OBJECTIVE We aimed to determine the association of time-of-day bout-related moderate-to-vigorous physical activity (bMVPA) with changes in glycemic control across 4 years adults overweight/obesity and type 2 diabetes. RESEARCH DESIGN AND METHODS Among 2,416 participants (57% women; mean age, 59 years) 7-day waist-worn accelerometry recording at year 1 or 4, we assigned bMVPA timing groups based on participants’ temporal distribution recategorized them 4. The time-varying exposure (≥10-min bout) was defined as ≥50% occurring during same time period (morning, midday, afternoon, evening), <50% any (mixed), ≤1 day per week (inactive). RESULTS HbA1c reduction varied among (P = 0.02), independent weekly volume intensity. afternoon group had greatest versus inactive (−0.22% [95%CI −0.39%, −0.06%]), magnitude which 30–50% larger than other groups. odds discontinuation maintaining initiating glucose-lowering medications differed by 0.04). highest (odds ratio 2.13 [95% CI 1.29, 3.52]). For all year-4 groups, there were no significant between CONCLUSIONS performed is associated improvements diabetes, especially within initial 12 months an intervention. Experimental studies are needed examine causality.

Circadian rhythms evolved through adaptation to daily light/dark changes in the environment; they are believed be regulated by core circadian clock interlocking feedback loop. Recent studies indicate that each component executes general and specific functions metabolism. Here, we review current understanding of role these genes regulation metabolism using various genetically modified animal models. Additionally, emerging evidence shows exposure environmental stimuli, such as artificial light, unbalanced diet, mistimed eating, exercise, remodels physiological processes causes metabolic disorders. This Review summarizes reciprocal between metabolism, highlights remaining gaps knowledge about examines potential applications human health disease.

Circadian clocks are biological timing mechanisms that generate 24-h rhythms of physiology and behavior, exemplified by cycles sleep/wake, hormone release, metabolism. The adaptive value is evident when internal body daily environmental mismatched, such as in the case shift work jet lag or even mistimed eating, all which associated with physiological disruption disease. Studies animal human models have also unraveled an important role functional circadian modulating cellular organismal responses to cues (ex., food intake, exercise), pathological insults (e.g. virus parasite infections), medical interventions medication). With growing knowledge molecular underlying pathophysiology, it becoming possible target for disease prevention treatment. In this review, we discuss recent advances research potential therapeutic applications take patient into account treating

The circadian clock and metabolism are tightly intertwined. Hence, the specific timing of interventions that target metabolic changes may affect their efficacy. Here we retrospectively compared health effects morning versus afternoon exercise training in metabolically compromised subjects enrolled a 12-week program. Thirty-two adult males (58 ± 7 yrs) at risk for or diagnosed with type 2 diabetes performed 12 weeks supervised either (8.00-10.00 a.m., N = 12) (3.00-6.00 p.m., 20). Compared to participants who trained morning, experienced superior beneficial on peripheral insulin sensitivity (+5.2 6.4 vs. -0.5 5.4 μmol/min/kgFFM, p .03), insulin-mediated suppression adipose tissue lipolysis (-4.5 13.7% +5.9 11%, .04), fasting plasma glucose levels (-0.3 1.0 +0.5 0.8 mmol/l, .02), performance (+0.40 0.2 +0.2 0.1 W/kg, .05) fat mass (-1.2 1.3 -0.2 kg, .03). In addition, also tended elicit basal hepatic output (p .057). Our findings suggest reap more pronounced benefits from when this is morning. CLINICALTRIALS.GOV ID: NCT01317576.

Abstract Obesity and type 2 diabetes (T2D) have become a global health concern. The prevalence of obesity T2D is significantly higher in shift workers compared to people working regular hours.

Abstract Aims/hypothesis We determined whether the time of day exercise training (morning vs evening) would modulate effects consumption a high-fat diet (HFD) on glycaemic control, whole-body health markers and serum metabolomics. Methods In this three-armed parallel-group randomised trial undertaken at university in Melbourne, Australia, overweight/obese men consumed an HFD (65% energy from fat) for 11 consecutive days. Participants were recruited via social media community advertisements. Eligibility criteria participation male sex, age 30–45 years, BMI 27.0–35.0 kg/m 2 sedentary lifestyle. The main exclusion known CVD or type diabetes, taking prescription medications, shift-work. After 5 days, participants allocated using computer random generator to either morning (06:30 hours), evening (18:30 hours) no subsequent researchers not blinded group assignment. Changes metabolites, circulating lipids, cardiorespiratory fitness, BP, control (from continuous glucose monitoring) compared between groups. Results Twenty-five n = 9; 8; 8) 24 completed study included analyses ( 8 per group). Five days induced marked perturbations metabolites related lipid amino acid metabolism. Exercise had smaller impact than changes only was able partly reverse some HFD-induced metabolomic profiles. Twenty-four-hour concentrations lower after with participants’ habitual (5.3 ± 0.4 5.6 mmol/l, p 0.001).

Skeletal muscles require the proper production and distribution of energy to sustain their work. To ensure this requirement is met, mitochondria form large networks within skeletal muscle cells, during exercise, they can enhance functions. In present review, we discuss recent findings on exercise-induced mitochondrial adaptations. We emphasize importance biogenesis, morphological changes, increases in respiratory supercomplex formation as mechanisms triggered by exercise that may increase function muscles. Finally, highlight possible effects nutraceutical compounds performance outline use a therapeutic tool noncommunicable disease prevention. The resulting picture shows modulation activity not only fundamental for physical but also key point whole-organism well-being.

Abstract The beneficial effects of physical activity on the cardiovascular system nowadays have achieved relevance clinical evidence. In fact, several studies documented benefits exercise training in prevention risk. Abnormalities insulin signaling transduction account for impairment sensitivity and development resistance, which, turn, is responsible enhancement Insulin related to degree activity, has been shown ameliorate action insulin-resistant subjects. This effect mediated by improvement molecular abnormalities that are contributing this way restore physiological sensitivity. However, it should be underlined mechanisms phenomenon extremely complex still unclear. Further required better clarify basis exercise-evoked signal.
