Playing Roles in Work and Family: Effects of Work/Family Conflicts on Job and Life Satisfaction Among Junior High School Teachers
2021
Junior high school teachers play an essential role in education. How to relieve the worries of teachers, that is, the pressure they face in the fields of work and family, has increasingly become an urgent problem. Based on the COR theory, this study aims to investigate the effects of two types of work/family conflicts (i.e., work-family conflict and family-work conflict) on teachers’ job and life satisfaction. We adopted a handy sample method and collected a total of 560 junior high school teachers data. The results confirmed that both work-family and family-work conflicts are not significantly related to junior high school teachers’ job satisfaction and life satisfaction directly. However,…
Burnout as an important factor in the psychophysiological responses to a work day in Teachers
2010
Burnout syndrome is an important psychosocial risk in the job context, especially in professions with a strong social interaction, as in the case of teaching. This study analyses the role of burnout in the psychophysiological responses to a work day in teachers. High burnout was related to worse mood, and higher perceived stress throughout the work day. Moreover, burnout is positively related to systolic blood pressure and negatively related to salivary cortisol levels at the beginning of the work day. Higher scores of burnout in teachers are also related to lower heart rate in the middle of the work day. The psychophysiological responses to a work day are specifically associated with the d…
Role Stress: Burnout Antecedent in Nursing Professionals
1993
Abstract Burnout syndrome has been described by different authors as a reaction to work stress. Hence both the role stress components–role ambiguity and role conflict–appear in the literature as burnout antecedent variables. The correlation between these variables is positive. On the other hand, the work social support (from supervisors and colleagues) is a variable with influence on both role stress and burnout, so the people who perceive higher work social support feel lower role stress and lower burnout than the people who perceive lower social support. In this study we present the results of a correlational study of role ambiguity, role conflict, burnout levels (tested with Maslach Burn…
The Influence of Fatigue on Throwing and YBT-UQ Performance in Male Adolescent Handball Players
2020
Purpose: The goal of the present study was to assess the effects of fatigue on throwing and Upper Quarter Y Balance Test (YBT-UQ) performance in male adolescent handball players. We hypothesized that throwing and YBT-UQ performance will be decreased in response to an upper-body fatigue-protocol.Method: All male participants (N = 24, age: 14.8 ± 0.7 yrs) were handball players of a regional youth selection team. A radar gun was used for the assessment of throwing velocity. The YBT-UQ was executed assessing medial, inferolateral and superolateral reach directions normalized to the upper limb length together with a composite score. Immediately following a fatigue protocol of different sets of p…
Investigating occupational well-being and leadership from a person-centred longitudinal approach: congruence of well-being and perceived leadership
2015
The overall objective of this longitudinal study was to investigate the association between perceived leadership and employee well-being from a person-centred approach utilizing the principles of the conservation of resources theory (Hobfoll, S. E. (1989). Conservation of resources: A new attempt at conceptualizing stress. American Psychologist, 44, 513–524; Hobfoll, S. E. (2002). Social and psychological resources and adaptation. Review of General Psychology, 6, 307–324). First, we aimed to identify latent classes (i.e., subgroups) of employees that demonstrated similar mean levels of stability and change in occupational well-being (i.e., vigour and emotional exhaustion) across a mean time…
Long-term profiles of work-related rumination associated with leadership, job demands, and exhaustion : A three-wave study
2017
ABSTRACTThis study extends previous research on recovery from work stress by investigating the role of qualitative job demands and leadership in employees’ work-related rumination (WRR). The long-term development of WRR was examined from a person-centred approach across 22 months. Drawing on the stressor-detachment framework and conservation of resources theory, we investigated whether different WRR profiles could be understood in terms of levels of and changes in quantitative, cognitive, and emotional job demands, several aspects of supervisory leadership, and exhaustion that was expected to result from the impeded energy restoration process. A three-wave questionnaire study was conducted …

The cardinal exercise stopper: Muscle fatigue, muscle pain or perception of effort?
2018
The capacity to sustain high-intensity aerobic exercise is essential for endurance performance. Therefore, it is important to understand what is the factor limiting time to exhaustion (TTE) in healthy and fit adults. In Study 1, maximal voluntary cycling power (MVCP) was measured in 11 volunteers before and immediately after a high-intensity TTE test on cycle ergometer. Cadence was 60 rpm in both the MVCP and TTE tests. Despite a 35% loss in MVCP, power produced during the final MVCP test (mean ± SD 469 ± 111 W) was significantly higher than the power required by the TTE test (269 ± 55 W) (P < 0.001). In Study 2, 12 participants performed a cold pressor test (CPT) to the limit of tolerance …
Inter-individual different responses to continuous and interval training in recreational middle-aged women runners
2020
A crucial subject in sports is identifying the inter-individual variation in response to training, which would allow creating individualized pre-training schedules, improving runner’s performance. We aimed to analyze heterogeneity in individual responses to two half-marathon training programs differing in running volume and intensity in middle-aged recreational women. 20 women (40 ± 7 years, 61 ± 7 kg, 167 ± 6 cm, and VO2max = 48 ± 6 mL⋅kg–1⋅min–1) underwent either moderate-intensity continuous (MICT) or high-intensity interval (HIIT) 12-week training. They were evaluated before and after training with maximal incremental tests in the laboratory (VO2max) and in the field (time to exhaustion…
