The purpose of this study is to compare VO2max, physical activity,nutritional status (BMI), and nutritional intake (energy, carbohydrate, protein, andfat) between cycling group and non-cycling group. This research is an ecologicalstudy. Data were collected from March-May 2013 in Bike to Work IndonesiaCommunity and colleges at FKM UI. The study showed that there weresignificant differences in VO2max between cycling group and non-cycling group(p= 0,028). The average of physical activity score is significantly higher (p=0,001) in cycling group. Both of group are suggested to increase their physicalactivity to maintenance cardiorespiratory fitness.

The purpose of this research was to compare height, physical activity, and nutritional intakes (energy, protein, carbohydrate, fat, vitamin A, vitamin D, vitamin C, calcium, iron, and zinc) between adolescent female swimmers and non-swimmers. This research was an ecological study. Data were collected from March to April 2013 in SMPI Al-Azhar 4 Kemandoran, GOR Senayan Swimming Pool, Simprug Pertamina Swimming Pool, and Cikini Swimming Pool with samples 26 adolescent swimmers and 26 adolescent non-swimmers. This study showed that height in adolescent female swimmers and non-swimmers were significantly different (p=0,041). Physical Activity was significantly different (p=0, 001) from adolescent swimmers and non swimmers. Mean of nutritional intakes in swimmers were significantly higher than non-swimmers for protein (p=0, 018), vitamin A (p=0, 006), calcium (p=0, 001), iron (p=0, 001), and zinc (p=0, 000). It is recommended for SMPI Al-Azhar 4 Kemandoran to include swimming as a part of the school’s curriculumm. Swim clubs and schools are suggested to cooperate to facilitate students with swimming lessons.
Obesitas sentral merupakan salah satu masalah kesehatan utama secara global. Obesitas sentral merupakan penumpukan lemak dalam tubuh bagian perut yang berhubungan dengan beragam masalah kesehatan, seperti diabetes melitus, hipertensi, penyakit kardiovaskular dan beberapa jenis kanker. Tujuan utama penelitian ini adalah untuk mengetahui faktor dominan yang berhubungan dengan obesitas sentral pada anggota polisi laki-laki di Kepolisian Resort X. Penelitian ini menggunakan desain cross-sectional dengan jumlah sampel 150 orang menggunakan metode simple random sampling yang dilakukan di Kepolisian Resort X Jawa Timur pada bulan Mei-Juni 2024. Penelitian ini mengolah data primer yang didapatkan dari pengukuran antropometri dan wawancara. Data dianalisis secara bivariat dengan uji chi-square dan secara multivariat menggunakan regresi logistik ganda. Proporsi kejadian obesitas pada anggota polisi laki-laki di Kepolisian Resort X sebanyak 76%. Hasil analisis bivariat menunjukkan terdapat hubungan yang signifikan antara status pernikahan, aktivitas fisik, kebiasaan merokok, asupan energi, asupan karbohidrat, asupan lemak, dan asupan serat terhadap kejadian obesitas sentral pada anggota polisi. Sementara itu, tidak terdapat hubungan signifikan antara usia, riwayat obesitas, tingkat pendidikan, pangkat pekerjaan, durasi tidur, tingkat stress, dan asupan protein terhadap kejadian obesitas sentral. Sedangkan berdasarkan analisis multivariat menunjukkan bahwa asupan energi berkontribusi besar terhadap kejadian obesitas sentral dengan OR = 26,276 (95% CI: 8,191 – 84,290) yang berarti asupan energi berlebih dapat meningkatkan risiko obesitas sentral sebesar 26,2 kali daripada responden dengan tingkat asupan karbohidrat yang cukup.
Central obesity is the accumulation of fat in the abdominal part of the body which is associated with various health problems, such as diabetes mellitus, hypertension, cardiovascular disease and several types of cancer. The aim of this study is to determine the dominant factors associated with central obesity toward male police officers at Resort X Police. This research used a cross-sectional design with a sample size of 150 people using a simple random sampling method which conducted at Police Resort X East Java in May-June 2024. This research processed primary data obtained from anthropometric measurements and interviews. Data were analyzed bivariately using the chi-square test and multivariately using multiple logistic regression. The proportion of obesity among male police officers at Resort X Police is 76%. The results of bivariate analysis showed that there was a significant relationship between marital status, physical activity, smoking habits, energy intake, carbohydrate intake, fat intake, and fiber intake toward central obesity among police officers. Meanwhile, there was no significant relationship between age, history of obesity, education level, job rank, sleep duration, stress level, and protein intake on the incidence of central obesity. On the other hand, based on multivariate analysis, it shows that carbohydrate intake contributes greatly to the occurence of central obesity with OR = 26,276 (95% CI: 8,191 – 84,290) which means that excessive carbohydrate intake can increase the risk of central obesity by 26,27 times compared to respondents with sufficient levels of carbohydrate intake.

Low levels of fitness in children and adolescents are at increased risk of cardiovascular disease. Some studies suggest that fitness levels in children and adolescents was still relatively low and there is no standard model of prediction in determining the fitness status based on VO2max in Indonesia. The primary purpose of this study was to develop fitness (VO2max) prediction model for 9-11 years in selected elementary student in East Jakarta. This study used cross-sectional design, variable of dependent was fitness and variable of independent was sex, nutritional intake, nutritional status, and physical activity. The fitness test measured by 20m shuttle run test. The sample was 118 students. The mean value of VO2max was higher in SD 2 than SD 1 (SD 2 = 41.49 ml/kg/min; SD 1 = 39.99 ml/kg/min). In bivariat analysis, there was a differences fitness between male and female, which is male was more fit than female. Than nutritional intake (energy, protein, carbohydrate, thiamin, and iron), nutritional status (BMI/A), and physical activity was significantly related to fitness (VO2max). Result of multiple regression analysis showed that variable sex and nutritional status was the dominant predictor controlled by the interaction between the two variable. Adequate intake, good nutritional status (BMI/A), and increase physical activity are required to improve fitness level.
