Parental Physical Activity and Resilience During Pandemic-Related Schooling at Home

The COVID-19 pandemic disrupted education for millions of families, forcing an instantaneous overlap in parental responsibilities and a resulting decline in personal mental health. Psychological resilience is an important contributor to handling prolonged stress. As physical activity (PA) is known to improve mental health, it is possible that PA during the COVID-19 education disruption could result in a significant difference in parental resilience. PURPOSE: The purpose of this study was to determine if PA levels during the COVID-19 educational disruption resulted in statistically significant differences in perceived resilience among parents of school-aged youth. METHODS: Fifty-six parents/guardians of youth aged 10-18 years completed a survey in fall of 2020. In addition to demographic questions, participants completed the recreational and sedentary portions of the World Health Organization’s (WHO) Global Physical Activity Questionnaire and the Adult Resilience Measure, resulting in overall resilience as well as personal (e.g., individual thoughts, behaviors) and relational (e.g., mutually empowering connections) resilience subscale scores. Parents were classified as meeting or not meeting WHO recommended PA levels. T-tests examined differences in resilience scores between groups. RESULTS: Overall, personal, and relational mean resilience scores for parents who did (n = 36) versus did not (n = 20) meet WHO recommended PA levels were 73.39 ± 8.66 versus 67.95 ± 9.30, 41.78 ± 5.25 versus 39.70 ± 4.78, and 31.61 ± 4.45 versus 28.25 ± 5.54 respectively. T-tests revealed a significant difference in total (t(54) = 2.19, p = .033, d = .61) and relational subscale scores (t(54) = 22.48, p = .016, d = .67), but no difference between personal subscale scores (t(54) = 1.46, p = .149, d = .41). CONCLUSION: Parents of school-aged youth who did not meet WHO recommended PA levels had significantly lower overall perceived resilience than those who met recommended levels. The significantly lower relational, but not personal, resilience scores seen in parents who did not meet WHO recommendations also suggests the importance of meaningful connections during PA. In short, meeting PA recommendations resulted in significantly higher perceived parental resilience during the COVID-19 educational disruption

No Difference in Stress Level Based on Physical Activity During the COVID-19 Pandemic Among Parents of School-Aged Children

Stress levels among children and parents have been heightened during the COVID-19 pandemic, especially with related changes in school structure. Regular physical activity (PA) represents a way to decrease stress levels and improve overall mood. Thus, regular PA is even more important during this period of prolonged stress as the pandemic continues to affect communities. PURPOSE: The purpose of this study was to examine differences in stress levels among parents of school-aged children during the COVID-19 pandemic based upon physical activity patterns. METHODS: Parents (n = 115, 91% female, 91% White) of school-aged children in the United States participated in surveys regarding their stress levels and physical activity. Stress levels were determined by the Perceived Stress Scale and dichotomized into Low Stress or Moderate/High Stress. To determine level of physical activity, participants also completed the Recreational and Sedentary portions of the WHO\u27s Global Physical Activity Questionnaire (7 questions). They were then dichotomized into “met” or “did not meet” World Health Organization’s recommendations for weekly physical activity (150 minutes moderate PA (MPA), 70 minutes of vigorous PA (VPA), or 600 MET*minutes). Perceived stress levels were analyzed using a chi-square test to determine any differences between the two groups based upon each WHO recommendation for physical activity (MPA, VPA, MET*minutes). RESULTS: A total of 47% of parents perceived themselves as having low stress while 53% reported moderate/high stress. A majority of parents did not meet WHO PA recommendations for weekly MPA (63%) nor VPA (64%) but did meet recommendations for weekly MET*min (59%). All chi-square tests were non-significant (MPA: Χ2 = .246, df = 1, p = .620; VPA: Χ2 = 3.422, df = 1, p = .064; MET*min: Χ2 = 1.361, df = 1, p = .243). CONCLUSION: The present study demonstrates that there was no significant difference in perceived stress levels based upon physical activity among parents of school-aged children during the COVID-19 pandemic, regardless of intensity of the physical activity. Even with the known positive benefits of PA to decrease stress, PA was not significantly associated with reduced stress levels among parents of school-aged youth. This finding could reflect stress exceeding normal levels due to the novel and unknown nature of the pandemic. It is also possible that PA did have a positive impact on stress levels but was too small to significantly counteract the abnormal increase in perceived stress. However, PA is still important for adults, including parents of school-aged youth, during the COVID-19 pandemic due to the numerous other health benefits it can provide beyond reducing stress levels

Living Situation and Physical Activity in the COVID-19 Pandemic Among American Private University Students

