Abstract

In this study the prediction of maximum performance in dumbbell concentration curl and shoulder press was examined. The idea of the study was to predict the one repetition maximum (1-RM) with help of analysis of accelerations during a submaximal lift. In the study 30 gym trainees (all males, age 26±7 years, height 179±6 cm, weight 77±10 kg) performed dumbbell concentration curl and shoulder press exercises which all were accurately measured with help of a specific three-dimensional acceleration sensor based analysis system. The characteristics of the acceleration as a function of submaximal weight was analyzed and the prediction of one repetition maximum were evaluated. The data analysis resulted in 1-RM prediction mean absolute error of 2,8 kg for the dumbbell concentration curl and 12,3 kg for the shoulder press when using a simple linear prediction model. The detailed analysis showed that prediction mean absolute errors of 1,9 kg and 3,3 kg for dumbbell concentration curl and shoulder press would be achieved by adjusting the prediction model appropriately. The results show that it is possible predict the 1-RM with help of accelerometer from the submaximal performance in studied weight lifting exercises. However, the detailed prediction algorithm for 1-RM prediction requires further development.
