Objective: To assess the impact of coronavirus on the physical activity levels before and during self-quarantine, and the effect of self-isolation on the total mood status of Iranian citizens during the covid-19 pandemic. 

Material and Methods: A national sample of 2359 middle-aged (M age=42.8±5.3 years, n=1183,50.1%, male; n=1148, 48.7% female) Iranian completed an online questionnaire that assessed changes in daily physical activity behavior and mood status from March 20th to April 20th, 2020. The questionnaire implemented to collect the total duration, intensity, and frequency of physical activity and their psychological mood condition via the BRUMS Mood Scale.

Results: There were significant differences between physical activity frequency, duration, and intensity before and during the coronavirus pandemic. There was no significant difference between the total mood conditions between the sex categories. The main key finding of the current study is that the total physical activity participation behavior of our middle-aged populations has decreased meaningfully.

Conclusion: The present study has provided important approaches that should be implemented to promote the engagement of middle-aged adults in physical activity. Therefore, based on scientific evidence, maintaining a regular physical activity routine regarding world health organization guidelines is a key strategy for physical health.


The novel coronavirus disease 2019 (COVID-19) was diagnosed in December 2019 in the city of Wuhan, China, and it has swept across the world (1). COVID-19 is an infectious disease caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was classified as a global pandemic by the World Health Organization (WHO) (2). This has led to initiate the closing of most non-essential business services and nationwide lockdowns in countries all over the world (3). In addition, people were requested to obey social distancing, which is described as maintaining a distance of at least 1 m between with other people, avoiding crowded places and non-essential gatherings of more than 10 people, and restricting to meet older people or those in poor health (4-6). Consequently, changes in national behavioral patterns and closings of usual day-to-day functioning have occurred. Therefore, COVID-19 pandemic has already built unique challenges all over the world in terms of economy, social interactions, and individual lifestyles that require further investigation (7).

This dramatic change in lifestyle is characterized by physical inactivity, and sedentary behavior that are related to poor physical and mental health as well as increased all-cause mortality risk (3, 8-10). In the context of the COVID-19 pandemic, unwitting consequences may be a reduction in habitual physical activity and an increase in sedentary lifestyle behavior, owing to self-isolation and quarantine conditions that have reduced opportunities to remain physically active (11). The coronavirus pandemic acts as a considerable challenge to human health, particularly to exposed elderly people. The death rate in the patients over 60 years old was higher than other age groups (12). The benefits of physical activity and exercise have been demonstrated over the lifespan, human body works better when consistently physically active (3, 8, 9). Physical activity is defined as any bodily movement performed by skeletal muscles that demand energy expenditure (9, 13). WHO recommends that adults aged 18-64yrs should do at least 150 minutes of moderate-intensity aerobic physical activity or at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate and vigorous intensity activity (14). Physical activity includes walking, dancing, gardening, hiking, sports, and cycling in the context of daily, family, and community activities (13) . Regular physical activity is a key health behavior from a public health perspective, as it has a remarkable impact on the level of cardiorespiratory and muscular fitness, as well as mental health, specifically reduced anxiety (15). Hence, remaining physically active during the COVID-19 pandemic seems to be vital for physical and mental health since it can improve wellbeing and mood levels by helping to reduce stress, anxiety and depression (16). In addition, physical activity is related to mood and previous research has shown that moderate exercise can improve mood or help maintaining it at high level. 30 minutes of moderate or 15 minutes of moderate-vigorous physical activity per day was associated with a lower probability of depression and anxiety among Brazilian adults during COVID-19 pandemic (17).

Therefore, the present study aimed to investigate the effects of COVID-19 pandemic on daily physical activity behavior and total mood disturbance in Iran.

Material and Methods

Design and participation

This study has been designed as a descriptive cross-sectional online survey questionnaire (Figure 1). In order to be involved in the study, participants had to be over the age of 35, and were recruited through snowball sampling. The online survey was delivered through social media such as Instagram as well as regular media communications including stories in national and local media. Furthermore, via WhatsApp and e-mails, it was shared with the personal contacts of the research group members and the university students. This study was conducted from March 20th to April 20th, 2020. This survey evaluated several self-reported domains of their behavior and emotions towards the confinement period of COVID-19. All subjects engaging in the online questionnaire gave their informed consent before participation and  they were informed that they could withdraw from the study at any time. This study received approval from the human research ethics board at the SSRI (IR.SSRC.REC.1399.070).

