The impact of COVID-19 lockdown on physical activity and sedentary behaviour in secondary school teachers: a prospective cohort study

BackgroundMid-March 2020, Belgium went in lockdown to combat the COVID-19-pandemic. Having to provide school-based day care and adapt to online teaching, while all social, cultural and sports events and activities were cancelled, secondary school teachers’ physical activity (PA) and sedentary behaviour (SB) may have been affected considerably. This study investigates the impact of the first Belgian lockdown on PA and SB in Flemish secondary school teachers.MethodsThis prospective cohort study was conducted throughout the 2019–2020 school year. PA and SB measured in March/April 2020 were compared with a pre-lockdown measurement in January/February 2020. Other pre-lockdown measurements (September/October 2019 and November/December 2019) and one other during-lockdown measurement (May/June 2020) allowed us to control for confounding. Validated questionnaires were used to assess participants’ PA and SB. Generalized linear mixed models were applied in R.ResultsAmong 624 participants (77·2% females, 43·3 ± 10·3 years), increases were observed for total PA (+ 108 min/week; p = 0·047), moderate PA (+ 217 min/week; p = 0·001), domestic and garden PA (+ 308 min/week; p < 0·0001) and leisure-time PA (+ 131 min/week; p < 0·0001), whereas work-related PA (-289 min/week; p < 0·0001) and active transportation (-38 min/week; p =0·005) decreased. No differences were observed for walking (p = 1·0) and vigorous PA (p = 0·570). Increases were found for total SB (+ 972 min/week; p < 0·0001), work-related SB (+ 662 min/week; p < 0·0001) and leisure-time SB (+ 592 min/week; p = 0·0004), whereas transport-related SB (-290 min/week; p < 0·0001) decreased.ConclusionDuring the lockdown, we found in our sample that Flemish secondary school teachers showed an increase in SB that was 9 times as high as their PA increase. As a government, education network or school, it is crucial to sensitize, promote, and facilitate sufficient MVPA and/or walking, but likewise to discourage SB during pandemic-induced lockdowns.

Changes in physical activity and sleep following the COVID-19 pandemic on a university campus: Perception versus reality

It has been hypothesized that key lifestyle behaviors of physical activity and sleep worsened in response to the Coronavirus disease (COVID-19) pandemic. However, there have been inconsistencies in findings of changes in these key lifestyle behaviors across populations likely due to the wide variety of assessment methods. The purpose of the study was to compare physical activity and sleep before and after the COVID-19 pandemic using accelerometers and self-reported behaviors. A longitudinal follow-up was conducted on students, faculty, and staff at a university campus in the United States. In the periods before March 2020 (covering the academic years of 2018–2019 or 2019–2020) and again in April–June 2021, participants completed surveys to evaluate their physical activity and sleep behaviors and wore an accelerometer. A total of 44 participants completed the survey at both timepoints and 32 completed accelerometer assessment at both timepoints. Fifty-seven percent of participants reported a perceived decline in physical activity, while 30% reported a worsening in sleep. From self-reported data, overall physical activity did not change, but there was a decrease in active transport (p ​< ​0.001) and increase in domestic physical activity (p ​= ​0.012). Sleep quality decreased as evidenced by an increase in Pittsburgh Sleep Quality Index scores (p ​= ​0.045). There were no changes in accelerometer measured physical activity or sleep. There were no changes in physical or mental health. While perceptions of physical activity declined from prior to the COVID-19 pandemic, there were no changes in device-measured physical activity, and changes in self-reported physical activity differed by domain.

