RESUMEN

Rapid automatized naming (RAN) has been proven to be important for students' academic performance, but it remains unclear whether and how dealing with stressors (e.g., active coping) is associated with children's development of RAN. To examine this question, this research views the growth of RAN as a cross-stressor adaptation process and proposes that school-aged children may build up adapted and modified stress response systems through active coping in dealing with stressors and cognitive tasks. Based on the broaden-and-build theory and the mind-body unity theory, we explored the impact of active coping on RAN and hypothesized that subjective vitality and aerobic fitness chain mediated the relationship between active coping and RAN. We used two Likert-like scales to measure active coping and subjective vitality, used a number-reading task to measure RAN, and used the progressive aerobic cardiovascular endurance run (PACER) test to measure aerobic fitness. We recruited 303 elementary students in grades 3-5 in China. Results showed that both subjective vitality and aerobic fitness mediated the impact of active coping on time for RAN. Further, the chain indirect effect of active coping→subjective vitality→aerobic fitness→time for RAN was significant, but the reversed chain mediation was not significant. General resources (e.g., subjective vitality) have been shown to be relatively more important than simple physical resources (e.g., aerobic fitness) for RAN. These preliminary findings may contribute to both the cross-stressor-adaptation and active coping literature and have potential implications for improving RAN in school-aged children.

RESUMEN

For a long time, studies on the peer effect of physical activity among adolescents have focused on relevance rather than causality. This article provides empirical evidence of the peer effect of physical activity among adolescents using data from the China Education Panel Survey. The results show that the peer effect increases physical activity by about 6.757-8.984 min per week among classmates, a finding consistent with previous studies. Using the instrumental variable approach and considering the potential missing variables, the peer effect increases physical activity by 23.923-27.410 min per week, representing a threefold increase. In addition, the general attitude towards sports in class plays a significantly influential role, accounting for 20% of the peer effect of physical activity.

RESUMEN

Previous research has shown many benefits of mindfulness for physical and psychological health, including its link to such health behaviors as increased physical activity (PA). We re-examined the association between mindfulness and PA to better understand a possible mediating role of eudaimonic well-being in this association, while controlling for participants' age, gender, and affect. We had 738 undergraduate student participants (45.0% females; M age = 19.58 years) complete measures of trait mindfulness, eudaimonic well-being, and PA, and we used age, gender, and affect as covariates in a single-wave assessment. We conducted this mediation analysis with a bootstrapping technique to produce 10,000 resamples. We replicated findings of a significant relationship between mindfulness and enhanced eudaimonic well-being (ß = 0.474, p < 0.001), which in turn contributed to increased PA (ß = 0.193, p < 0.001). The bootstrapping method indicated a significant indirect effect of eudaimonic well-being (ß = 0.092, 95% CI = [0.043, 0.142]) in the relationship between mindfulness and PA through eudaimonic well-being. Thus, eudaimonic well-being may mediate the connection between mindfulness and PA. College administrators should consider incorporating mindfulness into health promotion programs as a means of enhancing college students' well-being and health behaviors.

RESUMEN

Objective: To explore the mediating effect of self-efficacy on the relationship between the proactive personality and academic performance of college students in different sports groups. Methods: A questionnaire survey is used to study 552 college students. The research tools include the proactive personality scale, the self-efficacy scale table (general, academic, and self-regulation efficacy scale tables), and the academic performance self-report scale table. This research employs SPSS 11.0 statistical software to carry out correlation analysis, regression analysis, and t-tests on the data collected, while the test of mediating effect is carried out by AMOS 22.0. Results: (1) The degree of self-efficacy and academic performance of college students participating in physical activities is significantly greater than that of the non-sports group; (2) the proactive personality level of the sports group is significantly higher than the non-sports group in the dimension of "conscientiousness"; (3) a confirmatory factor analysis of the mediating effect hypothesis model, using the structural equation model, found that self-efficacy plays a full mediating role in the relationship between proactive personality and academic performance; the direct effect of self-efficacy on the proactive personality and academic performance of college students in different sports groups is not significant. Conclusion: College students involved in sports exercise have higher scores on some items about proactive personality than non-sports groups; girls' self-efficacy level is higher than that of boys; self-efficacy plays a full mediating role in the relationship between proactive personality and academic performance; self-efficacy had no significant effect on proactive personality and gender in different sports groups.

