Physical activity and verbal memory performance: Mediating effects of resting-state brain activity.

Verbal short-term and long-term memory are crucial neuropsychological functions involved in core cognitive abilities. They constitute vital components of subjective well-being and academic achievement. To date, there is limited research on the association between regular physical activity and memory abilities during young adulthood. The Individual Alpha Peak Frequency (IAPF) contributes to various cognitive abilities and also appears to be sensitive to physical activity. Consequently, the IAPF has the potential to underlie the association between physical activity and verbal memory. We examined the direct relation of physical activity and verbal memory, and the potential indirect relation via IAPF in young adults. Regular physical activity was assessed via accelerometry on seven consecutive days in 115 participants (N=115, 48% female) aged 18-35 years (M=24.1, SD=3.8). In addition, verbal memory performance was assessed using an immediate and delayed free-recall task. Brain activity during rest was recorded with EEG, and IAPF was extracted for mediation analyses. Path analysis revealed pronounced sex differences in the association between physical activity, IAPF, and verbal memory performance. Exclusively in female participants, higher vigorous physical activity levels were associated with better recall performance. In contrast, no association of physical activity and memory was found in male participants. However, being more physically active was related to a higher IAPF exclusively in male participants. Physical activity shows differential associations between IAPF and verbal memory in male and female participants. However, the lack of a mediating role of IAPF suggests that this neurophysiological marker cannot explain these specific associations in young adults.

Dissecting the causal relationship between moderate to vigorous physical activity levels and cognitive performance: a bidirectional two-sample Mendelian randomization study.

Recent studies increasingly suggest that moderate-to-vigorous physical activity (MVPA) impacts cognitive risk. However, the bidirectional nature of this relationship warrants further exploration. To address this, we employed a Mendelian randomization (MR) approach, analyzing two distinct samples. These analyses utilized published genome-wide association study (GWAS) summary statistics for MVPA (n = 377,234) and cognitive performance (n = 257,841). Our primary method was the inverse variance weighted (IVW) model with random effects, aiming to deduce potential causal links. Additionally, we employed supplementary methods, including MR Egger regression, Weighted median, Weighted mode, and Simple mode. For sensitivity analysis, tools like the MR Egger test, Cochran's Q, MR PRESSO, and leave-one-out (LOO) were utilized. Our findings indicate a decrease in cognitive risk with increased MVPA (Odds Ratio [OR] = 0.577, 95% Confidence Interval [CI]: 0.460-0.723, p = 1.930 × 10-6). Furthermore, enhanced cognitive levels corresponded to a reduced risk of inadequate MVPA (OR = 0.866, 95% CI: 0.839-0.895, p = 1.200 × 10-18). In summary, our study demonstrates that MVPA lowers cognitive risk, while poor cognitive health may impede participation in MVPA. Overall, these findings provide valuable insights for developing personalized prevention and intervention strategies in health and sports sciences.

Physical Activity Patterns Within Dementia Care Dyads.

Previous research has explored the physical activity habits of people with dementia and their family carers separately, with little consideration of how physical habits are associated within dyads. In this observational study, we sought to explore the relationship between people with dementia and their carers' physical activity, at a group level and at a dyadic level. Twenty-six participant dyads (persons with dementia and their carer spouses) were asked to wear an accelerometer for 30days continuously. Comparisons were made at a group level and a dyadic level. People with dementia did not participate in significantly more moderate to vigorous physical activity (M = 15.44min/day; SD = 14.40) compared with carers (M = 17.95min/day; SD = 17.01). Within dyads, there were moderately strong associations between daily moderate to vigorous physical activity (r = .48-.54), but not with overall activity levels (r = .24). Despite physical activity habits remaining relatively low within people with dementia and carers, respectively, moderate to vigorous physical activity levels appear to be correlated within dyads. Understanding mutual influence on physical activity levels within dyads is an important pathway to promote an active lifestyle.

