Question

Please answer question 16 and provide all work needed.

The image contains a list of exercise-related questions involving calculations of energy expenditure, METs (Metabolic Equivalents), and other variables related to workouts on machines like treadmills and ergometers. There are no graphs or diagrams in the image. Here is the transcription of the text: --- c. 700 kg m/min on a Monarch ergometer 15. What stepping rate is needed if a person wants to work at a Vo2 of 40 mL/kg/min using a bench that is 40 cm high? 16. A 170 pound man wants to design a workout (on a treadmill) that will expend 300 kcal. He wants to walk 45 min. at a speed of 3.5 mph. What elevation does he need to set the treadmill to complete this workout? 17. How many METs does a 155 pound woman expend when running at 6.5 mph and a 2.5% grade? 18. How long would a 185 pound man have to walk at 3.5 mph and a 5% grade to expend 400 kcal? 19. How many Watts does one produce when the resistance is set at 2.0 kg and the pedal rate is 70 rpm on a Monarch bicycle ergometer? 20. How many kcal does a 155 pound man expend when he rides a Monarch bicycle ergometer at 150 Watts for 20 min.? 21. If a 65 kg person pedals a Monarch leg ergometer at 60 rpm, how much resistance is needed to work at a level of 10 METS? 22. How many kcal would a 160 pound man expend when he steps up a 10 inch bench at a rate of 18 steps/min for 20 min.? --- These questions can be used for educational purposes to teach about exercise physiology and calculating energy expenditure in physical activities.
