Introduction
Improving flexibility is a key component of physical fitness, contributing to better performance and reduced risk of injury. Various methods and techniques have been studied to determine the most effective ways to enhance flexibility.
Key Insights
-
Contract-Relax (CR) Method vs. Ballistic Stretching (BS)
- The CR method is significantly more effective than the BS method for improving muscle flexibility. Training three times a week with the CR method showed the best results, and even once a week was sufficient to maintain flexibility improvements.
-
ACSM Flexibility Training Recommendations
- The American College of Sports Medicine (ACSM) recommendations for flexibility training, which include stretching major muscle groups three times a week, are effective in improving hip flexion range of motion. No significant differences were found between different stretch techniques (passive or active) or durations (15, 30, or 45 seconds).
-
Warm-Up and Stretching
- Both jogging before stretching and stretching alone significantly improve flexibility. However, jogging before stretching showed a significant gain in ankle flexibility, while stretching alone was more effective for trunk flexibility.
-
Eccentric Training vs. Static Stretching
- Both eccentric training and static stretching significantly improve hamstring flexibility, with no significant difference between the two methods.
-
Mind-Body Techniques
- Neuro Emotional Technique® (NET), a mind-body approach, significantly improves general flexibility compared to both active and passive control groups.
-
Flexibility Training in Older Adults
- A 10-week flexibility training program significantly improves spinal mobility in older women, suggesting that age does not limit the potential for flexibility gains.
-
Dynamic Flexibility Training
- Dynamic flexibility training is effective in improving flexibility and is commonly used in athletic training programs to prevent injuries and enhance performance.
-
Postisometric Relaxation and Static Stretching
- Postisometric relaxation, static stretching combined with stabilizing exercises, and stabilizing exercises alone all improve one-joint hip flexor flexibility. However, only static stretching combined with stabilizing exercises significantly improves two-joint hip flexor flexibility.
-
Stretching Duration
- Longer stretching durations lead to greater improvements in flexibility. Stretching for 60 minutes per day showed the highest increase in flexibility compared to shorter durations.
-
Types of Flexibility Training
- Passive static stretching (PSS) is the most effective method for improving both active and passive hip range of motion compared to hold-relax (HR) and active isolated stretching (AIS).
Conclusion
The most effective way to improve flexibility involves a combination of methods. The contract-relax method, ACSM recommendations, and passive static stretching are particularly effective. Additionally, incorporating dynamic flexibility training and mind-body techniques like Neuro Emotional Technique® can further enhance flexibility. Longer stretching durations and consistent training are crucial for significant improvements.