Fizička aktivnost i kvalitet sna kod bolesnika lečenih hroničnim hemodijalizama

Introduction/Aim: Hemodialysis patients are often sedentary and experience a high prevalence of sleep disorders. In this study, we aimed to assess the level of physical activity and quality of sleep among patients on maintenance hemodialysis and assess the relationship between these issues. Material and Methods: Seventy-one hemodialysis patients filled in the International Physical Activity Questionnaire (IPAQ) and the Pittsburgh Sleep Quality Index (PSQI) to assess their level of physical activity and their quality of sleep, respectively. Basic demographic, clinical and treatment-related characteristics were obtained from an electronic medical data system, as well as the results of standard laboratory analyses. The results were analyzed with Student t-test, Pearson chi-square test, linear by linear association, and Spearman correlation. Results: Nearly half of the patients (46.5%) were poor sleepers with an overall PSQI of 5.7 ± 4.4. Older age was significantly associated with worse sleep quality (p=0.019). Patients reported low, moderate or vigorous levels of daily physical activity in 42.3%, 50.7% and 7% of cases, respectively. No statistically significant associations were noted between demographic characteristics, dialysis vintage, comorbidities and the level of physical activity. Distribution of good and poor sleepers was almost identical among patients with low and moderate physical activity (47% vs 53% and 50% vs 50% respectively), whereas patients with vigorous activity were mostly good sleepers (20% vs 80%), but the difference was not statistically significant (p=0.591). Conclusion: We observed no statistically significant association between the level of physical activity and quality of sleep in this cohort. Further research with a larger sample might additionally elucidate this issue.

Near infrared spectroscopy for the classification of vigor level of soybean seed

Near infrared spectroscopy for the classification of vigor level of soybean seed

Optical analysis of the physiological quality of Triticum aestivum L. seeds with two vigor levels treated with Thiamethoxam

Insecticide treatment shields plants from pests. The standard tests are the ones that are most frequently used. However, some results may be unreliable or insensitive. Optical techniques such as ultra-weak photon emission and Fourier transform infrared spectroscopy can aid standard tests. In this study, two samples of wheat seeds were subjected to the accelerated aging test, resulting in two vigor levels. Every sample was divided into two groups (control and treated). The treated groups received 150 mL of Thiamethoxam for each 100 kg of seeds. The results showed that the length of the aerial part was insensitive. However, the length of the primary root showed the treated group (73% of the germination) was statistically different. The total photon counts and temporal slope profile averages associated with the ultra-weak photon emission for the treated group (73%) showed a significant difference between the control groups (73% and 94% of germination). Principal component analysis revealed differences between groups of distinct seed vigor levels. Still, it did not show differences between the groups treated and untreated. By comparing the results, optical techniques can be used to assess seed physiological quality, particularly the vigor level.

Acute effects of virtual reality exercise bike games on psychophysiological outcomes in college North-African adolescents with cerebral palsy: A randomized clinical trial

Background Cerebral palsy (CP) is a neurological disorder that can affect motor skills and psychophysiological well-being. Virtual Reality Exercise (VRE) has been shown to improve cognitive and physical outcomes for patients with CP. Therefore, the aim of this study was to investigate the effects of VRE on attention, vigor, and decision-making abilities in adolescents with CP. Methods A randomized controlled trial was used. Fourteen Tunisian college adolescents (15.6 ± 0.7 years; diagnosed with CP) were randomly assigned to either the VRE group or the Traditional Exercise (TE) group. The VRE group engaged in 40 min exercise sessions using VRE bike games, while the TE group participated in TE sessions. Results Fourteen participants (42.9 % females) were included in this analysis The results showed that VRE had a significant positive impact on attention and vigor compared to TE. Participants in the VRE group demonstrated improved attention levels and reported higher levels of vigor following the exercise sessions. Conclusions The findings suggest that VRE is an effective intervention for improving attention and vigor abilities in adolescents with CP. Further research is needed to confirm these findings and to investigate the long-term effects of VRE. Registration Pan African Clinical Trial Registry (PACTR202308598603482; 31/08/2023).

