Metabolic response to 6-week aerobic exercise training and dieting in previously sedentary overweight and obese pre-menopausal women: A randomized trial

BackgroundThe aim of this study was to compare 6 weeks short-term moderate intensity aerobic exercise and dieting on serum metabolomics and cardio-metabolic risk factors in pre-menopausal women.MethodsNinety previously inactive overweight and obese (BMI 25–35 kg/m²) women (age 41.5 ± 7.6 years) were randomized to either a 6-week Nordic walking exercise program (EX, n = 45) or dietary counseling group (DI, n = 45). Body composition, serum glucose, insulin and lipids were measured. Serum low-molecular-weight metabolites and lipid constituents were analyzed by nuclear magnetic resonance spectroscopy. Measurements were done at baseline and 7 days after the last training session.ResultsSix weeks aerobic exercise program yielded reductions in serum free fatty acids (−34.7%, 95% confidence interval (CI), −50 to −18, p < 0.001), glucose (−9.6%, 95%CI, −15 to −4, p < 0.001) and homeostasis model assessment of insulin resistance (HOMA-IR) (−28.7%, 95%CI, −48 to −10, p = 0.005) without changes in body weight or fat mass. Diet counseling resulted in loss of body weight (1.5%, 95%CI, −2.3 to −0.7, p = 0.001) but no changes in free fatty acids, fasting glucose, or HOMA-IR were found.ConclusionOur results indicate that small weight loss does not produce measurable health benefits, whereas short-term regular aerobic exercise can improve glucose and lipid metabolism even in the absence of weight loss in previously sedentary overweight and obese women.

Narratives about the Media,Diet, and Body Image: A Cross-Cultural Comparison between Young Female Adults in the Midwestern United States and South Korea

This paper focuses on analysing college women’s narratives to discover their interpretations of thin ideals and dieting experiences and to compare cultural differences between the USA and Korea. Narrative analysis revealed that US women and Korean women have a different understanding of thin ideals. Both groups experienced social comparisons, social pressure to be thin, and emotional distress regarding appearance. Similarly, they revealed their emotional fluctuations associated with changes in weight. However, there were cultural differences in both groups’ ultimate goals for weight control. Consequently, this study suggests that feelings towards weight control have culturally grounded implications. Future directions are discussed.

Understanding the effects of a social media service failure apology: A comparative study of customers vs. potential customers

Service failure apologies on social media are a new crisis communication outlet trend used by companies to apologise to affected customers quickly and offer solutions, ultimately to restore customers' trust and brand loyalty. This paper contributes to the nascent literature on companies' social media service failure apologies and fills a gap in the social commerce literature by recognising that due to the open and public nature of social media, these apologies may reach not just affected customers, but also unintended audiences such as potential customers among the general public, which could potentially damage a company's reputation and market share. An online survey administered to 241 customers and 271 non-customers of a famous mobile phone brand, which used YouTube to apologise to its customers for a service failure incident, is used to explore potential behavioural outcomes, after exposure to the apology. Findings confirm that both customers and non-customers of the service provider may become exposed to a social media service failure apology. The hypothesised model predicts behavioural intentions to remain a customer after exposure to the social media service apology better than behavioural intentions to become a customer, even though relationships hold for both groups. Theoretical and managerial implications are discussed.
