The present study aims to compare the differential effects of a mindfulness-based intervention (MBI) and physical exercise (PE) on different stress and health variables by self-reports. A randomized controlled trial of three groups is proposed, with pretest, posttest and four follow-ups at 1, 2, 3 and 6 months that would be developed among the employees of two large multinationals.
Work and workplace related problems are common sources of stress. Work-related stress is associated with a decrease in productivity, greater absenteeism, accidents and injuries, mental illness, greater errors, and poor performance, among others, which involve significant financial costs. Therefore, it is crucial to find coping strategies that are effective in reducing such stress. Probably, the most appropriate strategies, for their real possibilities of implementation, for their easy execution, low cost and for the empirical support they have, are mindfulness-based interventions (MBIs) and physical exercise (PE). Both types of practices have shown beneficial effects for physical health, mental health and psychological well-being in general. Different investigations have compared the implementation of MBI and PE, both combined and separately, with interesting results. The main objective is to evaluate the interactive effects of group x time, the intragroup changes and the differences between groups, in the different moments (pretest, posttest, 1, 2, 3 and 6-months follow-up) on general health, stress, affective job satisfaction, recovery, work performance, and positive and negative affect in the three groups considered; an MBI, an aerobic PE program and an inactive control / waiting list (LE) condition will be contrasted. The secondary objective is to evaluate the trend and linear patterns in the change trajectory in the three groups during the eight weeks of intervention on fatigue, psychological distancing, sleep, work stress, and attention. A randomized controlled trial of three groups is proposed, with pretest, posttest and four follow-ups at 1, 2, 3 and 6 months that would be developed among the employees of two large multinationals (N ≥ 150). The primary dependent variables considered are: 1) recovery experiences; 2) perceived stress; 3) general health; 4) affective job satisfaction; 5) individual work performance; and 6) positive and negative affects. The secondary dependent variables considered are daily states of: 1) fatigue, 2) psychological distancing, 3) quality of sleep; 4) work stress; and 5) attention. Sociodemographic data will be collected at baseline (age, gender, level of education, number of economically dependent persons, type of contract, type of working day (split/continuous), workstation type, seniority in the organization, seniority in current position and teleworking modality). The investigators identified two candidate covariates: 1) pharmacological treatment that can influence the psychological state (measured with two alternatives, use / non-use of anxiolytics, hypnotics and other psychotropic drugs); 2) Baseline state of stress and work stress (measured using a single item scale, Likert scale from 1 to 5, 1 being very low and 5 very high) The intervention program is structured for 8 weeks, during which the two intervention groups will carry out their recovery strategy (IBM or EF), starting and increasing the practice 5 minutes every two weeks (weeks 1 and 2, 15 minutes; weeks 3 and 4, 20 minutes; weeks 5 and 6, 25; weeks 7 and 8, 30 minutes). The control group will continue as usual. Record will be taken of recovery strategies that workers perform naturally and spontaneously, and will be compared to strategies guided by interventions, as those the investigators propose. The investigators believe that this study is a quasi-pioneering initiative because of its theme, uses a robust methodology, and will have an important scientific-technical impact. The importance of the topic addressed in terms of health and business productivity is associated with important contributions in terms of knowledge transfer to companies and society in general.

An instructor trained in Mindfulness-based Stress Reduction (MBSR; Kabat-Zinn, 1990) will conduct meditations lasting 15 to 30 minutes. The participants will have a mobile application designed ad hoc with the practice of the week so they can do it individually at home.
An aerobic and fitness trainer will conduct aerobic exercise lasting 15 to 30 minutes. The participants will watch it in a video platform. They will not be able to do anaerobic exercise like weight lifting. The intensity of the chosen exercise will be moderate, maintaining between 120-140 beats per minute.

Change in General Health with six time points data.
The General Health Questionnaire (GHQ-12) consists of 12 items. It is a unidimensional measure of psychological distress. It is answered on a Likert-type scale from 1 to 4 (1 = Never and 4 = Always). The score was used to generate a total score ranging from 0 to 36.
Time frame: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
Change in stress with six time points data.
A single item was used: Stress refers to a person's situation when they feel tense, restless, nervous, or anxious, or are unable to sleep at night because their mind is constantly preoccupied with work-related issues. Please indicate the extent to which you currently feel this type of stress. It has five possible responses on a Likert-type scale from 1 to 5 (being 1 nothing and 5 a lot)
Time frame: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
Change in Affective Job Satisfaction with six time points data.
The Brief Index of Affective Job Satisfaction (BIAJS)-Spanish version (BIAJS) consists of 7 items. It is an overall measure of affective job satisfaction. It measures satisfaction in five facets: promotion, co-workers, work itself, supervision and salary. It is answered on a Likert-type scale from 1 to 5 (1 = Strongly disagree and 5 = Strongly agree). The score was used to generate a total score ranging from 7 to 35.
Time frame: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
Change in Need for Recovery with six time points data.
The Need for Recovery (NFR) Scale consists of 9 items. It facilitates the understanding of the factors that can lead to sustainable working and employability. It is answered on a Likert-type scale from 1 to 5 (1 = Never and 5 = Always). The score was used to generate a total score ranging from 1 to 100.Our research team will carry the validation of the Spanish version of NFR.
