Improving lower-limb stiffness can enhance running economy by optimizing passive force generation. This review explores modifiable factors for better running performance, emphasizing individual runner characteristics.
Area of Science:
- Biomechanics
- Exercise Physiology
- Sports Science
Background:
- Running economy is crucial for distance running performance.
- Passive force generation influences energy cost during propulsion.
- Lower-limb stiffness is a key modifiable factor impacting running economy.
Purpose of the Study:
- To identify modifiable factors that enhance passive force generation.
- To focus on lower-limb stiffness as a trainable attribute.
- To provide insights for optimizing running economy.
Main Methods:
- Comprehensive literature review.
- Analysis of factors influencing lower-limb stiffness.
- Examination of training and biomechanical adjustments.
Main Results:
- Lower-limb stiffness significantly affects running economy.
- Training and biomechanical adjustments can modify lower-limb stiffness.
- No universal guidelines exist; individualization is key.
Conclusions:
- Optimizing lower-limb stiffness is vital for improving running economy.
- Consideration of anthropometric, physiological, and biomechanical traits is essential.
- Personalized approaches are necessary for athletes and coaches.
