The efficacy of #exergaming in people with major #neurocognitive disorder residing in long-term care facilities: a pilot randomized controlled trial

It is currently unknown whether exergaming is efficacious in people with major neurocognitive disorder (MNCD) residing in long-term care facilities. This pilot randomized controlled trial (RCT) explored the efficacy of a stepping exergame program on gait speed, balance, mobility, reaction time, cognitive and neuropsychiatric outcomes, quality of life, and daily life functioning in people with MNCD residing in long-term care facilities. Methods Participants were randomly … Continue reading The efficacy of #exergaming in people with major #neurocognitive disorder residing in long-term care facilities: a pilot randomized controlled trial

#Caffeine increases maximal #fat oxidation during a graded exercise test: is there a diurnal variation?

There is evidence that caffeine increases the maximal fat oxidation rate (MFO) and aerobic capacity, which are known to be lower in the morning than in the afternoon. This paper examines the effect of caffeine intake on the diurnal variation of MFO during a graded exercise test in active men. Methods Using a triple-blind, placebo-controlled, crossover experimental design, 15 active caffeine-naïve men (age: 32 ± 7 years) completed … Continue reading #Caffeine increases maximal #fat oxidation during a graded exercise test: is there a diurnal variation?

OR10-1 – Efficacy of High-Intensity Intermittent #Training for Improving Cardio-Metabolic Health in Women With #Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with significant metabolic and reproductive manifestations, carrying a major health and economic burden. Consistent improvements in clinical outcomes have been reported as a result of exercise training, but shortfalls with exercise prescription are evident. Research suggests that high-intensity intermittent training (HIIT) is feasible, well tolerated and enjoyable for people with or at risk of chronic … Continue reading OR10-1 – Efficacy of High-Intensity Intermittent #Training for Improving Cardio-Metabolic Health in Women With #Polycystic Ovary Syndrome

Long-term risk of #stroke and myocardial #infarction in middle-aged men with a #hypertensive response to exercise: a 44-year follow-up study

Data on the prognostic value of hypertensive response to exercise in cardiovascular disease are limited. The aim was to determine whether SBP reactions during exercise have any prognostic value in relation to the long-term risk of stroke and myocardial infarction (MI). Patients and methods: A representative cohort of men from Gothenburg, Sweden, born in 1913, who performed a maximum exercise test at age 54 years, … Continue reading Long-term risk of #stroke and myocardial #infarction in middle-aged men with a #hypertensive response to exercise: a 44-year follow-up study

Dynamic changes in DICER levels in #adipose tissue control metabolic adaptations to #exercise

DICER is a key enzyme in microRNA (miRNA) biogenesis. Here we show that aerobic exercise training up-regulates DICER in adipose tissue of mice and humans. This can be mimicked by infusion of serum from exercised mice into sedentary mice and depends on AMPK-mediated signaling in both muscle and adipocytes. Adipocyte DICER is required for whole-body metabolic adaptations to aerobic exercise training, in part, by allowing … Continue reading Dynamic changes in DICER levels in #adipose tissue control metabolic adaptations to #exercise

Metabolic Architecture of Acute #Exercise Response in Middle-Aged Adults in the Community

Whereas regular exercise is associated with lower risk of cardiovascular disease and mortality, mechanisms of exercise-mediated health benefits remain less clear. We used metabolite profiling before and after acute exercise to delineate the metabolic architecture of exercise response patterns in humans.. ..We observed changes in circulating levels for 502 of 588 measured metabolites from rest to peak exercise (exercise duration 11.9±2.1 minutes) at a 5% … Continue reading Metabolic Architecture of Acute #Exercise Response in Middle-Aged Adults in the Community

Effect of time of day of recreational and household #physical activity on prostate and breast #cancer risk (MCC‐Spain study)

Experimental evidence indicates that exercise performed at different times of the day may affect circadian rhythms and circadian disruption has been linked to breast and prostate cancer. We examined in a population‐based case‐control study (MCC‐Spain) if the time‐of‐day when physical activity is done affects prostate and breast cancer risk. Lifetime recreational and household physical activity was assessed by in‐person interviews. Information on time‐of‐day of activity … Continue reading Effect of time of day of recreational and household #physical activity on prostate and breast #cancer risk (MCC‐Spain study)

#Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress

Key points In humans, hypohydration attenuates sweat secretion and attenuates whole‐body heat loss, probably to mitigate further fluid losses and thereby support blood pressure regulation. Recently, however, we demonstrated that the hypohydration‐mediated reduction in net whole‐body heat exchange (evaporative heat loss – dry heat gain) was blunted in middle‐aged compared to younger men during moderate exercise in dry heat; albeit, the underpinning mechanisms could not … Continue reading #Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress

#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

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).
