Objective:
This study aimed to evaluate the effects of macaiba pulp on physical, biochemical, intestinal health, and oxidative stress parameters in exercised rats.
Methodology:
Forty-four male rats were divided into four groups (n= 11): sedentary control (CT), exercised control (CT-EX), sedentary macaiba (MC), and exercised macaiba (MC-EX). MC and MC-EX groups received 1000 mg/kg/day of macaiba pulp, while CT and CT-EX received distilled water for eight weeks. Exercised animals underwent swimming for five days a week, beginning with 10 min and progressing to 60 min. Blood was collected to measure cholesterol (TC, HDL, LDL, VLDL), glucose, urea, liver enzymes (AST, ALT), and cardiovascular risk factors. Liver samples were analyzed for malonaldehyde (MDA), total fat, and cholesterol, while feces were collected for metagenome analysis. Body fat and adiposity index were also measured.
Results:
Macaiba-treated groups showed improved gut microbiome balance, reduced TC, LDL, VLDL, glucose, urea, liver enzymes, cardiovascular risks, body fat, MDA, and liver fat, with an increase in HDL.
Conclusion:
Macaiba pulp effectively improved biochemical parameters, reduced lipid peroxidation from exercise, and lowered adipose tissue and cardiovascular risks.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
