Validity of Android BarSense Software Used in Some Biomechanical Measurements of Olympic Weightlifting

The aim of this study is to examine the validity of the snatch peak velocity (PW), average velocity (AV), power (PP), average power (AP) and force (F) measurements made with the BarSense software. 34 young weightlifters (mean age 15,97±0,92, height 170,34±6.7, body weight 72,69±14,6) participated in the study voluntarily. Tendo Power and Speed Analyzer was used for reference measurements in the study. Analysis were included the 2 lifts of 70% snatch lifts of 1 repeat maximums. T-Test, Deming Regression, Bland-Altman method were used in the statistical analysis. According to the results of the analysis, it was determined that the difference between BS and TendoPower PV, AV, PP, AP was statistically significant (p <0,05). Although the difference between the F measurements was not significant according to Blant-Altman graph, the concordance between the differences and the averages is not good. The findings of this study show that BarSense software can not be used for PV, AV, PP, AP and Fmeasurements for olympic lifts
