It has been well-documented that female and male athletes differ in many physiological and psychological characteristics related to endurance performance. This sex-based difference appears to be associated with their nutritional demands including the patterns of supplement intake. However, there is a paucity of research addressing the sex differences in supplement intake amongst distance runners. The present study aimed to investigate and compare supplement intake between female and male distance runners (10 km, half-marathon, (ultra-)marathon) and the potential associations with diet type and race distance. A total of 317 runners participated in an online survey, and 220 distance runners (127 females and 93 males) made up the final sample after a multi-stage data clearance. Participants were also assigned to dietary (omnivorous, vegetarian, vegan) and race distance (10-km, half-marathon, marathon/ultra-marathon) subgroups. Sociodemographic characteristics and the patterns of supplement intake including type, frequency, dosage, and brands were collected using a questionnaire. One-way ANOVA and logistic regression were used for data analysis. A total of 54.3% of female runners and 47.3% male runners reported consuming supplements regularly. The frequency of supplement intake was similar between females and males (generally or across dietary and distance subgroups). There was no significant relationship for sex alone or sex interactions with diet type and race distance on supplement intake (p < 0.05). However, a non-significant higher intake of vitamin and mineral (but not CHO/protein) supplements was reported by vegan and vegetarian (but not by omnivorous) females compared to their male counterparts. In summary, despite the reported findings, sex could not be considered as a strong modulator of supplement intake among different groups of endurance runners.

Supplement Intake

Nutrient deficiency is a common cause of underperformance in endurance athletes, and supplement intake is frequently considered compensatory for vegan and vegetarian athletes specifically. This study aimed to investigate the patterns of supplement intake among vegan, vegetarian, and omnivorous distance (>10 km) runners and its association with age, sex, and race distance. From a total of 317 runners who participated in an online survey, 220 distance runners (mean age: 38.5 years; mean BMI: 21.75 kg/m2) were selected for the final sample after data clearance and assigned to 100 omnivores, 40 vegetarians, or 80 vegans. Sociodemographic information, racing experience, and patterns of supplement intake, including type, frequency, dosage, etc., were collected using a questionnaire. Macronutrient intake was assessed using a food frequency questionnaire. ANOVA and logistic regression were used for data analysis. The prevalence of supplement intake was 51% for total runners and 72% among vegan runners. Age, sex, and race distance had no significant effect on the type of supplement intake (p > 0.05). Compared to omnivores and vegetarians, vegan runners reported consuming more vitamin (but not carbohydrate/protein or mineral) supplements (p < 0.05). Vitamin B12, magnesium, and multivitamin had the most prevalent use amongst micronutrient supplements. This study points to a central role for supplementary nutritional strategies in different groups of distance runners. The present findings may help future investigations by design to identify specific requirements of endurance runners when adhering to specific kinds of diet particularly plant-based diets.

Supplement Intake

AbstractThe primary nutritional challenge facing endurance runners is meeting the nutrient requirements necessary to optimize the performance and recovery of prolonged training sessions. Supplement intake is a commonly used strategy by elite and recreational distance runners to meet nutritional recommendations. This study was conducted to investigate the patterns of supplement intake among different groups of distance runners and the potential association between supplement intake and sex, age, running and racing experiences.In a cross-sectional design, from a total of 317 runners participating in this survey, 119 distance runners were involved in the final sample after data clearance, assigned into three groups of 10-km runners (n = 24), half-marathoners (n = 44), and (ultra-)marathoners (n = 51). Personal characteristics, training and racing experiences, as well as patterns of supplement intake, including type, frequency, and dosage, were evaluated by questionnaire. Food Frequency Questionnaire was implemented to assess macronutrient intake. ANOVA and logistic regression were used for statistical analysis.While 50 % of total distance runners reported consuming supplements regularly, no differences between distance groups in consumption of carbohydrate/protein, mineral, or vitamin supplements were observed (p > 0.05). In addition, age, sex, running and racing experience showed no significant association with supplement intake (p > 0.05). Vitamin supplements had the highest intake rate in runners by 43 % compared to minerals (34 %) and carbohydrate/protein supplements (19 %).The present findings provide a window into the targeted approaches of long-distance runners as well as their coaches and sport nutrition specialists when applying and suggesting sustainable nutritional strategies for training and competition.Trial registration: ISRCTN73074080.