The economic rationale for the provision of technical/vocational education (TVE) in colonial Ghana: Implications for practice

The paper examines the economic rationale for the provision of technical/ vocational education (TVE) in colonial Ghana. It further highlights some key lessons drawn from the study, particularly, in term of the Ghanaian contemporary search for a more pragmatic policy formulation for TVE. Data were retrieved from primary sources in the form of archival materials and some secondary sources as well some interview sessions with two personalities who were actively involved in the provision of TVE during the period. Chronological and thematic analysis of the data were utilized. The study revealed that the missionary bodies and the colonial administration vigorously promoted TVE largely because of economic reasons. It further argues that this level of vigor could not unfortunately keep pace with the developmental needs of the country due mainly to overriding interest in literary/grammar education, lack of entrepreneurial training for graduates of the TVE institutions and virtual non-existence of local industries to absorb these graduates.

Rootstock effects on leaf function and isotope composition in apple occurred on both scion grafted and ungrafted rootstocks under hydroponic conditions.

Rootstocks are used in modern apple production to increase productivity, abiotic and biotic stress tolerance, and fruit quality. While dwarfing for apple rootstocks has been well characterized, the physiological mechanisms controlling dwarfing have not. Previous research has reported rootstock effects on scion water relations. Root architecture and variability in soil moisture across rooting depths can also contribute to these differences among rootstocks in the field. To exclude these effects on rootstock behavior, scions were grafted onto four different rootstocks with varying effects on scion vigor (B.9, M.9, G.41 and G.890). Non-grafted rootstocks were also grown to examine whether the effects of rootstock occurred independently from scion grafting. Plants were grown in a greenhouse under near steady-state hydroponic conditions. Carbon (δ13C), oxygen (δ18O) and nitrogen (δ15N) isotope composition were evaluated and relationships with carbon assimilation, water relations, and shoot growth were tested. Rootstocks affected scion shoot growth, aligning with known levels of vigor for these four rootstocks, and were consistent between the two scion cultivars. Furthermore, changes in water relations influenced by rootstock genotype significantly affected leaf, stem, and root δ13C, δ18O, and δ15N. Lower δ13C and δ18O were inconsistently associated with rootstock genotypes with higher vigor in leaves, stems, and roots. G.41 had lower δ15N in roots, stems, and leaves in both grafted and ungrafted trees. The effects of rootstock on aboveground water relations were also similar for leaves of ungrafted rootstocks. This study provides further evidence that dwarfing for apple rootstocks is linked with physiological limitations to water delivery to the developing scion.

Maternal and neonatal factors affecting neonatal behaviour in West African Dwarf goats.

There is a paucity of information on neonatal behaviour of tropical livestock species despite its adaptive value. One hundred and ninety West African Dwarf (WAD) kids and their mothers were studied to establish the influence of neonatal and maternal factors on neonatal behaviour. Environmental temperatures and relative humidity (RH) at birth were also recorded. Single born kids and those dropped by older and multiparous mothers sucked earlier (p < 0.05). Vigour levels were higher (p < 0.05) in kids dropped by multiparous does and those whose grooming commenced earlier than those dropped by primiparous does and those with long latency to groom, respectively. Moderate negative correlations (p < 0.01) existed between duration of grooming and birthweight and duration of grooming and latency to groom. Similarly, strong and positive correlations (p < 0.01) existed between duration of grooming and neonatal vigour and time of first successful sucking and number of attempts at standing postpartum. Moderate positive correlations (p < 0.01) existed between time of first successful standing and number of attempts at standing postpartum, birthweight and vigour, rectal and ambient temperatures, latency to groom and birthweight, latency to groom and time of first successful sucking postpartum and number of attempts at sucking and time of first successful sucking postpartum. Strong negative correlations (p < 0.01) existed between RH and latency to groom (p < 0.01) and latency to groom and number of attempts at standing postpartum. Maternal care was higher in WAD goats during periods of higher RH and also in vulnerable and low birth weight kids.

