Velocity specificity, combination training and sport specific tasks.

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Velocity-specific resistance training is debated for enhancing functional sporting performance.
• The netball chest pass involves high-velocity movement, contrasting with typical training velocities.

Purpose of the Study:

• To investigate the effect of isoinertial training velocity on netball chest pass throwing velocity.
• To determine if velocity-specific training improves functional sporting performance.

Main Methods:

• Twenty-one female netball players were divided into strength-trained (80% 1RM), power-trained (60% 1RM), and control groups.
• Both training groups underwent a ten-week program combining resistance and sport-specific motion training.
• Pre- and post-training assessments measured weight lifted, power output, and netball throw velocity.

Main Results:

• The strength-trained group showed significantly greater improvements in weight lifted and power output compared to power and control groups.
• Both strength-trained (12.4%) and power-trained (8.8%) groups improved netball throw velocity, with no significant difference between them.
• Training velocity was considerably lower than the actual netball throw movement velocity.

Conclusions:

• The effectiveness of velocity-specific training for improving high-velocity functional sporting movements like the netball throw is questionable.
• Repeated intent to move loads rapidly, combined with sport-specific movements, may be more critical for high-velocity adaptations.
• Coordination and activation patterns are likely key determinants of sport-specific velocity improvements.