ObjectiveTo describe the Australian adult public’s knowledge and experiences regarding substitute decision-making for medical decisions and their preferences for obtaining information about the substitute decision-maker (SDM) role.MethodsThis is a national cross-sectional online survey of the Australian adult public. The survey examined participants’ advance care planning (ACP) awareness and experience, SDM experiences and preferences for obtaining more information about SDM, and participant knowledge about SDM.ResultsOf 1586 people who opened the survey, 1120 (70.6%) were included in the final sample. 13% (n=142) of participants indicated they had acted as an SDM. A median score of two correct responses out of five showed low to moderate knowledge about the SDM role among all participants, with only 33% reporting awareness of SDM laws existing in Australia. While most (59%) participants ranked a health professional as their preferred source of obtaining information about supporting SDMs, few participants who had been an SDM (n=64, 45%) reported obtaining any support in making medical decisions. The median SDM knowledge scores for people who had discussed ACP (3.0 vs 2.0, U=1 45 222, z=6.910, p<0.001), documented their ACP preferences (3.0 vs 2.0, U=71 984, z=4.087, p<0.001) or acted in the SDM role (3.0 vs 2.0, U=56 353, z=−3.694, p<0.001) were significantly higher compared with those who had not.ConclusionsThe Australian public may have low to moderate knowledge about the SDM role and access only minimal support when making challenging medical decisions.

[U25] is a German online-peer-counseling service for adolescents with suicidal ideation, who typically do not seek or receive adequate counseling. We conducted an online survey in order to compare persons who receive online counseling by [U25] compared to those who are visitors of [U25] websites but do not (yet) receive counseling. Via online survey, all visitors to the [U25] websites were invited to fill in a questionnaire on sociodemographic data, utilization reasons, and barriers. Our final sample consisted of n = 318 counseling clients, n = 1127 persons who have not yet sought help but intend to do so (“prospective clients”), and n = 444 persons who do not consider [U25] counseling for themselves (“refusers”). Clients were more often female and showed positive attitudes toward online counseling. Low perceived need for counseling was the most frequent barrier reported by the refusers, whereas fear of stigma and practical barriers were rarely reported; younger and male refusers reported needing to write down one’s problems as a barrier more often. Self-selection might reduce generalizability of our results. Online counseling can facilitate receiving psychosocial support for young persons with suicidal ideation, particularly if barriers are addressed.

PURPOSE: Trust is vital to all positive relationships. This empirical study explores the effect of three facets of organisational trust (trust in supervisors, in co-workers and in the organisation) on employee commitment in Salalah Mills Co. in the food industry in the Sultanate of Oman. METHODOLOGY: Data were collected via an online survey sent to all employees working in Salalah Mills Co., Oman. The final sample consisting of 102 responses with a response rate of 54 percent were analysed using multiple regression analysis. RESULTS: The findings revealed that two facets of organisational trust (trust in co-workers and trust in supervisors) were found to have a significant positive effect on employee commitment, while trust in the organisation was found to have no significant effect. PRACTICAL IMPLICATIONS: Trust in supervisors and trust in co-workers directly affect employee commitment. Therefore, managers should consider promoting both of these forms of trust to enhance employee commitment. VALUE: Although previous studies have examined the link between organisational trust and employee commitment, a focus on Oman and the food sector has been particularly rare, so this study offers new insights. The findings will help decision-makers on design strategies and policies to improve employee commitment through trust.

Regular physical exercise and a healthy diet are major determinants of a healthy lifespan. Although aging is associated with declining endurance performance and muscle function, these components can favorably be modified by regular physical activity and especially by exercise training at all ages in both sexes. In addition, age-related changes in body composition and metabolism, which affect even highly trained masters athletes, can in part be compensated for by higher exercise metabolic efficiency in active individuals. Accordingly, masters athletes are often considered as a role model for healthy aging and their physical capacities are an impressive example of what is possible in aging individuals. In the present review, we first discuss physiological changes, performance and trainability of older athletes with a focus on sex differences. Second, we describe the most important hormonal alterations occurring during aging pertaining regulation of appetite, glucose homeostasis and energy expenditure and the modulatory role of exercise training. The third part highlights nutritional aspects that may support health and physical performance for older athletes. Key nutrition-related concerns include the need for adequate energy and protein intake for preventing low bone and muscle mass and a higher demand for specific nutrients (e.g., vitamin D and probiotics) that may reduce the infection burden in masters athletes. Fourth, we present important research findings on the association between exercise, nutrition and the microbiota, which represents a rapidly developing field in sports nutrition.

Purpose Information sharing is vital to organizational operations, yet employees are often reluctant to share negative information. This paper aims to gain insight into which employees will be reluctant to share negative information and when by drawing from the proactive motivation literature examining effects of proactive personality and motivational states on individuals’ willingness to share negative information. Design/methodology/approach A cross-sectional design was used, with data collected from a final sample of 393 individuals via an online survey. Hypotheses were tested using correlation and hierarchical multiple regression analyses. Findings Interactive effects indicate proactive individuals with accompanying high levels of role breadth self-efficacy (“can do”) or high levels of felt responsibility for constructive change (“reason to”) were less likely to be reluctant to share negative information. However, findings also suggest proactive individuals with lower levels of proactive motivation avoid sharing negative information. Originality/value The findings extend what is known about personality factors and employee willingness to share information to highlight which employees may be likely to avoid sharing negative information. The authors also examine the moderating influence of proactive motivational states on the relationships between proactive personality and reluctance to share negative information.