Influence of the practice of physical exercise and healthy eating on the Vigour of university lectures

IntroductionVigour at work is characterized by high levels of energy and high desire to make an effort at work. This article is the result of a research carried out with university teachers in Spain whose main objective is to show what type and frequency of physical exercise and diet influence Vigour.MethodsThe sample consisted of 121 subjects, 62% of whom were women and 37.2% men. A questionnaire was administered to collect information on sociodemographic data, physical exercise habits, eating habits and Vigour at work. Cross-tabulations of the dimensions of Vigour with sex, age and type of contract offered were performed. Spearman correlations and Correspondence Analysis are also carried out to provide information on the intensity and type of relationships between the Vigour dimensions. Finally, the influence of the frequency of physical exercise and diet on Total Vigour is investigated.ResultsThe results show that the relationships between the dimensions are very strong (sig = 0.001). In addition, the practice of moderate-high intensity physical exercise and maintaining a good adherence to the Mediterranean Diet is related to high levels of Total Vigour (F = 7.955; sig = 0.006). As for the influence of the sociodemographic variables used, significant differences were only observed in the Physical Strength dimension for sex (X2 = 6.173; p = 0.046) and age (X2 = 9.449; p = 0.051) and, with respect to the type of contract, in Emotional Energy (X2 = 19.487; p &amp;lt; 0.001).Discusión and conclusionsThe main conclusions of our study show that practicing physical exercise of medium-high intensity four hours or more per week and a high adherence to the MD is more related to high Vigour levels than just eating well or just practicing exercise. And more studies are needed on the influence of sociodemographic variables on Vigour and its different dimensions.

Smoking, Physical Activity, and Hypertension Incidence Among Older Adults in Malang, Indonesia

Hypertension is a crucial health concern that requires attention, and it can be influenced by factors such as smoking and physical activity. According to a study conducted at Lawang Health Center, Malang, Indonesia, in 2020, 13.5% of the population in RW 05, Bedali Village, Malang, suffered from hypertension. It was one of the top three prevalent diseases in the village, especially among individuals aged over 69 years. The objective of this research was to examine the relationship between smoking, physical activity, and the occurrence of hypertension among older adults in RW 05, Bedali Village, Lawang, Malang. The study employed a case-control analytic observational method, involving 25 cases and 25 controls within the older adult age group (&gt;45 years). The participants consisted of 50 individuals, including 23 men and 27 women. Among the respondents, 23 were smokers, while 27 were non-smokers. Additionally, 25 respondents engaged in light physical activity, whereas 25 respondents had moderate to vigorous physical activity levels. The analysis indicated a significant correlation between smoking, physical activity, and the prevalence of hypertension among older adults in RW 05, Bedali Village, Lawang, Malang, with a p-value of 0.005 for each factor.

A low carbon balance triggers Microvine inflorescence abscission at high temperatures

