Summary
This study developed a time-based model to track rugby sevens player injuries. The model accurately predicts team injury burden based on match and training schedules, aiding in injury management.
Area of Science:
- Sports Medicine
- Biomechanics
- Injury Epidemiology
Background:
- Rugby sevens involves high injury rates, necessitating effective management strategies.
- Quantifying injury burden over time is crucial for team performance and player welfare.
Purpose of the Study:
- To develop a novel time-based model for calculating injury burden in international rugby sevens.
- To demonstrate the model's practical application in forecasting and managing team injuries.
Main Methods:
- A descriptive cohort study analyzed injury data from seven seasons of the Sevens World Series.
- Injury incidence rates (match and training) and player recovery rates were quantified.
- A kinetic model integrated injury occurrence and recovery rates to create a time-based injury burden equation.
Main Results:
- Match injury incidence was 108.6 injuries/1000 player-match-hours; training injury incidence was 0.91 injuries/1000 player-training-hours.
- Player recovery followed a first-order rate equation (0.0257 days-1), with a median injury severity of 27 days.
- The model's predicted injury burden closely matched observed data from the Sevens World Series.
Conclusions:
- The model enables governing bodies to assess the impact of tournament scheduling on injury burden.
- Teams can utilize the model to forecast and manage injury burden based on planned training and match loads.
