Project description:Since physical inactivity especially prevails during winter months, we set out to identify outdoor alternatives to indoor cycling (IC) by comparing the metabolic and cardiorespiratory responses during alpine skiing (AS), cross-country skiing (XCS) and IC and analyse the effects of sex, age and fitness level in this comparison. Twenty one healthy subjects performed alpine skiing (AS), cross-country skiing (XCS), and IC. Oxygen uptake (VO2), total energy expenditure (EE), heart rate (HR), lactate, blood glucose and rate of perceived exertion (RPE) were determined during three 4-min stages of low, moderate and high intensity. During XCS and IC VO2max and EE were higher than during AS. At least 2½ hours of AS are necessary to reach the same EE as during one hour of XCS or IC. HR, VO2, lactate, and RPEarms were highest during XCS, whereas RPEwhole-body was similar and RPElegs lower than during AS and IC, respectively. Weight adjusted VO2 and EE were higher in men than in women while fitness level had no effect. Male, fit and young participants were able to increase their EE and VO2 values more pronounced. Both AS and XCS can be individually tailored to serve as alternatives to IC and may thus help to overcome the winter activity deficit. XCS was found to be the most effective activity for generating a high EE and VO2 while AS was the most demanding activity for the legs. Key pointsDuring cross-country skiing and indoor cycling VO2max and energy expenditure were higher than during alpine skiingApproximately 2½ hours of alpine skiing are necessary to reach the same energy expenditure of one hour of cross-country skiing or indoor cycling.Alpine skiing and cross-country skiing can be individually tailored to serve as sports alternatives in winter to activity deficit.By applying different skiing modes as parallel ski steering, carving long radii and short turn skiing, metabolic and cardiorespiratory response can be increased during alpine skiing.Male, fit and young participants were able to increase their energy expenditure and VO2 more pronounced with an increase in intensity compared with their counterparts.

Project description:In this study, we analyze the free verbal associations to the stimuli women quotas and men quotas of 327 medical students. Women and men quotas are characterized by the same modus operandi (i.e., preferential treatment based on sex/gender). However, women quotas help a low-status group, whereas men quotas help a high-status group. In line with a support paradox, that is, the perception that support for women is less fair and less legitimate than support for men, we expected that students would reject women quotas in academia more vehemently than men quotas. Specifically, we hypothesized that students would have more negative and more emotional associations with women quotas than men quotas. As predicted, students had more negative associations with women quotas than with men quotas. However, students did not have more emotional associations with women quotas than with men quotas. In addition, we explored the semantic content of the free associations to identify specific concerns over each quota. Students perceived women quotas as counterproductive, derogatory, and unfair, whereas they perceived men quotas as beneficial and fair. Concerns over the negative perceptions of quota beneficiaries were associated more frequently with women quotas than men quotas. Potential factors underlying students' perceptions of both quotas are discussed.

Project description:In the present research, we applied a goal-congruity perspective - the proposition that men and women seek out roles that afford their internalized values (Diekman et al., 2017) - to better understand the degree to which careers in healthcare, early education, and domestic roles (HEED; Croft et al., 2015) are devalued in society. Our first goal was to test the hypothesis that men, relative to women, are less interested in pursuing HEED careers in part because they are less likely than women to endorse communal values. A second, more novel goal was to extend goal congruity theory to examine whether gender differences in communal values also predict the belief that HEED careers add worth to society and are deserving of higher salaries. In three studies of undergraduate students (total N = 979), we tested the predictive role of communal values (i.e., a focus on caring for others), as distinct from agentic values (i.e., a focus on status, competition, and wealth; Bakan, 1966). Consistent with goal congruity theory, Studies 1 and 2 revealed that men's lower interest in adopting HEED careers, such as nursing and elementary education, was partially mediated by men's (compared to women's) lower communal values. Extending the theory, all three studies also documented a general tendency to see HEED as having relatively lower worth to society compared to STEM careers. As expected, communal values predicted perceiving higher societal worth in HEED careers, as well as supporting increases in HEED salaries. Thus, gender differences in communal values accounted for men's (compared to women's) tendency to perceive HEED careers as having less societal worth and less deserving of salary increases. In turn, gender differences in perceived societal worth of HEED itself predicted men's relatively lower interest in pursuing HEED careers. In no instance, did agentic values better explain the gender difference in HEED interest or perceived worth. These findings have important implications for how we understand the value that society places on occupations typically occupied by women versus men.