Associations of lifestyle with burnout risk and recovery need in Flemish secondary schoolteachers: a cross-sectional study

Teacher burnout and high recovery need are a topic of concern for educational institutions. This cross-sectional study assesses the association between lifestyle (including physical activity (PA), sedentary behavior (SB), dietary behavior and sleep), burnout risk and recovery need in 1878 secondary schoolteachers in Flanders. In September–October 2019, an online-questionnaire assessing burnout (i.e., emotional exhaustion, depersonalization, personal accomplishment), recovery need, PA-domains, SB-domains, dietary behavior (including fruit and vegetable intake and diet quality) and sleep during the week and the weekend was completed. Multiple linear regression models were applied. More emotional exhaustion was associated with more domestic and garden PA, work-related SB and sleep during the weekend, whereas higher scores of emotional exhaustion were associated with lower fruit intake, diet quality and less sleep during the week. More depersonalization was associated with more leisure-time PA and work-related SB and with lower fruit intake. Teachers showing more recovery need, showed more domestic and garden PA and work-related SB, but less leisure-time PA and sleep during the week. Future research should use longitudinal or experimental designs to get more insight into causality. Despite the low effect sizes, education networks and schools might benefit from promoting and facilitating a healthy lifestyle in secondary schoolteachers.

Relationship between physical activity and muscle mass loss among people aged 60 and above in 15 provinces of China in 2015

To analyze the relationship between physical activity and muscle mass loss among Chinese elderly aged 60 years and above in 15 provinces. Data was collected from 2015 China Nutritional Transition Cohort Study. Information on demographic characteristics and physical activity was investigated by questionnaire. Dietary intake was estimated from three consecutive 24-h recalls for each individual. Appendicular skeletal muscle mass(ASM) was assessed using the bioelectrical impedance analysis(BIA). Skeletal muscle mass(SMI) loss was diagnosed according Asian working group of sarcopenia(AWGS) 2019 recommendation(male: SMI &lt;7.0 kg/m~2, female: &lt;5.7 kg/m~2). A total of 4565 participants aged 60 years and above from 15 provinces in China with complete information were included in the final analysis. Different domains(occupational, domestic, travel and leisure), light physical activity(&lt;3.0 METs), moderate physical activity(3.0-5.9 METs) and vigorous physical activity(≥6.0 METs) of physical activity among elderly adults were evaluated. Logistic multilevel model was used to analyze the relationship between low muscle mass and different intensity of physical activity duration. Among all participants aged 60 years and above in 15 provinces of China in 2015, women&apos;s participation rate in domestic physical activity was 91.7%, which was higher than men&apos;s rate of 62.3%. However, men&apos;s participation rate in occupational, travel and leisure physical activity were higher than those of women. The participation rate, duration of light physical activity and moderate physical activity were higher in women than in men(light physical activity: female duration 11.0 h/week vs. male duration 3.5 h/week; female participation rate 89.9% vs. male participation rate 62.8%; moderate physical activity: female duration 7.0 h/week vs. male duration 4.7 h/week; female participation rate 90.6% vs. male participation rate 75.2%). The median vigorous physical activity was 0 h/week in both male and female group. The prevalence of muscle mass loss was 13.9% among subjects. The median weekly light physical activity and moderate physical activity in muscle mass loss group were 5.8 h and 4.7 h, which were lower than in non-muscle mass loss group(9.3 h and 6.0 h). The OR of muscle mass lass was 0.71(95%CI 0.42-0.98, P&lt;0.05) for the male with 3.5-6.9 hours of moderate physical activity per week, compared to moderate physical activity less than 3.5 h/week. And OR of the female was 0.67(95%CI 0.47-0.95, P&lt;0.05). The vast majority of physical activity in China among the elderly is domestic and light physical activity. Light physical activity and moderate physical activity duration increments in female and moderate physical activity duration increments in male were associated with decreased risk of muscle mass loss.

Work from home and the association with sedentary behaviors, leisure-time and domestic physical activity in the ELSA-Brasil study

