Avocado (Persea americana) pulp improves cardiovascular and autonomic recovery following submaximal running: a crossover, randomized, double-blind and placebo-controlled trial

Abstract

previous studies have demonstrated that regular avocado consumption presents advantageous effects on cardiovascular system. However, little attention has been paid to the use of avocado as a dietary supplement, in particular, for individuals involved in physical exercise training. therefore, this study aims to evaluate the effect of acute avocado pulp intake on cardiovascular and autonomic recovery subsequent to moderate exercise. Using a crossover, randomized, double-blind and placebocontrolled trial design, 16 healthy female adults underwent two protocols: Avocado pulp (600 mg in capsule) and placebo (600 mg starch in capsule). After the ingestion of Avocado pulp or placebo, the subjects were seated for 60 min at rest, followed by running on a treadmill at a submaximal level and then remained seated for 60 min during recovery from the exercise. Heart rate (HR), heart rate variability (HRV) [rMSSD, SD1, HF (ms 2)] and skin conductance were evaluated before and during exercise, as well as during recovery. HR, systolic blood pressure, HRV and skin conductance recovered faster when subjects were given avocado pulp prior to exercise. in conclusion, avocado pulp improved cardiovascular and autonomic recovery after exercise, suggesting a reduced risk of cardiovascular events after exertion. The current results support the beneficial effects of ingestion of avocado prior to submaximal treadmill running. The autonomic nervous system is controlled by central areas in the brain and brainstem 1,2. During exercise the autonomic nervous system is responsible for physiological changes required to meet the contending demands of skin blood flow (thermoregulation) and the functioning muscles (metabolic loads), to maintain blood pressure and optimal organ perfusion 1. This is key to keeping the body healthy under stressful conditions 1,2. In the first few seconds of exercise, reduction of parasympathetic activity increases heart rate (HR), followed by an elevation

“…A investigação atual inclui detalhes baseados no checklist CONSORT 2010, tais como: descrição de objetivos ou hipóteses, detalhes suficientes sobre as intervenções para permitir a replicação e descrição das limitações do ensaio. Estes são apenas alguns exemplos de toda a lista de verificação (Sousa et al, 2020;Schulz et al, 2010).…”

“…For instance, an investigation has evaluated the effect of acute avocado pulp intake on cardiovascular and autonomic recovery after moderate exercise. 34 Besides, avocado seeds have found to contain phenolic acids and flavonoids, which are well known to have protective activity against cardiovascular health. 35 Some earlier studies have also shown that avocado oil and avocado pulp extracts have beneficial effects on improving cardiovascular measures in rats.…”
