Evaluating Flexibility: Tests and Techniques
Nov 20, 2024
Flexibility Evaluation
Overview
Evaluation of flexibility measures how flexible a person is.
Two main tests discussed: Sit and Reach Test, Goniometry.
Sit and Reach Test
Procedure
Equipment: A box placed against a solid surface.
Participant removes shoes, sits flat-footed, legs straight, knees extended.
Reach as far as possible down the board and hold position for 2 seconds.
Perform three attempts, record the best score.
Advantages
Easy to administer.
Inexpensive equipment.
Provides standardized results.
Disadvantages
Only measures flexibility of lower back and hamstrings.
Not suitable for measuring flexibility of other joints (e.g., shoulders).
Measures only static flexibility.
Requires thorough warm-up for best results.
Key Points
Know how to conduct the test.
Understand the advantages and disadvantages.
Goniometry
Equipment
Goniometer: 360-degree protractor with two arms.
Procedure
Place the center (hinge point) of the goniometer at the center of the joint.
Align the arms with the articulating bones (e.g., humerus, radius/ulna).
Measure the joint angles.
Example: Elbow should reach 180 degrees.
Advantages
Objective measurement.
Provides exact joint angles as data.
Can be applied to any joint, making it sport-specific.
Disadvantages
Human error in finding the center of rotation.
Requires significant training for accuracy.
Conclusion
Both methods provide different insights into flexibility.
Importance of understanding the applications and limitations of each method.
