Kinematic bidimensional analysis of the propulsion technique in wheelchair rugby athletes

Eur J Transl Myol, 2020 · DOI: · Published: March 3, 2020

Simple Explanation

This study analyzes the propulsion techniques used by wheelchair rugby athletes to understand how these techniques impact their upper limbs and potentially lead to shoulder pain. The research focuses on kinematic parameters, such as angles and range of motion, during sprint and Wingate tests to identify potentially harmful movement patterns. The findings suggest that athletes with lower motor abilities use a semi-circular pattern that is considered more protective, while those with higher motor abilities use an arcing pattern that can increase speed but may also increase stress on the shoulder joint.

Participants

13 athletes from the Italian National Wheelchair rugby team

Evidence Level

Key Findings

1
Most wheelchair rugby athletes, especially those with lower functional abilities, use a semi-circular propulsion technique.
2
Athletes with higher motor abilities tend to use an arcing pattern, which is associated with greater speed but potentially higher stress on the shoulder joint.
3
During the sprint test, release angles increased and contact angles decreased, resulting in an overall increase in total push angles.

Research Summary

This study investigated the propulsion techniques of wheelchair rugby athletes to identify factors contributing to upper limb stress. The research found that athletes with lower motor abilities tend to use a semi-circular propulsion technique, while those with higher motor abilities use an arcing pattern. The study suggests a need to balance protective techniques with optimal sport performance to prevent shoulder pain in wheelchair rugby athletes.

Practical Implications

Injury Prevention Strategies

Implement training programs that emphasize protective propulsion techniques to reduce the risk of upper limb injuries, particularly shoulder pain.

Wheelchair Customization

Tailor wheelchair setup and configuration to individual athletes' abilities and propulsion styles to minimize stress on the shoulder joint.

Performance Optimization

Develop strategies that balance protective techniques with the need for speed and performance in wheelchair rugby.

Study Limitations

1
The sample size of 13 athletes may limit the generalizability of the findings.
2
The study focused on kinematic parameters, and did not directly measure shoulder joint loading or muscle activity.
3
Further research is needed to investigate the long-term effects of different propulsion techniques on shoulder health.
