On Earth, humans experience the effects of gravity pulling on the human body which applies a constant force, or loading effect. This constant force is essential for building the healthy, strong bones we need on Earth. The force can be increased and bones can be made stronger by doing regular weight bearing physical activities such as jumping, walking, running or dancing. This is especially important when humans are young because this is when the skeleton is most responsive to exercise loading. Regular exercise done during youth will compensate for the expected bone loss that occurs as we grow older.
In this activity, students will perform jump training with a rope to improve strength and endurance.
- Improve movement skills and strength and endurance of the heart
and other muscles
- Make and record observations about improvements in jump training
- Jump rope (one per student)
- Watch or stopwatch
- For students: Mission Journal and pencil
- Optional equipment:
- heart rate monitor
- small step, bench or box
