Assessing Hip and Trunk Flexibility. The objective of this test is to monitor the development of the athlete's hip and trunk flexibility.

Required resources

To undertake this test you will require:
  • 'Sit & reach' table or a bench with a ruler
  • Assistant.

How to conduct the hip and trunk flexibility test?

  • Sit on the floor with the back and head against a wall, legs fully extended with the bottom of the feet against the sit-and-reach box
  • Place the hands on top of each other, stretching the arms forward while keeping the head and back against the wall
  • Measure the distance from the finger tips to the box edge with a ruler. This becomes zero or starting point.
Movement
\Movement position hip and trunk flexibility test
  • Slowly bend and reach forward as far as possible sliding the fingers along the ruler
  • Hold the final position for two seconds
  • Record the distance reached to the nearest 1/10 of an inch
  • Repeat the test 3 times and note the best distance.
