Pre-work baseline values of maximal strength, pressure pain threshold and reference contraction EMG amplitude, and their recovery after work.

a: EMG amplitude expressed in percent of the pre-work reference contraction value.
b: Main effect of TB tested using one sample t-tests for post-work0h and post-work1h values pooled across MT against the reference pre-work value (100); interaction effect (TB × MT) investigated by testing for the effect of MT in three separate ANOVAs on results from post-work0h, post-work1h, and the difference between post-work0h and post-work1h.
MVC, Maximum voluntary contraction; PPT, Pressure pain threshold; MT1, MT2, MT3, easy, medium and difficult mental task; TB, Test battery.
Table shows mean (SD between subjects) values of MVC, PPT and reference contraction EMG amplitude in the three test batteries (TB) preceding work, immediately after work and one hour into recovery after work including the three mental tasks (MT1, MT2, MT3). Right-most columns show results of the ANOVA tests (p-values less than 0.05 in bold) for a main effect of TB and an interaction TB × MT.
