Abstract
Introduction: Due to the
COVID-19 pandemic situation, preventive measures to reduce infection risk were
adopted, such as social distancing and closing commercial activities.
Therefore, stay active at home is recommended to maintain physical and mental
health during this period. Objective: To verify the effect of a
home-based exercise program during the quarantine due to COVID-19 in motivation
and physical performance in recreational female futsal team. Methods:
Nine participants (26.0 ± 4.7 years old) performed four weeks of full-body
training using a circuit resistance training format, three times per week.
Participants performed physical tests (e.g., long jump, abdominal, and upper
limb resistance) pre-and post-exercise-program. In each session were evaluated
the training motivation (Likert Scale 0 to 4) and global effort perception
(Borg 6-20). Results: Only five participants reached 80% of the training
sessions. Current participants reported lower motivation for training through
the weeks and perceived a "moderate" intensity. The performance in
all physical tests increased. Conclusion: The results suggest that the
home-based exercise program during the quarantine due to COVID-19 was
sufficient to increase the physical performance in the recreational female
futsal team. However, the quarantine period may impair the program's adherence
and a decrease in training motivation. Models of protocols based on
psychophysiological responses are encouraged to improving adherence to the
home-based exercise program, especially during the quarantine period.

Resumo
Introdução: Devido a situação pandêmica da
COVID-19, medidas preventivas foram adotadas para reduzir o risco de infecção
como distanciamento social e fechamento das atividades comerciais. Dessa
maneira, recomenda-se permanecer ativo em casa a fim de manter a saúde física e
mental durante esse período. Objetivo: Verificar o efeito de um programa
de exercícios feito em casa durante a quarentena causada pelo COVID-19, na
motivação e no desempenho físico de atletas recreacionais de futsal feminino. Métodos:
Nove participantes (26,0 ± 4,7 anos de idade) realizaram quatro semanas de
treinamento de resistência “full-body”, no formato de
circuito, três vezes na semana. Participantes realizaram testes físicos (salto
horizontal, resistência abdominal e flexão de braço) antes e depois do programa
de treinamento. Em cada sessão foram avaliados a motivação para o treinamento
(Escala likert 0 4) e a percepção de esforço global (Borg 6-20). Resultados: Apenas cinco participantes
realizaram 80% das sessões de treinamento. Os participantes reportaram uma
baixa motivação para treinamento durante as semanas e perceberam as sessões de
treino com “moderada” intensidade. O desempenho aumentou em todos os testes
físicos aumentou. Conclusão: Os resultados sugerem que o programa de
exercícios em casa durante a quarentena, devido a COVID-19, foi suficiente para
aumentar o desempenho físico em uma equipe de atletas recreacionais de futsal
feminino. Entretanto, o período de quarentena pode prejudicar a aderência em programas
de treinamento e diminuir a motivação para prática de exercícios. Modelos de
protocolos baseados nas respostas psicofisiológicas são encorajados de maneira
a aumentar a aderência para treinamento em casa, especialmente durante a
quarentena.

