Acute Effect of High-Intensity Interval Exercise on Blood Pressure in Females Living with Type 2 Diabetes and Hypertension.

Background : The acute effects of high-intensity interval training (HIIT) on blood pressure (BP) may depend on the exercise protocol performed. Purpose: To compare the acute effect of high and low-volume HIIT on post-exercise and ambulatory BP in untrained older females diagnosed with both type 2 diabetes (T2D) and hypertension (HTN). Methods: Fifteen females (69 [65 ─ 74] years) completed a crossover study with three experimental conditions: 1) REST (35 min in sitting position); 2) HIIT10 (10 × 1 min at 90% heart rate max [HRmax]), and 3) HIIT4 (4 × 4 min at 90% HRmax).

A multimodal neuroimaging study of youth at risk for substance use disorders: Functional magnetic resonance imaging and [F]fallypride positron emission tomography.

Background: Adolescent alcohol use is the norm, but only some develop a substance use disorder. The increased risk might reflect heightened mesocorticolimbic responses to reward-related cues but results published to date have been inconsistent.

Methods: Young social drinkers (age 18.

An acute bout of 4 × 4-min or 10 × 1-min HIIT improves β cell glucose sensitivity in postmenopausal females with type 2 diabetes: a secondary analysis.

Improvements in glycemic control following acute exercise are typically attributed to improved postexercise insulin sensitivity (IS) with comparatively little known about how acute exercise impacts β cell function, especially in postmenopausal females. We determined how two high-intensity interval training (HIIT) protocols, matched for total estimated energy expenditure, impact β cell function in postmenopausal females with type 2 diabetes. Thirteen postmenopausal females (70 ± 5 yr; 12 ± 7 yr since diagnosis, 80.

Understanding Early Risk Factors of Preschool Disruptive Behaviors in a Population-Based Birth Cohort: Why Does Comorbidity Matter?

Background/objectives: Research on early risk factors for disruptive behaviors (DBs: hyperactivity-impulsivity/HI, non-compliance/NC, or physical aggression/PA) has predominantly focused on individual DBs in silos (i.e., HI, NC, PA) or the broader category of externalizing, reporting mostly common risk factors among them.
