Ecological Validity and Reliability of the Rugby Sevens Simulation Protocol
International Journal of Sports Physiology and Performance
|December 8, 2015
Summary
The Rugby Sevens Simulation Protocol (R7SP) accurately mimics match play demands and shows good reliability for research. This simulation is a useful tool for detecting performance changes in rugby sevens athletes.
Area of Science:
- Sports Science
- Exercise Physiology
- Rugby Research
Background:
- Rugby sevens demands high intensity activity with frequent accelerations and decelerations.
- Accurate simulation protocols are crucial for evaluating player performance and training interventions.
Purpose of the Study:
- To determine the ecological validity of the Rugby Sevens Simulation Protocol (R7SP).
- To assess the interday reliability of the R7SP for research applications.
Main Methods:
- Ten male rugby players (20 ± 2 y) underwent two R7SP trials separated by seven days.
- Continuous heart rate monitoring and GPS tracking recorded movement and intensity.
- Blood lactate and rating of perceived exertion were measured pre- and post-halves.
Main Results:
- The R7SP replicated key match activity profiles and heart rate responses.
- Most variables showed a coefficient of variation (CV%) below 5% between trials.
- Blood lactate (14-20% CV) and time above 90% maximal HR (26% CV) were less reliable.
Conclusions:
- The R7SP is ecologically valid, mirroring rugby sevens match play demands.
- The protocol demonstrates good interday reliability for use in research settings.
- R7SP can effectively detect meaningful changes in performance variables.
