The effects of perceived psychological, educational, and financial impact of COVID-19 pandemic on Greek university students' satisfaction with life through Mental Health.

BACKGROUND: The purpose of this study was to provide an operating mechanism for understanding the effects of COVID-19's on satisfaction with life, subject to students' general mental health METHODS: A sample of 1653 Greek speaking university students (72.4% females, 65.3% undergraduate, M age=26.1) completed an online survey including measures for perceived psychological, academic, and financial impact of the COVID-19 pandemic, general mental health and satisfaction with life. RESULTS: A mediation model was tested to illuminate these relationships by considering students' general mental health as a mediator. Findings demonstrated that there were significant direct effects of perceived COVID-19 impact on participants' financial status on satisfaction with life and indirect effects of perceived COVID-19 impact on participants' financial status and academic performance respectively on satisfaction with life through general mental health. LIMITATIONS: The study's cross-sectional design, self-report data and snowball sampling. CONCLUSIONS: The findings add to our understanding of the relationship between perceived COVID-19 impact and life satisfaction among university students, and they shed light on the critical role of general mental health in mediating the relationship. Targeting the factors that influence general mental health can help to mitigate potential problems while also finding ways to improve mental health and well-being.

An eight week school-based intervention with circuit training improves physical fitness and reduces body fat in male adolescents.

BACKGORUND: School-based intervention programs have been found to effectively improve various fitness and health parameters. However, only few studies so far examined the effect of circuit training in school environment during physical education (PE) classes. The aim of the current study was to examine the effects of an eight-week circuit training on physical fitness and body fat in male adolescents. METHODS: Thirty nine, 16-year old male high-school students participated in the current study. The students were randomly assigned to intervention and control groups. The intervention period lasted eight weeks and consisted of two circuit training sessions per week performed during regular PE classes. Total body fat was calculated by using bioelectrical impedance analysis. Physical fitness parameters such as cardiorespiratory fitness, flexibility, jumping ability and isometric arm strength were assessed through a battery of field tests. Finally, resting heart rate and blood pressure levels were assessed with an automatic monitor. RESULTS: By the end of the intervention period, total body fat and resting systolic blood pressure were significantly lower while cardiorespiratory fitness was significantly improved in the circuit training group only (P<0.05). In the control group Body Mass Index and total body fat percentage were significantly increased when compared pre- and post-intervention period (P<0.05). CONCLUSIONS: Eight weeks of circuit training during PE classes appeared to be effective in improving various physical fitness parameters and reducing fatness in male adolescents.

The relationship between physical fitness and obesity among a sample of adolescents in Cyprus.

Recent data revealed that adolescent obesity appeared to be a rising problem in Cyprus. However, there is a scarcity of published data regarding fitness-related parameters, which could contribute for the presence of obesity in Cyprus' adolescence population. The aim of the current study was to investigate the association between adolescent obesity, body composition, and fitness levels. A total of 270 high school students volunteered to participate in this cross-sectional study. Body mass and height were assessed in order to calculate body mass index, while body fat percentage was calculated by using bioelectrical impedance analysis. Physical fitness parameters were assessed through a battery of field tests. Body fat was inversely associated with cardiorespiratory fitness levels, sprint and jumping performance, as well as with the frequency of physical education class sessions per week (p<0.05). The adolescents with high body fat were found to exhibit significant reductions in all the fitness related parameters (p<0.05), except with the arm strength (p>0.05). This study is the first to uncover an inverse association between high body fat and fitness-related parameters among a sample of adolescents in Cyprus. These data can be used in order to develop effective interventions aiming to counterbalance obesity and improve the overall health and the quality of life of adolescents.

Emotional exhaustion, absenteeism, and turnover intentions in childcare teachers: examining the impact of physical activity behaviors.

Drawing on Salmon's (2001) unifying theory of the beneficial effects of physical exercise, we examined physical activity behaviors as an important, but understudied, buffer against experiences of emotional exhaustion, absenteeism, and turnover intentions in 189 childcare teachers. Structural equation modeling revealed that workplace and leisure-time physical activity were negatively related to emotional exhaustion, which in turn, was positively related to teacher migration and attrition intentions. Post-hoc analyses revealed indirect (mediated) effects between physical activity behaviors and teacher turnover intentions via emotional exhaustion. This theoretically driven model fit the data better than an alternative model whereby emotional exhaustion predicts physical activity behaviors.
