#Hyperglycaemia is associated with impaired muscle signalling and #aerobic adaptation to exercise

Increased aerobic exercise capacity, as a result of exercise training, has important health benefits. However, some individuals are resistant to improvements in exercise capacity, probably due to undetermined genetic and environmental factors. Here, we show that exercise-induced improvements in aerobic capacity are blunted and aerobic remodelling of skeletal muscle is impaired in several animal models associated with chronic hyperglycaemia. Our data point to chronic hyperglycaemia … Continue reading #Hyperglycaemia is associated with impaired muscle signalling and #aerobic adaptation to exercise

Does adequate physical activity attenuate the associations of alcohol and alcohol‐related cancer mortality? A pooled study of 54 686 British adults

The potential of physical activity (PA) to attenuate the effects of alcohol consumption on the risks of alcohol‐related cancer mortality is unknown. We used data from participants aged 30 years and over in 10 British population‐based surveys (Health Surveys for England 1994, 1997, 1998, 1999, 2003, 2004, 2006 and 2008 and the Scottish Health Surveys 1998 and 2003). Alcohol‐related cancer mortality included oral cavity, throat, larynx, … Continue reading Does adequate physical activity attenuate the associations of alcohol and alcohol‐related cancer mortality?

Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal

Studies show that a single bout of exercise confers cognitive benefits. However, many individuals use psychoactive substances such as caffeine to enhance cognitive performance.. The objectives of this study were to compare the effects of acute moderate intensity aerobic exercise to caffeine on working memory (WM) and caffeine withdrawal symptoms (CWS). In Phase I, non-caffeine (n = 29) and caffeine consumers (n = 30) completed a WM assessment, followed … Continue reading Effects of #Caffeine and Acute Aerobic #Exercise on Working Memory and Caffeine Withdrawal

Lipid metabolism links nutrient-exercise timing to insulin sensitivity in men classified as overweight or #obese

Pre-exercise nutrient availability alters acute metabolic responses to exercise, which could modulate training responsiveness ..exercise before versus after breakfast consumption increased net intramuscular lipid utilization in type I (net change: -3.44±2.63% versus 1.44±4.18% area lipid staining, p < 0.01) and type II fibres (-1.89±2.48% versus 1.83±1.92% area lipid staining, p < 0.05). Training Study – postprandial glycemia was not differentially affected by 6-weeks of exercise … Continue reading Lipid metabolism links nutrient-exercise timing to insulin sensitivity in men classified as overweight or #obese

Nonpharmacological Interventions to Manage #Dementia Symptoms in Community-Dwelling Older Adults: A Cluster Randomized Controlled Trial

..exploring the effects of chair yoga (CY), compared to music intervention (MI) and chair-based exercise (CBE) in this population. Using a cluster randomized controlled trial (RCT), 3 community sites were randomly assigned 1:1:1 to CY, MI, or CBE. Participants attended twice-weekly 45-minute sessions for 12 weeks.. The CY group improved significantly in quality of life compared to the MI group .. However, no significant group … Continue reading Nonpharmacological Interventions to Manage #Dementia Symptoms in Community-Dwelling Older Adults: A Cluster Randomized Controlled Trial
