Correlation and Change in Physical Activity and Physical Fitness across Four Years of College Students after One Year of COVID-19 Lockdown

Personality traits and Chinese college students' satisfaction with physical education classes: the mediating role of trait fluency and the moderating role of physical education class difficulty

Background

This study aims to investigate the impact mechanism of personality traits on physical education satisfaction among college students, validating the mediating effect of trait flow and the moderating effect of physical education difficulty. By analyzing the influence mechanism of personality traits on college students' satisfaction with physical education classes, it helps to explore more channels to enhance satisfaction with physical education classes.

Methods

A questionnaire survey was conducted using the Big Five Personality Scale, the Physical Education Class Satisfaction Scale, the Trait Fluency Scale, and the Physical Education Class Difficulty Scale with 868 public physical education students in 10 universities in Shanghai. Moderated mediation modeling was conducted using Hayes' PROCESS macro.

Results

Personality traits are positively correlated with physical education satisfaction, and the predictive effect is significant (β = 0.786, p < 0.001). This association is mediated by trait fluency (indirect effect: β = 0.797, p < 0.001), accounting for 62.7% of the total effect. Physical education difficulty significantly moderates the predictive effects of personality traits on physical education satisfaction (β = -0.183, p < 0.01) and trait fluency (β = -0.130, p < 0.001). Additionally, physical education difficulty significantly moderates the predictive effect of trait fluency on physical education satisfaction (β = 0.172, p < 0.001).

Conclusion

Personality traits predict physical education satisfaction, with trait fluency playing a mediating role, and physical education difficulty moderates the direct and indirect paths through which personality traits influence physical education satisfaction.

The long-term impact of the COVID-19 pandemic on physical fitness in young adults: a historical control study

The strength of evidence regarding long-term changes to fitness resulting from the coronavirus disease 2019 (COVID-19) lockdowns is deficient. This two-site retrospective study aimed to investigate the long-term changes in physical fitness among young adults a year after the onset of the pandemic using a robust historical control. University freshmen who underwent physical fitness tests in 2019 and completed a follow-up in 2020 (study group) were included. The primary focus was to compare the current cohort with a historical control group who completed the same tests a year prior (2018). A total of 5376 individuals were recruited, of which 2239 were in the study group. Compared with the control, the study group exhibited a decrease in anaerobic fitness, with an overall difference of -0.84 (95% confidence interval [CI], [-1.33 to -0.36]); declines in aerobic fitness, with a difference of -2.25 [-3.92 to -0.57] for males and -4.28 [-4.97 to -3.59] for females; a reduced explosive fitness (-2.68 [-3.24 to -2.12]); and a decreased upper-body strength in females (-1.52 [-2.16 to -0.87]). The fitness of young adults has been considerably compromised by COVID-19 lockdowns, highlighting the importance of promoting physical activity to prevent long-term health implications.

The Influence of COVID-19 on University Students' Well-Being, Physical Activity, Body Composition, and Strength Endurance

BACKGROUND

Very few scientific studies have simultaneously evaluated changes in well-being (WB), physical activity (PA), and strength endurance (SE) based on results from before and during the COVID-19 pandemic.

AIM

The aim of the study was to assess WB, PA, and SE levels, as well as body composition parameters in university students before and during the pandemic.

METHODS

The study included 30 males and 30 females (mean age: 21.7 ± 2.51 and 21.6 ± 2.34 years, respectively). Well-being using the Self-Perception Questionnaire (POMS), PA from the Polish regular version of the International Physical Activity Questionnaire (IPAQ), body composition parameters using the InBody 270 analyzer, and SE based on the results of a 12 min test involving a Concept 2PM-5 rowing ergometer were assessed before and during the pandemic.

RESULTS

An assessment of university students' WB revealed a significant increase in variables such as tension, depression, anger, confusion, and a significant decline in vigor (p < 0.05). In both sexes, PA and SE decreased significantly-from 2115.4 to 1822.8 METs-min/week and from 2184.5 to 2035 m, respectively, in males, and from 1793.5 to 1699.8 METs-min/week and from 2021.5 to 1943.8 m, respectively, in females. At the same time, body mass and BMI values increased significantly (p < 0.001) in both females and males.

CONCLUSIONS

The COVID-19 pandemic caused a significant decrease in WB, PA and SE levels in young females and males, and led to a significant increase in their body mass and BMI.

The Effect of Physical Activity on Anxiety: The Mediating Role of Subjective Well-Being and the Moderating Role of Gender

PURPOSE

To explore the role of subjective well-being in the relationship between physical activity (PA) and anxiety and whether the model is moderated by gender.

METHODS

We conducted a questionnaire survey by selecting 1153 college students from Shanghai Jiao Tong University in China, and data were analyzed using SPSS, Process, and AMOS.

RESULTS

1) Correlation analysis showed that PA, subjective well-being, and anxiety were significantly related. Also, we found subjective well-being to differ significantly on the demographic variable registered residence. 2) Subjective well-being played a mediating role between PA and anxiety. 3) Gender played a moderating role in the direct effect of PA on anxiety, shown by the significant difference in the path coefficients between the male and female models (male: β = -0.03, p > 0.05, female: β = 0.10, p < 0.05).

CONCLUSION

Subjective well-being mediated the relationship between PA and anxiety, and gender moderated the mediating model. These findings highlight the importance of PA in reducing anxiety and increasing subjective well-being in the context of an epidemic.
