AIMTo investigate changes in dietary intake following a 6-mo randomised controlled trial of the self-directed, gender-tailored type 2 diabetes mellitus (T2DM) Prevention Using LifeStyle Education (PULSE) program in men. METHODSMen aged 18-65 years, with a body mass index (BMI) 25-40 kg/m2, and at high risk for developing T2DM were recruited from the Hunter Region of New South Wales, Australia. Eligible participants were randomised into one of two groups: (1) waitlist control; or (2) PULSE intervention. Dietary intake was assessed at baseline and immediately post-program using the Australian Eating Survey food frequency questionnaire and diet quality measured using the Australian Recommended Food Score (ARFS). RESULTSOne hundred and one participants (n = 48, control; n = 53, intervention, mean age 52.3 ± 9.7 years, BMI of 32.6 ± 3.3 kg/m2) commenced the study. Following the active phase, differences between groups were observed for proportion of total energy consumed from healthful (core) foods (+7.6%EI, P nutrition messages led to significant improvements in dietary intake in men at risk of T2DM.

Effect of different intensities of physical activity on cardiometabolic markers and vascular and cardiac function in adult rats fed with a high-fat high-carbohydrate diet

Journal of Sport and Health Science 2018年第1期7卷 109-119页

作者： Romeo B.Batacan Jr Mitch J.Duncan Vincent J.Dalbo Geraldine L.Buitrago Andrew S.Fenning School of Medical and Applied Sciences Central Queensland University centre for physical activity Studies Central Queensland University School of Medicine & Public Health Priority Research Centre for Physical Activity and Nutrition Faculty of Health and MedicineThe University of Newcastle University Drive Clinical Biochemistry Laboratory Central Queensland University centre for Biodiscovery and Molecular Development of Therapeutics Australian Institute of Tropical Health and MedicineJames Cook University

Background: physical activity(PA) and diet are 2 lifestyle factors that affect cardiometabolic risk. However, data on how a high-fat highcarbohydrate(HFHC) diet influences the effect of different intensities of PA on cardiometabolic health and cardiovascular function in a controlled setting are yet to be fully established. This study investigated the effect of sedentary behavior, light-intensity training(LIT), and high-intensity interval training(HIIT) on cardiometabolic markers and vascular and cardiac function in HFHC-fed adult ***: Twelve-week-old Wistar rats were randomly allocated to 4 groups(12 rats/group): control(CTL), sedentary(SED), LIT, and *** indices, glucose and lipid control, inflammatory and oxidative stress markers, vascular reactivity, and cardiac electrophysiology of the experimental groups were examined after 12 weeks of HFHC-diet feeding and PA ***: The SED group had slower cardiac conduction(p = 0.0426) and greater thoracic aortic contractile responses(p < 0.05) compared with the CTL group. The LIT group showed improved cardiac conduction compared with the SED group(p = 0.0003), and the HIIT group showed decreased mesenteric artery contractile responses compared with all other groups and improved endothelium-dependent mesenteric artery relaxation compared with the LIT group(both p < 0.05). The LIT and HIIT groups had lower visceral(p = 0.0057 for LIT, p = 0.0120 for HIIT)and epididymal fat(p < 0.0001 for LIT, p = 0.0002 for HIIT) compared with the CTL ***: LIT induced positive adaptations on fat accumulation and cardiac conduction, and HIIT induced a positive effect on fat accumulation,mesenteric artery contraction, and endothelium-dependent relaxation. No other differences were observed between groups. These findings suggest that few positive health effects can be achieved through LIT and HIIT when consuming a chronic and sustained HFHC diet.

Background: The use of nutritional supplements(NS) among athletes is widespread. However, little is known about the relationship between nutritional adequacy and NS usage. The aims of this study were to evaluate the NS usage and to compare the nutritional intake from food and prevalence of micronutrient inadequacy(PMI) between NS users and ***: Portuguese athletes from 13 sports completed an NS usage questionnaire and a semi-quantitative food-frequency questionnaire assessing information over the previous 12 months. The estimated average requirement cut-point method was used to calculate PMI. General linear models were used to compare nutritional intake and NS usage. Chi-squared tests and logistic regression were performed to study, respectively,relationships and associations between PMI and NS ***: From the 244 athletes(66% males, 13–37 years), 64% reported NS usage. After adjustment, NS users showed a higher intake from food(p nutritional intake from food, and a lower PMI for several nutrients. Perhaps, those who were taking NS were probably the ones who would least benefit from it.