BackgroundWork from home (WFH) can impact workers´ sedentary behaviors and levels of physical activity. The aim of this study was to estimate the association between WFH and workers´ sedentary behaviors, leisure-time and domestic physical activities during the COVID-19 pandemic and verify whether age and sex may act as effect modifiers.MethodsWe conducted a cross-sectional study of 2544 participants in the supplementary study on COVID-19 in the Longitudinal Study of Adult Health (ELSA-Brasil) from July 2020 to February 2021. We assessed screen time (≤ 8 h/day versus > 8 h/day), accumulated sitting time (≤ 8 h/day versus > 8 h/day) as sedentary behaviors on a typical day, and leisure-time (active versus inactive, according to World Health Organization recommendations) and domestic (low versus high, according to median) physical activity, using the International Physical Activity Questionnaire (IPAQ), before and during social distancing. Logistic regression models were used.ResultsParticipants that were working from home during social distancing showed increased odds of screen time and sitting time greater than 8 h/day (OR = 3.12; 95%CI: 2.32–4.20 and OR = 2.68; 95%CI: 2.02–3.56, respectively) and higher odds of high domestic physical activity (OR = 1.29; 95%CI: 0.99–1.67) when compared to those not working from home. There was no association between WFH and leisure-time physical activity (OR = 0.99, 95%CI: 0.75,1.31). Age was an effect modifier in the association between WFH and leisure-time physical activity and domestic activity. Older people working from home showed higher odds of physical inactivity (OR = 1.84, 95%CI: 1.07,3.16) and high domestic physical activity (OR = 1.92, 95%CI: 1.12,3.27) compared to older people not working from home.ConclusionWFH was associated with sedentary behavior > 8 h/day and high domestic physical activity. In the older people, WFH was associated with physical inactivity and high domestic physical activity. As sedentary behavior and physical inactivity are consistently negatively associated with health, it is important to discuss policies to manage WFH that allow pauses from physical activities and performance of hours of work within preestablished limits to reduce sedentary behavior. In addition, individuals working from home, especially the older people, should be encouraged to engage in leisure-time physical activity as a form of health promotion.

The relationship between physical activity and depressive symptoms is domain-specific, age-dependent, and non-linear: An analysis of the Brazilian national health survey

Although there is consistent evidence of the beneficial effects of leisure physical activity (PA) on mental health, the role of PA in the domestic, transport, and occupational domains is inconclusive. This study aimed to analyze the relationship between domain-specific PA and depressive symptoms and examine whether the association is moderated by age in a representative sample of the Brazilian population. Cross-sectional data of 89,923 (52.4% female) individuals aged ≥15 years were analyzed. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Physical activity (min/week) performed in different domains (domestic, transport, occupation, and leisure) was self-reported. Generalized additive models with penalized splines were used to explore associations. Lower leisure-time PA and higher levels of PA in the domestic, occupational, and transport domains at distinct PA thresholds were associated with higher depressive symptoms. Leisure PA, even at lower levels, was associated with lower depressive symptoms compared to no PA at all. The increase in depressive symptoms as a function of occupational PA was observed only at PA levels higher than 40 h/week. Although non-leisure PA levels were related to higher depressive symptoms among the total sample, higher domestic and transport PA levels were related to lower depressive symptoms among older adults. This study provides insights into the non-linearity and age-group dependence of the relationship between domain-specific PA and depressive symptoms in a middle-income country. The evidence suggests that care should be taken on recommending PA regardless of context or domain.

Occupational and domestic physical activity and diabetes risk in adults: Results from a long-term follow-up cohort.

Physical activity (PA) has been associated with decreased incidence of diabetes. However, few studies have evaluated the influence of occupational and domestic PA on the risk of diabetes with a long-term follow-up. We aimed to examine the association between occupational and domestic PA and the risk of diabetes in a long-term prospective cohort of Chinese adults. A total of 10,343 adults who were followed up in the China Health and Nutrition Survey from 1997 to 2015 were included in our analysis. Occupational and domestical PA were collected with detailed seven-day data and were converted into metabolic equivalents values. Total PA included occupational, domestic, transportation, and leisure time PA. Diabetes cases were identified by self-reported doctor/health professional diagnosis of diabetes, fasting blood glucose ≥7.0 mmol/L, and glycosylated hemoglobin (HbA1c) ≥6.5%. Cox proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI). During up to 18 years of follow-up (median 10 years), there were 575 diabetes cases documented. Occupational PA accounted for the majority of total PA (68%) in Chinese population, followed by domestic PA (25%). With adjustments for possible covariates, the highest quartiles of total PA (HR, 0.728 [95% CI, 0.570-0.929]) and occupational PA (HR, 0.765 [95% CI, 0.596-0.982]) were significantly associated with a lower risk of diabetes compared with lowest quartiles. The association between domestic PA and the risk of diabetes was insignificant (P >0.05). Higher levels of occupational PA were associated with a decreased risk of diabetes risk in the Chinese population. Domestic PA was not associated with the incidence of diabetes.

