.5 km/h) | 545 | 1.56 |
| Climbing stairs (116/min) | 685 | 1.96 |
| Cycling (21 km/h) | 700 | 2.00 |
| Running cross-country | 740 | 2.12 |
| Playing basketball | 800 | 2.28 |
| Cycling, professional racer | 1855 | 5.30 |
| Sprinting | 2415 | 6.90 |

### Explanation:

- **Lower Energy Activities:** Activities such as sleeping, sitting at rest, and standing relaxed have lower energy and oxygen requirements.
- **Moderate Energy Activities:** Activities like walking, cycling at a moderate pace, and playing tennis demand a moderate increase in energy and oxygen consumption.
- **High Energy Activities:** High-intensity activities such as sprinting and professional cycling require significantly higher levels of energy and oxygen, reflecting the increased physical exertion.

This data is essential for understanding the physiological demands of different activities and can be used for educational purposes to illustrate the relationship between physical activity and energy expenditure.

Expert Solution

Step 1

Energy consumption refers to the energy that is used for performing any particular action. One Watt is the amount of 1 Joule of energy used up in 1 second. The energy used up by any particular activity can be calculated by the product of energy consumption and the time for which activity takes place. The total energy can be calculated by the summation of all the energy used by each activity.
