Subject Area

Physical Education

Grade(s)

9, 10, 11, 12

Overview

This TED-Ed learning activity unpacks muscle fatigue resulting from lifting weights. The first time feels easy, but each lift takes more and more effort until you can’t continue. Inside your arms, the muscles responsible for the lifting have become unable to contract. What’s going on? Christian Moro explains how exactly our muscles operate, and what causes them to become fatigued.

The activity includes a video, multiple choice and open-ended questions, additional resources to dig deeper, and a guided discussion.

This alignment results from the ALEX Health/PE COS Resource Alignment Summit.