Physical Activity and Sedentary Behaviour with Retirement in Maltese Civil Servants: A Dialectical Mixed-Method Study.

(1) Background: Retirement is a life event that can influence physical activity (PA) and sedentary behaviour (SB) and can be used as an opportunity to promote positive lifestyle choices. The aims of this study were to (a) to identify changes in PA and SB resulting from retirement and (b) to explore predictors of any changes in PA and SB following retirement in Maltese civil servants. (2) Methods: a hybrid mixed-method (MM) study, using first quantitative followed by qualitative methods, of civil servants aged ≥60 years, who were followed during their retirement transition for two years. A proportion of the research participants in the MM study retired while the others remained employed. Questionnaires and semi-structured interviews were used to collect data. (3) Results: there were no changes in total PA and sitting behaviour with retirement in Maltese civil servants. People who retired carried out more domestic PA compared to when they were in employment, which resulted in more moderate-intensity PA behaviour. People perceived that their sitting time increased with retirement in the qualitative interviews, but this was not observed in the quantitative data. Past PA behaviour was an important predictor of future PA behaviour, but not for SB. (4) Conclusions: A change in PA occurs with the retirement transition. However, the uptake of exercise is a personal choice that is dependent on previous experience. Increasing SB is perceived as part of the retirement plan but is not necessarily seen in the measured quantitative data.

Components of a healthy diet and different types of physical activity and risk of atherothrombotic ischemic stroke: A prospective cohort study.

BackgroundDiet and physical activity (PA) are modifiable risk factors thought to influence the risk of ischemic stroke (IS). However, few studies have examined their effect on different subtypes of IS.AimTo examine components of overall diet quality and different types of PA in relation to the risk of atherothrombotic IS (aIS).Materials and methodsThe study population included 23,797 participants (mean age 58 years; 63% women) from the Malmö Diet and Cancer Study cohort. Participants were enrolled between 1991 and 1996 and followed until end of 2016 (median follow-up 21.5 years). Incident aIS events were identified using national registries (total cases 1,937). Measures of PA (total, leisure-time, occupational, and domestic) were assessed using a baseline questionnaire and dietary intakes were estimated using a modified diet history method. Overall diet quality was assessed using a diet quality index. Intake of key food groups and beverages associated with overall diet quality were investigated separately. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using multivariable Cox regression models adjusting for confounders.ResultsA high diet quality with high intake of fruit and vegetables, fish and shellfish and low intake of sugar-sweetened beverages and red and processed meat compared to a low diet quality was associated with lower risk of aIS (HR = 0.82, 95% CI = 0.69–0.97; p = 0.015). Leisure-time PA was associated with reduced risk of aIS (HR = 0.95 per SD increase in MET-hours/week, 95% CI = 0.91–0.99; p = 0.028) with null associations observed for total, occupational and domestic PA level. We observed no significant interaction between diet and PA on the risk of aIS. The standardized 20-year risk of aIS among subjects with low leisure-time PA and low diet quality was 8.1% compared to 6.1% among those with high leisure-time PA and high diet quality.ConclusionSeveral components of a healthy diet and being physically active may reduce the risk of aIS, however, the absolute risk reduction observed was modest. A high diet quality seemed to have a risk reducing effect regardless of level of PA suggesting that individuals with a sedentary lifestyle may still gain some positive health benefits through a healthy diet.

