Intelligent Physical Exercise Training in a Workplace Setting Improves Muscle Strength and Musculoskeletal Pain: A Randomized Controlled Trial

Table 2

Delta values (follow-up values minus baseline values). Data are shown as mean ± SD. 3 mt = 3 months. 7 d = 7 days. TG = training group, TG ≥ 70% = participants in TG with an adherence of 70%, and CG = control group. = significant between groups’ effect (test of one-sided hypothesis). § = significant within group effect.