ObjectiveHow adverse outcomes and complaints are managed may significantly impact on physician well-being and practice. We aimed to investigate how depression, anxiety and defensive medical practice are associated with doctors actual and perceived support, behaviour of colleagues and process issues regarding how complaints investigations are carried out.DesignA survey study. Respondents were classified into three groups: no complaint, recent/current complaint (within 6 months) or past complaint. Each group completed specific surveys.SettingBritish Medical Association (BMA) members were invited to complete an online survey.Participants95 636 members of the BMA were asked to participate. 7926 (8.3%) completed the survey, of whom 1780 (22.5%) had no complaint, 3889 (49.1%) had a past complaint and 2257 (28.5%) had a recent/current complaint. We excluded those with no complaints leaving 6144 in the final sample.Primary outcomes measuresWe measured anxiety and depression using the Generalised Anxiety Disorder Scale 7 and Physical Health Questionnaire 9. Defensive practice was assessed using a new measure for avoidance and hedging.ResultsMost felt supported by colleagues (61%), only 31% felt supported by management. Not following process (56%), protracted timescales (78%), vexatious complaints (49%), feeling bullied (39%) or victimised for whistleblowing (20%), and using complaints to undermine (31%) were reported. Perceived support by management (relative risk (RR) depression: 0.77, 95% CI 0.71 to 0.83; RR anxiety: 0.80, 95% CI 0.74 to 0.87), speaking to colleagues (RR depression: 0.64, 95% CI 0.48 to 0.84 and RR anxiety: 0.69, 95% CI 0.51 to 0.94, respectively), fair/accurate documentation (RR depression: 0.80, 95% CI 0.75 to 0.86; RR anxiety: 0.81, 95% CI 0.75 to 0.87), and being informed about rights (RR depression 0.96 (0.89 to 1.03) and anxiety 0.94 (0.87 to 1.02), correlated positively with well-being and reduced defensive practice. Doctors worried most about professional humiliation following a complaint investigation (80%).ConclusionPoor process, prolonged timescales and vexatious use of complaints systems are associated with decreased psychological welfare and increased defensive practice. In contrast, perceived support from colleagues and management is associated with a reduction in these effects.

Background: Protein supplements have become a widespread practice amongst athletes and gym users worldwide. However, studies on the use of protein supplements among female gym users in Saudi Arabia are lacking. Objective: The aim of this study was to investigate the prevalence of protein supplement usage among female gym users and their attitudes towards protein supplementation in Riyadh city, Saudi Arabia. Methods: In this cross-sectional study, 502 female gym users aged ≥18 years completed a structured, self-administered online questionnaire on the usage of protein supplementation. Socio-demographic information, anthropometry, health status, exercise frequency, attitudes and knowledge regarding protein supplements were obtained. Results: The overall prevalence rate of protein supplement use among the study respondents was 36.3%. There were significant associations between the use of protein supplements and educational level (p< 0.05), the duration of being a gym member (p< 0.05) and frequency of gym visits per week (p< 0.05). Whey protein was the predominantly used supplement (57.8%), and the reason attributed to the use of protein supplement was muscle building (53.9%). The main sources of information regarding protein supplement use included the internet (30.2%) followed by gym coaches (25.3%). Conclusion: Our findings demonstrated that a considerable number of females exercising in gyms use protein supplements, and most rely on unreliable sources for decision-making of protein supplements use. Nutritional education and consultations regarding protein supplement use are warranted.

Selective pressures throughout evolutionary history have caused the adaptation of sex-specific responses to dilemmas that are relevant for reproductive fitness. Sex differences in imagined jealousy due to infidelity are well documented, but past work does not consider the influence of reproductive capability (i.e., being fertile versus infertile) on responses. Relying on an online survey of 369 adults, we hypothesized that infidelities involving an infertile interloper lead to less jealousy than infidelities involving a fertile interloper. Further, for sexual infidelity, regardless of the interloper’s fertility, we hypothesized men would allocate the most responsibility to their partner and women would do so for the interloper, given women are assumed to behave with more intention. This hypothesis was partially supported; while men did allocate the most responsibility to their mate, so too did women, but women also blamed the interloper more than men. With regards to emotional infidelity, again independent of the interloper’s fertility, we hypothesized men will primarily hold their partner responsible. However, we hypothesized that women will again consider the interloper responsible, but also their partner, due to concerns over fear of losing access to needed resources. This prediction was partially supported, as both sexes primarily hold their partner most responsible, and women held the interloper more accountable than did men. The findings shed light onto how individuals assess relationship threats and allocate responsibility, according to reproductive capability.