RESUMEN

BACKGROUND: Wearable activity trackers hold the potential for enhancing health and fitness, but the use of wearable activity trackers has remained largely unexplored in older adults. The purpose of the current study was to examine the effectiveness and acceptability of wearable activity trackers for promoting physical activity (PA) in older adults living in retirement communities. METHODS: Forty older adult participants (mean age = 85.4 years) used a wearable activity tracker (Fitbit InspireHR) for 12 weeks. Participants were provided with personalized activity goals and weekly feedback of PA during the 12 weeks. The main outcomes were daily step counts collected at baseline and the end of the intervention, and participants' experiences of using the wearable activity tracker assessed after the 12-week intervention through an 8-item questionnaire and individual interviews. RESULTS: Participants used the activity tracker on 97.5% of measured days and had an average increase of 900 steps/day (p < 0.001). The Acceptance questionnaire revealed that the wearable activity tracker was acceptable, useful, and easy to use. Participants found that wearable activity trackers helped improve self-awareness and motivation of PA but reported a few concerns regarding the comfort of wearing the activity trackers and the ease of reading visual feedback. CONCLUSIONS: Wearable activity trackers lead to a small but significant increase of PA and are perceived as acceptable and useful in older adults. Given the rapidly growing older population, wearable activity trackers are promising tools that could be used in large-scale interventions to improve PA and health in older adults. TRIAL REGISTRATION: Registered on Clinicaltrials.gov # NCT05233813 (Registered on 10/02/2022).

RESUMEN

This study examined the association of different intensity levels of physical activity and positive thinking with a global sleep quality among college students. The research question was: to what degree were the different intensity levels of physical activity and positive thinking significantly associated with the global sleep quality among college students? We recruited students, who enrolled in regular physical education classes during a fall semester at a major public university. 553 students signed the consent form and indicated their voluntary participation in this study. The final data set for analysis consisted of 403 college students with the mean age of 19.01 years ± 1.559 years (217 males vs. 186 females) based on the results of data screening. They completed three questionnaires: International Physical Activity Questionnaire (IPAQ), Pittsburgh Sleep Quality Index (PSQI), and Positive Thinking Scale (PTS) during a regular physical education class. The multiple regression model revealed that vigorous-intensity physical activity, positive thinking, and negative thinking were collectively and individually associated with the Global PSQI sleep quality (F = 19.389, p = .000), explaining 12.8% of the total variance in the Global PSQI sleep quality for the total sample. College students' engaging in vigorous intensity level of physical activity, and having a good level of positive thinking and a low level of negative thinking were both collectively and individually linked to the Global PSQI sleep quality.

