Abstract
Aim: To evaluate the effect of a
Workplace Physical Exercise Program (PEFAT) on the quality of life (QoL) of
administrative technical staff. Methods: Twenty-six sedentary or
insufficiently active employees evaluated by the IPAQ criteria were divided
into experimental and control groups. To assess QOL, the WHOQOL-bref questionnaire was applied. The intervention was
performed with 10-minute sessions, three times a week, for 12 weeks, totaling
36 exercise classes or 6 hours. Results: No difference was observed in
the facets of each QoL domain (General, Social Relations, Psychological,
Physical and Environment) after the intervention between the groups. Conclusion:
PEFAT in this format was not sufficient to change the QOL of the administrative
technical staff, as QoL is a complex concept, and it is necessary to combine
other programs for a positive result.
Keywords: exercise; quality of life;
occupational health.
Resumo
Objetivo: Avaliar o efeito de um Programa de
Exercício Físico no Ambiente de Trabalho (PEFAT) sobre a qualidade de vida (QV)
dos funcionários técnicos administrativos. Métodos: Participaram da
pesquisa 26 servidores sedentários ou insuficientemente ativos avaliados pelos
critérios do IPAQ, divididos em grupo experimental e controle. Para avaliar a
QV foi aplicado o questionário WHOQOL-bref. A
intervenção foi realizada com sessões de 10 minutos, três vezes por semana,
durante 12 semanas, totalizando 36 aulas com exercícios ou 6 horas. Resultados:
Não se observou diferença na análise das facetas de cada domínio de QV (Geral,
Relações Sociais, Psicológico, Físico e Meio Ambiente) após a intervenção entre
os grupos. Conclusão: o PEFAT neste formato não foi suficiente para
alterar a QV dos funcionários técnicos administrativos, já que a QV é um termo
complexo, sendo necessária a combinação de outros programas para um resultado
positivo.

Work transforms
people's daily lives, covering a large part of the hours of the day in the
workplace, consequently reducing free time for leisure [1], causing stress that
often triggers occupational diseases of physical and/or mental origin,
decreasing the quality of life and productivity [2].
Quality of life
is not only well-being, health status, lifestyle, or mental state, but also
encompasses the individual's subjective perception of their position in life
[3], in the context of the culture and system of values in which they live
concerning their goals, expectations, standards, and concerns [4].
In the work
environment, quality of life involves physical and environmental aspects, as
well as psychological aspects [5,6]. The decrease in the quality of life in the
workplace can leave workers unmotivated and dissatisfied, with high rates of
absences, leaves, turnover, and work accidents, in addition to low productivity
and poor quality in the products and services provided [7].
Several
companies, seeking to improve their production and quality in products and
services, through a more favorable environment for the physical and mental
well-being of their employees, invest in worker health promotion programs aimed
at reducing and preventing occupational diseases [8].
Among the
occupational health promotion programs, those involving physical activity stand
out, such as the Workplace Physical Activity Program (WPAP) [9]. It should be
noted that, unlike Labor Gymnastics, which is usually associated with a
stretching program, WPAP develops in systematic and structured way flexibility,
stretching, relaxation, muscle strengthening, and motor coordination exercises,
through playful activities, performed statically or dynamically, individually
or in groups [8].
Studies linking
short-term WPAP with various aspects that make up the quality of life have been
carried out and point out several benefits of this practice, such as reduced
levels of anxiety [10], improvement in fine motor coordination [11] and in the
mood state enhancing positive mood, vigor [12], decreasing medical certificates
for systemic and musculoskeletal diseases [6], preventing repetitive strain
injuries (RSI), work-related musculoskeletal disorders (WMSD) and improving
interpersonal relationships [13], in addition to the change in the working
environment due to the decrease in tension [1].
But it is
questioned whether WPAP can directly influence the quality of life of a
company's employees. Therefore, this study aimed to verify the effect of a
physical activity program in the work environment on the quality of life of
administrative-technical employees of the Universidade
Federal da Fronteira Sul.
The study has an
experimental design [14], in which a pre- and post-assessment of quality of
life was applied, after 36 classes, for 12 weeks, three times a week of WPAP.
This research
was approved by the Research Ethics Committee (CEP) of the Universidade
Federal da Fronteira do Sul, CAAE No.
53085216.5.3001.5564. All participants signed the free and informed consent
form, and all norms of National Health Council resolution 466/12 were
respected.
