초록

Objective: The aim of this study was to explore the relationship between rate of force development (RFD) and force control accuracy during isometric mid-thigh pull (IMTP). Method: Nine healthy young males (22.0 ± 1.2 y; 174.8 ± 3.9 cm; 72.5 ± 5.5 kg) participated in this study. Participants first completed maximal effort IMTP to obtain RFD, then performed 20 seconds of force control tasks at 10% and 40% of individual peak force with real-time visual feedback. Force control accuracy was quantified using root-mean-square error (RMSE) and relative RMSE (rRMSE). Pearson correlations tested associations between RFD and force control accuracy (α = .05). Results: RFD showed significant positive correlations with both force control accuracy at 10% (RMSE: r = .715, p = .031; rRMSE: r = .772, p = .015) and 40% (RMSE: r = .708, p = .033; rRMSE: r = .748, p = .021) conditions. Conclusion: Our findings indicated that greater RFD was associated with decreased force control accuracy during IMTP.