RESUMEN

BACKGROUND: To increase psychological well-being and physical activity (PA) behaviors, our pilot study used the social ecological model as the framework to design the 4Active intervention, focusing on multicomponent exercise group lessons at the interpersonal level and self exercise enhanced by activity trackers at the individual level. The purpose of this pilot study was to examine the effectiveness of the two-level 4Active intervention in improving psychological well-being and PA participation in older adults living in retirement communities. METHODS: Participants were 27 older adults with a mean age of 85.9 ± 9.3 years. Based on the two-arm, quasi-experimental study design, fourteen older adults (2 men, 12 women) living in one retirement community (RC) were assigned into the intervention group receiving the two-level 4Active intervention, whereas 13 older adults (1 man, 12 women) living in another RC were allocated to the active control group receiving group exercise intervention alone for eight weeks. One week before and after the interventions, the participants were pre-tested and post-tested in psychological well-being (i.e., life satisfaction, subjective happiness, positive affect, and negative affect) and weekly PA minutes (i.e., weekly walking, vigorous, moderate, and total PA minutes). The data were analyzed be means of descriptive statistics, independent sample t-tests, and ANCOVA repeated measures. RESULTS: The results of ANCOVA repeated measures indicated that both groups maintained their slightly high or very high levels of life satisfaction, happiness, and positive affect over times. However, the two-level 4Active intervention group showed significant decreases in negative affect (F = 4.78, p = 0.04, η2 = 0.23) and significance increases in weekly moderate PA (F = 10.355, p = 0.004, η2 = 0.310) compared with the active control group over time. CONCLUSION: It is concluded that engaging in the two-level 4Active intervention including group-based multicomponent exercises and technology-enhanced self-exercises is more effective in decreasing negative affect and increasing weekly moderate PA METS-min in physically and cognitively frail older adults over time, compared with attending the group exercises alone.

RESUMEN

ObjectiveThe aim of this study was to examine the associations between physical activity (PA) and subjective well-being (SWB) by focusing on the intensity of PA and different components of SWB. Participants: The sample included 723 undergraduate students (mean age = 19.3 years). Methods: Participants responded to questionnaires measuring life satisfaction, happiness, positive affect, negative affect, vigorous-intensity PA, moderate-intensity PA, and walking. Multiple regression models were performed with the SWB variables as the outcomes and PA variables as the predictors while controlling for age and sex. Results: While vigorous-intensity PA was the only significant predictor for life satisfaction, both moderate-intensity PA and vigorous-intensity PA were positively associated with happiness and positive affect and negatively associated with negative affect. Walking was not associated with any component of SWB. Conclusion: PA has a positive relationship with SWB in college students and this relationship differs by the intensity of PA and the component of SWB.

RESUMEN

Knee Osteoarthritis (KOA) is the most common type of knee joint injury and also a risk factor for multiple health consequences and is prevalent among older women. The updated clinical guidelines for KOA treatment by the American Rheumatism Association recommend Tai Chi exercise. However, a literature review outlined limitations in Tai Chi intervention implementations. This study aimed to address some of the gaps. This study selected thirty female patients to participate in Tai Chi exercises and undergo relevant tests. The subjects were randomly assigned to Tai Chi or education groups. Independent sample t-tests were conducted to compare the difference in health indicators between the two groups after the intervention. The difference-in-differences (DID) regression was performed to assess the difference in the health outcomes between the two groups at baseline and follow-up and the difference in the differences. After the completion of the intervention, the Tai Chi group reported significantly improved KOA symptoms, physical fitness, and health status indicators than the control group. Specifically, the group differences were significantly larger at the baseline than at the follow-up. Our findings provide compelling evidence of the effects of the innovative Tai Chi exercise prescription specifically designed for KOA patients. The empirical evidence on its effectiveness in alleviating KOA symptoms and improving the overall health of middle-aged and elderly women with KOA suggested that Tai Chi intervention exercise has huge prospects for integration in KOA rehabilitation therapy.

RESUMEN

Objective: The purpose of the current study was to examine the bidirectional relationship between physical activity (PA) and purpose in life in an older adult sample using longitudinal data. Method: Data were collected from three waves (2006, 2010, and 2014) of the Health and Retirement Study. A total of 4591 participants who had complete information of PA and purpose in life at baseline were included in the current study. A series of cross-lagged models were tested separately for vigorous-intensity PA, moderate-intensity PA, and light-intensity PA. Results: While higher levels of purpose in life were associated with more frequent engagement in future vigorous-intensity PA, moderate-intensity PA, and light-intensity PA, none of the PA variables predicted subsequent purpose in life. Discussion: The results did not support a reciprocal relationship between PA and purpose in life in older adults. It is more likely that purpose in life predicts PA, rather than vice versa.

