In space, astronauts are in "free-fall" and the normal effects of gravity are absent.
Without the resistance that gravity provides on Earth, astronauts' muscles can get weak.
Because of this, astronauts must exercise on a treadmill or ride a stationary bike
every day while in space. Astronauts also do resistance training with elastic bands
to maintain muscle strength.
Mission:
Learn about resistance training with the elastic bands that astronauts use in space.
Experiment #1
Step 1.
Hold the Thera-Band® with both hands in front of your body.
Step 2.
Pull your hands away from each other, stretching the band across your chest.
Step 3.
Do this 10 times.
Theorize:
Can you feel resistance?
Can you think of other exercises you could do with the Thera-Band® for other parts of your body?