Since the
beginning of 2020, all world was witnessing a transmissible infectious disease,
denominated Coronavirus (COVID-19). This disease emerged from Wuhan, China, and
spread globally, causing threats to human health and lives [1]. Most of the
countries implemented quarantine and social isolation measures as preventive
measures. Also, preventive measures included closing commercial activities. In
the sport settings, ongoing championships and international events were
postponed [2], and organized training sessions or practice were forbidden,
especially team-modalities [3].
Meanwhile, the
recommendations suggested for elite athletes to continue their training session
at home, considering the impact of detraining in their physiological and
physical performance, immune systems, and mental state [4-6]. Coaches have
proposed home exercise strategies; however, implementing sport-specific
exercise and the absence of official sports facilities make it difficult to
provide training options compared to those adopted under normal circumstances
[2].
For the amateur
or recreational category, the difficulties mentioned above seem to increase.
Coaches and athletes have fewer resources to implement training sessions, as
well as the control of athletes' motivation to continuing to train during this
quarantine. As previously reported in the literature, both men and women elite
athletes have a higher motivation for training compared to non-elite [7,8].
Maybe because they do not depend directly on sport-resources, the commitment
and motivation to training in amateurs and recreational athletes could be
inferior compared to elite athletes.
Therefore,
considering that exercise during the quarantine has been highly recommended,
especially in the sport setting, and considering that recreationally athletes
may suffer more difficulties in training than elite athletes, special attention
is necessary for this group. Thus, the main aim of this study was to develop a
suitable home-based exercise program for a recreational futsal female team
during the quarantine due to the COVID-19 outbreak and verify the effect of
this program on motivation and physical performance responses. Based on the
findings mentioned earlier, the hypothesis is that a suitable home-based
exercise program will improve the motivation to training and physical
performance in this group.
Participants
Initially, nine
recreational young female adults (26.0 ± 4.7 years old), belonging to a futsal
team competing in regional championships, volunteered to participate in this
study. All players were quarantined since March 21st by n°7821
ordinance, in which the Guarapuava city, located on
Paraná, South of Brazil, determined the social isolation [9]. The criteria for
participants' inclusion were: being a member of the
recreational futsal team, being home-quarantined, and 18 years older. The
exclusion criteria were not complete at least 80% of sessions of the exercise
program. A total of five athletes took part in the final study. All procedures
had the approval of the local ethics committee (protocol number 4.042.783).
Informed consent was obtained from each participant before study commencement
by online form.
Study overview
This study is a
quasi-experimental (pre/post-test) with a longitudinal design, including a
convenience sample of a recreational futsal team. Before the study started,
participants reported no involvement in any exercise-program since they began
the quarantine period (the last training session was on March 15th). The
home-based exercise program and physical testing took place between April to
May, completing six weeks. In the first week (phase I), the participants were
informed regarding the study's aim and signed the online form consent; also,
they performed physical tests (e.g., long jump, abdominal and upper limb
resistance). During the following four weeks (phase II), participants engaged
in a home-exercise program (three weekly full-body resistances training
sessions) administered online by recorded video and live approach. In the sixth
week (phase III), participants performed the same physical tests before the
exercise program (Figure 1).

Home-based exercise program
The home-based
exercise program included three weekly sessions (Monday, Wednesday, and
Friday), characterized by full-body exercises with 30minutes duration each
session. The training session was preceded by a progressive warm-up (e.g., stationary
running and jumping jacks), followed by a circuit resistance training with nine
exercises in each set, ending with cool-down exercises (stretches). All
training sessions involved a circuit resistance training format with
alternation between upper body and lower body movements as well as core
exercises, included: 1) squat, 2) push-up (keen on the floor), 3) lunge, 4)
abdominal crunch, 5) high bridge, 6) burpee, 7) standing calf raises, 8)
triceps dips and 9) plank. Week one and two participants performed 15
repetitions of each exercise and 20min plank in 2 sets. Week three and four
participants performed three sets and were asked in exercises 1,3 e 4,
performed with 1kg or more (e.g., a bottle of water, food package).
The participant
had two options to perform the program: receive a video with all sessions
demonstrated by an evaluator or perform the session in real-time with the
evaluator and other participants (e.g., such a live approach). For those
participants who opted to receive the video, a full training session was
demonstrated by one evaluator. The video was sent in a team-group on cellphone
one day before each training session to participant performs any time during
the day established (e.g., on Sunday was send a video to Monday training-session,
and so on). For those who chose to execute the training as a live approach, the
evaluator sends a link with access to an online platform. The online class
started at 8 pm, as the training session before the quarantine.
During the
training program, an evaluator sent messages in both team-group and personally,
reinforcing participants to perform the exercises.
Perceptual measures
In each training
session, training motivation was assessed by a Likert scale ranging from 0 (not
motived at all) to 4 (extremely motivated). Participants were asked, "How
would you rate your motivation to train right now?". This approach has
been used before in sport-settings daily to analyze the motivation to train
[7,8].
The perception
of effort (RPE) was taken after each training session. RPE was assessed by the
Borg Rating of Perceived Exertion 6-20 Scale translated and validated to
Portuguese [10]. Participants answered: "how hard and strenuous was the
exercise session," according to the RPE scale ranges from 6 to 20, which 6
= no effort and 20 = maximal effort.
Both motivation
and RPE were answered by a google form link sent to their cellphone every
training session by the evaluator.
Physical performance
To verify the
impact of a home-based exercise program on physical performance, participants
performed one week before the exercise program, and after the last training
session, the following tests: long jump, abdominal and upper limb resistance
tests. An isometric, long jump test was performed with a one maximal bilateral
anterior jump with arm swing. Jump distance was measured from the starting line
to the point at which the feet contacted the ground on landing [11]. Abdominal
resistance was evaluated in the supine position, with arms crossed and keens
flexed, and a complete movement was required for one minute [12]. Upper limb
resistance was evaluated by push-up test; in the supine position, the
participants flex the elbows to approximately 90 degrees and extend them again,
with their knees on the floor. Only complete repetitions counted [13].
Participants experienced all tests two days before the evaluation. During all
tests, one evaluator was present remotely, online, to correct the movements, motivated,
and counted the repetitions.
Statistical analysis
Due to reduced
sample, descriptive statistics were opted to describe the motivation to
training and training perception of effort. Individually description was used
to report the physical tests pre-and post-exercise program.
The home-based
exercise program started with nine participants belonging to a recreation
female futsal team; however, four participants quit during the program.
Participants who performed 80% of the home-based exercise program (n = 5)
decreased their exercise frequency through the weeks. In the first week, the
participants carried out an amount of 15 sessions, the second week 14 session,
third week 13 session, and the fourth week, only five sessions. Demotivation
and unavailability to train were the reasons to drop the training sessions, as
reported for the participants. The RPE of the training session is present in
Figure 2 and training motivation in Figure 3.

