本研究的目的是开发一个上肢肌肉力量（PUL）预测模型，使用实心球投掷测试（MBT）的橄榄球运动员。18名业余橄榄球运动员进行了MBT测试和指导下的卧推运动在30，40，50和60%的1。将Myotest®加速度计定位在卧推杆上以估计肌肉力量。使用线性回归从MBT距离推导上肢肌力预测方程。残差分析使用Myotest®获得的值估计预测值的残差。Bland-Altman图用于验证实际和预测上肢肌肉力量之间的一致性，包括绝对瓦特（W）和相对项（W/kg无脂肪质量）。在30%、40%和50%的强度下，实际和预测上肢肌肉力量之间分别存在显著相关性（r = 0.834、0.854和0.872）。预测值的绝对偏差为-1.87 W（p <0.05）。对于预测的肌肉力量相对于无脂肪质量，偏差为0.782 W/kg（p <0.05）。结论：MBT测试与实际PUL值具有高度相关性，并且发现本研究中开发的方程对预测男女橄榄球运动员的PUL具有较高的准确性。
The aim of this study was to develop an upper limb muscle power (PUL) prediction model using the Medicine Ball Throw Test (MBT) in rugby players. Eighteen amateur rugby players underwent the MBT test and the guided bench press exercise at 30, 40, 50 and 60% of 1. Myotest® accelerometer was positioned on the bench press bar to estimate muscle power. Linear regression was used to derive the upper limb muscle power prediction equation from the MBT distance. The residue analysis estimated the residual error of the predicted values using values obtained by Myotest®. Bland-Altman plots were used to verify agreement between actual and predicted upper limb muscle power, both in absolute Watts (W) and relative terms (W/kg of fat-free mass). There were significant correlations between actual and predicted upper limb muscle power (r = 0.834, 0.854, and 0.872) for intensities of 30%, 40% and 50%, respectively. Absolute bias of predicted values was -1.87 W (p <0.05). For muscle power predicted relative to fat-free mass, bias was 0.782 W/kg (p <0.05). Conclusion: The MBT test has high correlation with actual PUL values and it was found that the equation developed in this study has high accuracy to predict PUL in rugby players of both sexes.