Potential Mediating Effects Of Social Support And Physical Activity On Cognitive Function And Mortality Risk

Low cognitive function has been shown to be an independent predictor of all-cause and cardiovascular disease (CVD)-related mortality. However, there is limited evidence examining the potential mediating effects of social support network size and physical activity on cognitive function and mortality risk. PURPOSE: To examine the potential mediating effects of social support network size and total physical activity volume (TPAV) on cognitive function and all-cause and CVD-related mortality risk in a large, nationally representative sample of U.S. older adults. METHODS: Study sample (N = 2,550) included older adult (≥ 60 years of age) participants in the 1999-2002 National Health and Nutrition Examination Survey. Quartiles of cognitive function were created using Digit Symbol Substitution Test scores. Social support network size was determined using the number of reported close friends. TPAV was determined from self-reported domestic physical activity, transportation physical activity, and leisure time physical activity. The total weekly METs were determined for all three physical activity domains and quartiles of TPAV were created. RESULTS: Cox proportional hazards regression analysis revealed an approximate 3-fold increase in all-cause and CVD-related mortality risk in participants in the lowest quartile of cognitive function, compared to the highest quartile of cognitive function (Hazards Ratio [HR] 2.89; 95% Confidence Interval [CI] 2.33-3.59) and (HR 2.67; 95% CI 1.54-4.64), respectively. These relationships are independent of social support network size and TPAV. Linear and non-linear inverse dose-response relationships were also revealed between cognitive function and increased all-cause and CVD-related mortality risk, respectively (P for trend for both P < 0.0001). CONCLUSION: In a large, nationally representative sample of U.S. older adults, low cognitive function was associated with increased all-cause and CVD-related mortality risk. However, in contrast to previous evidence, both relationships were independent of social support network size and TPAV.

The Association between Physical Activity and Cognitive Function: Data from the China Health and Nutrition Survey.

Background Decreased cognitive function is a common problem in the old adults, which has high risk of progression to Alzheimer's diseases (AD) and other dementias. This study was aimed at finding out the association between physical activity and cognitive function. Methods In total, 1514 participants with the age ≥ 55 years old registered in the China Health and Nutrition Survey (CHNS) database were selected in this study. The association between physical activity and cognitive function was analyzed via the generalized additive model. The association between the variables and the cognitive function score was expressed as β coefficient with 95% confidence intervals (CIs). Results After adjusting age, ethnicity, stratum, marital status, education, memory status, and memory changes, the cognitive function score was increased by 0.011 points for every 1-point increase in domestic score (β = 0.011, P = 0.043). Subgroup analysis indicated that in the female group, for every 1-point increase in the domestic score, the cognitive function score increased by 0.019 points (β = 0.019, P = 0.017). In people with good memory status, each 1-point increase in domestic score increased the cognitive function score of 0.020 points (β = 0.020, P = 0.017). Conclusions The decreased cognitive function was correlated with decreased domestic physical activity. The increased domestic physical activity was associated with an increased cognitive function in females and people with good memory status. The findings might offer a reference for deep understanding of the association between physical activity and cognitive function.

Trend in physical activity patterns of pregnant women living in Brazilian capitals.

ABSTRACTOBJECTIVES To describe the trend of physical activity (PhA) in four domains performed by pregnant women living in Brazilian capitals and the Federal District (FD) and to verify the association between sociodemographic factors and the practice of leisure-time physical activity between 2007 and 2017.METHODS Time trend study carried out with data from the Surveillance System of Risk Factors for chronic diseases by telephone survey (Vigitel). A total of 3,730 pregnant women were interviewed in the period, considering sociodemographic variables (age, macro-region, work, marital status, schooling, skin color) and physical activity in the four domains (leisure-time, work, commuting, domestic – yes/no). For pregnant women who performed leisure-time physical activity, its duration was inquired, expressed in the variable PhA ≥ 150 minutes/week (yes/no). The time trend was evaluated by variance-weighted linear regression (average annual variation was expressed in percentage points – pp) and the association of sociodemographic factors with leisure-time physical activity by Poisson regression, with prevalence ratio (PR) estimation.RESULTS The prevalence of pregnant women with 12 years of schooling or more increased in the analyzed period (+1.37 pp/year), as well as the prevalence of pregnant women with more than 35 years of age (+1.11 pp/year) and those who work (+0.75 pp/year). The prevalence of leisure-time physical activity by pregnant women increased from 29.3% in 2007 to 37.6% in 2017 (+1.37 pp/year), and of PhA ≥ 150min/week from 2.3% to 20.6% (+2.33 pp/year), respectively, and there was a reduction in domestic physical activities from 63.9% to 38.9% (-1.65 pp/year). The prevalence of leisure-time physical activity was higher among pregnant women with more than 12 years of schooling (PR = 2.22; 95%CI: 1.73–2.84) as compared to those with less than 8 years of age, and lower among black/brown/indigenous pregnant women, compared to white/yellow ones (PR = 0.87; 95%CI: 0.78–0.97). The prevalence of PhA ≥ 150min/week increased according to years of schooling and age.CONCLUSIONS The prevalence of leisure-time physical activity and its performance for ≥ 150 minutes/week increased in the analyzed period, and both were directly associated with greater schooling.

