The doubly labeled water method is a gold-standard method for the measurement of total energy expenditure in daily life. We aimed to identify the relationship between measured aerobic capacity and total energy expenditure, activity energy expenditure, or physical activity level using the doubly labeled water method in adults of advanced old age. A total of 12 physically independent older adults (10 men and 2 women), aged 81–94 years, participated in this study. The aerobic capacity was evaluated according to the lactate threshold. Total energy expenditure under free-living conditions was assessed using the doubly labeled water method, and self-reported physical activity was obtained using the Japanese version of the International Physical Activity Questionnaire. The lactate threshold was significantly positively correlated with total energy expenditure, activity energy expenditure, and physical activity level after adjusting for age and sex. We found that the aerobic capacity of the lactate threshold was positively and independently correlated with total energy expenditure, activity energy expenditure, or physical activity level. The present results suggest that maintaining aerobic capacity is an important factor in preventing frailty, although further research is required.

This study investigates strategies to increase physical activity levels among kindergarten children to meet the guidelines setby the World Health Organization. A systematic review was conducted, analyzing 19 studies identified through comprehensive searches of major databases. The review aimed to identify elements and equipment that should be incorporated into outdoor spaces to promote moderate and intense levels of physical activity. Additionally, it aimed to assess whether combining structured activities with free play contributes to increased levels of motor activity. The results of the review were as follows: fixed equipment, mobile equipment, open spaces and structured motor pathways have positive effects on moderate and intense physical activity levels; the combination of structured activities and free play also has positive effects on both physical activity levels and the improvement of certain motor skills. Furthermore, it was found that garden size and paving designs do not improve physical activity levels, while sandpits have a negative effect on them. This was followed by the design of the outdoor space. It included appropriately chosen equipment and materials to raise physical activity levels, without neglecting the important role of symbolic play in this age group. Collaboration and shared design with other professionals such as a playground designer and an architect was essential. This made it possible to produce a graphic design and a final rendering of the project.

Background and aims: The causes of relapses of ulcerative colitis (UC) are unknown. Dietary factors have been implicated in the pathogenesis of UC. The aim of this study was to determine which dietary factors are associated with an increased risk of relapse of UC. Methods: A prospective cohort study was performed with UC patients in remission, recruited from two district general hospitals, who were followed for one year to determine the effect of habitual diet on relapse. Relapse was defined using a validated disease activity index. Nutrient intake was assessed using a food frequency questionnaire and categorised into tertiles. Adjusted odds ratios for relapse were determined using multivariate logistic regression, controlling for non-dietary factors. Results: A total of 191 patients were recruited and 96% completed the study. Fifty two per cent of patients relapsed. Consumption of meat (odds ratio (OR) 3.2 (95% confidence intervals (CI) 1.3–7.8)), particularly red and processed meat (OR 5.19 (95% CI 2.1–12.9)), protein (OR 3.00 (95% CI 1.25–7.19)), and alcohol (OR 2.71 (95% CI 1.1–6.67)) in the top tertile of intake increased the likelihood of relapse compared with the bottom tertile of intake. High sulphur (OR 2.76 (95% CI 1.19–6.4)) or sulphate (OR 2.6 (95% CI 1.08–6.3)) intakes were also associated with relapse and may offer an explanation for the observed increased likelihood of relapse. Conclusions: Potentially modifiable dietary factors, such as a high meat or alcoholic beverage intake, have been identified that are associated with an increased likelihood of relapse for UC patients. Further studies are needed to determine if it is the sulphur compounds within these foods that mediates the likelihood of relapse and if reducing their intake would reduce relapse frequency.

