De conclusie van het rapport
Conclusion
This study revealed that commercially available alterations in crank length of ±10 mm had no effect on mean power output during four-minute intervals performed at a heavy intensity. However, shorter cranks may be particularly beneficial for cyclists suffering with overused hip and knee injuries as decreases in hip and knee flexion around the top of the pedal stroke and reduced non-sagittal plane motion were identified when shorter cranks were used. Shorter cranks also significantly increased anterior pelvic tilt, which has been associated with a reduced risk of lower back injury and improved aerodynamics