Seventy-five
technical-administrative servants from the Universidade
Federal da Fronteira Sul (UFFS), Chapecó/SC,
were invited to participate in the study. The study group was selected
according to the following precepts: an invitation, as well as disclosure at
UFFS, and an applied anamnesis to identify the age and if they practiced physical
activity regularly to define the participants. Were excluded from the study: 1)
individuals who attended less than 75% of WPAP classes; 2) who demonstrated
changes in the levels of physical activity practice during the study; 3) who
had some type of injury during the study period.
The study group
consisted of 26 technical servants from administrative sectors aged between 19
and 45 years, considered as sedentary or insufficiently active A or B according
to the criteria of the International Physical Activity Questionnaire (IPAQ)
reduced version VIII. The groups were equally separated through a simple draw,
with 13 members in the Control Group (CG) and 13 in the Experimental Group
(EG), as described in figure 1.
Figure 1 - Experimental
study design
Three collection
instruments were used: 1) anamnesis to characterize and define the subjects, as
well as to assess body mass expressed in kilograms (kg) and height expressed in
meters (m), used to calculate the Body Mass Index (BMI = Body Mass/(Height²);
2) the reduced IPAQ version VIII, to check the level of physical activity,
according to the classification: a) Irregularly active: those who perform
physical activity for at least 10 continuous minutes, however insufficient to
be considered active. It is subdivided into Irregularly active A: meets at least one of the recommendation criteria
regarding frequency (5 days/week) or duration (150 minutes/week) of physical
activity; Irregularly active B: does not meet any of the recommendation criteria
regarding frequency or duration, but practiced the 10 continuous minutes of
physical activity; and b) Sedentary: one who did not perform any physical
activity for at least 10 continuous minutes during the week [15].
To assess the
quality of life, the World Health Organization Quality of Life-Bref (WHOQOL-Bref) questionnaire
of the World Health Organization [16] was applied, which considers the last two
weeks of the study subjects and is performed in a self-assessment manner for
the Physical, Psychological, Social Relationships, and Environment domains. In
total, 26 questions are answered on a Likert scale from 1 to 5, considering 1
for levels as very low, very dissatisfied, and nothing, and 5 for levels as
very good, very satisfied, and extremely.
The intervention
was carried out with 10-minute physical exercise sessions according to the WPAP
proposal [8]. These classes were divided into three stages: 1) initial part of
3 to 5 minutes in duration, with warm-up exercises; 2) main part of 4 to 6
minutes, with flexion exercises and muscle strengthening; 3) final part of 1 to
4 minutes, with relaxation and stretching exercises. Classes took place three
times a week for 12 weeks, totaling 36 classes or six hours of activities
(Table I).
Table I - Description
of activities proposed in the intervention (intervention protocol)
Adapted from Laux, Corazza, and Andrade [8].
For controlling
the intensity during the proposed activity, the Borg Rating of Perceived
Exertion scale [17] was used so that the subject evaluates their perception of
exertion between mild and intense (13-15 points).
For data
analysis, descriptive and inferential statistics were used. Comparisons between
groups were performed using the t-test for independent samples and comparing
description variables, the ANOVA and Friedman test for comparison between
periods (pre and post), and between groups, Bonferroni’s Post Hoc. In comparing
physical activity levels, the Chi-square test was used. The tests were performed
using the Statistical Package for Social Sciences (SPSS®) version 21.0 for
Windows®, with a significance level of 5%.
Table II shows
the characterization data of the 26 administrative technicians who participated
in the study, with an average age for the EG of 30.12 ± 7.4 years, while the
average age of the CG was 30.49 ± 5.63 years, classified as sedentary or
insufficiently active. It is observed that there is no difference in the
characterization variables when compared between CG and EG.

Activity Questionnaire
Table III shows
the frequencies and percentages of perception of administrative technicians on
the general questions (Q1 and Q2) of the WHOQOL-Bref.
It was observed in these results that 13.5% of administrative technicians
considered their quality of life poor, while 59.6% considered it positively,
and from these, 51.9% rated their quality of life good, and 7.7% rated it very
good.
In the question
about the level of satisfaction with health, it was found that 3.8% of
technicians are very dissatisfied, 17.3% are dissatisfied, and 53.9% consider
their health positive, and from these, 38.5% are classified as satisfied and
15.4% very satisfied.

