Summary

Adding an extra step during netball landings does not significantly alter body forces. The run-on landing technique appears most beneficial for reducing lower limb stress.

Area of Science:

  • Sports Biomechanics
  • Netball Performance Analysis

Background:

  • Netball landings involve complex biomechanics.
  • Understanding landing forces is crucial for injury prevention and performance optimization.

Purpose of the Study:

  • To determine if an extra step in netball landings affects body forces.
  • To identify netball landing techniques that minimize stress on the body.

Main Methods:

  • Eighteen netball players performed five landing techniques (pivot, run-on, two-foot, and variations with an extra step) at two pass heights.
  • Ground reaction forces were measured using two force plates.
  • Data were analyzed using ANCOVA, controlling for approach speed.

Main Results:

  • Peak vertical ground reaction forces ranged from 3.53 to 5.74 Body Weight (BW).

Related Experiment Videos

  • Peak braking forces ranged from 0.83 to 1.75 BW.
  • No significant differences in forces were found between legal and extra-step techniques.
  • Run-on techniques showed lower peak forces, longer attenuation times, and lower loading rates compared to pivot or two-foot landings.

    • Conclusions:

    • Taking an extra step provides no biomechanical advantage in netball landings.
    • The run-on landing technique is most effective for reducing lower limb loads.
    • Current netball footwork rules do not require modification based on these findings.