Domestic Physical Activity and New-Onset Hypertension: A Nationwide Cohort Study in China

BackgroundThe relation of domestic physical activity with hypertension remains uncertain. We aimed to evaluate the prospective relation of domestic physical activity and new-onset hypertension among Chinese males and females. MethodsA total of 9254 adults who were free of hypertension at baseline were enrolled from the China Health and Nutrition Survey. Data on domestic physical activity were obtained by using self-reported questionnaires, and calculated as metabolic equivalent task (MET)-hours/week. Metabolic equivalent task-hours/week may account for both intensity and time spent on activities. The study outcome was new-onset hypertension, defined as systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg or diagnosed by physician or under antihypertensive treatment during the follow-up. ResultsA total of 2892 participants developed hypertension during 81996 person-years of follow-up. Overall, there were reversed J-shaped associations between the domestic physical activity and new-onset hypertension in both males and females (both P values for nonlinearity < .001). Consistently, when domestic physical activity was assessed as categories (<10, 10 -< 20, 20 -< 30, 30 -< 40, 40 -< 50, 50 -< 60, 60 -<70, 70 -< 80, 80 -< 90, 90 -< 100, ≥100 MET-hours/week), compared with those with domestic physical activity < 10 MET-hours/week, the lower and similar risks of new-onset hypertension were found in participants with domestic physical activity 30 -< 90 MET-hours/week in both males and females. ConclusionsModerate domestic physical activity was associated with a lower risk of new-onset hypertension among both males and females.

Methods and Strategies for Reconditioning Motor Output and Postural Balance in Frail Older Subjects Prone to Falls.

In frail older subjects, the motor output of the antigravity muscles is fundamental in resisting falls. These muscles undergo accelerated involutions when they are inactive and the risk of falling increases during leisure and domestic physical activity. In order to reduce their risk of falling, frail older subjects limit their physical activities/exercises. The problem is that the less they exercise, the less they are able to exercise and the greater the risk in exercising. Hence, a vicious circle sets up and the antigravity muscles inevitably continue to deteriorate. This vicious circle must be broken by starting a reconditioning program based on developing the strength of antigravity muscles (especially lower-limb muscles). To begin with, for each increase in muscle strength, postural balance is improved. Once this increase reaches the threshold beyond which postural balance no longer improves, it seems appropriate to implement exercises aimed at concomitantly improving motor output and postural balance in order to counteract or even reverse the involution process of the postural balance system. Methods and strategies toward this end are proposed in this present communication. However, the transfer effects between strength increase and postural balance ability are not yet totally known and future research should evaluate the relationship between muscle strength and postural balance throughout rehabilitation programs (i.e., program follow-ups) in frail older subjects in order to advance knowledge of this relationship.

