Abstract

Indonesia has an increasing number of obese people every year. Risk factors and complications caused by obesity can increase morbidity and mortality in the community. One of factors causing the increasing number of obese people is caused by the decreasing level of physical activities done by Indonesian people.This study aims to determine the effect of physical activity levels on the risk of obesity. The study used an observational analytic case control design. Subjects were chosen through a purposive sampling method. The population was young adults in Surabaya. The sample of the study included 97 obese adults and 97 non-obese adults. The study was conducted in March - July 2018 in South Surabaya through distributing questionnaires to two groups. The questionnaire given used the Global Physical Activity Questionnaire (GPAQ). The results showed that physical activity performed by adult age group of obesity was mostly classified as low activity (59,8%), while non-obese adult age group was mostly included in medium activity (56,6%).This shows a significant difference in physical activity between obese and non-obese groups (p=0,047). It can be concluded that decreased levels of physical activity may increase the risk of obesity in adult.

Abstract

Diabetes mellitus (DM) is one of the global health problems and in the top 4th ranks as the main cause of death in developing countries (IDF, 2015). The pathogenesis of type II DM involves abnormalities in insulin secretion and activity that leads to insulin resistance. This research aims to study the efficacy of celery (Apiumgraveolens) as a prevention of insulin resistance. In this study, the samples were 45 Wistar rats (Rattus norvegicus), male sex, aged 4-6 weeks, weight 150-175 grams,and had normal fasting blood glucose levels by tested before treatment. The experimental animals were divided into 5 groups, K1 was negative control group (insulin resistance by given 20% fructose 1,86 g/kg BW PO qDay);K2 was positive control group (those given 20% fructose 1,86 g/kg BW PO qDayand standard insulin resistance therapy metformin 500 mg/kg BW PO qDay); the K3 treatment group was given 20% fructose 1,86 g/kg BW PO qDay and celery extract 200 mg/kg BW PO qDay; the K4 treatment group was given fructose 20% 1,86 mg/kg BW PO qDay and celery extract 400 mg/kg BW PO qDay; and the K5 treatment group was given fructose 20% 1,86 mg/kg BW PO qDay and celery extract 600 mg/kg BW PO qDay. The treatment had been given every day for 60 days.Fasting blood glucose levels were measured using a Glucometer. Fasting blood insulin levels were measured using ELISA, HOMA-IR was calculated using a standardized formula, and GLUT4 protein expression was measured using immunohistochemistry. It the end of the intervention, there was a significant decreased in fasting blood glucose (FBG) in K4 group compared with K1 (p <0.05), insulin resistance in K1 was characterized by a higher HOMA-IR value compared to the therapy group, especially K4 and K5 (p <0.05). There was an increase in GLUT-4 expression on K4 and K5 compared with K1 (p <0.05). It can be concluded that celery extract has antihyperglycemia effect and furthermore it can prevent insulin resistance condition.

Abstract

Abstract--Insulin resistance underlies the pathogenesis of chronic disease, such as diabetes mellitus which has high morbidity and mortality rate. Insulin resistance is a pathological condition when cells fail to respond normally to the insulin hormone, because of insulin signaling pathway disruption. Bound between insulin and insulin’s receptor cannot phosphorylate tyrosine and fail to activate insulin receptor substrate-1 (IRS-1). This failure decrease Glucose transporter-4 (GLUT-4) expression on the skeletal muscle’s cell membrane, that leads to decrease glucose influx and increase blood glucose level. A routine physical training which does according to adequate training dose, will activate adenosin 5’monophosphate-activated protein kinase (AMPK) and lead to the translocation of GLUT-4 vesicles without insulin and insulin’s receptor bonding.GLUT-4 expression on the skeletal muscle’s cell membrane which is stimulated by muscle contraction will increase glucose influx and decrease blood glucose level. Keywords: insulin resistance; physical training; insulin signaling pathway Abstrak--Resistensi insulin merupakan penyebab yang mendasari terjadinya penyakit kronis seperti diabetes melitus yang memiliki angka morbiditas dan mortalitas tinggi.Resistensi insulin merupakan keadaan patologis dimana terjadi kegagalan respon seluler terhadap hormon insulin akibat gangguan pada jalur sinyal insulin.Ikatan insulin pada reseptornya tidak dapat menyebabkan fosforilasi tirosin sehingga tidak dapat mengaktivasi insulin receptor substrate-1 (IRS-1). Kegagalan aktivasi tersebut akan menyebabkan penurunan ekspresi Glucose transporter-4 (GLUT-4) pada membran sel otot rangka sehingga ambilan glukosa oleh sel menurun dan glukosa darah meningkat. Latihan fisik yang dilakukan secara rutin, teratur dan sesuai dengan dosis latihan yang tepat dapat mengaktivasi adenosin 5’monophosphate-activated protein kinase (AMPK), sehingga menyebabkan translokasi vesikel berisi GLUT-4, tanpa melalui ikatan insulin dengan reseptornya. Ekspresi GLUT-4 pada membran sel yang dirangsang oleh kontraksi otot akan meningkatkan ambilan glukosa dan menurunkan glukosa darah. Kata kunci: resistensi insulin; latihan fisik; jalur sinyal insulin