RESUMEN

This study aimed to test the validity and reliability of the Physical Education (PE) Metric Assessment Rubrics for assessing 4th-grade students' manipulative skill competency and examine how well they demonstrated manipulative skill competency. Participants were 4th-grade students at six elementary schools in China. A total of 535 4th-grade students were assessed their soccer skills and 819 4th-grade students were assessed their basketball skills using the PE-Metric Assessment Rubrics. The results found that the soccer and basketball skill assessments had a high degree of internal consistency. And the results showed that the soccer and basketball skill assessment rubrics had a good factor structure. The students' mean score in soccer and basketball skills assessment was lower than the Overall Competent Level. Further, the t-test indicated that soccer and basketball skill assessments had a significant difference in the mean score of Overall Competent Level between the boys and the girls. The PE-Metric Assessment Rubrics were valid and reliable assessment tools for assessing the manipulative skill competency in soccer and basketball skills among 4th-grade students in China. This study suggested that Chinese elementary school students need to improve basic manipulative skill competency in soccer and basketball skills.

RESUMEN

OBJECTIVE: This study aimed to examine the association between physical activity (PA) and subjective well-being (SWB) in Chinese college students, and to determine if the perceived health mediated this association, while both controlling for age, gender, and body mass index (BMI). PARTICIPANTS: 1204 college students (47.8% female, mean age =19.76 ± 1.29 years) voluntarily completed a set of questionnaires in a single-wave (cross-sectional) assessment in 2016. METHODS: Participants answered questions measuring happiness, life satisfaction, PA, and perceived health. Five multiple regression models were performed to test the mediating effect. Age, gender, and body weight status were added to all models as covariates. RESULTS: Meeting the moderate- to vigorous-PA (MVPA) guideline (>150 min/week) was associated with higher levels of happiness and life satisfaction (p's < 0.001). These positive associations were weakened while controlling for the perceived health. Gender was a significant covariate for happiness and body weight status was a significant covariate for life satisfaction. Age was not a significant covariate for all models. CONCLUSION: PA is positively associated with SWB among college students and this positive association is partially mediated by the individual levels of perceived health. Universities might consider providing exercise programs and advocating students participating more MVPA as effective ways to support students' mental and emotional well-being.

RESUMEN

The development of movement skills in children is a critical element in promoting physical activity and other positive health trajectories over their lifetime. A reliable and valid assessment tool is essential for evaluating children's movement skills in daily physical education environments. The purpose of this study was to examine the validity of Children's Motor Skills Quotient (CMSQ) used in the classroom setting. Six raters conducted evaluation to participants, and a total of 734 children completed all the test items and were included in the study. Descriptive statistics and Rasch analysis were used in this study. The descriptive statistics were mainly used for calculating the mean, standard deviation, percentage, and internal consistency coefficient. Rasch analysis was used to verify the fitting statistics, project difficulty, and functional differences of the items of the CMSQ. The findings showed that the CMSQ met the assumption of the Rasch model, including the unidimensionality, local independence, person measure, and item difficulty hierarchy. The CMSQ also demonstrated adequate interrater reliability and internal consistency. The differential item functioning (DIF) demonstrated a few items showing different probabilities across sex and age. To maintain the item difficulty hierarchy of the CMSQ, no items were deleted. Overall, the CMSQ seems to have appropriate test items with an appropriate rating scale structure for measuring 6-9-year-old children's movement skills in the physical education classroom environment.

RESUMEN

This pilot study examined the fidelity and feasibility of a multicomponent physical activity intervention in a retirement community. Eighteen older adults participated in an 8-week intervention. The intervention included offering group exercise lessons, combined with providing participants wearable activity trackers. Quantitative and qualitative data were collected to assess the feasibility and fidelity. The retention of the study was 83.3% and the average attendance of group lessons was 88.2%. Participants wore the activity trackers on 93.9% of the required days. Individual interviews indicated that participants were generally satisfied with the intervention. However, the Tai Chi session of exercise lessons and the activity trackers were not favored by the majority of the participants. Future interventions should provide tailored and adaptable exercise programs to meet the various physical health conditions of older adults and ease the use of technology to facilitate behavior change.

