Abstract

ABSTRACTThe purpose of this study was to analyze the effect of the frequency of moderate-intensity aerobic exercise on body fat of female university students. A quasi experimental design was applied by involving 21 undergraduate students who were divided into three groups of treatments moderate-intensity aerobic exercise intervention for eight weeks. The first group was two times a week, the second group was three times a week, and third group was four times a week. Primary data collected was included subcutaneous fat (triceps, abdomen, and thigh). The results showed that the third group has significantly difference in reducing body fats, namely 6.6 cm triceps, 5.4 cm abdomen, and 9.4 cm thigh (p<0.05).Keywords: aerobic exercise, body fat, moderate-intensityABSTRAKTujuan penelitian adalah menganalisis pengaruh frekuensi senam aerobik intensitas sedang (low impact) terhadap lemak tubuh mahasiswi. Penelitian menggunakan desain quasi eksperimen dengan subjek berjumlah 21 mahasiswi, kemudian dibagi kedalam tiga kelompok perlakuan dengan melakukan senam aerobik intensitas sedang selama delapan minggu. Kelompok pertama diberikan perlakuan dua kali dalam seminggu, kelompok kedua tiga kali dalam seminggu dan kelompok ketiga diberikan perlakuan empat kali seminggu. Data primer terdiri atas lemak tubuh (trisep, abdomen, dan paha depan). Hasil penelitian menunjukkan pada kelompok tiga terdapat penurunan yang nyata (p<0,05) sebelum dan setelah perlakuan sebesar 6,6 cm trisep, 5,4 cm abdomen dan 9,4 cm paha depan.Kata kunci: aerobik, intensitas sedang, lemak tubuh

Abstract

ABSTRACTThe aimed of this study was to determine the differences intake of macro-nutrients (protein, fat, carbohydrates) and fiber with respect to their nutritional status of children aged 6-12 years. This study was used secondary data Riskesdas 2010. The number of subjects was 2,987 children aged 6-12 years in Sulawesi Island. Body Mass Index for Age (BMI/U) was used to measure the nutritional status. Independent sample t-test and analysis of variance were applied to answer the research questions. The result showed that most of subjects were male (58.7%), living in rural areas (50.2%), and with low economic status (54.1%). In regard to protein intake, most of the children age 6 years was about 80-99% Recommended Dietary Intake (RDA). On the contrary, most of children 7-9 years and 10-12 years were below 70% RDA. There were no differences intake of macro-nutrients (protein, fat, carbohydrates) and fiber to the nutritional status of children aged 6-12 years (p>0.05). This study found that most of the children were suffering macro-nutrients intake regardless their nutritional status. Therefore, we need to have a good program to monitor nutritional status of school children.Keywords: nutrient intake, nutritional status, school age children 6-12 yearABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan asupan zat gizi makro (protein, lemak, karbohidrat) dan serat terhadap status gizi pada anak usia 6-12 tahun. Penelitian ini menggunakan data sekunder Riskesdas 2010 dengan pendekatan cross-sectional. Subjek penelitian adalah anak usia 6-12 tahun dengan status gizi kurus, normal, dan gemuk menurut IMT/U di Pulau Sulawesi tahun 2010 berjumlah 2.087 orang. Pengujian statistik menggunakan independent sample t-test dan Anova. Sebagian besar subjek berjenis kelamin laki-laki (58,7%), tinggal di perdesaan (50,2%), dan berstatus ekonomi rendah (54,1%). Rata-rata asupan protein pada kelompok umur 6 tahun termasuk kategori sedang (80-99% AKG) namun pada usia 7-9 tahun dan usia 10-12 tahun termasuk kategori defisit (<70% AKG). Tidak terdapat perbedaan asupan zat gizi makro dan serat terhadap status gizi (IMT/U) di Pulau Sulawesi (p>0,05). Penelitian ini menemukan adanya keberagaman asupan dan status gizi anak usia sekolah. Oleh karenanya, diperlukan program pemantauan status gizi secara rutin di sekolah.Kata kunci: anak usia 6-12 tahun, asupan zat gizi, status gizi

Abstract

ABSTRACTThe present study aimed to analyze the association between body fatness measures, i.e. body mass index (BMI) and percent fat mass (% FM) with cardiorespiratory fitness (CRF) in young adults. Seventy five undergraduate students aged 19-21 years were included in this cross sectional study. Body composition was assessed by tetra polar Bioelectrical Impedance Analysis method, and CRF was determined as VO2 max level by conducting Balke test and flexibility by sit-and-reach test. Regression tests were performed to assess the associations between the body fatness measures and CRF. The mean (SD) % FM and BMI were 25.6 (8.3) % and 22.4 (4.2) kg/m2, respectively. Both BMI and % FM were inversely associated with VO2 max and flexibility. The associations of % FM with each CRF measure were stronger (% FM-VO2 max: R2=0.45, p<0.0001; % FM-flexibility: R2=0.16, p<0.0001) than those of BMI (BMI-VO2 max: R2= 0.12, p=0.002; BMI-flexibility: R2=0.07, p<0.0001). Including gender as a variable predictor greatly improved almost all associations. We suggest that %FM is a better predictor for VO2max than BMI. Further studies are needed to elucidate the relationships of body fatness measures adjusted for potential confounding factors with CRF measures other than VO2 max.Keywords: body mass index, cardiorespiratory fitness, percent fat massABSTRAKPenelitian ini bertujuan untuk menentukan hubungan antara persentase lemak tubuh (PLT) dan indeks massa tubuh (IMT) dengan kebugaran kardiorespiratorik (KKR) pada dewasa muda. Penelitian menggunakan desain potong lintang dengan melibatkan 75 orang mahasiswa usia 19-21 tahun. PLT ditentukan dengan metode tetra polar Bioelectrical Impedance dan KKR ditentukan dengan VO2max berdasarkan uji Balke dan fleksibilitas dengan uji sit-and-reach. Hubungan antara PLT dan IMT dengan KKR dianalisis dengan uji regresi. Rata-rata (standar deviasi) dari PLT dan IMT berturut-turut adalah 25,6 (8,3)% dan 22,4 (4,2) kg/m2. Baik PLT maupun IMT berbanding terbalik dengan nilai VO2 max dan fleksibilitas. Korelasi antara PLT dengan kedua komponen KKR lebih kuat (PLT-VO2 max: R2=0,45 p<0,0001; PLT-fleksibilitas: R2=0,16 p<0,0001) dibanding IMT (IMT-VO2 max: R2=0,12 p=0,002; IMT-fleksibilitas: R2=0,07 p<0,0001). Memasukkan gender sebagai prediktor variabel memperkuat semua korelasi kecuali antara PLT dan fleksibilitas. Diperlukan studi lebih lanjut untuk mempelajari hubungan antara komposisi tubuh termasuk faktor perancu potensial dengan fleksibilitas dan komponen KKR lainnya.Kata kunci: indeks massa tubuh, kebugaran kardiorespiratorik, persen lemak tubuh
