Summary
Modified sit-and-reach tests offer a more comprehensive flexibility assessment. This protocol helps evaluate the impact of erector spinae, hip rotators, hamstrings, and gastrocnemii muscles on flexibility scores.
Area of Science:
- Kinesiology
- Biomechanical analysis
- Sports medicine
Background:
- Strength and aerobic training can reduce erector spinae and hamstring flexibility.
- Reduced flexibility in these muscles increases injury risk.
- Standard sit-and-reach tests provide only a single flexibility measurement.
Purpose of the Study:
- To introduce modifications to the standard sit-and-reach protocol.
- To enable a more detailed assessment of lower back and hamstring flexibility.
Main Methods:
- Utilized a multitest flexometer for 6 distinct flexibility measurements.
- Included standard active and passive sit-and-reach tests.
- Developed modified active and passive tests with slackened external rotators, and further modified tests with slackened hamstrings, gastrocnemii, and external rotators.
Main Results:
- The modified protocol allows for the assessment of flexibility influenced by specific muscle groups.
- Differentiates the contribution of erector spinae, hip rotators, hamstrings, and gastrocnemii.
Conclusions:
- This enhanced sit-and-reach protocol provides indirect assessment of key muscle group influence on flexibility.
- Offers a more nuanced understanding of factors affecting sit-and-reach performance.