IntroductionGlobal warming is a major threat to yield sustainability in most crops, including grapevine. Whether or not grapevine fruitfulness is impaired by an imbalance between carbon supply and demand caused by high temperatures was investigated in the present study.MethodsFive experiments were conducted on Microvine, a natural mutant of grapevine that is insensitive to gibberellins, presents with a dwarf stature, and has continuous flowering along the vegetative axes. The last property was used to infer temporal patterns of inflorescence development from their spatial distribution at harvest. Two sets of plants, characterized by low or high levels of initial shoot vigor, were grown under contrasting day and night temperatures: 22°C/12°C and 30°C/20°C.Results and discussionThe rate of leaf development of the main shoot was stable, regardless of the initial vigor and temperature treatment. In contrast, the warm temperatures delayed the timing of flowering for low-vigor plants or the onset of ripening for high-vigor plants. Fruitfulness was impaired by high temperatures as a result of the abscission of young inflorescences (before the flowering stage). From a careful spatiotemporal analysis of cluster abscission, we concluded that inflorescence drop under elevated temperatures was triggered by the increase in plant carbon demand due to the oldest clusters starting to unload sugars. Elevated temperatures may have also lowered the carbohydrate supply in the zone of inflorescence abscission due to the higher leaf respiration while all organ growth demand was maintained. Interestingly, inflorescence abscission occurred earlier when whole-plant vigor was low and was followed by a recovery period, in spite of a lower non-structural sugar status than in high-vigor plants. Taken together, our results suggest that inflorescence abscission is linked to the variations of the carbon pool induced by changes in temperature and not to its absolute value. Our study, therefore, provides new hypotheses about the impacts of warm temperatures on the regulation of temperature-induced reproductive failure in grapevine.

The Influence of Marriage and Cohabitation on Physical Activity Among Middle-Aged and Older People.

Using data from a nationally representative longitudinal study, Midlife in the United States (waves 1-3; N = 1113; aged 49-93), this study investigated whether partnered living status (partnered vs. non-partnered) and partnered living quality (support/strain from partner, partner disagreements) were associated with physical activity in middle-aged/older adults. Regressions were performed to test the effect of change or stability in partnered living status across three waves and relationship quality on the frequency of moderate and vigorous physical activity at Wave 3. Subjects who changed from non-partnered to partnered living had the highest moderate and vigorous physical activity levels. Partner support was positively associated with moderate physical activity (β = .50, p < .01), and partner disagreement was negatively associated with vigorous physical activity (β = -.27, p < .01). Results suggest that partnered living status and quality can influence physical activity among the aging population. Physical activity interventions among older adults may benefit from including social support as a key component.

A Pilot Study of Exercise Training for Children and Adolescents With Inflammatory Bowel Disease: An Evaluation of Feasibility, Safety, Satisfaction, and Efficacy.

Children with inflammatory bowel disease (IBD) experience extraintestinal side effects including altered body composition, impaired muscle strength, and aerobic capacity. Exercise training may remedy these issues. To assess the feasibility, safety, participant satisfaction, and efficacy of a training program for youth with IBD. Children with IBD completed 16weeks of training (2 supervised + 1 home sessions per week). Feasibility was assessed by tracking recruitment, adherence, and compliance rates. Safety was assessed by tracking symptoms and adverse events. Posttraining interviews gauged satisfaction. Circulating inflammatory markers, body composition, muscle strength, aerobic fitness, and habitual physical activity were measured at baseline, midtraining (8wk), and posttraining. Eleven youth were recruited and 10 completed the study. Participants adhered to 28 (1) of 32 prescribed supervised sessions and 8 (4) of 16 prescribed home sessions. There were no adverse events, and overall feedback on training was positive. Posttraining, we observed an increase in lean mass (+2.4 [1.1]kg), bone density (+0.0124 [0.015] g·cm-2), aerobic fitness (+2.8 [5.7] mL·kgLM-1·min-1), and vigorous physical activity levels (+13.09 [8.95]min·h-1) but no change in inflammation or muscle strength. Supervised exercise training is feasible, safe, and effective for youth with IBD and should be encouraged.

PEP-flute selfcare in epidemic respiratory infectious diseases – high societal impact at low cost?