Occupational physical activity, mortality and CHD events in the Italian Longitudinal Study

PurposeSeveral recent studies have suggested a ‘physical activity paradox’ whereby leisure-time physical activity benefits health, but occupational physical activity is harmful. However, other studies imply that occupational physical activity is beneficial. Using data from a nationally representative Italian sample, we investigate if the context, or domain, of physical activity matters for mortality and coronary heart disease (CHD) events.MethodsAmong 40,220 men and women aged 40–55 at baseline, we used Cox models to compare associations of occupational, domestic and leisure-time physical activity with risk of mortality and CHD events over a follow-up period of up to 14 years. We accounted for sociodemographic factors, smoking, body mass index (BMI), physical and mental health, and educational qualifications.ResultsOccupational physical activity was not significantly associated with risk of mortality or CHD events for women, or with CHD events for men. In crude models, risk of mortality was higher for men in the highest occupational activity group, compared to the lowest (HR 1.26, 95% CI 1.01, 1.57). This attenuated with adjustment for health-related behaviours, health, and education (HR 1.03, 95% CI 0.77, 1.38). In crude models, leisure-time physical activity was significantly associated with decreased mortality and CHD risk only for men. Domestic physical activity was not associated with either outcome for either gender.ConclusionIn a large sample of middle-aged Italian workers, we found limited evidence of harmful or beneficial effects of occupational physical activity on mortality or CHD events. However, confidence intervals were wide, and results consistent with a range of effects in both directions.

Relationships between grit, physical activity, and academic success in university students: Domains of physical activity matter

ObjectiveTo examine the relationships between contexts of physical activity, grit, and GPA in a college population. Participants: 875 Undergraduate students from a large, southern university participated between October 2018 and March 2020. Methods: Participants completed an electronic survey evaluating physical activity and grit. The university provided official GPAs. Multiple linear regression models evaluated the correlations between grit, the different physical activity domains, and GPA. Results: Grit was positively associated with domestic physical activity, leisure time physical activity, and GPA. Consistency of interest had no associations with the domains of physical activity or GPA. Perseverance of effort was positively associated with walking, active transport physical activity, domestic physical activity, leisure physical activity, and GPA. Conclusion: Perseverance of effort is related to different domains of physical activity and GPA. Future studies should investigate if increasing leisure time physical activity causes increases in perseverance of effort.

PHYSICAL ACTIVITY OF STUDENTS AT HIGHER EDUCATIONAL INSTITUTIONS WITH KINESIOLOGY AND HEALTH MAJORS IN THE SETTING OF COVID-19 PANDEMIC

The purpose of this study was to discover the peculiarities of students’ physical activities that study at higher educational institutions with kinesiology and health majors in the setting of COVID-19 pandemic. In order to accomplish it, an online survey was conducted among a total of 236 students of Lviv State University of Physical Culture named after Ivan Boberskyj. With its help, we were able to determine both domestic and organized physical activity levels’ self-assessments of the sample group before and during the quarantine restrictions. The majority of the students evaluated their physical activity levels as “excellent” and “good”. No significant changes among the physical activity assessments were not tracked during the quarantine restrictions. We established that 59% of the study group had regularly visited gyms before the pandemic breakout and 12% of the students systematic did home exercises. The remainder of active students (26%) exercised seldom. Before the pandemic, only 3% of the participants had not engaged themselves into organized physical activities. We observed an overall studentship physical activity decrease in terms of instances and intensity during the quarantine limitations. The forms of physical activities were substantially changed. Thus, the students began to stroll more often, as well as train alone or with online-coaches. Cardio and muscle strengthening remained dominant among activities both before and after the quarantine. After the quarantine restriction weakening, half of the study group re-embarked on gym training. 28% of the students continued exercising the same way they did during the quarantine. 12% of the respondents exercised on their owns. 7% of the participants did not return to training. With the respect to the results of this study, we can infer that Ukrainian students prefer group exercises where they can interact with either coach or other participant of the training sessions, as well as modern technologies cannot fully fulfill their needs of physical activity.