Background and aim: Physical activity (PA) can modulate the immune response, but its impact on infectious disease severity is unknown. We assess if the PA level impacts the severity of COVID-19. Methods: Prospective, cohort study for adults hospitalized due to COVID-19, who filled out the International Physical Activity Questionnaire (IPAQ). Disease severity was expressed as death, transfer to intensive care unit (ICU), oxygen therapy (OxTh), hospitalization length, complications, C-reactive protein, and procalcitonin level. Results: Out of 326 individuals, 131 (57; 43.51% women) were analyzed: age: median—70; range: 20–95; BMI: mean—27.18 kg/m²; and SD: ±4.77. During hospitalization: 117 (83.31%) individuals recovered, nine (6.87%) were transferred to ICU, five (3.82%) died, and 83 (63.36%) needed OxTh. The median for the hospital stay was 11 (range: 3–49) for discharged patients, and mean hospitalization length was 14 (SD: ±5.8312) for deaths and 14.22 days (SD: ±6.92) for ICU-transferred patients. The median for MET-min/week was 660 (range: 0–19,200). Sufficient or high PA was found in recovered patients but insufficient PA was observed in dead or ICU-transferred patients (p = 0.03). The individuals with poor PA had a higher risk of death (HR = 2.63; ±95%CI 0.58–11.93; p = 0.037). OxTh was used more often in the less active individuals (p = 0.03). The principal component analysis confirmed a relationship between insufficient PA and an unfavorable course of the disease. Conclusion: A higher level of PA is associated with a milder course of COVID-19.

Adequate energy intake is essential for the healthy development of children, and the estimated energy requirement of children is determined by total daily energy expenditure (TDEE) and energy deposition for growth. A previous study in Japanese tweens indicated that TDEE could be estimated by fat-free mass (FFM) and step count. The aims of this study were to measure TDEE in Japanese preschool children and to confirm whether TDEE can be estimated by FFM and step count in preschool children. Twenty-one children aged 4–6 years old (11 girls and 10 boys; age, 5.1 (0.9) years; height, 107.2 (6.6) cm; weight, 17.5 (1.7) kg; BMI, 15.3 (1.3); mean (SD)) participated in this study. FFM and 7-day TDEE were obtained by doubly labeled water (DLW). Participants wore accelerometers during the DLW measurement period. No significant differences were observed in age-adjusted height, weight, BMI, FFM (13.0 (1.5) kg), or TDEE (1300 (174) kcal/day) between girls and boys. Girls had significantly higher percent fat and a lower daily step count than boys. Stepwise regression analysis revealed that FFM and step count were significant predictors of TDEE; TDEE (kcal/day) = 85.0 × FFM (kg) + 0.0135 × step count (steps/day). This accounted for 74% of TDEE variance. The current study confirmed that FFM and step count are major determinants of TDEE in Japanese preschool children as well as adolescents, although further research is needed to obtain precise equations.

This study aimed at assessing the physical activity level, heart rate and the salivary cortisol level of football society players. The sample consisted of 19 male masters football players with an average age of 56.7 ± 3.9 years. The long form of the International Physical Activity Questionnaire (IPAQ) and Polar® heart rate monitors were used as instruments, in addition to Salivette® tubes to measure salivary cortisol. Data analysis was performed by using the repeated measures Analysis of Variance (ANOVA) with Bonferroni post hoc test, and Spearman’s Rank Correlation Coefficient. The results showed that the salivary cortisol concentration indicated an index of 1.97 ng/ml at the beginning of the match; 40 minutes after that these values increased to 8.00 ng/ml, and 60 minutes after the match had started they reached 8.40 ng/ml. Considering the post-match moment, a moderate and positive correlation between the salivary cortisol concentration and heart rate (average and maximum) was seen. In conclusion, the physical effort expended during football Society practice needs to be monitored due to the high heart rate and high increase in the salivary cortisol concentration of this age group.

Millions worldwide suffer from long COVID, which affects daily life and impairs multiple organs. Younger adults report symptoms more frequently than older adults. Since physical activity enhances overall health, this study examines whether regular exercise reduces long COVID severity in college students. This cross-sectional retrospective study surveyed 309 teacher-training college students about their long COVID symptoms and physical activity levels. Participants were categorized based on activity levels, and symptom differences were analyzed. Among respondents, 44 (14.4%) reported long COVID symptoms, with fatigue being the most common (13.3%). Students engaging in regular, intense physical activity did not experience fewer symptoms than less active students (1.83 ± 0.85; 1.75 ± 0.89, p = 0.376). However, physical education students reported fewer symptoms than students in other programs (6.7% vs. 17.4%). Greater self-reported participation in physical activity was not associated with less reported long COVID symptoms among college-aged students; however, students enrolled in physical education programs—who integrate physical activity into their daily routines as part of their academic curriculum—reported fewer symptoms, suggesting that sustained, structured physical activity may contribute to reduced symptom burden. Further research is needed to explore this relationship.