Abstract Background The COVID-19 pandemic has led to worldwide increases in mortality and disrupted healthcare systems. The necessary countermeasures have adversely affected our lives, both mentally and economically. Home-based interventions to help individuals with early COVID-19 overcome the disease with fewer symptoms are needed. This study explored if self-care using positive expiratory pressure (PEP) as airway clearance is effective in reducing respiratory symptoms and, thus hypothetically prevent COVID-19 associated pneumonia. Methods This open-label, randomized trial (ClinicalTrials.gov:NCT04530435) recruited community dwelling adults from Capital Region and Region Zealand in Denmark from 6 Oct 2020 to 26 Feb 2021. Eligible participants (verified SARS-CoV-2 infection, COVID-19 symptoms, and able to perform self-care) were randomized to usual care or to PEP-flute self-care (PEP thrice daily) as an add-on to usual care. PEP-flutes were delivered by express mail and instructions given by video-links. The primary outcome was a change (analyzed by repeated measures mixed linear models) in self-reported symptom severity from baseline to day 30, as assessed by the COPD (chronic obstructive pulmonary disease) assessment test (CAT). Another outcome was the perceived effect of PEP-selfcare. Results The PEP self-care group (n = 190) had significantly lower symptom severity (group difference -1.2 points (95% confidence interval -2.1 to -0.2; p = 0.017)) at day 30 compared to the usual care group (n = 188). The PEP self-care group reported less chest tightness, less dyspnea, more vigor, and higher level of daily activity. When asked, “How do you describe the PEP-flute effect?”, 30% (n = 56) from the PEP group reported PEP-use to provoke coughing of phlegm. No serious adverse events were reported. Conclusions In early COVID-19, PEP-flute self-care was effective in reducing respiratory symptom severity among community dwelling adults and may have a future societal impact at a low cost. Key messages • We advocate for more research in self-care interventions to confirm if campaigns and handouts of PEP-flutes to mobilize the citizens’ selfcare are suitable public health responses to the next pandemic. • More research is needed to establish efficacy of non-drug interventions like PEP-selfcare for airway clearance to prevent pneumonia.

Proteomic Analysis of the Effect of Accelerated Ageing on Allium mongolicum Seeds

Seed propagation is the most commonly used method for producing Allium mongolicum seeds. However, as storage time increases, the seeds may suffer from ageing to varying degrees. This study aims to investigate the proteome expression of A. mongolicum seeds with different levels of vigor. The findings of this study will provide evidence of protein expression levels that reveal the mechanism behind the ageing of A. mongolicum seeds. An integrated approach of tandem mass tag (TMT) labeling in conjunction with liquid chromatography–mass spectrometry (LC-MS/MS) was used to capture the differential protein expression profiles of A. mongolicum seeds under unaged (Control), lightly aged (LA) and severely aged (SA). In total, 4336 proteins were identified, of which 4318 were quantifiable. After accelerated ageing, 291 differentially expressed proteins (DEPs) were identified. Compared with Control, 36 DEPs (16 up-regulated and 20 down-regulated) were found in LA; and 139 DEPs (64 up-regulated and 75 down-regulated) in SA. Compared with LA, 116 DEPs (51 up-regulated and 65 down-regulated) were found in SA. A number of candidate proteins associated with seed ageing were screened, including ATP-dependent RNA helicase-like protein DB10 (Unigene0060546), β-D-glucan exohydolase (Unigene0008772), Histone H1.2 partial (Unigene0049278), defensin Ec-AMP-D2 (Unigene0042879), NAD(P)H dehydrogenase (quinone) FQR1 (Unigene0047137), glutathione S-transferase (Unigene0000863), oleosin S1-2 (Unigene0011542), probable inactive purple acid phosphatase 2 (Unigene0010352), glutathione S-transferase U8-like (Unigene0006910), and glutathione S-transferase U17-like (Unigene0051938). Additionally, this study was the first to determine the proteome of A. mongolicum seeds. These data provided references for further study of seed ageing mechanism of A. mongolicum.

Noninvasive measurement of blood calcium concentration using electrocardiography in peripartum Jersey cows.

