Impact of physical activity and lifestyle in pre-infection on the susceptibility and prognosis of infects with COVID-19

Abstract Background There are very few studies focusing on the relationship between COVID-19 and pre-infection lifestyle. In the absence of effective vaccines and special-effect medicines, it is very meaningful to actively respond to the disease pandemic by improving lifestyle habits. Methods This is a multicenter, retrospective cohort study enrolled 431 adult people including 228 normal people and 203 confirmed infects in Wubei, Henan and Shandong Provinces. Questionnaires were used to collect information on physical activity and lifestyle by competent doctors. The univariate logistic regression models and multiple regression models were used in risk factor analysis. Kruskal-Wallis H test were used to test the correlation. Results Lifestyle habits including exercise, smoking, sedentary behavior and physical activity intensity can significantly affect the probability of getting COVID-19 (P < 0.05). The MET (Metabolic Equivalent) intensity classification and sleep status are found to be the potential influencing factors of prognosis in both all infects and symptomatic patients. In all infects, taking the high MET intensity level as a reference, inpatient days would increase by 1.812 times (95% CI: 0.887–3.701) with no significance when the level is moderate (P > 0.05) and significantly increase by 6.674 times (95% CI: 1.613–27.613) when the level is low (P < 0.05). Kruskal-Wallis H test results showed moderate activity MET*min promoted shorter hospital stay (P < 0.05) mainly. Conclusions Sleep status and physical activity influenced the susceptibility and prognosis of COVID-19. Lack of sleep and low MET intensity level may prolong the hospital stay, which means a relatively slow recovery. This encourages the public to have moderate physical activity and adequate sleep to respond to the COVID-19 pandemic actively.

INTRODUÇÃO: A saúde reprodutora masculina pode ser influenciada devida à prática de atividade física, e com isso tem-se aumentado o número de estudos que analisam o efeito da atividade física na qualidade seminal. Descobertas apontam que mudanças significativas na qualidade do sêmen podem ocorrer com a prática de atividade física, que pode alterar sua qualidade de acordo com o tipo de atividade física, a intensidade e a duração. OBJETIVO: Neste contexto, o presente estudo realizou uma análise detalhada da literatura atual com o objetivo de verificar o efeito de diferentes atividades físicas sobre a saúde reprodutora masculina. MÉTODO: Trata-se de uma revisão sistemática feita nas bases de dados do PubMed. Utilizou-se os itens propostos pelo PRISMA para a busca, seleção e extração de dados. De acordo com o fluxograma proposto, 244 artigos foram identificados e, destes, 12 foram selecionados. RESULTADOS: Apoiada por fortes evidências clínicas, esta revisão sugere que a atividade física intensa pode provocar fortes alterações hormonais e prejudicar a qualidade seminal. Já a atividade física moderada parece ter um efeito neutro ou benéfico para a qualidade do sêmen. Além disso, o efeito da atividade física na qualidade do sêmen pode ser diferente de acordo com o tipo de atividade física. CONCLUSÃO: Frente às evidências, ainda existe falta de conclusões sólidas sobre esse assunto, devido ao fato de existir muita contradição entre os estudos existentes e da atividade física não ser facilmente quantificada. ABSTRACT. Effect of physical activity on seminal quality, BACKGROUND: Male reproductive health may be influenced by physical activity, and this has increased the number of studies that analyze the effect of physical activity on seminal quality. Findings indicate that significant changes in semen quality can occur due to the practice of physical activity, which can alter its quality according to the type of physical activity, intensity and duration. OBJECTIVE: In this context, the present study performed a detailed analysis of the current literature with the objective of verifying the effect of different physical activity on male reproductive health. METHODS: A systematic review performed on the PubMed databases. The items proposed by PRISMA were used for searching, selecting and extracting data. According to the proposed flowchart, 244 articles were indentified and, of these, 12 were selected. RESULTS: Supported by strong clinical evidence, this review shows that intense physical activity can cause strong hormonal changes and impair seminal quality. On the other hand, moderate physical activity seems to have a neutral or beneficial effect on semen quality. In addition, the effect of physical activity on semen quality may differ according to the type of physical activity. CONCLUSION: Faced with the evidence, there is still a lack of solid conclusions on this subject, due to the fact that there is a lot of contradiction between the existing studies and that physical activity can not be easily quantified.

The Individual

Background:Parks are important settings for physical activity (PA), but few studies have documented the actual behaviors of park users. The purpose of this study was to examine the individual and joint effects of various park user demographic characteristics on observed PA intensity levels.Methods:Four parks were observed using the System for Observing Play and Recreation in Communities. Observers recorded the age group, gender, race, and intensity level of all park users in 83 activity areas over two weekends at each park. Logistic regression examined whether male/White, female/White, and male/non-White users were more likely than female/non-White users to be observed engaging in moderate-to-vigorous PA (MVPA) rather than sedentary activity across 4 age groups.Results:In total, 8612 users were observed during the study. In the child age group, male/White users were significantly more likely to be observed in MVPA than female/non-White users. For teens, female/White and male/White users were less likely to engage in MVPA. For both adults and seniors, female/White and male/White users were more likely to be observed in MVPA.Conclusion:Observations revealed significant differences in intensity levels across gender, age, and race groups. Future interventions should emphasize park design that promotes increased MVPA among diverse groups.

