Longitudinal associations of physical activity, sedentary time, and cardiorespiratory fitness with arterial health in children–the PANIC study

We investigated the longitudinal associations of physical activity (PA), sedentary time (ST), and cardiorespiratory fitness (CRF) with arterial health among children. In our primary analyses, we investigated 245 children (girls 51.8%) aged 6-9 years participating in the baseline examinations who had data on arterial health at 2-year follow-up. We also utilized a subsample of 90 […]

Joint associations between objectively measured physical activity volume and intensity with body-fatness. The Fenland Study

Background/Objectives Physical activity energy expenditure (PAEE) represents the total volume of all physical activity. This can be accumulated as different underlying intensity profiles. Although volume and intensity have been studied in isolation, less is known about their joint association with health. We examined this association with body-fatness in a population-based sample of middle-aged British women […]

Testosterone and exercise: Effects on fitness, body composition and strength in middle-to-older aged men with low-normal serum testosterone levels

As men age, serum testosterone (T) concentrations decrease, as do fitness, strength and lean mass. Whether testosterone treatment confers additive benefit to reverse these changes when combined with exercise training in middle-to-older aged men remains unclear. We assessed the effects of T treatment and exercise, alone and in combination, on aerobic capacity (VO2peak), body composition […]

Effects of gastric bypass surgery on the brain; simultaneous assessment of glucose uptake, blood flow, neural activity and cognitive function during normo-and hypoglycemia

While Roux-en-Y Gastric Bypass (RYGB) surgery in obese individuals typically improves glycemic control and prevents diabetes, it also frequently causes hypoglycemia. Previous work showed attenuated counter-regulatory responses following RYGB. The underlying mechanisms as well as the clinical consequences are unclear.In this study, 11 non-diabetic subjects with severe obesity were investigated pre- and post-RYGB during hyperinsulinemic […]

Decreased energy availability during training overload is associated with non-functional overreaching and suppressed ovarian function in female runners

Low energy availability (EA) suppresses many physiological processes, including ovarian function in female athletes. Low EA could also predispose athletes to develop a state of overreaching. This study compared the changes in ad libitum energy intake (EI), exercise energy expenditure (ExEE), and EA among runners completing a training overload (TO) phase. We tested the hypothesis […]

β-Lactoglobulin Elevates Insulin and Glucagon Concentrations Compared with Whey Protein—A Randomized Double-Blinded Crossover Trial in Patients with Type Two Diabetes Mellitus

Whey protein is an insulinotropic fraction of dairy that reduces postprandial glucose levels in patients with type 2 diabetes mellitus (T2DM). We have recently shown that β-lactoglobulin (BLG), the largest protein fraction of whey, elevates insulin concentrations compared with iso-nitrogenous whey protein isolate (WPI) in healthy individuals. We therefore hypothesized that BLG pre-meals would lower […]