International Journal of Exercise Science 15(4): 1064-1074, 2022. Many university students experienced changes during the COVID-19 pandemic, including potential changes in physical activity (PA) levels and living situation. As PA behaviors in young adulthood help establish life-long habits and future health outcomes, the purpose of this study was to investigate overall change in PA, as well as change in PA due to living situation, among private university students during the COVID-19 pandemic. Private university students (n = 109) between 18 and 25 years of age completed an online survey that included the International Physical Activity Questionnaire – Short Form. T-tests examined changes in overall time spent in PA from before to during the COVID-19 pandemic, and the differences in MET-minute distributions between groups. Students performed significantly less activity during the COVID-19 pandemic than before (t(108) = 3.51, p = .001, d = 0.493), with 70.6% of all students meeting exercise recommendations before the pandemic and 51.4% after. Students living with vs. without a parent/guardian attained similar PA levels (t(107) = -.114, p = .910) before the pandemic (73.1% vs. 69.9%, respectively), but students living with a parent/guardian engaged in significantly less PA (t(107) = 2.04, p = .044, d = 0.475) than those living without a parent/guardian during the pandemic (37.5% vs. 57.1%, respectively). The declines in PA suggest the need for targeted interventions and education among private university students. In order to maximize the health benefits of PA, it is crucial that activity engagement return to at least pre-COVID-19 levels

Living Situation and Physical Activity in the COVID-19 Pandemic Among Private University Students

Physical activity levels among college students in private institutions were significantly altered by the COVID-19 pandemic. With COVID-19’s impact on universities, many students experienced transition, including a change in living situation. Behaviors in college help establish life-long habits that can determine health outcomes, so it’s important to investigate any declines in physical activity observed during the pandemic. PURPOSE: The purpose of this study was to assess differences in physical activity based on living situation among 18- to 25-year-old private university students during the COVID-19 pandemic. METHODS: Adults (n=109) between 18- and 25-years-old in the greater Houston area completed an online survey, which included the International Physical Activity Questionnaire – Short Form. Independent samples T-tests examined MET-minute differences based on living situation. RESULTS: Students living with versus without a parent/guardian attained similar activity levels (t(107) = -.114, p = .910) before the pandemic, but students living with a parent/guardian engaged in significantly less activity (t(107) = 2.04, p = .044) during the pandemic. CONCLUSION: The pandemic presented a strong obstacle to physical activity participation among private university students. Students living with a parent/guardian during this time saw an even more significant decrease in physical activity. Based on these findings, targeted interventions should be made to increase the physical activity of college students during COVID-19, especially for those living at home with a parent or guardian

Physical Activity Independently Predicts Perceived Stress During the COVID-19 Pandemic in Private University Students

International Journal of Exercise Science 15(7): 1680-1691, 2022. Physical activity has significantly declined during the COVID-19 pandemic. Declines in physical activity have correlated with increased levels of perceived stress, though studies examining physical activity and stress have failed to account for critical confounds. The present study aims to determine whether physical activity independently predicts perceived stress in students attending private four-year universities. Physical activity, socioeconomic status, resilience, gender, and perceived stress data were collected from 85 students and used in a multiple linear regression analysis. The regression model accounted for 43.5% of the variance in perceived stress (R2 = .462, p \u3c .001). Total physical activity significantly and inversely predicted perceived stress (β = –.229, p = .007) in students irrespective of other covariates. Socioeconomic status, resilience, and gender also independently and significantly predicted perceived stress. Findings should be leveraged by university staff to promote psychological well-being and wholistic health initiatives incorporating physical activity as a primary and modifiable component

Effects of a College-Mentored Physical Activity Program for Elementary Students

Health risks of a sedentary lifestyle for children, defined as being less than 5,000 steps per day, include unfavorable indicators of body composition and cardio-metabolic risk. Results of school-based physical activity interventions to increase physical activity levels have been mixed. However, mentorship programs have shown promise. Previous mentorship programs have relied on peer-to-peer mentorships, with participants being of a similar age group. College mentors present an alternative and low-cost resource that may also provide positive results, yet have been largely ignored in research studies to date. PURPOSE: The purpose of this study was to investigate the impact of a novel, individualized college-mentored physical activity program on physical activity levels among older elementary school students. METHODS: Fifth grade students (n = 12) were paired one-to-one with local college mentors for 30 minute bi-weekly running sessions on the elementary school campus for six weeks. Multiple assessments from activity trackers were compared on intervention versus non-intervention days using paired-samples t-tests. RESULTS: Significant increases in steps (t(11) = 8.056; p ≤ .001) and moderate-to-vigorous activity (t(11) = 5.202; p ≤ .001) were seen on intervention days, as compared to non-intervention days. The average increase in step count on intervention days (6,381) versus non-intervention days (3,158) also resulted in students being elevated out of a sedentary classification. CONCLUSION: Individualized mentoring from college students significantly increased multiple assessments of physical activity, including minutes of moderate-to-vigorous activity and number of steps taken. Perhaps most notably, the mentored physical activity program promoted students from a sedentary to active lifestyle on intervention days as determined by step count. This novel high-impact and low-cost approach should be further developed for future school-based physical activity programs and research

