Seat and Reach Test 

A measure of hamstring extensibility.

The Seat and Reach Flexibility Test is a widely used assessment that measures an individual's flexibility, particularly in the lower back and hamstring areas. This test is crucial for evaluating overall physical fitness and can provide insights into an individual's potential risk for injuries, especially in activities that require a significant range of motion.

What it Measures and Why it's Important

 

The sit-and-reach test is primarily a measure of hamstring extensibility. While it is often used to assess lower back flexibility, studies show a more moderate correlation with hamstring flexibility.

​

Maintaining good flexibility in the hamstrings and lower back is important for several reasons:

​

  • Injury Prevention: Tight hamstrings and lower back muscles can contribute to back pain and musculoskeletal injuries.

  • Improved Posture: Good flexibility supports proper alignment and can help prevent postural deviations.

  • Daily Function: It allows for a greater range of motion, which is essential for performing everyday activities.

 

It is worth noting that while the test is a valuable tool, it has limitations. Factors like arm, leg, and torso length can influence the results, meaning an individual with longer arms may score higher even if their actual flexibility is not superior.

​How to Perform the Test

 

  1. Preparation: Begin with a short warm-up, and remove your shoes. Sit on the floor with your legs straight out in front of you and your feet flat against a box or wall. Your knees should be fully extended and pressed flat against the floor.

  2. Positioning: Place one hand on top of the other, with your palms facing down.

  3. The Reach: Slowly and smoothly reach forward as far as you can, keeping your knees straight. Your hands should be parallel, and you should not use any bouncing or jerky movements.

  4. Measurement: Hold the final position for about two seconds. The distance reached with your fingertips is measured. Scores can be positive (reaching past the feet) or negative (not reaching the feet).

  5. Scoring: You should perform at least two to three trials, with the best score recorded. The result is typically measured in centimeters or inches.​
