| Sumario: | The aim of this study was to compare real-time values of power and work obtained through BlueBrainTM and SmartCoachTM systems during
flywheel leg press exercise using different inertias (loads). Eight sets of seven repetitions were performed at variable and maximum intensity for each
inertia used (i.e. 0.0125; 0.025; 0.0375; 0.05; 0.0625 and 0.075 kg*m2), with 2 minutes recovery between sets. Average power during concentric
actions and total work (concentric-eccentric) were measured simultaneously using both systems. Data were analysed using a linear regression analysis
and correlation procedures. Strong significant correlations were observed in average power results between both data acquisition systems for all
individual inertias and intensities evaluated, as well as for overall data (r=.968; Sig.(2-tailed)=.000; R2=.937). In addition, work values showed clear
significant correlations (r=.978; Sig.(2-tailed)=.000; R2=.957). Differences between devices oscillated over a range of 2.6-4.3%. The strong correlations
found in power and work values seem to indicate that both data acquisition systems are similar and valid to estimate power and work during resistance
exercises employing flywheel inertial technology. Thus, both devices may represent a helpful tool to control and follow up training using flywheel
technology. |
