Data of EMG-Based Attentional Focus Experiments

This file includes experimental data which were measured from 22 male and 13 female healthy volunteer university students (age = 22 ± 3 years, height = 172 ± 8 cm, mass = 69 ± 12 kg). Their EMG signals under various attentional focus conditions were recorded. They were naive to the tasks and none of them were aware of specific purpose of the study. Informed consent was obtained before participation, in compliance with the university’s Institutional Review Board. For the experiments, the subjects were asked to perform weight lifting (2 kg dumbbell) with their dominant hands. The experimental procedure was simply based on up-hold-down exercises (5 s. for each position) repeated 3 times under control, external and internal focus of attention conditions. Each of every measurement took 65 s. in total.
