Measuring distance thrown during the Seated Medicine Ball Throw (SMBT) has been used frequently within the literature to quantify upper body explosiveness, due to the test being easy to learn, low-risk, and requiring minimal equipment. The reliability of distance thrown in the SMBT has not been broadly reported, nor have familiarization protocols been thoroughly documented. The purpose of this study is to assess the reliability of distance thrown during the SMBT as a representative measurement for upper body explosiveness in active, recreationally trained adults. Before testing, 20 subjects completed a dynamic warm-up. After learning proper technique, subjects were familiarized with the exercise by completing continuous trials using a 10 lb medicine ball, with 1 minute of rest between trials, until three consecutive throws within 0.25 m were achieved. Subjects rested 20 minutes, repeated the warm-up, and then completed 6 trials of the SMBT where distance of each throw was measured. Any trial in which technique deviated significantly from the instructions was repeated. Intraclass correlation coefficients (ICCs) were used to assess reliability between trials. Distances thrown for trials 1-6 were as follows: 3.43±0.99 m, 3.41±0.95 m, 3.48±1.00 m, 3.48±1.00 m, 3.46±1.03 m, and 3.54±1.05 m respectively. ICCs for consecutive trial pairs ranged from 0.97-0.99. These findings suggest that distance thrown is a reliable representative measure of upper body explosiveness in recreationally trained adults. The familiarization protocol used was sufficient for producing consistent performance.
