Euterpe oleracea Mart. (Açai) seed extract improves physical performance in old rats by restoring vascular function and oxidative status and activating mitochondrial muscle biogenesis.

Objectives: Alterations in cardiovascular and skeletal muscle function are hallmarks of ageing that lead to exercise intolerance. We aimed to examine whether the treatment with Euterpe oleracea Mart. seed extract (ASE) associated with exercise training improves aerobic exercise performance by promoting healthy ageing in the elderly.

Açaí (Euterpe oleracea Mart.) seed extract improves aerobic exercise performance in rats.

The purpose of this study was to examine whether the supplementation with an açai (Euterpe oleracea Mart.) seed extract (ASE) would affect the aerobic exercise performance in rats and correlate with the vascular function, muscle oxidative stress and mitochondrial biogenesis. Male Wistar rats were divided into five groups: Sedentary, Sedentary with chronic supplementation of ASE, Training, Training with chronic (200 mg/Kg/day intragastric gavage for 5 weeks) or acute (30 min before the maximal treadmill stress test (MST) supplementation with ASE.

Açaí seed extract prevents the renin-angiotensin system activation, oxidative stress and inflammation in white adipose tissue of high-fat diet-fed mice.

The role of the renin-angiotensin system (RAS), oxidative stress, and inflammation on the development of obesity and its comorbidities has been extensively addressed. Euterpe oleracea Mart. (açaí) seed extract (ASE), with antioxidant and anti-inflammatory properties and capable to modulate plasma renin levels, has been evidenced as a potential regulator of body mass.