У I групі встановлено: пряму кореляцію з вірусним навантаженням (r = 0,16, р = 0,02), позитивну кореляцію між психічним компонентом ЯЖ та тривалістю сну (r = 0,24, р = 0,06); зворотній зв'язок з фізичною побутовою активністю (r = -0,43, р = 0,0001), загальним показником ЯЖ (r = -0,16, p = 0,02), фізичним та психічним компонентами ЯЖ – r = -0,19, р = 0,03 та r = -0,37, р = 0,13 відповідно, рівнем CD4+ T-лімфоцитами та ВН (r = -0,25, р = 0,06). У II групі встановлено: пряму кореляцію між втомою та тривалістю сну r = 0.46, р = 0.22, ВН r = 0.24, р = 0.28; зворотна кореляція була між ступенем втоми та загальним показником ЯЖ r = -0.18, р = 0.03, фізичним компонентом ЯЖ r = -0.15, р = 0.02., рівнем CD4+ Т-лімфоцитів r = -0.27, р = 0.17, фізичною побутовою активністю r = -0.35, р = 0.005, ВН r = 0.53, р = 0.28.&#x0D; Висновки. Побутова фізична активність може зменшити втому у ЛЖВ. Тривалість сну позитивно впливає на досліджувані нами патерни здоров’я у ЛЖВ. Встановлено, що втома пов’язана з високим ВН, низькою ЯЖ та ІМТ. Виникає потреба у розробці математичної моделі оцінки втоми.

Depressive symptoms in older adults: the role of physical activity and social support.

ObjectiveTo evaluate the role of social support in the association between physical activity (PA) in its various domains and depressive symptoms in older adults.MethodsThis was a cross-sectional study involving 399 older adults seen at basic health units in the municipality of Recife, state of Pernambuco, northeastern Brazil. Linear regression was implemented using the forward method to assess the association between PA and its domains and depressive symptoms, as well as to test the possible moderating component of social support in this association.ResultsOf the total sample, 17.6% reported not practicing PA; 6.7% presented depressive symptoms, with a mean score of 1.59 points. A total of 18.6% of the older adults assessed reported not having social support. Older adults who did not practice total, transportation or domestic PA showed increased scores of depressive symptoms when compared to older adults who practiced PA in these domains. Older adults with social support also had fewer depressive symptoms. Practicing domestic, leisure and total PA, and/or having social support, decreased depressive symptoms in older adults. Having social support or practicing PA decreased depressive symptoms in older adults in a similar way.ConclusionsOlder adults with social support and who practiced PA, especially domestic and total PA, presented the lowest scores of depressive symptoms. The data showed the importance of providing elements to strengthen social support and PA practice in older adults living in poor communities as a strategy to prevent and reduce depressive symptoms.

The effect of self-management intervention program on the lifestyle of postmyocardial infarction patients.

BACKGROUND:Most patients with myocardial infarction (MI) suffer from one or more risk factors such as obesity and overweight, unhealthy diet, lack of physical activity (PA), and high blood pressure. Individual control of these risk factors by lifestyle modification raises the probability of survival in these patients; hence, we used a self-management intervention to assess its effect on the lifestyle of post-MI patients.MATERIALS AND METHODS:This quasi-experimental study was conducted on 92 hospitalized MI patients in Hamadan province in 2016. Convenience sampling method was used for selecting the participants. The patients were selected and assigned to experimental and control groups. The main parameters (diet, blood pressure, waist circumference, and body mass index [BMI]) were measured at the baseline and 8 weeks after discharge. Domestic PA was the only parameter measured 8 weeks after their discharge. A self-management intervention was adopted for the experimental group. The data were analyzed using paired and independent-sample t-tests with SPSS software version 16.RESULTS:The comparison of the scores obtained for diet, blood pressure, waist circumference, and BMI in post-MI patients revealed no statistically significant difference between the two groups at the beginning of the study (P > 0.05). Following the intervention, the experimental group had a significantly higher mean score for diet and domestic PA (walking program from 1st week to 8 weeks), compared to the control group (P < 0.001); however, the intervention had no significant effect on BMI, waist circumference, and systolic and diastolic pressure (P > 0.05).CONCLUSION:The findings indicated that the program had an impact on some risk factors. Therefore, it is recommended to use self-management support in MI patients during the discharge process to improve their lifestyle.