BackgroundPrevalence and consequences of obesity and sedentary lifestyle are well-documented public health concerns for youth in the United State of America (USA) that disproportionally affect children from low income and minority families.ObjectiveThis mixed-method study focused on estimating levels of physical activity and sedentary behavior and prevalence of overweight and obesity among the child members served in one Boys & Girls Club in the Midwest USA. We aimed to better understand opportunities for improving children’s engagement in physical activity through focus groups with members, staff, and parents/caregivers of members.MethodSocial cognitive learning theory, the ecological model of health behavior, and community based participatory research principles provided the study framework. Members completed assessments of physical activity, sedentary activity, height, and weight. Focus groups with members, staff, and parents/caregivers identified barriers, facilitators, and opportunities for promoting physical activity.ResultsNearly 50% of members were overweight or obese. Most (87%) participants reported at least 60 min physical activity every day across the 3-day recall. Fewer than half (41%) reported 2 h or less of sedentary screen time every day across the 3 day recall. Focus group themes identified opportunities for addressing needs associated with health disparities in physical activity and pediatric obesity.ConclusionsFindings suggest stakeholder interest in physical activity promotion through afterschool programs. We discuss study implications regarding needs specific to individuals from diverse, low-income households that may not be adequately addressed with existing empirically-supported treatments and opportunities to address health disparities in physical activity and pediatric obesity through afterschool programs.

The compulsory part of the individual life is physical activity. The physical activity is important for maintenance health capacity. Physical activity includes various kinds of components: physical activity during the leisure time (during the week days and weekend days), physical activity at home and in working place and physical activity during the transference from home to other place. Intensity of the physical activity could also be various from low to moderate and till high. Respondent of study groups were partly time students from Riga Medical College (RMC), n = 41, and from Riga Teacher Training and Education Management Academy (RTTEMA), n = 37. Respondents were students of both genders aged from 19 years till 53 years. We have provided the assessment of the principal anthropometric characteristics (height and body mass) as well the anthropometric indices (body mass index (BMI)) and physical activity level questionnaire for students. Analysis of the data of physical activity questionnaire revealed that the average physical activity for students from RMC corresponded to low level of physical activity. The respondents from RRTEMA have moderate level of physical activity.

ObjectiveTo examine the associations and interactive effects of physical activity and sleep quality on mental health among Indian college students.MethodA cross-sectional study was conducted among Indian college students. The sociodemographic data and body mass index were obtained from a convenience sample of 617 college students, age range from 18 to 30 years, including both genders (314 men, 51%). All participants completed three questionnaires: the Hospital Anxiety and Depression Scale, the International Physical Activity Questionnaire-Short Form, and the Pittsburgh Sleep Quality Index. Questionnaires were evaluated to ascertain the subjects’ mental health level, physical activity level, and sleep quality. Analyses were conducted with binary logistic regression models.ResultThe mean (± S.D.) anxiety and depression scores were 9.3 ± 4.4 and 7.4 ± 2.5 respectively, with anxiety and depression scores ranging from 0 to 20 and 0–17, respectively.The prevalence of anxiety (30%) was more than that of depression (18%). Out of the total participants, 51% reported having low physical activity levels, and 51% had poor sleep quality. Odds ratio calculations indicated that the participants physical activity levels (moderate and high) were significantly and inversely associated with scores for anxiety (OR = 0.16 and 0.96; p = 0.001) and for depression (OR = 0.11 and 0.96; p = 0.001).The poor sleep quality was significantly positively associated with anxiety (OR = 1.38) and depression OR = 1.58 (p = 0.001).ConclusionMental health problems are common among both male and female college students. Significant associations were found between physical activity levels and sleep quality with mental health.
