JEPonline 2015;18(3):101-111. This study tested the effect of the including resistance training exercises (RE) in company exercise programs on strength, pain, and perception of mood. Twenty workers (24.5 ± 1.5 yrs old) were randomly divided into experimental group (n = 10) and control (n = 10). While the control group remained with 5 weekly sessions of stretching (15 min long), the experimental group replaced 3 of the sessions with a RE protocol (3 sets, 5 exercises of the large muscle groups that was 15 min long) that lasted 8 wks. Body composition, maximum strength, and questionnaires on pain sensation (NMQ - Nordic Musculoskeletal Questionnaire) and mood (POMS - Profile of Mood States) were taken after 4 wks and at the end of training. The experimental group showed an average strength gain of 22.9 % compared to 4% in the control group. The strength gain was followed by a significant decrease in the fatigue scale of the mood test and a reduction in body pain, with no changes in the control group. There was no change in body composition in either group. The findings indicate that the inclusion of 3 weekly sessions of RE lasting 15 min promotes additional health benefits to a company’s exercise program.