Project description:In alpine skiing, estimation of the muscle forces and joint loads such as the forces in the ACL of the knee are essential to quantify the loading pattern of the skier during turning maneuvers. Since direct measurement of these forces is generally not feasible, non-invasive methods based on musculoskeletal modeling should be considered. In alpine skiing, however, muscle forces and ACL forces have not been analyzed during turning maneuvers due to the lack of three dimensional musculoskeletal models. In the present study, a three dimensional musculoskeletal skier model was successfully applied to track experimental data of a professional skier. During the turning maneuver, the primary activated muscles groups of the outside leg, bearing the highest loads, were the gluteus maximus, vastus lateralis as well as the medial and lateral hamstrings. The main function of these muscles was to generate the required hip extension and knee extension moments. The gluteus maximus was also the main contributor to the hip abduction moment when the hip was highly flexed. Furthermore, the lateral hamstrings and gluteus maximus contributed to the hip external rotation moment in addition to the quadratus femoris. Peak ACL forces reached 211 N on the outside leg with the main contribution in the frontal plane due to an external knee abduction moment. Sagittal plane contributions were low due to consistently high knee flexion (> 60[Formula: see text]), substantial co-activation of the hamstrings and the ground reaction force pushing the anteriorly inclined tibia backwards with respect to the femur. In conclusion, the present musculoskeletal simulation model provides a detailed insight into the loading of a skier during turning maneuvers that might be used to analyze appropriate training loads or injury risk factors such as the speed or turn radius of the skier, changes of the equipment or neuromuscular control parameters.

Project description:BackgroundNonlinear career paths are increasingly common. Women in academia pursuing nonlinear career paths experience negative impacts on career trajectory. No published studies have examined how pursuit of nonlinear career paths might perpetuate gender inequities within academic hospital medicine.Objective(1) Compare the frequency of nonlinear career paths by gender among academic hospitalists; (2) assess the perceived impact of two types of nonlinear career paths-extended leave (EL) and non-traditional work arrangements (NTWA) on hospitalists' personal lives and careers.Design, setting, and participantsCross-sectional descriptive survey study of adult hospitalist physicians in three academic centers within the USA.InterventionElectronic survey including closed- and open-ended items assessing respondent utilization of and experiences with nonlinear career paths.Main outcomes and measures(1) Associations between EL and demographic variables as well as gender differences in leave length and NTWA strategies using Fisher's exact test; 2) grounded theory qualitative analysis of open-text responses.Key resultsCompared with men, women reported taking EL more often (p = 0.035) and for longer periods (p = 0.002). Men and women reported taking NTWA at similar rates. Women reported negative impacts of EL within domains of personal life, career, well-being, and work-life integration whereas men only reported negative impacts to career. Men and women described positive impacts of NTWA across all domains.ConclusionsWomen academic hospitalists reported taking EL more often than men and experienced disproportionately more adverse impacts to personal lives and careers. Surprisingly, men reported taking NTWA to address burnout and childbirth at similar rates to women. Our findings lay the groundwork for additional exploration of cultural and policy interventions, particularly improved paid leave policies.

Project description:ObjectiveTo examine whether gender differences in primary care consultation rates (1) vary by age and deprivation status and (2) diminish when consultation for reproductive reasons or common underlying morbidities are accounted for.DesignCross-sectional study of a cohort of patients registered with general practice.SettingUK primary care.SubjectsPatients (1 869 149 men and 1 916 898 women) registered with 446 eligible practices in 2010.Primary outcome measuresPrimary care consultation rate.ResultsThis study analyses routinely collected primary care consultation data. The crude consultation rate was 32% lower in men than women. The magnitude of gender difference varied across the life course, and there was no 'excess' female consulting in early and later life. The greatest gender gap in primary care consultations was seen among those aged between 16 and 60 years. Gender differences in consulting were higher in people from more deprived areas than among those from more affluent areas. Accounting for reproductive-related consultations diminished but did not eradicate the gender gap. However, consultation rates in men and women who had comparable underlying morbidities (as assessed by receipt of medication) were similar; men in receipt of antidepressant medication were only 8% less likely to consult than women in receipt of antidepressant medication (relative risk (RR) 0.916, 95% CI 0.913 to 0.918), and men in receipt of medication to treat cardiovascular disease were just 5% less likely to consult (RR=0.950, 95% CI 0.948 to 0.952) than women receiving similar medication. These small gender differences diminished further, particularly for depression (RR=0.950, 95% CI 0.947 to 0.953), after also taking account of reproductive consultations.ConclusionsOverall gender differences in consulting are most marked between the ages of 16 and 60 years; these differences are only partially accounted for by consultations for reproductive reasons. Differences in consultation rates between men and women were largely eradicated when comparing men and women in receipt of medication for similar underlying morbidities.

