Table 1 provides a comprehensive overview of performance across the load configurations used in this study, including the average force and power generated at each load, as well as the E/C ratio. A comparative analysis of force measurements between the criterion method (MuscleLab) and the practical method (HandyGym) is presented in Table 2. Bias values range from \"moderate\" to \"large\" across different conditions, indicating a significant standardized difference between the criterion and practical measures. The TEE also ranges from \"moderate\" to \"large,\" suggesting moderate accuracy in the practical measure's estimation. The Pearson correlation coefficient shows a strong relationship between the two measures, with values ranging from \"very large\" to \"nearly perfect\", confirming a robust association between the variables. All \(p\)-values associated with the correlations are highly significant (\(p<0.001\)). \begin{table}
