Assessing Hip and Trunk Flexibility With Modified Sit and Reach Test

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:
1. 'Sit & reach' table
2. Yard stick
3. Assistant.

How to conduct the Modified Sit and Reach Test

Starting position
Modified Sit and Reach 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
Modified Sit and Reach Test
  • Slowly bend and reach forward as far as possible sliding the fingers along the ruler
  • Hold the final position for 2 seconds
  • Record the distance reached to the nearest 1/10 of an inch
  • Repeat the test 3 times and note the best distance.

Analysis

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.
