### Introduction

Runners often add elements to their training routine that create increased resistance to help build strength and speed. Running parachutes work to create drag on a runner in the same way that parachutes on race cars do. The runner must work harder to overcome the drag, leading to a greater load on the muscles as they exercise.

In this activity, you will analyze the horizontal motion of a person running as drag is increased. Using the Vernier Video Analysis app, you will compare features of the positionÂ vs. time and velocityÂ vs. time graphs as drag is increased on the runner.

### Objectives

In this experiment, you will

• Use video analysis techniques to obtain position, velocity, and time data for a person sprinting with and without running parachutes.
• Analyze the positionÂ vs. time and velocityÂ vs. time graphs for the runner as they sprint with increasing amounts of drag.
• Use video analysis techniques to obtain position of the foot data for a runner as they sprint with increasing amounts of drag.
• Determine step rate, cadence, and stride length for a person sprinting with increasing amounts of drag.
• [Extensions] Create and analyze your own video of a person sprinting with increasing drag.
