Reliability Of The Output Sports Inertial Measurement Unit In Measuring A Reactive Strength Index From The Drop Jump And 10-5 Rebound Jump Test

This dataset was used to examine the trial-to-trial reliability and usefulness of the Output Sports inertial measurement unit (IMU) in measuring reactive strength index (RSI) derived from the drop jump (DJ) and 10-5 rebound jump test (10-5 RJT). Twenty-three male elite intercounty hurlers (mean [SD]; Age: 24.3 [3.7] years, Mass: 88.0 [6.3] kg, Height: 183.8 [5.8] cm, Experience at elite level: 5.8 [3.8] years) performed three trials each of the DJ and 10-5 RJT, on familiarisation and testing days. There was one-week between familiarisation and testing. All participants completed the DJ protocol however only twenty of the twenty-three participants completed the 10-5 RJT protocol testing.