Subjects were selected by convenience sample method by constructing a group of people who volunteered to participate. A total of 2359 Iranian of different social, city, culture classes and levels of education completed the online form questionnaire over a period the 30 days during COVID-19 emergency (Table 1). 1183 men, 50.1% (43.1 ± 5.3 years old), and 1148 women, representing 48.7% (42.3 ± 5.3 years old) of the total sample were involved.

The online questionnaire included three groups of questions: a) questions regarding demographic and socioeconomic data, b) questions regarding physical activity level and c) questions regarding mood through the Brunel Mood Scale (BRUMS).

Physical activity behavior

Physical activity questionnaire developed based on the study of Aghababa et al (18). The questions allow estimation of physical activity variables by duration (min), frequency (time/week), and intensity (low/high) of physical activity before COVID-19 pandemic and in the last four weeks during pandemic. Exercise behavior before or during the pandemic was measured with the question “How often have you exercised?” This included purposefully undertaken walks, fitness training, workouts indoor, badminton outside, football, swimming, hiking. Answers were given by marking one of the responses: “never”, “once in a while”, “once a week”, “two days per week”, “three days per week”, “four days per week”, “five days per week” “six days per week”, or “every day”. Subjects were also asked about their exercise intensity whether their exercise sessions were of low, moderate, high or very high intensity (19). Further, subjects stated the duration of physical activity during work, transportation and leisure time. Subjects were required to state activities less than 10 minutes or more than 10 minutes. The reliability and validity of this tool have been confirmed by Cho (20).

Mood status

A modified 16-item Brunel Mood Scale (BRUMS) questionnaire (short version) was used to evaluate level of positive mood (4-item) and negative mood (12-item) states (21). All subjects were asked to “describe how you felt in the last few days (under COVID-19)?” It consists a 5 items Likert scale. The total mood score was calculated from the sum of the 12 negative mood items (Angry, Worn-out, Uncertain about things, Grouchy, Hopeless, Fatigued, Annoyed, Discouraged, Exhausted, Gloomy, Weary, and Furious) and four positive (Lively, Alert, Active, Vigorous) items with a total mood score range of 0 to 64. We have used the total mood states, positive mood and negative mood scores in our analysis as an aggregated index of total mood disturbance. The BRUMS questionnaire was used because of its high validity, feasibility and it is a reliable common psychometric tool to assess an individual’s mood (Cronbach’s alpha: 0.90)(22). Also, the BRUMS questionnaire has validity and reliability in Iran (23).

Statistical analysis

Statistical analysis was performed using SPSS version 25 (SPSS, v.25, Armonk, NY, USA) for all analyses and the level of significance was set a priori at alpha = 0.05. Demographic characteristics have split by sex and summarized using descriptive statistics [Number (N), Means (M), Percentage (%), and Standard Deviations (SD)]. Normality of the variables was determined through the Shapiro-Wilk test, and for variables that were not normally distributed, non-parametric test was used to compare physical activity and total mood states. Wilcoxon Signed-rank test was used to assess statistical difference in the prevalence of insufficient physical activity before and during COVID-19 pandemic. The measurement of effect size r is calculated as Z statistic divided by square root of the sample size “r = Z/(√N)”. The magnitude of the effect sizes was judged according to the following criteria: r = 0.10 – < 0.30 was considered a ‘small’ effect size; 0.30 – < 0.50 represented a ‘medium’ effect size; and ≥ 0.50 indicated a ‘large’ effect size and the range is between 0 to 1. Mann-Whitney-U non-parametric test was used to compare BRUMS scores between genders. Further, to assess possible correlations between total score for habitual physical activity behavior with total mood states domains during the COVID-19 pandemic, we used the Spearman’s rank correlation coefficient test.


Descriptive statistics for subject characteristics are provided in Table 2.

Summaries of physical activity behaviors before and during coronavirus are illustrated in Table 3. There was a significant difference between physical activity frequency (Z = -3.178, P < 0.001), physical activity duration (Z= -12.78, P < 0.001), and physical activity intensity (Z = -26.54, P < 0.001) before and during COVID-19 pandemic as shown in Table 4.

