An Incremental Shuttle Wheel Test for Wheelchair Tennis Players

Area of Science:

• Sports Science
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Wheelchair tennis is a demanding sport requiring significant physical exertion.
• Assessing the physiological demands and performance metrics of wheelchair athletes is crucial for training and evaluation.

Purpose of the Study:

• To investigate the correlation between shuttle wheel test (SWT) outcomes and peak oxygen uptake (VO2peak) in wheelchair tennis players.
• To determine if SWT and VO2peak can differentiate between various skill levels of wheelchair tennis athletes.

Main Methods:

• Fifteen wheelchair tennis players underwent a shuttle wheel test (SWT) on a tennis court.
• Continuous measurement of oxygen consumption (VO2) determined VO2peak and achieved stage.
• Spearman correlation analyzed relationships between outcomes and Dutch wheelchair tennis ranking; independent t tests compared national and international players.

Main Results:

• Moderate correlations (r = .40-.47) were observed between VO2peak and SWT outcomes.
• The tennis ranking showed a weak correlation with VO2peak (r = -.35) but a strong correlation with SWT outcome (r = -.80).
• Significant differences in achieved stage (P = .027) and VO2peak (P = .027) were found between national and international players.

Conclusions:

• Shuttle wheel test (SWT) outcomes explain limited variance in VO2peak, suggesting it's not a valid test for aerobic capacity.
• However, SWT outcomes strongly correlate with wheelchair tennis skill level, providing a good measure of peak wheelchair performance.
• The study highlights significant performance differences between national and international wheelchair tennis players.
