Background: Beneficial effects that physical exercise has on the physical and emotional condition that a worker can have in the interaction with their work environment are recognized. Studies show that sedentary lifestyle leads to an increase in fat mass or alterations in physical condition, negatively influencing worker/work environment interaction (Williams, 2019).

Purpose: The aim of the study was to describe the effects of implementing 3 physical exercise programs (aerobic, anaerobic, concurrent) on dimensions of the mood states profile of administrative workers from an University.

Methods: 24 workers are chosen to form 4 groups: control group without participation in exercise programs; experimental group A, aerobic exercise, 12 total sessions, 3 sessions/week, load intensity 60 - 75% Maximum Heart Rate - MHR, 45 minutes duration/session; experimental group B, anaerobic exercise, 12 total sessions, 3 sessions/week, load intensity 70 - 85% MHR, 30 minutes duration/session, and group C, concurrent exercise, 12 total sessions, 3 sessions/week, load intensity 60-80% MHR, 40 minutes duration/session. Body composition variables (weight, %fat/fat free mass) are evaluated by Tánita BC 547 tissue impedance technique and Physical Condition (aerobic capacity, muscular aptitude, balance and flexibility), using modified Eurofit battery, moments before/after implementation of exercise programs in all the subjects. Dimensions of mood states profile (Tension, Vigor, Depression, Fatigue, Anger, Confusion) were evaluated during 6 moments; pre-implementation of exercise programs, at the end of each week of exercise development and at the moment after implementation of exercise programs, by POMS test - Profile of Mood Profile test, full version (McNair, 1971). Unpaired T Student is developed to compare results after implementation of exercise in physical condition/body composition of each group with respect to the control. Repeated measurement ANOVA is developed - intra/intergroup comparison.

Results: None of the experimental groups (A, B and C groups) showed significant differences in Body Composition/Physical Condition compared to the Control group. Group C individuals showed a significant increase in Tension and Vigor dimensions (p=0.001) compared to other groups. Group B participants show significant decrease in Depression dimension, (p=0.001) compared to other groups. Group A individuals show significant decrease (p=0.001) in Fatigue, Anger and Confusion dimensions compared to other groups.

Conclusion(s): It is concluded that changes in dimensions evaluated are not due to changes in Body Composition/Physical Condition, but due to the humoral response. The increase in Tension and Vigor dimensions would be mediated by synthesis of Catecholamines, Beta-endorphins and Serotonin, depending on the load intensity of concurrent exercise. The decrease in dimensions of Fatigue, Anger and Confusion is due to the duration of each aerobic exercise session, increasing Beta-endorphins and Serotonin. The changes in Depression dimension due to anaerobic exercise are explained by high load intensity that increases Syntesis of Beta-endorphins and Catecholamines (Dromonkov, 2017; Gilian et al, 2019).

Implications: The importance of implementing self-care spaces in workers is generated, promoting beneficial effects at the physical and emotional levels, as part of the work of Physical Therapy in Occupational Health directly and undirectly in Mental Health.