Note. The measurement of effect size r was calculated as a Z statistic divided by square root of the sample size “r = Z/(√N)”. The magnitude of the effect sizes was judged according to the following criteria: r = 0.10 – < 0.30 was considered a ‘small’ effect size; 0.30 – < 0.50 represented a ‘medium’ effect size; and ≥ 0.50 indicated a ‘large’ effect size and the range is between 0 to 1.

Also, it was found that subjects who felt obliged to strictly follow the quarantine rules and recommendations have increased their physical activity frequency (Before COVID-19, mean ± SD, 4.3 ± 2; During COVID-19, mean ± SD, 4.6 ± 3.0; Z = -2.768, P < 0.001, r = -0.08) compared to subjects who didn’t really care about the quarantine rules and recommendations (Before COVID-19, mean ± SD, 4.05 ± 2.7; During COVID-19, mean ± SD, 3.7 ± 3.2; Z = -0.763, P = 0.445, r = -0.07) during COVID-19 pandemic. Further, we found that, the subjects who completely followed the quarantine rules and guidelines had higher education levels (PhD, N = 103, 10.2%, Master, N = 322, 31.9%) than the subject who didn’t care about the government restrictions (PhD, N = 5, 5.2%, Master, N = 29, 30.2%). Additionally, as shown in Table 5, we analyzed the condition of total mood status, positive mood, and negative mood during the COVID-19 pandemic (Total mood status; Men, 41.8 ± 11.7, M ± SD; Female, 41.1 ± 12.3, M ± SD). The analysis of total mood status shows that there is no significant difference in total mood (U = 64, P = 0.68, two-tailed), positive mood (U = 63, P = 0.48, two-tailed), and negative mood (U = 64, P = 0.75, two-tailed) disturbance between men and female during COVID-19 pandemic.

Finally, Spearman’s correlation analysis showed a significant positive correlation between total mood states and physical activity duration (r = 0.09, P < 0.001), and total mood states with physical activity intensity (r = .09, P < 0.001) during COVID-19 pandemic. (Table 6.)


The COVID-19 pandemic and quarantine lead to increased sedentary behaviors, reducing regular physical activity, consequently, lead to an increased risk for physical and mental health conditions. Therefore, the limitations of access to gym and clubs (e.g., closure of indoor and outdoor sporting facilities) and side effect stress of coronavirus have reduced overall physical activity intensity and duration.

We found that subjects followed quarantine rules and government restriction guidelines had better physical activity levels compared to subjects who didn’t care about the COVID-19 rules and restrictions. The subjects who followed the rules had higher education levels, as well.

Total mood states, positive mood and negative mood profile scores of female subjects were lower than men during the COVID-19 pandemic. The present study demonstrated that there were significant positive correlations between total mood states with physical activity duration and physical activity intensity during COVID-19 pandemic. It implies that having a better total mood states score can directly drive the goal of improving daily physical activity behavior (2, 7). Our results demonstrated that physical activity behavior can be related to the psychological mood status. Previous research supported the opinion that people who engaged in physical activity are happier, have greater life satisfaction, and live longer than those who do not (24).

For a large number of individuals, exercising indoors without any equipment and limited space can still be challenging (25). Therefore, there should be other options to be more physically active during lockdown. For instance, doing housework, climbing stairs, yoga, Pilates and participating exercise sessions via digital platforms and social media (3). These kind of activities are friendly and easily accessible while they do not require any expensive equipment. Previous findings indicated that reduction of daily physical activity behavior is strongly related to worse psychological mood status (11, 25-29).

The findings indicate the necessity of regular physical activity guidelines during the lockdown periods. During the COVID-19 pandemic, middle-aged adults developed greater concerns about their physical and mental health profile. Therefore, promoting physical activity programs can be very helpful.

This study has several limitations. Because of the limited resources available and the rapid onset of the COVID-19 outbreak, the snowball sampling procedure was selected. Although our respondents were not nationwide representative of Iranian middle-aged adults, we tried to utilize the social platforms to ensure the diversity and demographic representativeness of participants. Secondly, we had no data related the total mood states before COIVID-19 pandemic to compare the total mood profile before and during the pandemic.


Quarantine in Iran caused a significant reduction in physical activity intensity and duration of middle-aged adult groups. Physical activity behaviors seem to offer protective advantages in total mood states and wellbeing.