Project description:To determine the hormonal effects of reducing sleep duration under controlled feeding conditions.Randomized, crossover study.Inpatient.Twenty-seven normal weight, 30- to 45-yr-old men and women habitually sleeping 7-9 hr/night.PARTICIPANTS WERE STUDIED UNDER TWO SLEEP CONDITIONS: short (4 hr in bed) or habitual (9 hr in bed) sleep. A controlled diet was provided for each 4-day study period.Fasting blood samples were obtained daily and frequent blood samples were obtained throughout day 4. The main outcomes measures included glucose, insulin, leptin, ghrelin, adiponectin, total glucagon-like peptide 1 (GLP-1) and peptide YY(3-36) (PYY(3-36)) concentrations. Body weights were reduced by 2.2 ± 0.4 lb and 1.7 ± 0.4 lb during the habitual and short sleep phases, respectively (both P < 0.0001). There was no effect of sleep duration on glucose, insulin, and leptin profiles (all P > 0.05). Ghrelin and GLP-1 responses differed by sex. Short sleep increased fasting (P = 0.054) and morning (08:00-12:00) (P = 0.042) total ghrelin in men but not women. The reverse was observed for GLP-1: afternoon levels (12:30-19:00) were lower (P = 0.016) after short sleep compared with habitual sleep in women but not men.These data suggest that, in the context of negative energy balance, short sleep does not lead to a state of increased insulin resistance, but may predispose to overeating via separate mechanisms in men and women.Trial registration on http://www.clinicaltrials.gov. #NCT00935402.

Project description:The coronavirus pandemic lockdowns have led to an increase of caregiving and household responsibilities for many employees while working from home. We aimed to investigate whether there was a gender imbalance in the division of household labour within families during the pandemic, and whether this imbalance was associated with gender differences in personal outcomes (work-family conflict, burnout) as well as career-related outcomes (career self-efficacy and aspirations). Participants were 240 heterosexual individuals with or without caregiving responsibilities who lived with a partner and worked from home during the pandemic. They completed self-report questionnaires and indicated the division of domestic tasks within their household, the extent to which they experienced burnout and work-family conflict, and their career aspirations and career self-efficacy. The findings showed a significant gender imbalance, such that female caregivers spent significantly less time on work compared to the other groups and significantly more time on caregiving compared to male caregivers during the lockdown. There was a significant direct effect of caregiving on career outcomes for women, such that the more caregiving women performed during the lockdown relative to other tasks, the more negative their self-reported career outcomes were. Among men, caregiving did not predict career outcomes. Overall, our study showed that the gender imbalance in distributions of caregiving duties during the pandemic is associated with negative personal and professional outcomes for women who are caregivers. Practical implications are discussed accounting for this gender imbalance in the context of the pandemic and its influence on wellbeing and career outcomes, particularly for heterosexual women.Supplementary informationThe online version contains supplementary material available at 10.1007/s12144-021-02630-6.

Project description:Purpose Research has shown that there are important sex and gender-based differences in the work disability duration of men and women. This research is often limited to single jurisdictions, using different outcome measures, and therefore has limited generalisability of findings. This study examined if differences between work disability of men and women differed by province and by duration of work disability. Methods Cohorts of injured workers in the Canadian provinces of British Columbia (BC), Manitoba (MB) and Ontario (ON) were analysed using workers' compensation data for work-related injuries occurring between 2007 and 2011. Work disability duration was measured using cumulative days in receipt of disability benefits paid during one-year post-injury. Poisson models with restricted cubic splines tested whether differences between men and women in the likelihood of transitioning off disability benefits varied by duration of work disability in each province, adjusting for confounders. Results Men transitioned off disability benefits faster than women for claim durations of up to two to four months, after which women transitioned off disability benefits faster until ten months. Differences between men and women were consistent across all jurisdictions. For claims longer than ten months, men transitioned off work disability benefits faster than women in BC and ON, but there were no significant differences between men and women in MB. Conclusions Differences in the work disability duration between men and women vary by province and duration of work disability. Claims management processes need to be sensitive to differences that men and women face and the timing of interventions.
