Pengaruh pemberian bubuk susu kacang hijau terhadap tekanan darah dan denyut nadi pasca pemulihan atlet sepakbola

Abstract

Background: Resistance exercise can cause microdamage to muscle tissue, leading to more severe damage over time. In particular, athletes who tend to exercise with moderate to heavy intensity are at a high risk of injury and have a longer recovery due to excessive fatigue during exercise. A proper nutritional strategy is needed to reduce the effects of exercise and accelerate recovery by supplementation with amino acids (BCAA). BCAAs are a branch-chain amino acid series of leucine, lysine, and isoleucine. Green beans are foods high in amino acids, such as lysine, valine, isoleucine, cysteine, methionine, and tryptophan.Objectives: This study aimed to investigate the effect of green bean milk powder on post-recovery blood pressure and pulse rate in football athletes.Method: The research used a quasi-experimental approach with a one-group pre-posttest control group design. The subjects in this study were 22 football athletes at BPPLOP Central Java, conducted in May 2023. The markers used in this study were post-recovery blood pressure and pulse rate. Blood pressure and pulse measurements were performed using the oscillometric method by placing the cuff on the upper arm, and the measurement results were observed on the monitor connected to the cuff on the Omron® digital tensimeter. Data were analyzed using an Independent Sample T-Test and Mann-Whitney U test at 95% CI.Results: Both groups of subjects in this study consisted of ages ranging from 15-19 years, body weight between 52-72 kg, height between 165-178 cm, nutritional status between normal-fat, percent body fat in the normal category, energy intake, carbohydrates, protein, and fat. At the same time, the energy and nutrient intake analysis results in each group showed that the subjects’ energy intake was still in the deficit or deficient group. In contrast, fat intake in each group was classified as excess. There was no significant difference in the provision of mung bean milk powder intervention before and after stages 1 and 2 of the study on the results of systolic blood pressure measurements (p= 0,844), diastolic blood pressure (p= 0,115) and post-recovery pulse rate (p= 0,972).Summary: Giving green bean milk powder at 25 g/day after exercising for eight days did not significantly affect blood pressure or post-recovery pulse rate.