DISC1 regulates N-methyl-D-aspartate receptor dynamics:abnormalities induced by a Disc1 mutation modelling a translocation linked to major mental illness

Abstract The neuromodulatory gene DISC1 is disrupted by a t(1;11) translocation that is highly penetrant for schizophrenia and affective disorders, but how this translocation affects DISC1 function is incompletely understood. N-methyl-D-aspartate receptors (NMDAR) play a central role in synaptic plasticity and cognition, and are implicated in the pathophysiology of schizophrenia through genetic and functional studies. We show that the NMDAR subunit GluN2B complexes with DISC1-associated trafficking factor TRAK1, while DISC1 interacts with the GluN1 subunit and regulates dendritic NMDAR motility in cultured mouse neurons. Moreover, in the first mutant mouse that models DISC1 disruption by the translocation, the pool of NMDAR transport vesicles and surface/synaptic NMDAR expression are increased. Since NMDAR cell surface/synaptic expression is tightly regulated to ensure correct function, these changes in the mutant mouse are likely to affect NMDAR signalling and synaptic plasticity. Consistent with these observations, RNASeq analysis of the translocation carrier-derived human neurons indicates abnormalities of excitatory synapses and vesicle dynamics. RNASeq analysis of the human neurons also identifies many differentially expressed genes previously highlighted as putative schizophrenia and/or depression risk factors through large-scale genome-wide association and copy number variant studies, indicating that the translocation triggers common disease pathways that are shared with unrelated psychiatric patients. Altogether, our findings suggest that translocation-induced disease mechanisms are likely to be relevant to mental illness in general, and that such disease mechanisms include altered NMDAR dynamics and excitatory synapse function. This could contribute to the cognitive disorders displayed by translocation carriers

Organized Sports and Physical Activities as Sole Influencers of Fitness: The Homeschool Population

Homeschool children may rely solely on organized sports and physical activities to achieve recommended levels of physical activity and fitness. The purpose of this study was to investigate differences in fitness levels between homeschool children who did, and did not, participate in organized sports or physical activities, and then examine relationships between hours per week in sports or physical activities and cardiorespiratory fitness as measured by portions of the FitnessGram® test battery. Organized sports/physical activity participation information was gathered on 100 children ages 10–17 years who completed tests of upper, abdominal, and cardiorespiratory fitness. The current investigation revealed that participation alone was not associated with higher levels of physical fitness as assessed by the 90° push-up test or curl-up test nor was time in participation related to cardiorespiratory fitness as assessed by the Progressive Aerobic Capacity Endurance Run (PACER). These activities alone may be insufficient for meeting physical activity recommendations and improving physical fitness. Therefore, children and adolescents educated at home may need additional opportunities to participate in unstructured daily physical activity

Validation of Cardiorespiratory Fitness Measurements in Adolescents

Cardiorespiratory fitness (CRF) is an important indicator of adolescent cardiovascular well-being and future cardiometabolic health but not always feasible to measure. The purpose of this study was to estimate the concurrent validity of the non-exercise test (NET) for adolescents against the Progressive Aerobic Capacity Endurance Run (PACER®) and direct measures of VO2max as well as to examine the concurrent validity of the PACER® with a portable metabolic system (K4b2™). Forty-six adolescents (12–17 years) completed the NET prior to performing the PACER® while wearing the K4b2™. The obtained VO2max values were compared using linear regression, intra-class correlation (ICC), and Bland–Altman plots, and α was set at 0.05. The VO2max acquired directly from the K4b2™ was significantly correlated to the VO2max indirectly estimated from the NET (r = 0.73, p < 0.001, r2 = 0.53, ICC = 0.67). PACER® results were significantly related to the VO2max estimates from the NET (r = 0.81, p < 0.001, r2 = 0.65, ICC = 0.72). Direct measures from the K4b2™ were significantly correlated to the VO2max estimates from the PACER® (r = 0.87, p < 0.001, r2 = 0.75, ICC = 0.93). The NET is a valid measure of CRF in adolescents and can be used when an exercise test is not feasible