This study
analyzed the effect of a Workplace Physical Activity Program (WPAP) on the
quality of life of administrative-technical employees at the Universidade Federal da Fronteira
Sul, Chapecó/SC, and no difference was observed in
the quality of life between the control and experimental groups. Furthermore,
most employees considered their quality of life as good (59.6%) and reported
satisfaction with their health (53.9%).
In a study like
this one, carried out by Freitas-Swerts and Robazzi [18], who evaluated the effect of a compensatory
labor gymnastics program in workers, the labor gymnastics promoted a reduction
in spine pain, but without a reduction in levels of occupational stress. One
justification would be the occupational stressors that are often related to the
organization of the work environment, such as pressure for productivity,
retaliation, unavailability of training and guidance, abusive relationship
between supervisors and subordinates, and inadequate work/rest cycles [19].
Freitas-Swerts and Robazzi [18] justify
that this scenario favors responses in the short and long term, which increases
the possibility of developing different pathologies of occupational origin,
affecting the physical and psychological health of employees, which can lead to
human and economic losses due to occupational stress.
Another study
like the present one was carried out by Candotti, Stroschein, and Nol [20], in
which they evaluated the effect of labor gymnastics on back pain and postural
habits of workers in the administrative sector, who stay for long periods in
the sitting position, with sessions consisted of stretching, flexibility,
resistance, relaxation, and joint mobilization exercises, lasting 15 minutes,
three times a week for three months. The results showed that after the
gymnastics sessions, the experimental group showed a decrease in the intensity
and frequency of referred pain (20% without pain in each region: neck and back,
and 93.3% mild pain in each region: arm, wrist-hand, and leg) and change of
postural habit during work, improving their sitting posture. The authors
clarify that labor gymnastics acts as an educational action, making
practitioners aware of health promotion and quality of life.
The study by
Grande et al. [1] investigated the determinants of quality of life.
After three months of health promotion programs for 190 workers from 4
companies. Company A received interventions with labor gymnastics plus
educational programs, B only labor gymnastics, C only educational programs, and
D without intervention (control). Only the occupational environment domain
showed changes in companies A and B. The perception of the workers' quality of
life, as well as the health domain, showed no differences between companies,
like the one in the present study.
Therefore, it
can be understood that there is no standard of quality of life that can be
satisfactory to all employees, as everyone has different needs. Thus, what is
needed is to have a good quality of life management within the organization
[21], creating a more productive and pleasant environment.
However, unlike
this study, Vigário et al. [22] addressed the quality-of-life
issue with exercise programs of longer duration with patients with
differentiated thyroid carcinoma and undergoing treatment for TSH suppression.
This was developed with long sessions (60 minutes of aerobic activities and
stretching, twice a week for 12 weeks), with the outcome of improving
health-related quality of life, by minimizing the side effects of treatment
with suppression of TSH.
In this context,
Tairova and Lorenzi [23]
reinforce that regular physical activity of light to moderate intensity with
60-minute sessions three times a week positively influences the quality of life
and the climacteric symptoms intensity in postmenopausal women.
The results of
the present study, with no difference in the quality of life after 12 weeks of
WPAP in administrative-technical servers, may have been due to the intervention
of this program having focused only on the physical exercise program in the
work environment to assess the quality of life, without considering other
aspects of daily life that influence the quality of life, such as work
motivation, recognition, remuneration and additional perspectives of social
life and relationships [24].
Studies with the
same intervention protocol (including application time) found a reduction in
anxiety [10] and in medical certificates [6], improvement in reaction time [5],
and in the mood [12] of administrative-technical servers in a federal university.
It was expected, therefore, that for this variable, quality of life, a positive
effect would also be observed after the protocol application.
However, the
term quality of life is broad and includes several variables, which was cited
by Martins and Michels [25], revealing examples found
in companies in Brazil and around the world, which implemented or expanded the
worker's health promotion program, emphasizing key points to improve program
performance such as program communication; health, hygiene, and safety; medical
exams; healthy eating; alcoholism; physical exercise, among others, and
complements the study by stating that the program must link objectives related
to health, environment, and human resources, that is, programs to promote
workers' health must involve several activities to achieve a quality of life.
The Workplace
Physical Activity Program with 10 minutes of intervention, three times a week
for 12 weeks, showed no difference between the control and experimental groups
concerning the quality of life. This result may be associated with the
complexity of the “Quality of Life” concept, and due to this factor, further
research is needed with strategies that can be considered and scientifically
validated.