The Impact

Background:Researchers have noted both the utility and limitations of using pedometers to measure physical activity (PA). While these unobtrusive devices are widely accepted for their ability to measure accumulated PA, they have been criticized for their inability to measure exercise intensity. However, recent steps-per-minute (SPM) research provides reasonably accurate measures of intensity allowing users to assess time spent at recommended PA levels. Therefore, the purpose of this study was to determine the SPM taken that are associated with moderate physical activity in 12- to 14-year-old youth.Methods:Ninety-three participants (49 boys and 44 girls; ages 12 to 14) walked on a treadmill for 3 minutes at each of 4 different speeds while wearing a pedometer and a heart rate monitor.Results:On average boys and girls reached their moderate activity intensity threshold at 122 SPM and 102 SPM, respectively. However, individual differences must be taken into account when determining appropriate SPM intensities for youth.Conclusions:The impact of individual differences underscores the need to address SPM for moderate intensity individually rather than with a single guideline for everyone at this age.

After School Program

The purpose of this study was to evaluate the influences of a structured after-school program on student physical activity for third- through fifth-grade students at five schools in southern Colorado. The study utilized a pretest–posttest intervention design in which six elementary schools in a low socioeconomic status school district in southern Colorado were recruited to implement a structured curriculum into their existing after-school physical activity program. Four observations at each school were taken approximately 6 weeks apart during the 2014–2015 academic year. Randomly selected students (n = 187) were measured for height and weight at each observation and wore accelerometers during after-school physical activity. Descriptive statistics and independent sample t tests were calculated for a comparison of physical activity before and after the implementation of the structured after-school program. Students wore accelerometers an average of 45.72 ± 10.28 min/session. Total physical activity increased significantly from 36.21 ± 6.41 to 41.14 ± 6.76 min/session (p < 0.001). Moderate physical activity increased significantly from 9.29 ± 3.84 to 12.10 ± 5.96 min/session (p < 0.001), whereas vigorous activity significantly decreased from 8.02 ± 4.39 to 5.54 ± 5.32 min/session (p < 0.001). Overall, implementing a structured after-school program may be beneficial in increasing total physical activity, though its role in improving physical activity intensity is questionable.

Activity Intensity

The purpose of this investigation was to compare accelerometer activity counts and oxygen consumption between young and elderly individuals. Sixteen young (21.3±2.5 yrs) and sixteen elderly (66.6±2.9 yrs) participants completed 30 minutes of resting oxygen consumption to determine resting metabolic rate and four 6 min walking intensities ranging from 27 to 94 m·min−1. Resting oxygen uptake was significantly lower for the older participants. Exercise oxygen consumption was significantly higher for the elderly group. There were no significant differences in activity counts between groups at each of the exercise intensities. When using measured resting metabolic rate, activity counts of 824 and 2207 counts·min−1were associated with moderate (3 METs) physical activity intensity for the older and young participants, respectively. However, using standard resting metabolic rate (3.5 mL·kg−1·min−1), activity counts of 784 and 2009 counts·min−1were associated with moderate physical activity intensity for the elderly and young participants, respectively. These findings indicate that activity counts are similar across age groups even though the oxygen consumption of exercise is greater among elderly individuals.

Abstract Objectives Fear of falling (FoF) is common in older adults. Physical activity decreases as FoF increases. However, this association between physical activity and FoF may vary depending on activity intensity. The current study was performed to explore the associations between FoF and step count, light-intensity physical activity (LPA), and moderate/vigorous-intensity physical activity (MVPA) in community-dwelling older adults. Methods This cross-sectional observational study was held at a local community association center, with 242 older adults living independently in the community (mean age: 75.1 ± 5.4 years). FoF was defined using the Falls Efficacy Scale-International and categorized into three levels (low, moderate, and high). Physical activity was measured using a uniaxial accelerometer worn for 7 consecutive days, and by calculating daily step count, LPA, and MVPA, over this period. Results Step count and physical activity intensity showed significant linear trends across FoF severity (p < .01, respectively). High FoF decreased step count by approximately 2,000 steps/day. Further, high FoF was significantly associated with short durations of both LPA and MVPA. In addition, moderate FoF was associated with decreased LPA duration, even after adjustment for confounding variables. Discussion Physical activity decreased concomitantly with a rise in FoF severity. Moreover, the association between physical activity and FoF differed by physical activity intensity level in community-dwelling older adults. Further studies are needed to investigate the causal relationship between FoF and objective physical activity in this population.