RESUMEN

Objectives: This study examined the relationship between physical activity, sleep and depression among college students and gender differences in physical activity, sleep and depression. Methods: Participants were 1143 students from a large public university in Beijing and completed three questionnaires to measure their physical activity habits, sleep patterns, and depression levels. Data from were analyzed using descriptive statistics, stepwise regression, and an independent t test. Results: Results indicated that vigorous physical activity and sleep variables significantly predicted depression levels for the overall sample (F = 77.286, p = .000). When examined by gender, vigorous and moderate physical activity variables significantly predicted depression for males (t = -2.772, p = .006; t = -2.622, p = .009), whereas no level of physical activity had a significant relationship with depression for females. Conclusions: Rigorous physical activity and quality sleep may be beneficial to helping college students reduce and regulate depressive symptoms, however may vary by gender.

RESUMEN

BACKGROUND: The health benefits of physical activity (PA) have been well documented in the literature. The relationship between PA and psychological well-being (PWB) has received increasing attention. AIM: This study aimed to systematically review the measurement of PWB in PA studies and examine the major findings of these studies. METHODS: We conducted a systematic search in PubMed/Medline, Web of Science, PsycINFO, and SportDiscus for articles published from their inception to October 2018 to identify empirical studies that investigated the relationship between PA and PWB. For each study meeting the inclusion criteria, we identified its measure for PWB and reviewed its main findings. RESULTS: The literature search identified 53 studies examining the relationship between PA and PWB and 48 measurement scales for assessing various domains of PWB. The measurement scales were further classified as measures of hedonic well-being (n = 11), eudaimonic well-being (n = 10), mental ill-being (n = 18), or multifaceted well-being (n = 9). Twenty-seven out of 29 observational studies and nineteen out of 24 intervention studies found favorable associations between PA and at least one domain of PWB. CONCLUSIONS: Although the findings in the empirical studies generally support a positive relationship between PA and PWB, the specific psychological domains measured in these studies vary considerably. In addition, the definition of PWB in these studies is incomplete and unclear. Future studies are suggested to choose measurement scales based on a clear and theoretically based definition of PWB and focus more on hedonic well-being and eudaimonic well-being.

RESUMEN

This study aimed to examine the effects of active workstation use on the executive function by measuring the three components of executive function (Inhibition, Updating, and Shifting) during sitting, standing, and walking at an active workstation with different speeds. Twenty-four college students completed a cognitive test battery while sitting, standing, walking on an active workstation with a self-selected speed (mean = 2.3 km/h) and a faster speed (mean = 3.5 km/h). The three components of executive function (Inhibition, Updating, and Shifting) were assessed by Stroop task, N-back task, More-odd shifting task, respectively. Performance of each task was determined by the response time and accuracy. Repeated measures ANOVAs were conducted with workstation condition and trial type as within-subjects factors. There were no significant main effects for workstation condition and no interaction between workstation condition × trial type in Stroop task and More-odd shifting task. There was a significant main effect for workstation condition (F (3, 69) = 4.029, p = 0.011) and interaction effect between workstation condition × trial type (F (6, 138) = 9.371, p < 0.001) in N-back task. Decomposition of the interaction showed that accuracy of 2-back task in self-paced walking was significantly lower than that in sitting condition (p = 0.017) and in standing condition (p < .001). But there was no difference in accuracy of 2-back task between self-paced walking condition and faster walking condition (p = 0.517). Our results suggest that using an active workstation may have a selective impact on three components of executive function, in which the Updating may be impaired to a certain extent while the Inhibition and Shifting remain unaffected.