Individual
descriptive data for pre and post physical tests (e.g., long jump, abdominal,
and push-up) are in Table I. All participants increased their results in all
physical tests.

The major
finding in the current study was that four weeks of home-based exercise program
during the quarantine due to the COVID-19 outbreak increased physical
performance in the recreational female futsal team, even with a decrease of
motivation and frequency of home-based exercise sessions. Moreover, it is also
important to highlight that four participants dropped their participation
during the exercise program. The study's results reinforce the benefits of a
home-based exercise program; however, the study highlights the necessity of
creating a protocol for home-based exercise programs focusing on promoting
participants' adherence, especially during the quarantine period.
The decrease in
training motivation and participants' drop during the exercise program needs to
be interpreted with attention and caution. Recent studies demonstrated that
young adult females are more sensitive to suffer from anxiety, depression, and
psychological stress during this COVID-19 quarantine than men and old adult
people [14-16]. These symptoms worsen as far as the quarantine lasts [17];
therefore, we speculate that the lack of adherence and the decrease of
motivation may be due to negative responses regarding the quarantine. Another
speculation is about the athlete's level. A study elsewhere that evaluated
women elite and non-elite athletes from different sports during a regular
training period demonstrated that elite athletes present a higher motivation to
train than non-elite athletes [8].
Maintain the
physical activity levels during the quarantine period is one of the most
significant challenges. Studies from Croatia coastal region [18] and Sicilia in
Italy [19], both conducted in March and April of 2020, demonstrated decreased
physical activity levels during the COVID-19 pandemic in adolescents and
adults, respectively. As discussed in the Italian study [19], the authors point
out that "practicing more physical activity is better than practicing less
of it, however doing at least some physical activity is better than doing
nothing."
In the present
study, a home-based exercise quarantine program proposed a full-body exercise
in the circuit format, realized three times per week. Recent recommendations
reinforce the 150 to 300 min of aerobic exercise and two strength exercises
sessions with moderate intensity per week [20]. Participants followed the
"moderate-intensity" recommendation in the current home-based
exercise program and some of the resistance exercise proposed previously
[20,21]. Nonetheless, the program did not reach the number of minutes
recommended.
Considering the
participants who took part in 80% of the exercise program, even with a decrease
of motivation, especially during week 4, they increased their performance on
physical tests (long jump, abdominal, and push-ups). Therefore, we highlight
the importance of home-based exercise for physical performance and,
consequently, health, even with less amount. Additionally, the delivery of a
supervised home-based exercise program is important to monitoring exercise
intensity, orientation for exercise execution, and monitoring the participant's
motivation.
Even though the
current study collaborates on a novel research topic, limitations need to point
out. The sample size, using only one recreational team, is the major
limitation. Moreover, a home-based exercise program restricted to three times a
week, with 30minutes duration, was not an ideal exercise program according to
exercise recommendations. Anyway, it is worth mentioning that the limitation of
resources to implement a robust home-based exercise program involving a large
sample and the lack of knowledge about a home-based exercise program to
recreational athletes during the quarantine should be considered when
interpreting the current findings.
In conclusion, the present results demonstrated that a
home-based exercise program during the quarantine due to COVID-19 effectively
increased a recreational female futsal team's physical performance. Moreover,
the quarantine period could contribute to a lack of adherence and decrease
training motivation. Based on the current study results, an organization of a
home-based exercise program should address both physiological and psychological
factors, especially during the quarantine period. Future studies with a large
sample from different sports and team levels (e.g., non-elite and amateur
female and male athletes) should investigate this topic to corroborate or
refute the present findings.