We previously developed a noninvasive method for measuring blood calcium concentration (Ca) in Holstein cows on site using electrocardiographic (ECG) variables and calving number, based on a high positive correlation between Ca. Jersey cows easily develop peripartum hypocalcemia compared with other dairy cows. The early detection and treatment of hypocalcemia are particularly important for Jersey cows because delayed treatment can result in various complications. In this study, to establish a simple, noninvasive, on-site diagnosis of hypocalcemia in perinatal Jersey cows, we attempted to create an equation for estimating Ca using ECG waveforms. Overall, 112 Jersey cows 0-2 days postpartum were used. The ECG findings of these cows were measured using the base-apex lead for 30 s and the corrected ST interval (STc = ST peak interval/SS peak interval0.5) was calculated. Simultaneously, blood was collected from the tail vein, and the serum total Ca (tCa) and serum ionized Ca (iCa) were measured. Several items considered related to Ca were investigated. A strong positive correlation was observed between the tCa and iCa (r = 0.96). A positive correlation was observed between the tCa and STc-1 (r = 0.83). Furthermore, significant correlations were observed between skin temperature, calving number, vigor level, rumen movement, and auricle temperature (p < 0.05). Of these, multiple regression analysis was performed to calculate the tCa estimation formula with the STc and calving number (categorized into primipara, second parity, and third or more parity) as explanatory variables and the tCa as the objective variable (r = 0.85, p < 0.01). Of 15 postpartum Jersey cows, the estimation formula could mostly distinguish between cows with hypocalcemia, those with subclinical hypocalcemia, and normal cows. Blood Ca in peripartum Jersey cows can be noninvasively estimated using ECG variables and calving number.

Type of recess and its influence on girls physical activity levels

The purpose in this study is to describe the physical activity levels (PA) in primary school female students during four different types of recess: free, with sports equipment, with organized games and with music. Sample consisted of 20 girls (10.6 ± 0.70 mean age) from a Primary Education School in Region of Murcia (Spain). The data collection ocurred during 32 recesses. 8 sessions of each type of recess were observed and analyzed with the iSOPARC app, which structures the activity in three levels: sedentary, walking and vigorous. Results show medium-low levels of PA during breaks, being the free type the ones that reach the highest sedentary level values (39.79 ± 5.38%) while the organized ones obtain the lowest sedentary value (6.89 ± 2.56%). Regarding the vigorous level, the breaks in which music was used are the ones with the highest percentage (51.36 ± 12.55%). After applying the Mann Whitney U statistic, it is shown how the type of recess exerted a significant influence on the results (p = 0.000) in all cases. Conclusions. The recesses in which music is used, activities and games were planned and sports equipment are used achieve higher PA values at a vigorous level and less sedentary lifestyle. Keywords: physical education, MVPA, physical activity, recess.

Análise da associação entre níveis de fadiga por compaixão e engajamento no trabalho com a COVID-19 em profissionais de enfermagem

Abstract This article examines the association between levels of compassion fatigue and work engagement with COVID-19 in nursing professionals. A longitudinal, before-and-after study was conducted with nursing professionals working in the frontline in the pre-pandemic and pandemic periods. Our study applied the Brazilian versions of the Professional Quality of Life Scale and the Utrecht Work Engagement Scale. High levels of compassion satisfaction (≥43.0), low levels of burnout (&lt;23.0) and secondary traumatic stress (&lt;23.0), as well as high levels of vigor (≥4.0 and ≤4.99), absorption (≥4.0 and ≤4.99), and overall score (≥4.0 and ≤4.99) were observed. Moderate, negative, and significant correlations of burnout with vigor (r: -0.505; p-value: &lt;0.001), in the pre-pandemic period; and with overall score, in the pre-pandemic (r: -0.543; p-value: &lt;0.001) and pandemic periods (r: -0.458; p-value: &lt;0.001), were also observed. No changes in levels of work engagement were found. Professionals with compassion fatigue showed decreased vigor, absorption, and overall score, rated as medium in the pandemic period (≥2.0 and ≤3.99), and an increased dedication, which was low (≥1.0 and ≤1.99) in the pre-pandemic period. It was concluded that there is no harmful association between compassion fatigue and work engagement with COVID-19 in nursing professionals.
