Muscle Fatigue

Lab Summary

Use a force sensor to investigate and observe changes in the muscular movement of bones during a prolonged period of sustained exertion.

Theory

In this activity, students investigate and observe changes in the muscular movement of bones during a prolonged period of sustained exertion while they:

  • Measure changes in force applied by their thumbs over a period of time
  • Learn that the human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control, coordination, and protection from disease, and that these systems interact with one another
  • Learn that all organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment
  • Gain skills and confidence in using a scientific measurement tool, the force sensor, as well as the graphing capacity of a computer to represent and analyze data

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment to measure force versus time
  • Applying a push to the force sensor for 60 seconds without watching the force graph
  • Applying a push to the force sensor for 60 seconds while watching the force graph
  • Repeating the procedure for all lab group members
  • Using math skills to interpret the force versus time data

Sensors / Equipment Used:

PASPORT Force Sensor

(PS-2104)

Designed to measure both pulling and pushing forces. Uses range from collisions to tug-of-war.
